rancher/aks-operator

AKS operator is a Kubernetes CRD controller that controls cluster provisioning in Azure Kubernetes Service using an AKSClusterConfig defined by a Custom Resource Definition.

Build

Operator binary can be built using the following command:

    make operator

Deploy operator from source

You can use the following command to deploy a Kind cluster with Rancher manager and operator:

    make kind-deploy-operator

After this, you can also downscale operator deployment and run operator from a local binary.

Tests

Running unit tests can be done using the following command:

    make test

E2E

We run e2e tests after every merged PR and periodically every 24 hours. They are triggered by a Github action

For running e2e set the following variables and run:

    export AZURE_CLIENT_ID="replace_with_your_client_id"
    export AZURE_CLIENT_SECRET="replace_with_client_secret"
    export AZURE_SUBSCRIPTION_ID="replace_with_subscription_id"
    make kind-e2e-tests

A Kind cluster will be created, and the e2e tests will be run against it.

To delete the local Kind cluster once e2e tests are completed, run:

    make delete-local-kind-cluster

Release

When should I release?

A KEv2 operator should be released if

• There have been several commits since the last release,
• You need to pull in an update/bug fix/backend code to unblock UI for a feature enhancement in Rancher
• The operator needs to be unRC for a Rancher release

How do I release?

Tag the latest commit on the master branch. For example, if latest tag is:

• v1.0.8-rc1 you should tag v1.0.8-rc2.
• v1.0.8 you should tag v1.0.9-rc1.

# Get the latest upstream changes
# Note: `upstream` must be the remote pointing to `[email protected]:rancher/aks-operator.git`.
git pull upstream master --tags

# Export the tag of the release to be cut, e.g.:
export RELEASE_TAG=v1.0.8-rc2

# Create tags locally
git tag -s -a ${RELEASE_TAG} -m ${RELEASE_TAG}

# Push tags
# Note: `upstream` must be the remote pointing to `[email protected]:rancher/aks-operator.git`.
git push upstream ${RELEASE_TAG}

After pushing the release tag, you need to run 2 Github actions. You can find them in the Actions tab of the repo:

• Update AKS operator in rancher/rancher - This action will update the AKS operator in rancher/rancher repo. It will bump go dependencies.
• Update AKS Operator in rancher/charts - This action will update the AKS operator in rancher/charts repo. It will bump the chart version.

How do I unRC?

UnRC is the process of removing the rc from a KEv2 operator tag and means the released version is stable and ready for use. Release the KEv2 operator but instead of bumping the rc, remove the rc. For example, if the latest release of AKS operator is:

• v1.0.8-rc1, release the next version without the rc which would be v1.0.8.
• v1.0.8, that has no rc so release that version or v1.0.9 if updates are available.
