# Contributor Covenant Code of Conduct
|
||||||
|
|
||||||
|
## Our Pledge
|
||||||
|
|
||||||
|
In the interest of fostering an open and welcoming environment, we as
|
||||||
|
contributors and maintainers pledge to making participation in our project and
|
||||||
|
our community a harassment-free experience for everyone, regardless of age, body
|
||||||
|
size, disability, ethnicity, gender identity and expression, level of experience,
|
||||||
|
nationality, personal appearance, race, religion, or sexual identity and
|
||||||
|
orientation.
|
||||||
|
|
||||||
|
## Our Standards
|
||||||
|
|
||||||
|
Examples of behavior that contributes to creating a positive environment
|
||||||
|
include:
|
||||||
|
|
||||||
|
* Using welcoming and inclusive language
|
||||||
|
* Being respectful of differing viewpoints and experiences
|
||||||
|
* Gracefully accepting constructive criticism
|
||||||
|
* Focusing on what is best for the community
|
||||||
|
* Showing empathy towards other community members
|
||||||
|
|
||||||
|
Examples of unacceptable behavior by participants include:
|
||||||
|
|
||||||
|
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||||
|
advances
|
||||||
|
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||||
|
* Public or private harassment
|
||||||
|
* Publishing others' private information, such as a physical or electronic
|
||||||
|
address, without explicit permission
|
||||||
|
* Other conduct which could reasonably be considered inappropriate in a
|
||||||
|
professional setting
|
||||||
|
|
||||||
|
## Our Responsibilities
|
||||||
|
|
||||||
|
Project maintainers are responsible for clarifying the standards of acceptable
|
||||||
|
behavior and are expected to take appropriate and fair corrective action in
|
||||||
|
response to any instances of unacceptable behavior.
|
||||||
|
|
||||||
|
Project maintainers have the right and responsibility to remove, edit, or
|
||||||
|
reject comments, commits, code, wiki edits, issues, and other contributions
|
||||||
|
that are not aligned to this Code of Conduct, or to ban temporarily or
|
||||||
|
permanently any contributor for other behaviors that they deem inappropriate,
|
||||||
|
threatening, offensive, or harmful.
|
||||||
|
|
||||||
|
## Scope
|
||||||
|
|
||||||
|
This Code of Conduct applies both within project spaces and in public spaces
|
||||||
|
when an individual is representing the project or its community. Examples of
|
||||||
|
representing a project or community include using an official project e-mail
|
||||||
|
address, posting via an official social media account, or acting as an appointed
|
||||||
|
representative at an online or offline event. Representation of a project may be
|
||||||
|
further defined and clarified by project maintainers.
|
||||||
|
|
||||||
|
## Enforcement
|
||||||
|
|
||||||
|
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||||
|
reported by contacting the project team see [MAINTAINERS.md](MAINTAINERS.md). All
|
||||||
|
complaints will be reviewed and investigated and will result in a response that
|
||||||
|
is deemed necessary and appropriate to the circumstances. The project team is
|
||||||
|
obligated to maintain confidentiality with regard to the reporter of an incident.
|
||||||
|
Further details of specific enforcement policies may be posted separately.
|
||||||
|
|
||||||
|
Project maintainers who do not follow or enforce the Code of Conduct in good
|
||||||
|
faith may face temporary or permanent repercussions as determined by other
|
||||||
|
members of the project's leadership.
|
||||||
|
|
||||||
|
## Attribution
|
||||||
|
|
||||||
|
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
|
||||||
|
available at [http://contributor-covenant.org/version/1/4][version]

# Contributing
|
||||||
|
|
||||||
|
**Thank you for your interest in making the project better and more useful.
|
||||||
|
Your contributions are highly welcome.**
|
||||||
|
|
||||||
|
There are multiple ways of getting involved:
|
||||||
|
|
||||||
|
- [Report a bug](#report-a-bug)
|
||||||
|
- [Suggest a feature](#suggest-a-feature)
|
||||||
|
- [Contribute code](#contribute-code)
|
||||||
|
|
||||||
|
Below are a few guidelines we would like you to follow.
|
||||||
|
If you need help, please reach out to us by opening an issue.
|
||||||
|
|
||||||
|
## Report a bug
|
||||||
|
|
||||||
|
Reporting bugs is one of the best ways to contribute. Before creating a bug
|
||||||
|
report, please check that an [issue](/issues) reporting the same problem does
|
||||||
|
not already exist. If there is such an issue, you may add your information as a
|
||||||
|
comment.
|
||||||
|
|
||||||
|
To report a new bug you should open an issue that summarizes the bug and set
|
||||||
|
the label to "bug".
|
||||||
|
|
||||||
|
If you want to provide a fix along with your bug report: That is great! In this
|
||||||
|
case please send us a pull request as described in section [Contribute
|
||||||
|
Code](#contribute-code).
|
||||||
|
|
||||||
|
## Suggest a feature
|
||||||
|
|
||||||
|
To request a new feature you should open an [issue](../../issues/new) and
|
||||||
|
summarize the desired functionality and its use case. Set the issue label to
|
||||||
|
"feature".
|
||||||
|
|
||||||
|
## Contribute code
|
||||||
|
|
||||||
|
This is an outline of what the workflow for code contributions looks like
|
||||||
|
|
||||||
|
- Check the list of open [issues](../../issues). Either assign an existing
|
||||||
|
issue to yourself, or create a new one that you would like work on and
|
||||||
|
discuss your ideas and use cases.
|
||||||
|
|
||||||
|
It is always best to discuss your plans beforehand, to ensure that your
|
||||||
|
contribution is in line with our goals.
|
||||||
|
|
||||||
|
- Fork the repository on GitHub
|
||||||
|
- Create a topic branch from where you want to base your work. This is usually master.
|
||||||
|
- Open a new pull request, label it `work in progress` and outline what you will be contributing
|
||||||
|
- Make commits of logical units.
|
||||||
|
- Make sure you sign-off on your commits `git commit -s -m "adding X to change Y"`
|
||||||
|
- Write good commit messages (see below).
|
||||||
|
- Push your changes to a topic branch in your fork of the repository.
|
||||||
|
- As you push your changes, update the pull request with new infomation and tasks as you complete them
|
||||||
|
- Project maintainers might comment on your work as you progress
|
||||||
|
- When you are done, remove the `work in progess` label and ping the maintainers for a review
|
||||||
|
- Your pull request must receive a :thumbsup: from two [maintainers](MAINTAINERS)
|
||||||
|
|
||||||
|
Thanks for your contributions!
|
||||||
|
|
||||||
|
### Commit messages
|
||||||
|
|
||||||
|
Your commit messages ideally can answer two questions: what changed and why.
|
||||||
|
The subject line should feature the “what” and the body of the commit should
|
||||||
|
describe the “why”.
|
||||||
|
|
||||||
|
When creating a pull request, its description should reference the corresponding issue id.
|
||||||
|
|
||||||
|
### Sign your work / Developer certificate of origin
|
||||||
|
All contributions (including pull requests) must agree to the Developer
|
||||||
|
Certificate of Origin (DCO) version 1.1. This is exactly the same one created
|
||||||
|
and used by the Linux kernel developers and posted on
|
||||||
|
http://developercertificate.org/. This is a developer's certification that he
|
||||||
|
or she has the right to submit the patch for inclusion into the project. Simply
|
||||||
|
submitting a contribution implies this agreement, however, please include a
|
||||||
|
"Signed-off-by" tag in every patch (this tag is a conventional way to confirm
|
||||||
|
that you agree to the DCO) - you can automate this with a [Git
|
||||||
|
hook](https://stackoverflow.com/questions/15015894/git-add-signed-off-by-line-using-format-signoff-not-working)
|
||||||
|
|
||||||
|
```
|
||||||
|
git commit -s -m "adding X to change Y"
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
**Have fun, and happy hacking!**

General purpose metrics adapter for Kubernetes HPA metrics
|
[](https://travis-ci.com/mikkeloscar/kube-metrics-adapter)
|
||||||
|
|
||||||
|
Kube Metrics Adapter is a general purpose metrics adapter for Kubernetes that
|
||||||
|
can collect and serve custom and external metrics for Horizontal Pod
|
||||||
|
Autoscaling.
|
||||||
|
|
||||||
|
It discovers Horizontal Pod Autoscaling resources and starts to collect the
|
||||||
|
requested metrics and stores them in memory. It's implemented using the
|
||||||
|
[custom-metrics-apiserver](https://github.com/kubernetes-incubator/custom-metrics-apiserver)
|
||||||
|
library.
|
||||||
|
|
||||||
|
Here's an example of a `HorizontalPodAutoscaler` resource configured to get
|
||||||
|
`requests-per-second` metrics from each pod of the deployment `myapp`.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: autoscaling/v2beta1
|
||||||
|
kind: HorizontalPodAutoscaler
|
||||||
|
metadata:
|
||||||
|
name: myapp-hpa
|
||||||
|
annotations:
|
||||||
|
# metric-config.<metricType>.<metricName>.<collectorName>/<configKey>
|
||||||
|
metric-config.pods.requests-per-second.json-path/json-key: "$.http_server.rps"
|
||||||
|
metric-config.pods.requests-per-second.json-path/path: /metrics
|
||||||
|
metric-config.pods.requests-per-second.json-path/port: "9090"
|
||||||
|
spec:
|
||||||
|
scaleTargetRef:
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
name: myapp
|
||||||
|
minReplicas: 1
|
||||||
|
maxReplicas: 10
|
||||||
|
metrics:
|
||||||
|
- type: Pods
|
||||||
|
pods:
|
||||||
|
metricName: requests-per-second
|
||||||
|
targetAverageValue: 1k
|
||||||
|
```
|
||||||
|
|
||||||
|
The `metric-config.*` annotations are used by the `kube-metrics-adapter` to
|
||||||
|
configure a collector for getting the metrics. In the above example it
|
||||||
|
configures a *json-path pod collector*.
|
||||||
|
|
||||||
|
## Building
|
||||||
|
|
||||||
|
This project uses [Go modules](https://github.com/golang/go/wiki/Modules) as
|
||||||
|
introduced in Go 1.11 therefore you need Go >=1.11 installed in order to build.
|
||||||
|
If using Go 1.11 you also need to [activate Module
|
||||||
|
support](https://github.com/golang/go/wiki/Modules#installing-and-activating-module-support).
|
||||||
|
|
||||||
|
Assuming Go has been setup with module support it can be built simply by running:
|
||||||
|
|
||||||
|
```sh
|
||||||
|

||||||
|
## Collectors
|
||||||
|
|
||||||
|
Collectors are different implementations for getting metrics requested by an
|
||||||
|
HPA resource. They are configured based on HPA resources and started on-demand by the
|
||||||
|
`kube-metrics-adapter` to only collect the metrics required for scaling the application.
|
||||||
|
|
||||||
|
The collectors are configured either simply based on the metrics defined in an
|
||||||
|
HPA resource, or via additional annotations on the HPA resource.
|
||||||
|
|
||||||
|
## Pod collector
|
||||||
|
|
||||||
|
The pod collector allows collecting metrics from each pod matched by the HPA.
|
||||||
|
Currently only `json-path` collection is supported.
|
||||||
|
|
||||||
|
### Supported metrics
|
||||||
|
|
||||||
|
| Metric | Description | Type |
|
||||||
|
| ------------ | -------------- | ------- |
|
||||||
|
| *custom* | No predefined metrics. Metrics are generated from user defined queries. | Pods |
|
||||||
|
|
||||||
|
### Example
|
||||||
|
|
||||||
|
This is an example of using the pod collector to collect metrics from a json
|
||||||
|
metrics endpoint of each pod matched by the HPA.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: autoscaling/v2beta1
|
||||||
|
kind: HorizontalPodAutoscaler
|
||||||
|
metadata:
|
||||||
|
name: myapp-hpa
|
||||||
|
annotations:
|
||||||
|
# metric-config.<metricType>.<metricName>.<collectorName>/<configKey>
|
||||||
|
metric-config.pods.requests-per-second.json-path/json-key: "$.http_server.rps"
|
||||||
|
metric-config.pods.requests-per-second.json-path/path: /metrics
|
||||||
|
metric-config.pods.requests-per-second.json-path/port: "9090"
|
||||||
|
spec:
|
||||||
|
scaleTargetRef:
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
name: myapp
|
||||||
|
minReplicas: 1
|
||||||
|
maxReplicas: 10
|
||||||
|
metrics:
|
||||||
|
- type: Pods
|
||||||
|
pods:
|
||||||
|
metricName: requests-per-second
|
||||||
|
targetAverageValue: 1k
|
||||||
|
```
|
||||||
|
|
||||||
|
The pod collector is configured through the annotations which specify the
|
||||||
|
collector name `json-path` and a set of configuration options for the
|
||||||
|
collector. `json-key` defines the json-path query for extracting the right
|
||||||
|
metric. This assumes the pod is exposing metrics in JSON format. For the above
|
||||||
|
example the following JSON data would be expected:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"http_server": {
|
||||||
|
"rps": 0.5
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
The json-path query support depends on the
|
||||||
|
[github.com/oliveagle/jsonpath](https://github.com/oliveagle/jsonpath) library.
|
||||||
|
See the README for possible queries. It's expected that the metric you query
|
||||||
|
returns something that can be turned into a `float64`.
|
||||||
|
|
||||||
|
The other configuration options `path` and `port` specifies where the metrics
|
||||||
|
endpoint is exposed on the pod. There's no default values, so they must be
|
||||||
|
defined.
|
||||||
|
|
||||||
|
## Prometheus collector
|
||||||
|
|
||||||
|
The Prometheus collector is a generic collector which can map Prometheus
|
||||||
|
queries to metrics that can be used for scaling. This approach is different
|
||||||
|
from how it's done in the
|
||||||
|
[k8s-prometheus-adapter](https://github.com/DirectXMan12/k8s-prometheus-adapter)
|
||||||
|
where all available Prometheus metrics are collected
|
||||||
|
and transformed into metrics which the HPA can scale on, and there is no
|
||||||
|
possibility to do custom queries.
|
||||||
|
With the approach implemented here, users can define custom queries and only metrics
|
||||||
|
returned from those queries will be available, reducing the total number of
|
||||||
|
metrics stored.
|
||||||
|
|
||||||
|
One downside of this approach is that bad performing queries can slow down/kill
|
||||||
|
Prometheus, so it can be dangerous to allow in a multi tenant cluster. It's
|
||||||
|
also not possible to restrict the available metrics using something like RBAC
|
||||||
|
since any user would be able to create the metrics based on a custom query.
|
||||||
|
|
||||||
|
I still believe custom queries are more useful, but it's good to be aware of
|
||||||
|
the trade-offs between the two approaches.
|
||||||
|
|
||||||
|
### Supported metrics
|
||||||
|
|
||||||
|
| Metric | Description | Type | Kind |
|
||||||
|
| ------------ | -------------- | ------- | -- |
|
||||||
|
| *custom* | No predefined metrics. Metrics are generated from user defined queries. | Object | *any* |
|
||||||
|
|
||||||
|
### Example
|
||||||
|
|
||||||
|
This is an example of an HPA configured to get metrics based on a Prometheus
|
||||||
|
query. The query is defined in the annotation
|
||||||
|
`metric-config.object.processed-events-per-second.prometheus/query` where
|
||||||
|
`processed-events-per-second` is the metric name which will be associated with
|
||||||
|
the result of the query.
|
||||||
|
|
||||||
|
It also specifies an annotation
|
||||||
|
`metric-config.object.processed-events-per-second.prometheus/per-replica` which
|
||||||
|
instructs the collector to treat the results as an average over all pods
|
||||||
|
targeted by the HPA. This makes it possible to mimic the behavior of
|
||||||
|
`targetAverageValue` which is not implemented for metric type `Object` as of
|
||||||
|
Kubernetes v1.10. ([It will most likely come in v1.12](https://github.com/kubernetes/kubernetes/pull/64097#event-1696222479)).
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: autoscaling/v2beta1
|
||||||
|
kind: HorizontalPodAutoscaler
|
||||||
|
metadata:
|
||||||
|
name: myapp-hpa
|
||||||
|
annotations:
|
||||||
|
# metric-config.<metricType>.<metricName>.<collectorName>/<configKey>
|
||||||
|
metric-config.object.processed-events-per-second.prometheus/query: |
|
||||||
|
scalar(sum(rate(event-service_events_count{application="event-service",processed="true"}[1m])))
|
||||||
|
metric-config.object.processed-events-per-second.prometheus/per-replica: "true"
|
||||||
|
spec:
|
||||||
|
scaleTargetRef:
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
name: custom-metrics-consumer
|
||||||
|
minReplicas: 1
|
||||||
|
maxReplicas: 10
|
||||||
|
metrics:
|
||||||
|
- type: Object
|
||||||
|
object:
|
||||||
|
metricName: processed-events-per-second
|
||||||
|
target:
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Service
|
||||||
|
name: event-service
|
||||||
|
targetValue: 10 # this will be treated as targetAverageValue
|
||||||
|
```
|
||||||
|
|
||||||
|
## Skipper collector
|
||||||
|
|
||||||
|
The skipper collector is a simple wrapper around the Prometheus collector to
|
||||||
|
make it easy to define an HPA for scaling based on ingress metrics when
|
||||||
|
[skipper](https://github.com/zalando/skipper) is used as the ingress
|
||||||
|
implementation in your cluster. It assumes you are collecting Prometheus
|
||||||
|
metrics from skipper and it provides the correct Prometheus queries out of the
|
||||||
|
box so users don't have to define those manually.
|
||||||
|
|
||||||
|
### Supported metrics
|
||||||
|
|
||||||
|
| Metric | Description | Type | Kind |
|
||||||
|
| ----------- | -------------- | ------ | ---- |
|
||||||
|
| `requests-per-second` | Scale based on requests per second for a certain ingress. | Object | `Ingress` |
|
||||||
|
|
||||||
|
### Example
|
||||||
|
|
||||||
|
This is an example of an HPA that will scale based on `requests-per-second` for
|
||||||
|
an ingress called `myapp`.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: autoscaling/v2beta1
|
||||||
|
kind: HorizontalPodAutoscaler
|
||||||
|
metadata:
|
||||||
|
name: myapp-hpa
|
||||||
|
spec:
|
||||||
|
scaleTargetRef:
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
name: myapp
|
||||||
|
minReplicas: 1
|
||||||
|
maxReplicas: 10
|
||||||
|
metrics:
|
||||||
|
- type: Object
|
||||||
|
object:
|
||||||
|
metricName: requests-per-second
|
||||||
|
target:
|
||||||
|
apiVersion: extensions/v1beta1
|
||||||
|
kind: Ingress
|
||||||
|
name: myapp
|
||||||
|
targetValue: 10 # this will be treated as targetAverageValue
|
||||||
|
```
|
||||||
|
|
||||||
|
**Note:** As of Kubernetes v1.10 the HPA does not support `targetAverageValue` for
|
||||||
|
metrics of type `Object`. In case of requests per second it does not make sense
|
||||||
|
to scale on a summed value because you can not make the total requests per
|
||||||
|
second go down by adding more pods. For this reason the skipper collector will
|
||||||
|
automatically treat the value you define in `targetValue` as an average per pod
|
||||||
|
instead of a total sum.
|
||||||
|
|
||||||
|
## AWS collector
|
||||||
|
|
||||||
|
The AWS collector allows scaling based on external metrics exposed by AWS
|
||||||
|
services e.g. SQS queue lengths.
|
||||||
|
|
||||||
|
### Supported metrics
|
||||||
|
|
||||||
|
| Metric | Description | Type |
|
||||||
|
| ------------ | ------- | -- |
|
||||||
|
| `sqs-queue-length` | Scale based on SQS queue length | External |
|
||||||
|
|
||||||
|
### Example
|
||||||
|
|
||||||
|
This is an example of an HPA that will scale based on the length of an SQS
|
||||||
|
queue.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: autoscaling/v2beta1
|
||||||
|
kind: HorizontalPodAutoscaler
|
||||||
|
metadata:
|
||||||
|
name: myapp-hpa
|
||||||
|
spec:
|
||||||
|
scaleTargetRef:
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
name: custom-metrics-consumer
|
||||||
|
minReplicas: 1
|
||||||
|
maxReplicas: 10
|
||||||
|
metrics:
|
||||||
|
- type: External
|
||||||
|
external:
|
||||||
|
metricName: sqs-queue-length
|
||||||
|
metricSelector:
|
||||||
|
matchLabels:
|
||||||
|
queue-name: foobar
|
||||||
|
region: eu-central-1
|
||||||
|
targetAverageValue: 30
|
||||||
|
```
|
||||||
|
|
||||||
|
The `matchLabels` are used by `kube-metrics-adapter` to configure a collector
|
||||||
|
that will get the queue length for an SQS queue named `foobar` in region
|
||||||
|
`eu-central-1`.
|
||||||
|
|
||||||
|
The AWS account of the queue currently depends on how `kube-metrics-adapter` is
|
||||||
|
configured to get AWS credentials. The normal assumption is that you run the
|
||||||
|
adapter in a cluster running in the AWS account where the queue is defined.
|
||||||
|
