Actions & Workflows

Manual Trigger (workflow_dispatch)

It is currently not possible to run a workflow_dispatch based workflow on a specific branch, while it is not yet available in main branch, from the WebUI. If you would like to test your pipeline changes on a branch, use the GitHub CLI:

gh workflow run e2e-test-manual.yml \
    --ref feat/e2e_pipeline \                       # On your specific branch!
    -F autoscale=false -F cloudProvider=gcp \       # With your ...
    -F controlNodesCount=1 -F workerNodesCount=2 \  # ... settings
    -F machineType=n2d-standard-4

E2E Test Suites

Here are some examples for test suits you might want to run. Values for sonobuoyTestSuiteCmd:

--mode quick
- Runs a set of tests that are known to be quick to execute! (<1 min)
--e2e-focus "Services should be able to create a functioning NodePort service"
- Runs a specific test
--mode certified-conformance
- For K8s conformance certification test suite

Check Sonobuoy docs for more examples.

When using --mode be aware that --e2e-focus and e2e-skip will be overwritten. Check in the source code what the different modes do.

Local Development

Using nektos/act you can run GitHub actions locally.

Specific Jobs

act -j e2e-test-gcp

Simulate a `workflow_dispatch` event

Create a new JSON file to describe the event (relevant issue, there are no further information about structure of this file):

{
  "action": "workflow_dispatch",
  "inputs": {
      "workerNodesCount": "2",
      "controlNodesCount": "1",
      "autoscale": false,
      "cloudProvider": "gcp",
      "machineType": "n2d-standard-4",
      "sonobuoyTestSuiteCmd": "--mode quick"
  }
}

Then run act with the event as input:

act -j e2e-test-manual --eventpath event.json

Authorizing GCP

For creating Kubernetes clusters in GCP a local copy of the service account secret is required.

Create a new service account key
Create a compact (one line) JSON representation of the file jq -c
Store in GitHub Action Secret or create a local secret file for act to consume:

$ cat secrets.env
GCP_SERVICE_ACCOUNT={"type":"service_account", ... }

$ act --secret-file secrets.env

Authorizing Azure

Create a new service principal:

az ad sp create-for-rbac --name "github-actions-e2e-tests" --role contributor --scopes /subscriptions/0d202bbb-4fa7-4af8-8125-58c269a05435 --sdk-auth
az role assignment create --role "User Access Administrator" --scope /subscriptions/0d202bbb-4fa7-4af8-8125-58c269a05435 --assignee <SERVICE_PRINCIPAL_CLIENT_ID>

Next, add API permissions to Managed Identity:

Not possible through portal; requires PowerShell
https://techcommunity.microsoft.com/t5/integrations-on-azure-blog/grant-graph-api-permission-to-managed-identity-object/ba-p/2792127
$GraphAppId in this article is for Microsoft Graph. Azure AD Graph is 00000002-0000-0000-c000-000000000000
Note that changing permissions can take between few seconds to several hours

Store output of az ad sp ... in GitHub Action Secret or create a local secret file for act to consume.

Image versions

The build-coreos workflow can be used to trigger an image build.

The workflow can be used to build debug or release images. A debug image uses debugd as its bootstrapper binary, while release images use the actual bootstrapper Workflows for the main branch will always build debug images.

The image will be named and categorized depending on the branch the build is triggered from. In the following, Release refers to non debug images build from a release branch, e.g. release/v1.4.0, Debug refers to debug images build from either main or a release branch, and Branch refers to any image build from a branch that is not main or a release branch. Non debug images built from main follow the Branch image naming scheme.
