Gitea is a community managed lightweight code hosting solution written in Go. It is published under the MIT license.
Introduction
This helm chart has taken some inspiration from jfelten's helm chart. Yet it takes a completely different approach in providing a database and cache with dependencies. Additionally, this chart allows to provide LDAP and admin user configuration with values.
Update and versioning policy
The Gitea helm chart versioning does not follow Gitea's versioning. The latest chart version can be looked up in https://dl.gitea.com/charts or in the repository releases.
The chart aims to follow Gitea's releases closely.
There might be times when the chart is behind the latest Gitea release.
This might be caused by different reasons, most often due to time constraints of the maintainers (remember, all work here is done voluntarily in the spare time of people).
If you're eager to use the latest Gitea version earlier than this chart catches up, then change the tag in values.yaml to the latest Gitea version.
Note that besides the exact Gitea version one can also use the :1 tag to automatically follow the latest Gitea version.
This should be combined with image.pullPolicy: "Always".
Important: Using the :1 will also automatically jump to new minor release (e.g. from 1.13 to 1.14) which may eventually cause incompatibilities if major/breaking changes happened between these versions.
This is due to Gitea not strictly following semantic versioning as breaking changes do not increase the major version.
I.e., "minor" version bumps are considered "major".
Yet most often no issues will be encountered and the chart maintainers aim to communicate early/upfront if this would be the case.
Dependencies
Gitea is most performant when run with an external database and cache. This chart provides those dependencies via sub-charts. Users can also configure their own external providers via the configuration.
HA Dependencies
These dependencies are enabled by default:
- PostgreSQL HA (Bitnami PostgreSQL-HA)
- Redis-Cluster (Bitnami Redis-Cluster)
Non-HA Dependencies
Alternatively, the following non-HA replacements are available:
- PostgreSQL (Bitnami PostgreSQL)
- Redis (Bitnami Redis)
Dependency Versioning
Updates of sub-charts will be incorporated into the Gitea chart as they are released. The reasoning behind this is that new users of the chart will start with the most recent sub-chart dependency versions.
Note If you want to stay on an older appVersion of a sub-chart dependency (e.g. PostgreSQL), you need to override the image tag in your values.yaml file.
In fact, we recommend to do so right from the start to be independent of major sub-chart dependency changes as they are released.
There is no need to update to every new PostgreSQL major version - you can happily skip some and do larger updates when you are ready for them.
We recommend to use a rolling tag like :<majorVersion>-debian-<debian major version> to incorporate minor and patch updates for the respective major version as they are released.
Alternatively you can also use a versioning helper tool like renovate.
Please double-check the image repository and available tags in the sub-chart:
and look up the image tag which fits your needs on Dockerhub.
Installing
helm repo add gitea-charts https://dl.gitea.com/charts/
helm repo update
helm install gitea gitea-charts/gitea
Alternatively, the chart can also be installed from Dockerhub (since v9.6.0)
helm install gitea oci://registry-1.docker.io/giteacharts/gitea
When upgrading, please refer to the Upgrading section at the bottom of this document for major and breaking changes.
High Availability
Since version 9.0.0 this chart supports running Gitea and it's dependencies in HA mode. Care must be taken for production use as not all implementation details of Gitea core are officially HA-ready yet.
Deploying a HA-ready Gitea instance requires some effort including using HA-ready dependencies. See the HA Setup document for more details.
Configuration
Gitea offers lots of configuration options. This is fully described in the Gitea Cheat Sheet.
gitea:
config:
APP_NAME: "Gitea: With a cup of tea."
repository:
ROOT: "~/gitea-repositories"
repository.pull-request:
WORK_IN_PROGRESS_PREFIXES: "WIP:,[WIP]:"
Default Configuration
This chart will set a few defaults in the Gitea configuration based on the service and ingress settings.
All defaults can be overwritten in gitea.config.
INSTALL_LOCK is always set to true, since we want to configure Gitea with this helm chart and everything is taken care of.
All default settings are made directly in the generated app.ini, not in the Values.
Database defaults
If a builtIn database is enabled the database configuration is set automatically.
For example, PostgreSQL builtIn will appear in the app.ini as:
[database]
DB_TYPE = postgres
HOST = RELEASE-NAME-postgresql.default.svc.cluster.local:5432
NAME = gitea
PASSWD = gitea
USER = gitea
Server defaults
The server defaults are a bit more complex.
If ingress is enabled, the ROOT_URL, DOMAIN and SSH_DOMAIN will be set accordingly.
HTTP_PORT always defaults to 3000 as well as SSH_PORT to 22.
[server]
APP_DATA_PATH = /data
DOMAIN = git.example.com
HTTP_PORT = 3000
PROTOCOL = http
ROOT_URL = http://git.example.com
SSH_DOMAIN = git.example.com
SSH_LISTEN_PORT = 22
SSH_PORT = 22
ENABLE_PPROF = false
Metrics defaults
The Prometheus /metrics endpoint is disabled by default.
[metrics]
ENABLED = false
Actions defaults
The Gitea Actions are disabled by default in the chart, unless actions.enabled is set to true, which installs an act_runner Statefulset along Gitea.
If you want to activate Gitea Actions without installing the runner, use the gitea.config like so:
gitea:
config:
# [... ]
actions:
ENABLED: true
```
#### Rootless Defaults
If `.Values.image.rootless: true`, then the following will occur. In case you use `.Values.image.fullOverride`, check that this works in your image:
- `$HOME` becomes `/data/gitea/git`
[see deployment.yaml](./templates/gitea/deployment.yaml) template inside (init-)container "env" declarations
- `START_SSH_SERVER: true` (Unless explicity overwritten by `gitea.config.server.START_SSH_SERVER`)
[see \_helpers.tpl](./templates/_helpers.tpl) in `gitea.inline_configuration.defaults.server` definition
- `SSH_LISTEN_PORT: 2222` (Unless explicity overwritten by `gitea.config.server.SSH_LISTEN_PORT`)
[see \_helpers.tpl](./templates/_helpers.tpl) in `gitea.inline_configuration.defaults.server` definition
- `SSH_LOG_LEVEL` environment variable is not injected into the container
[see deployment.yaml](./templates/gitea/deployment.yaml) template inside container "env" declarations
#### Session, Cache and Queue
The session, cache and queue settings are set to use the built-in Redis Cluster sub-chart dependency.
If Redis Cluster is disabled, the chart will fall back to the Gitea defaults which use "memory" for `session` and `cache` and "level" for `queue`.
While these will work and even not cause immediate issues after startup, **they are not recommended for production use**.
Reasons being that a single pod will take on all the work for `session` and `cache` tasks in its available memory.
It is likely that the pod will run out of memory or will face substantial memory spikes, depending on the workload.
External tools such as `redis-cluster` or `memcached` handle these workloads much better.
### Single-Pod Configurations
If HA is not needed/desired, the following configurations can be used to deploy a single-pod Gitea instance.
1. For a production-ready single-pod Gitea instance without external dependencies (using the chart dependency `postgresql` and `redis`):
<details>
<summary>values.yml</summary>
```yaml
redis-cluster:
enabled: false
redis:
enabled: true
postgresql:
enabled: true
postgresql-ha:
enabled: false
persistence:
enabled: true
gitea:
config:
database:
DB_TYPE: postgres
indexer:
ISSUE_INDEXER_TYPE: bleve
REPO_INDEXER_ENABLED: true
```
</details>
2. For a minimal DEV installation (using the built-in sqlite DB instead of Postgres):
This will result in a single-pod Gitea instance _without any dependencies and persistence_.
**Do not use this configuration for production use**.
<details>
<summary>values.yml</summary>
```yaml
redis-cluster:
enabled: false
redis:
enabled: false
postgresql:
enabled: false
postgresql-ha:
enabled: false
persistence:
enabled: false
gitea:
config:
database:
DB_TYPE: sqlite3
session:
PROVIDER: memory
cache:
ADAPTER: memory
queue:
TYPE: level
```
</details>
### Additional _app.ini_ settings
> **The [generic](https://docs.gitea.com/administration/config-cheat-sheet#overall-default)
> section cannot be defined that way.**
Some settings inside _app.ini_ (like passwords or whole authentication configurations) must be considered sensitive and therefore should not be passed via plain text inside the _values.yaml_ file.
In times of _GitOps_ the values.yaml could be stored in a Git repository where sensitive data should never be accessible.
The Helm Chart supports this approach and let the user define custom sources like
Kubernetes Secrets to be loaded as environment variables during _app.ini_ creation or update.
```yaml
gitea:
additionalConfigSources:
- secret:
secretName: gitea-app-ini-oauth
- configMap:
name: gitea-app-ini-plaintext
```
This would mount the two additional volumes (`oauth` and `some-additionals`) from different sources to the init container where the _app.ini_ gets updated.
All files mounted that way will be read and converted to environment variables and then added to the _app.ini_ using [environment-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini).
The key of such additional source represents the section inside the _app.ini_.
The value for each key can be multiline ini-like definitions.
In example, the referenced `gitea-app-ini-plaintext` could look like this.
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: gitea-app-ini-plaintext
data:
session: |
PROVIDER=memory
SAME_SITE=strict
cron.archive_cleanup: |
ENABLED=true
```
Or when using a Kubernetes secret, having the same data structure:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-security-related-configuration
type: Opaque
stringData:
security: |
PASSWORD_COMPLEXITY=off
session: |
SAME_SITE=strict
```
#### User defined environment variables in app.ini
Users are able to define their own environment variables, which are loaded into the containers.
We also support to directly interact with the generated _app.ini_.
To inject self defined variables into the _app.ini_ a certain format needs to be honored.
This is described in detail on the [env-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini) page.
Prior to Gitea 1.20 and Chart 9.0.0 the helm chart had a custom prefix `ENV_TO_INI`.
After the support for a custom prefix was removed in Gite core, the prefix was changed to `GITEA`.
For example a database setting needs to have the following format:
```yaml
gitea:
additionalConfigFromEnvs:
- name: GITEA__DATABASE__HOST
value: my.own.host
- name: GITEA__DATABASE__PASSWD
valueFrom:
secretKeyRef:
name: postgres-secret
key: password
```
Priority (highest to lowest) for defining app.ini variables:
1. Environment variables prefixed with `GITEA`
1. Additional config sources
1. Values defined in `gitea.config`
### External Database
Any external database listed in [https://docs.gitea.com/installation/database-prep](https://docs.gitea.com/installation/database-prep) can be used instead of the built-in PostgreSQL.
In fact, it is **highly recommended** to use an external database to ensure a stable Gitea installation longterm.
If an external database is used, no matter which type, make sure to set `postgresql.enabled` to `false` to disable the use of the built-in PostgreSQL.
```yaml
gitea:
config:
database:
DB_TYPE: mysql
HOST: <mysql HOST>
NAME: gitea
USER: root
PASSWD: gitea
SCHEMA: gitea
postgresql:
enabled: false
postgresql-ha:
enabled: false
```
### Ports and external url
By default port `3000` is used for web traffic and `22` for ssh.
Those can be changed:
```yaml
service:
http:
port: 3000
ssh:
port: 22
```
This helm chart automatically configures the clone urls to use the correct ports.
You can change these ports by hand using the `gitea.config` dict.
However you should know what you're doing.
### ClusterIP
By default the `clusterIP` will be set to `None`, which is the default for headless services.
However if you want to omit the clusterIP field in the service, use the following values:
```yaml
service:
http:
type: ClusterIP
port: 3000
clusterIP:
ssh:
type: ClusterIP
port: 22
clusterIP:
```
### SSH and Ingress
If you're using ingress and want to use SSH, keep in mind, that ingress is not able to forward SSH Ports.
You will need a LoadBalancer like `metallb` and a setting in your ssh service annotations.
```yaml
service:
ssh:
annotations:
metallb.universe.tf/allow-shared-ip: test
```
### SSH on crio based kubernetes cluster
If you use `crio` as container runtime it is not possible to read from a remote repository.
You should get an error message like this:
```bash
$ git clone git@k8s-demo.internal:admin/test.git
Cloning into 'test'...
Connection reset by 192.168.179.217 port 22
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
```
To solve this problem add the capability `SYS_CHROOT` to the `securityContext`.
More about this issue [here](https://gitea.com/gitea/helm-chart/issues/161).
### Cache
The cache handling is done via `redis-cluster` (via the `bitnami` chart) by default.
This deployment is HA-ready but can also be used for single-pod deployments.
By default, 6 replicas are deployed for a working `redis-cluster` deployment.
Many cloud providers offer a managed redis service, which can be used instead of the built-in `redis-cluster`.
```yaml
redis-cluster:
enabled: true
```
⚠️ The redis charts [do not work well with special characters in the password](https://gitea.com/gitea/helm-chart/issues/690).
Consider omitting such or open an issue in the Bitnami repo and let us know once this got fixed.
### Persistence
Gitea will be deployed as a deployment.
By simply enabling the persistence and setting the storage class according to your cluster everything else will be taken care of.
The following example will create a PVC as a part of the deployment.
Please note, that an empty `storageClass` in the persistence will result in kubernetes using your default storage class.
If you want to use your own storage class define it as follows:
```yaml
persistence:
enabled: true
storageClass: myOwnStorageClass
```
If you want to manage your own PVC you can simply pass the PVC name to the chart.
```yaml
persistence:
enabled: true
claimName: MyAwesomeGiteaClaim
```
In case that persistence has been disabled it will simply use an empty dir volume.
PostgreSQL handles the persistence in the exact same way.
You can interact with the postgres settings as displayed in the following example:
```yaml
postgresql:
persistence:
enabled: true
claimName: MyAwesomeGiteaPostgresClaim
```
### Admin User
This chart enables you to create a default admin user.
It is also possible to update the password for this user by upgrading or redeploying the chart.
It is not possible to delete an admin user after it has been created.
This has to be done in the ui.
You cannot use `admin` as username.
```yaml
gitea:
admin:
username: "MyAwesomeGiteaAdmin"
password: "AReallyAwesomeGiteaPassword"
email: "gi@tea.com"
```
You can also use an existing Secret to configure the admin user:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-admin-secret
type: Opaque
stringData:
username: MyAwesomeGiteaAdmin
password: AReallyAwesomeGiteaPassword
```
```yaml
gitea:
admin:
existingSecret: gitea-admin-secret
```
Whether you use the existing Secret or specify a user name and password, there are three modes for how the admin user password is created or set.
- `keepUpdated` (the default) will set the admin user password, and reset it to the defined value every time the pod is recreated.
- `initialOnlyNoReset` will set the admin user password when creating it, but never try to update the password.
- `initialOnlyRequireReset` will set the admin user password when creating it, never update it, and require that the password be changed at the initial login.
These modes can be set like the following:
```yaml
gitea:
admin:
passwordMode: initialOnlyRequireReset
```
### LDAP Settings
Like the admin user the LDAP settings can be updated.
All LDAP values from <https://docs.gitea.com/administration/command-line#admin> are available.
Multiple LDAP sources can be configured with additional LDAP list items.
```yaml
gitea:
ldap:
- name: MyAwesomeGiteaLdap
securityProtocol: unencrypted
host: "127.0.0.1"
port: "389"
userSearchBase: ou=Users,dc=example,dc=com
userFilter: sAMAccountName=%s
adminFilter: CN=Admin,CN=Group,DC=example,DC=com
emailAttribute: mail
bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
bindPassword: JustAnotherBindPw
usernameAttribute: CN
publicSSHKeyAttribute: publicSSHKey
```
You can also use an existing secret to set the `bindDn` and `bindPassword`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-ldap-secret
type: Opaque
stringData:
bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
bindPassword: JustAnotherBindPw
```
```yaml
gitea:
ldap:
- existingSecret: gitea-ldap-secret
...
```
⚠️ Some options are just flags and therefore don't have any values.
If they are defined in `gitea.ldap` configuration, they will be passed to the Gitea CLI without any value.
Affected options:
- notActive
- skipTlsVerify
- allowDeactivateAll
- synchronizeUsers
- attributesInBind
### OAuth2 Settings
Like the admin user, OAuth2 settings can be updated and disabled but not deleted.
Deleting OAuth2 settings has to be done in the ui.
All OAuth2 values, which are documented [here](https://docs.gitea.com/administration/command-line#admin), are
available.
Multiple OAuth2 sources can be configured with additional OAuth list items.
```yaml
gitea:
oauth:
- name: "MyAwesomeGiteaOAuth"
provider: "openidConnect"
key: "hello"
secret: "world"
autoDiscoverUrl: "https://gitea.example.com/.well-known/openid-configuration"
#useCustomUrls:
#customAuthUrl:
#customTokenUrl:
#customProfileUrl:
#customEmailUrl:
```
You can also use an existing secret to set the `key` and `secret`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-oauth-secret
type: Opaque
stringData:
key: hello
secret: world
```
```yaml
gitea:
oauth:
- name: "MyAwesomeGiteaOAuth"
existingSecret: gitea-oauth-secret
...
```
## Configure commit signing
When using the rootless image the gpg key folder is not persistent by default.
If you consider using signed commits for internal Gitea activities (e.g. initial commit), you'd need to provide a signing key.
Prior to [PR186](https://gitea.com/gitea/helm-chart/pulls/186), imported keys had to be re-imported once the container got replaced by another.
The mentioned PR introduced a new configuration object `signing` allowing you to configure prerequisites for commit signing.
By default this section is disabled to maintain backwards compatibility.
```yaml
signing:
enabled: false
gpgHome: /data/git/.gnupg
```
Regardless of the used container image the `signing` object allows to specify a private gpg key.
Either using the `signing.privateKey` to define the key inline, or refer to an existing secret containing the key data by using `signing.existingSecret`.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: custom-gitea-gpg-key
type: Opaque
stringData:
privateKey: |-
-----BEGIN PGP PRIVATE KEY BLOCK-----
...
-----END PGP PRIVATE KEY BLOCK-----
```
```yaml
signing:
existingSecret: custom-gitea-gpg-key
```
To use the gpg key, Gitea needs to be configured accordingly.
A detailed description can be found in the [official Gitea documentation](https://docs.gitea.com/administration/signing#general-configuration).
## Metrics and profiling
A Prometheus `/metrics` endpoint on the `HTTP_PORT` and `pprof` profiling endpoints on port 6060 can be enabled under `gitea`.
Beware that the metrics endpoint is exposed via the ingress, manage access using ingress annotations for example.
To deploy the `ServiceMonitor`, you first need to ensure that you have deployed `prometheus-operator` and its [CRDs](https://github.com/prometheus-operator/prometheus-operator#customresourcedefinitions).
```yaml
gitea:
metrics:
enabled: true
serviceMonitor:
enabled: true
config:
server:
ENABLE_PPROF: true
```
## Pod annotations
Annotations can be added to the Gitea pod.
```yaml
gitea:
podAnnotations: {}
```
## Themes
Custom themes can be added via k8s secrets and referencing them in `values.yaml`.
The [http provider](https://registry.terraform.io/providers/hashicorp/http/latest/docs/data-sources/http) is useful here.
```yaml
extraVolumes:
- name: gitea-themes
secret:
secretName: gitea-themes
extraVolumeMounts:
- name: gitea-themes
readOnly: true
mountPath: "/data/gitea/public/assets/css"
```
The secret can be created via `terraform`:
```hcl
resource "kubernetes_secret" "gitea-themes" {
metadata {
name = "gitea-themes"
namespace = "gitea"
}
data = {
"my-theme.css" = data.http.gitea-theme-light.body
"my-theme-dark.css" = data.http.gitea-theme-dark.body
"my-theme-auto.css" = data.http.gitea-theme-auto.body
}
type = "Opaque"
}
data "http" "gitea-theme-light" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
data "http" "gitea-theme-dark" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
data "http" "gitea-theme-auto" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
```
or natively via `kubectl`:
```bash
kubectl create secret generic gitea-themes --from-file={{FULL-PATH-TO-CSS}} --namespace gitea
```
## Renovate
To be able to use a digest value which is automatically updated by `Renovate` a [customManager](https://docs.renovatebot.com/modules/manager/regex/) is required.
Here's an examplary `values.yml` definition which makes use of a digest:
```yaml
image:
repository: gitea/gitea
tag: 1.20.2
digest: sha256:6e3b85a36653894d6741d0aefb41dfaac39044e028a42e0a520cc05ebd7bfc3f
```
By default Renovate adds digest after the `tag`.
To comply with the Gitea helm chart definition of the digest parameter, a "customManagers" definition is required:
```json
"customManagers": [
{
"customType": "regex",
"description": "Apply an explicit gitea digest field match",
"fileMatch": ["values\\.ya?ml"],
"matchStrings": ["(?<depName>gitea\\/gitea)\\n(?<indentation>\\s+)tag: (?<currentValue>[^@].*?)\\n\\s+digest: (?<currentDigest>sha256:[a-f0-9]+)"],
"datasourceTemplate": "docker",
"autoReplaceStringTemplate": "{{depName}}\n{{indentation}}tag: {{newValue}}\n{{indentation}}digest: {{#if newDigest}}{{{newDigest}}}{{else}}{{{currentDigest}}}{{/if}}"
}
]
```

Expected workflow is: Fork -> Patch -> Push -> Pull Request
See [CONTRIBUTORS GUIDE](CONTRIBUTING.md) for details.
## Upgrading
This section lists major and breaking changes of each Helm Chart version.
Please read them carefully to upgrade successfully, especially the change of the **default database backend**!
If you miss this, blindly upgrading may delete your Postgres instance and you may lose your data!
<details>
<summary>To 10.0.0</summary>
<!-- prettier-ignore-start -->
<!-- markdownlint-disable-next-line -->
**Breaking changes**
<!-- prettier-ignore-end -->
- Update PostgreSQL sub-chart dependencies to appVersion 16.x
- Update to sub-charts versioning approach: Users are encouraged to pin the version tag of the sub-chart dependencies to a major appVersion.
This avoids issues during chart upgrades and allows to incorporate new sub-chart versions as they are released.
Please see the new [README section describing the versioning approach for sub-chart versions](#dependency-versioning).
</details>
<details>
<summary>To 9.6.0</summary>
Chart 9.6.0 ships with Gitea 1.21.0.
While there are no breaking changes in the chart, please check the changes of the [1.21 release blog post](https://blog.gitea.com/release-of-1.21.0/).
</details>
<details>
<summary>To 9.0.0</summary>
This chart release comes with many breaking changes while aiming for a HA-ready setup.
Please go through all of them carefully to perform a successful upgrade.
Here's a brief summary again, followed by more detailed migration instructions:
- Switch from `Statefulset` to `Deployment`
- Switch from `Memcached` to `redis-cluster` as the default session and queue provider
- Switch from `postgres` to `postgres-ha` as the default database provider
- A chart-internal PVC bootstrapping logic
- New `persistence.mount`: whether to mount an existent PVC (even if not creating it)
- New `persistence.create`: whether to create a new PVC
- Renamed `persistence.existingClaim` to `persistence.claimName`
While not required, we recommend to start with a RWX PV for new installations.
A RWX volume is required for installation aiming for HA.
If you want to stay with a pre-existing RWO PV, you need to set
- `persistence.mount=true`
- `persistence.create=false`
- `persistence.claimName` to the name of your existing PVC.
If you do not, Gitea will create a new PVC which will in turn create a new PV.
If this happened to you by accident, you can still recover your data by setting using the settings from above in a subsequent run.
If you want to stay with a `memcache` instead of `redis-cluster`, you need to deploy `memcache` manually (e.g. from [bitnami](https://github.com/bitnami/charts/tree/main/bitnami/memcached)) and set
- `cache.HOST = "<memcache connection string>"`
- `cache.ADAPTER = "memcache"`
- `session.PROVIDER = "memcache"`
- `session.PROVIDER_CONFIG = "<memcache connection string>"`
- `queue.TYPE = "memcache"`
- `queue.CONN_STR = "<memcache connection string>"`
The `memcache` connection string has the scheme `memcache://<memcache service name>:<memcache service port>`, e.g. `gitea-memcached.gitea.svc.cluster.local:11211`.
The first item here (`<memcache service name>`) will be different compared to the example if you deploy `memcache` yourself.
The above changes are motivated by the idea to tidy dependencies but also have HA-ready ones at the same time.
The previous `memcache` default was not HA-ready, hence we decided to switch to `redis-cluster` by default.
If you are coming from an existing deployment and [#356](https://gitea.com/gitea/helm-chart/issues/356) is still open, you need to set the config sections for `cache`, `session` and `queue` explicitly:
```yaml
gitea:
config:
session:
PROVIDER: redis-cluster
PROVIDER_CONFIG: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
cache:
ENABLED: true
ADAPTER: redis-cluster
HOST: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
queue:
TYPE: redis
CONN_STR: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
```
<!-- prettier-ignore-start -->
<!-- markdownlint-disable-next-line -->
**Switch to rootless image by default**
<!-- prettier-ignore-end -->
If you are facing errors like `WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED` due to this automatic transition:
Have a look at [this discussion](https://gitea.com/gitea/helm-chart/issues/487#issue-220660) and either set `image.rootless: false` or manually update your `~/.ssh/known_hosts` file(s).
<!-- prettier-ignore-start -->
<!-- markdownlint-disable-next-line -->
**Transitioning from a RWO to RWX Persistent Volume**
<!-- prettier-ignore-end -->
If you want to switch to a RWX volume and go for HA, you need to
1. Backup the data stored under `/data`
2. Let the chart create a new RWX PV (or do it statically yourself)
3. Restore the backup to the same location in the new PV
<!-- prettier-ignore-start -->
<!-- markdownlint-disable-next-line -->
**Transitioning from Postgres to Postgres HA**
<!-- prettier-ignore-end -->
If you are running with a non-HA PG DB from a previous chart release, you need to set
- `postgresql-ha.enabled=false`
- `postgresql.enabled=true`
This is needed to stay with your existing single-instance DB (as the HA-variant is the new default).
<!-- prettier-ignore-start -->
<!-- markdownlint-disable-next-line -->
**Change of env-to-ini prefix**
<!-- prettier-ignore-end -->
Before this release, the env-to-ini prefix was `ENV_TO_INI__`.
This allowed a clear distinction between user-provided and chart-provided env-to-ini variables.
Due to the removal custom prefix feature in the upstream implementation of env-to-ini, the prefix has been changed to the default `GITEA__`.
If you previously had defined env vars that had the `ENV_TO_INI__` prefix, you need to change them to `GITEA__` in order for them to be picked up by the chart.
</details>
<details>
<summary>To 8.0.0</summary>
### Removal of MariaDB and MySQL DB chart dependencies <!-- omit from toc -->
In this version support for DB chart dependencies of MySQL and MariaDB have been removed to simplify the maintenance of the helm chart.
External MySQL and MariaDB databases are still supported and will be in the future.
### Postgres Update from v11 to v15 <!-- omit from toc -->
This Chart version updates the Postgres chart dependency and subsequently Postgres from v11 to v15.
Please read the [Postgres Release Notes](https://www.postgresql.org/docs/release/) for version-specific changes.
With respect to `values.yaml`, parameters `username`, `database` and `password` have been regrouped under `auth` and slightly renamed.
`persistence` has also been regrouped under the `primary` key.
Please adjust your `values.yaml` accordingly.
**Attention**: The Postgres upgrade is not automatically handled by the chart and must be done by yourself.
See [this comment](https://gitea.com/gitea/helm-chart/issues/452#issuecomment-740885) for an extensive walkthrough.
We again highly encourage users to use an external (managed) database for production instances.
</details>
<details>
<summary>To 7.0.0</summary>
### Private GPG key configuration for Gitea signing actions <!-- omit from toc -->
Having `signing.enabled=true` now requires to use either `signing.privateKey` or `signing.existingSecret` so that the Chart can automatically prepare the GPG key for Gitea internal signing actions.
See [Configure commit signing](#configure-commit-signing) for details.
</details>
<details>
<summary>To 6.0.0</summary>
### Different volume mounts for init-containers and runtime container <!-- omit from toc -->
**The `extraVolumeMounts` is deprecated** in favor of `extraInitVolumeMounts` and `extraContainerVolumeMounts`.
You can now have different mounts for the initialization phase and Gitea runtime.
The deprecated `extraVolumeMounts` will still be available for the time being and is mounted into every container.
If you want to switch to the new settings and want to mount specific volumes into all containers, you have to configure their mount points within both new settings.
**Combining values from the deprecated setting with values from the new settings is not possible.**
### New `enabled` flag for `startupProbe` <!-- omit from toc -->
Prior to this version the `startupProbe` was just a commented sample within the `values.yaml`.
With the migration to an auto-generated [Parameters](#parameters) section, a new parameter `gitea.startupProbe.enabled` has been introduced set to
`false` by default.
If you are using the `startupProbe` you need to add that new parameter and set it to `true`.
Otherwise, your defined probe won't be considered after the upgrade.
</details>
<details>
<summary>To 5.0.0</summary>
> 💥 The Helm Chart now requires Gitea versions of at least 1.11.0.
### Enable Dependencies <!-- omit from toc -->
The values to enable the dependencies, such as PostgreSQL, Memcached, MySQL and MariaDB have been moved from `gitea.database.builtIn.` to the dependency values.
You can now enable the dependencies as followed:
```yaml
memcached:
enabled: true
postgresql:
enabled: true
mysql:
enabled: false
mariadb:
enabled: false
```
### App.ini generation <!-- omit from toc -->
The app.ini generation has changed and now utilizes the environment-to-ini script provided by newer Gitea versions.
This change ensures, that the app.ini is now persistent.
### Secret Key generation <!-- omit from toc -->
Gitea secret keys (SECRET_KEY, INTERNAL_TOKEN, JWT_SECRET) are now generated automatically in certain situations:
- New install: By default the secrets are created automatically.
If you provide secrets via `gitea.config` they will be used instead of automatic generation.
- Existing installs: The secrets won't be deployed, neither via configuration nor via auto generation.
We explicitly prevent to set new secrets.
> 💡 It would be possible to set new secret keys manually by entering the running container and rewriting the app.ini by hand.
> However, this it is not advisable to do so for existing installations.
> Certain settings like _LDAP_ would not be readable anymore.
### Probes <!-- omit from toc -->
`gitea.customLivenessProbe`, `gitea.customReadinessProbe` and `gitea.customStartupProbe` have been removed.
They are replaced by the settings `gitea.livenessProbe`, `gitea.readinessProbe` and `gitea.startupProbe` which are now fully configurable and used _as-is_ for
a Chart deployment.
If you have customized their values instead of using the `custom` prefixed settings, please ensure that you remove the `enabled` property from each of them.
In case you want to disable one of these probes, let's say the `livenessProbe`, add the following to your values.
The `podAnnotation` is just there to have a bit more context.
```diff
gitea:
+ livenessProbe:
podAnnotations: {}
```
### Multiple OAuth and LDAP authentication sources <!-- omit from toc -->
With `5.0.0` of this Chart it is now possible to configure Gitea with multiple OAuth and LDAP sources.
As a result, you need to update an existing OAuth/LDAP configuration in your customized `values.yaml` by replacing the object with settings to a list
of settings objects.
See [OAuth2 Settings](#oauth2-settings) and [LDAP Settings](#ldap-settings) section for details.
</details>
<details>
<summary>To 4.0.0</summary>
### Ingress changes <!-- omit from toc -->
To provide a more flexible Ingress configuration we now support not only host settings but also provide configuration for the path and pathType.
So this change changes the hosts from a simple string list, to a list containing a more complex object for more configuration.
```diff
ingress:
enabled: false

### Dropped kebab-case support <!-- omit from toc -->
In 3.x.x it was possible to provide an ldap configuration via kebab-case, this support has now been dropped and only camel case is supported.
See [LDAP section](#ldap-settings) for more information.
### Dependency update <!-- omit from toc -->
The chart comes with multiple databases and Memcached as dependency, the latest release updated the dependencies.
- Memcached: `4.2.20` -> `5.9.0`
- PostgreSQL: `9.7.2` -> `10.3.17`
- MariaDB: `8.0.0` -> `9.3.6`
If you're using the builtin databases you will most likely redeploy the chart in order to update the database correctly.
### Execution of initPreScript <!-- omit from toc -->
Generally spoken, this might not be a breaking change, but it is worth to be mentioned.
Prior to `4.0.0` only one init container was used to both setup directories and configure Gitea.
As of now the actual Gitea configuration is separated from the other pre-execution.
This also includes the execution of _initPreScript_.
If you have such script, please be aware of this.
Dynamically prepare the Gitea setup during execution by e.g. adding environment variables to the execution context won't work anymore.
### Gitea Version 1.14.X repository ROOT <!-- omit from toc -->
Previously the ROOT folder for the Gitea repositories was located at `/data/git/gitea-repositories`.
In version `1.14` has the path been changed to `/data/gitea-repositories`.
This chart will set the `gitea.config.repository.ROOT` value default to `/data/git/gitea-repositories`.
