[release-1.18] Update Helm release action to work on release branches
2020-07-23 11:19:26 -07:00
Mike Dame
78313651dc Update Helm release action to work on release branches
Basing this action on push to `chart-*` tags doesn't work: the action itself
creates the new release tag, so trying to push the changes to a tag ends up
with the releaser comparing the changes to themself (and failing).

This also renames the chart from "descheduler" to "descheduler-helm-chart", to
avoid confusion with automated releases.

d2b8f07876 Bump Helm chart to version 0.18.1
This still represents Descheduler v0.18.0, but this is to make a small change
in order to try triggering the Helm chart-releaser action.

This moves the kind setup (previously used by Travis) to the e2e runner script
to accomodate the switch to Prow. This provides a KIND_E2E env var to specify
whether to run the tests in kind, or (by default) to run locally).

# Descheduler Design Constraints
This is a slowly growing document that lists good practices, conventions, and design decisions.
## Overview
TBD
## Code convention
* *formatting code*: running `make fmt` before committing each change to avoid ci failing
## Unit Test Conventions
These are the known conventions that are useful to practice whenever reasonable:
* *single pod creation*: each pod variable built using `test.BuildTestPod` is updated only through the `apply` argument of `BuildTestPod`
* *single node creation*: each node variable built using `test.BuildTestNode` is updated only through the `apply` argument of `BuildTestNode`
* *no object instance sharing*: each object built through `test.BuildXXX` functions is newly created in each unit test to avoid accidental object mutations
* *no object instance duplication*: avoid duplication by no creating two objects with the same passed values at two different places. E.g. two nodes created with the same memory, cpu and pods requests. Rather create a single function wrapping test.BuildTestNode and invoke this wrapper multiple times.
The aim is to reduce cognitive load when reading and debugging the test code.
## Design Decisions FAQ
This section documents common questions about design decisions in the descheduler codebase and the rationale behind them.
### Why doesn't the framework provide helpers for registering and retrieving indexers for plugins?
In general, each plugin can have many indexers—for example, for nodes, namespaces, pods, and other resources. Each plugin, depending on its internal optimizations, may choose a different indexing function. Indexers are currently used very rarely in the framework and default plugins. Therefore, extending the framework interface with additional helpers for registering and retrieving indexers might introduce an unnecessary and overly restrictive layer without first understanding how indexers will be used. For the moment, I suggest avoiding any restrictions on how many indexers can be registered or which ones can be registered. Instead, we should extend the framework handle to provide a unique ID for each profile, so that indexers within the same profile share a unique prefix. This avoids collisions when the same profile is instantiated more than once. Later, once we learn more about indexer usage, we can revisit whether it makes sense to impose additional restrictions.

## Introduction
This chart bootstraps a [descheduler](https://github.com/kubernetes-sigs/descheduler/) cron job with a default DeschedulerPolicy on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager. To preview what changes descheduler would make without actually going forward with the changes, you can install descheduler in dry run mode by providing the flag `--set cmdOptions.dry-run=true` to the `helm install` command below.

## descheduler
descheduler
### Synopsis
The descheduler evicts pods which may be bound to less desired nodes
```
descheduler [flags]
```
### Options
```
--bind-address ip The IP address on which to listen for the --secure-port port. The associated interface(s) must be reachable by the rest of the cluster, and by CLI/web clients. If blank or an unspecified address (0.0.0.0 or ::), all interfaces and IP address families will be used. (default 0.0.0.0)
--cert-dir string The directory where the TLS certs are located. If --tls-cert-file and --tls-private-key-file are provided, this flag will be ignored. (default "apiserver.local.config/certificates")
--client-connection-burst int32 Burst to use for interacting with kubernetes apiserver.
--client-connection-kubeconfig string File path to kube configuration for interacting with kubernetes apiserver.
--client-connection-qps float32 QPS to use for interacting with kubernetes apiserver.
--descheduling-interval duration Time interval between two consecutive descheduler executions. Setting this value instructs the descheduler to run in a continuous loop at the interval specified.
--disable-http2-serving If true, HTTP2 serving will be disabled [default=false]
--disable-metrics Disables metrics. The metrics are by default served through https://localhost:10258/metrics. Secure address, resp. port can be changed through --bind-address, resp. --secure-port flags.
--dry-run Execute descheduler in dry run mode.
--enable-http2 If http/2 should be enabled for the metrics and health check
--feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
AllAlpha=true|false (ALPHA - default=false)
AllBeta=true|false (BETA - default=false)
EvictionsInBackground=true|false (ALPHA - default=false)
-h, --help help for descheduler
--http2-max-streams-per-connection int The limit that the server gives to clients for the maximum number of streams in an HTTP/2 connection. Zero means to use golang's default.
--kubeconfig string File with kube configuration. Deprecated, use client-connection-kubeconfig instead.
--leader-elect Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability.
--leader-elect-lease-duration duration The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled. (default 2m17s)
--leader-elect-renew-deadline duration The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than the lease duration. This is only applicable if leader election is enabled. (default 1m47s)
--leader-elect-resource-lock string The type of resource object that is used for locking during leader election. Supported options are 'leases'. (default "leases")
--leader-elect-resource-name string The name of resource object that is used for locking during leader election. (default "descheduler")
--leader-elect-resource-namespace string The namespace of resource object that is used for locking during leader election. (default "kube-system")
--leader-elect-retry-period duration The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 26s)
--log-flush-frequency duration Maximum number of seconds between log flushes (default 5s)
--log-json-info-buffer-size quantity [Alpha] In JSON format with split output streams, the info messages can be buffered for a while to increase performance. The default value of zero bytes disables buffering. The size can be specified as number of bytes (512), multiples of 1000 (1K), multiples of 1024 (2Ki), or powers of those (3M, 4G, 5Mi, 6Gi). Enable the LoggingAlphaOptions feature gate to use this.
--log-json-split-stream [Alpha] In JSON format, write error messages to stderr and info messages to stdout. The default is to write a single stream to stdout. Enable the LoggingAlphaOptions feature gate to use this.
--log-text-info-buffer-size quantity [Alpha] In text format with split output streams, the info messages can be buffered for a while to increase performance. The default value of zero bytes disables buffering. The size can be specified as number of bytes (512), multiples of 1000 (1K), multiples of 1024 (2Ki), or powers of those (3M, 4G, 5Mi, 6Gi). Enable the LoggingAlphaOptions feature gate to use this.
--log-text-split-stream [Alpha] In text format, write error messages to stderr and info messages to stdout. The default is to write a single stream to stdout. Enable the LoggingAlphaOptions feature gate to use this.
--logging-format string Sets the log format. Permitted formats: "json" (gated by LoggingBetaOptions), "text". (default "text")
--otel-collector-endpoint string Set this flag to the OpenTelemetry Collector Service Address
--otel-fallback-no-op-on-error Fallback to NoOp Tracer in case of error

--otel-trace-namespace string OTEL Trace namespace to be used with the resources
--otel-transport-ca-cert string Path of the CA Cert that can be used to generate the client Certificate for establishing secure connection to the OTEL in gRPC mode
--permit-address-sharing If true, SO_REUSEADDR will be used when binding the port. This allows binding to wildcard IPs like 0.0.0.0 and specific IPs in parallel, and it avoids waiting for the kernel to release sockets in TIME_WAIT state. [default=false]
--permit-port-sharing If true, SO_REUSEPORT will be used when binding the port, which allows more than one instance to bind on the same address and port. [default=false]
--policy-config-file string File with descheduler policy configuration.
--secure-port int The port on which to serve HTTPS with authentication and authorization. If 0, don't serve HTTPS at all. (default 10258)
--tls-cert-file string File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir.
--tls-cipher-suites strings Comma-separated list of cipher suites for the server. If omitted, the default Go cipher suites will be used.
Preferred values: TLS_AES_128_GCM_SHA256, TLS_AES_256_GCM_SHA384, TLS_CHACHA20_POLY1305_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256.
Insecure values: TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_RC4_128_SHA.
--tls-min-version string Minimum TLS version supported. Possible values: VersionTLS10, VersionTLS11, VersionTLS12, VersionTLS13
--tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.
--tls-sni-cert-key namedCertKey A pair of x509 certificate and private key file paths, optionally suffixed with a list of domain patterns which are fully qualified domain names, possibly with prefixed wildcard segments. The domain patterns also allow IP addresses, but IPs should only be used if the apiserver has visibility to the IP address requested by a client. If no domain patterns are provided, the names of the certificate are extracted. Non-wildcard matches trump over wildcard matches, explicit domain patterns trump over extracted names. For multiple key/certificate pairs, use the --tls-sni-cert-key multiple times. Examples: "example.crt,example.key" or "foo.crt,foo.key:*.foo.com,foo.com". (default [])
-v, --v Level number for the log level verbosity
--vmodule pattern=N,... comma-separated list of pattern=N settings for file-filtered logging (only works for text log format)

# Release Guide
The process for publishing each Descheduler release includes a mixture of manual and automatic steps. Over
time, it would be good to automate as much of this process as possible. However, due to current limitations there
is care that must be taken to perform each manual step precisely so that the automated steps execute properly.
## Container Image
## Pre-release Code Changes
### Semi-automatic
Before publishing each release, the following code updates must be made:
1. Make sure your repo is clean by git's standards
2. Create a release branch `git checkout -b release-1.18` (not required for patch releases)
3. Push the release branch to the descheuler repo and ensure branch protection is enabled (not required for patch releases)
4. Tag the repository from the `master` branch (from the `release-1.18` branch for a patch release) and push the tag `VERSION=v0.18.0 git tag -m $VERSION $VERSION; git push origin $VERSION`
5. Publish a draft release using the tag you just created
6. Perform the [image promotion process](https://github.com/kubernetes/k8s.io/tree/master/k8s.gcr.io#image-promoter)
7. Publish release
8. Email `kubernetes-sig-scheduling@googlegroups.com` to announce the release
- [ ] (Optional, but recommended) Bump `k8s.io` dependencies to the `-rc` tags. These tags are usually published around upstream code freeze. [Example](https://github.com/kubernetes-sigs/descheduler/pull/539)
- [ ] Bump `k8s.io` dependencies to GA tags once they are published (following the upstream release). [Example](https://github.com/kubernetes-sigs/descheduler/pull/615)
- [ ] Ensure that Go is updated to the same version as upstream. [Example](https://github.com/kubernetes-sigs/descheduler/pull/801)
- [ ] Make CI changes in [github.com/kubernetes/test-infra](https://github.com/kubernetes/test-infra) to add the new version's tests (note, this may also include a Go bump). [Example](https://github.com/kubernetes/test-infra/pull/25833)
- [ ] Update local CI versions for utils (such as golang-ci), kind, and go. [Example - e2e](https://github.com/kubernetes-sigs/descheduler/commit/ac4d576df8831c0c399ee8fff1e85469e90b8c44), [Example - helm](https://github.com/kubernetes-sigs/descheduler/pull/821)
- [ ] Update version references in docs and Readme. [Example](https://github.com/kubernetes-sigs/descheduler/pull/617)
### Manual
## Release Process
1. Make sure your repo is clean by git's standards
2. Create a release branch `git checkout -b release-1.18` (not required for patch releases)
3. Push the release branch to the descheuler repo and ensure branch protection is enabled (not required for patch releases)
4. Tag the repository from the `master` branch (from the `release-1.18` branch for a patch release) and push the tag `VERSION=v0.18.0 git tag -m $VERSION $VERSION; git push origin $VERSION`
5. Checkout the tag you just created and make sure your repo is clean by git's standards `git checkout $VERSION`
6. Build and push the container image to the staging registry `VERSION=$VERSION make push`
7. Publish a draft release using the tag you just created
8. Perform the [image promotion process](https://github.com/kubernetes/k8s.io/tree/master/k8s.gcr.io#image-promoter)
9. Publish release
10. Email `kubernetes-sig-scheduling@googlegroups.com` to announce the release
When the above pre-release steps are complete and the release is ready to be cut, perform the following steps **in order**
(the flowchart below demonstrates these steps):
**Version release**
1. Create the `git tag` on `master` for the release, eg `v0.24.0`
2. Merge Helm chart version update to `master` (see [Helm chart](#helm-chart) below). [Example](https://github.com/kubernetes-sigs/descheduler/pull/709)
3. Perform the [image promotion process](https://github.com/kubernetes/k8s.io/tree/main/k8s.gcr.io#image-promoter). [Example](https://github.com/kubernetes/k8s.io/pull/3344)
4. Cut release branch from `master`, eg `release-1.24`
5. Publish release using Github's release process from the git tag you created
6. Email `sig-scheduling@kubernetes.io` to announce the release
**Patch release**
1. Pick relevant code change commits to the matching release branch, eg `release-1.24`
2. Create the patch tag on the release branch, eg `v0.24.1` on `release-1.24`
3. Merge Helm chart version update to release branch
4. Perform the image promotion process for the patch version
5. Publish release using Github's release process from the git tag you created
6. Email `sig-scheduling@kubernetes.io` to announce the release
### Flowchart
![Flowchart for major and patch releases](release-process.png)
### Image promotion process
Every merge to any branch triggers an [image build and push](https://github.com/kubernetes/test-infra/blob/c36b8e5/config/jobs/image-pushing/k8s-staging-descheduler.yaml) to a `gcr.io` repository.
These automated image builds are snapshots of the code in place at the time of every PR merge and
tagged with the latest git SHA at the time of the build. To create a final release image, the desired
auto-built image SHA is added to a [file upstream](https://github.com/kubernetes/k8s.io/blob/e9e971c/k8s.gcr.io/images/k8s-staging-descheduler/images.yaml) which
copies that image to a public registry.
Automatic builds can be monitored and re-triggered with the [`post-descheduler-push-images` job](https://prow.k8s.io/?job=post-descheduler-push-images) on prow.k8s.io.
Note that images can also be manually built and pushed using `VERSION=$VERSION make push-all` by [users with access](https://github.com/kubernetes/k8s.io/blob/fbee8f67b70304241e613a672c625ad972998ad7/groups/sig-scheduling/groups.yaml#L33-L43).
## Helm Chart
We currently use the [chart-releaser-action GitHub Action](https://github.com/helm/chart-releaser-action) to automatically
publish [Helm chart releases](https://github.com/kubernetes-sigs/descheduler/blob/022e07c/.github/workflows/release.yaml).
This action is triggered when it detects any changes to [`Chart.yaml`](https://github.com/kubernetes-sigs/descheduler/blob/022e07c27853fade6d1304adc0a6ebe02642386c/charts/descheduler/Chart.yaml) on
a `release-*` branch.
Helm chart releases are managed by a separate set of git tags that are prefixed with `descheduler-helm-chart-*`. Example git tag name is `descheduler-helm-chart-0.18.0`.
Released versions of the helm charts are stored in the `gh-pages` branch of this repo.
The major and minor version of the chart matches the descheduler major and minor versions. For example descheduler helm chart version helm-descheduler-chart-0.18.0 corresponds
to descheduler version v0.18.0. The patch version of the descheduler helm chart and the patcher version of the descheduler will not necessarily match. The patch
version of the descheduler helm chart is used to version changes specific to the helm chart.
1. Merge all helm chart changes into the master branch before the release is tagged/cut
1. Ensure that `appVersion` in file `charts/descheduler/Chart.yaml` matches the descheduler version(no `v` prefix)
2. Ensure that `version` in file `charts/descheduler/Chart.yaml` has been incremented. This is the chart version.
2. Make sure your repo is clean by git's standards
3. Follow the release-branch or patch release tagging pattern from the above section.
4. Verify the new helm artifact has been successfully pushed to the `gh-pages` branch
## Notes
The Helm releaser-action compares the changes in the action-triggering branch to the latest tag on that branch, so if you tag before creating the new branch there
will be nothing to compare and it will fail. This is why it's necessary to tag, eg, `v0.24.0` *before* making the changes to the
Helm chart version, so that there is a new diff for the action to find. (Tagging *after* making the Helm chart changes would
also work, but then the code that gets built into the promoted image will be tagged as `descheduler-helm-chart-xxx` rather than `v0.xx.0`).
### Notes
It's important to create the tag on the master branch after creating the release-* branch so that the [Helm releaser-action](#helm-chart) can work.
It compares the changes in the action-triggering branch to the latest tag on that branch, so if you tag before creating the new branch there
will be nothing to compare and it will fail (creating a new release branch usually involves no code changes). For this same reason, you should
also tag patch releases (on the release-* branch) *after* pushing changes (if those changes involve bumping the Helm chart version).

### Balance Cluster By Node Memory Utilization
If your cluster has been running for a long period of time, you may find that the resource utilization is not very
balanced. The following two strategies can be used to rebalance your cluster based on `cpu`, `memory`
or `number of pods`.
#### Balance high utilization nodes
Using `LowNodeUtilization`, descheduler will rebalance the cluster based on memory by evicting pods
from nodes with memory utilization over 70% to nodes with memory utilization below 20%.
```
apiVersion: "descheduler/v1alpha2"
kind: "DeschedulerPolicy"
profiles:
- name: ProfileName
pluginConfig:
- name: "LowNodeUtilization"
args:
thresholds:
"memory": 20
targetThresholds:
"memory": 70
plugins:
balance:
enabled:
- "LowNodeUtilization"
```
#### Balance low utilization nodes
Using `HighNodeUtilization`, descheduler will rebalance the cluster based on memory by evicting pods
from nodes with memory utilization lower than 20%. This should be use `NodeResourcesFit` with the `MostAllocated` scoring strategy based on these [doc](https://kubernetes.io/docs/reference/scheduling/config/#scheduling-plugins).
The evicted pods will be compacted into minimal set of nodes.
```
apiVersion: "descheduler/v1alpha2"
kind: "DeschedulerPolicy"
profiles:
- name: ProfileName
pluginConfig:
- name: "HighNodeUtilization"
args:
thresholds:
"memory": 20
plugins:
balance:
enabled:
- "HighNodeUtilization"
```
### Autoheal Node Problems
Descheduler's `RemovePodsViolatingNodeTaints` strategy can be combined with
[Node Problem Detector](https://github.com/kubernetes/node-problem-detector/) and
[Cluster Autoscaler](https://github.com/kubernetes/autoscaler/tree/master/cluster-autoscaler) to automatically remove
Nodes which have problems. Node Problem Detector can detect specific Node problems and report them to the API server.
There is a feature called TaintNodeByCondition of the node controller that takes some conditions and turns them into taints. Currently, this only works for the default node conditions: PIDPressure, MemoryPressure, DiskPressure, Ready, and some cloud provider specific conditions.
The Descheduler will then deschedule workloads from those Nodes. Finally, if the descheduled Node's resource
allocation falls below the Cluster Autoscaler's scale down threshold, the Node will become a scale down candidate
and can be removed by Cluster Autoscaler. These three components form an autohealing cycle for Node problems.

**NOTE**
Once [kubernetes/node-problem-detector#565](https://github.com/kubernetes/node-problem-detector/pull/565) is available in NPD, we need to update this section.
