Gitea Helm Chart

Gitea is a community managed lightweight code hosting solution written in Go. It is published under the MIT license.

Readme will be updated with examples in the next few days

Introduction

This helm chart has taken some inspiration from https://github.com/jfelten/gitea-helm-chart But takes a completly different approach in providing database and cache with dependencies. Also this chart provides ldap and admin user configuration with values as well as it is deployed as statefulset to retain stored repositories.

Dependencies

Gitea can be run with external database and cache. This chart provides those dependencies, which can be enabled, or disabled via configuration.

Dependencies:

• Postgresql
• Memcached
• Mysql

Installing

  helm repo add novum-rgi-helm https://novumrgi.github.io/helm/
  helm install gitea novum-rgi-helm/gitea

Prerequisites

• Kubernetes 1.12+
• Helm 3.0+
• PV provisioner for persistent data support

Examples

Gitea Configuration

Gitea offers lots of configuration. 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]:"

Ports and external url

By default port 3000 is used for web traffic and 22 for ssh. Those can be changed:

  service:
    http: 
      port: 3000
    ssh:
      port: 22

This helmchart 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.

Cache

This helm chart can use a built in cache. The default is memcached from bitnami.

  gitea:
    cache:
      builtIn:
        enabled: true

If the built in cache should not be used simply configure the cache in gitea.config

  gitea:
    config:
      cache:
        ENABLED: true
        ADAPTER: memory
        INTERVAL: 60
        HOST: 127.0.0.1:9090

Persistence

Gitea will be deployed as a statefulset. 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 statefulset. This PVC will not be deleted even if you uninstall the chart. When using Postgresql as dependency, this will also be deployed as a statefulset by default.

If you want to manage your own PVC you can simply pass the PVC name to the chart.

  persistence:
    enabled: true
    existingClaim: MyAwesomeGiteaClaim

In case that peristence 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:

  postgresql:
    persistence:
      enabled: true
      existingClaim: MyAwesomeGiteaPostgresClaim

Mysql also handles persistence the same, even though it is not deployed as a statefulset. You can interact with the postgres settings as displayed in the following example:

  mysql:
    persistence:
      enabled: true
      existingClaim: MyAwesomeGiteaMysqlClaim

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 redeloying the chart. It is not possible to delete an admin user after it has been created. This has to be done in the ui.

  gitea:
    admin:
      username: "MyAwesomeGiteaAdmin"
      password: "AReallyAwesomeGiteaPassword"
      email: "gi@tea.com"

LDAP Settings

Like the admin user the ldap settings can be updated but also disabled or deleted.

  gitea:
    ldap:
      enabled: true
      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
