Kubernetes create secret

Create a generic secret or docker-registry secret in Kubernetes cluster, replacing the secret if it already exists.

The secret will be created in the cluster context which was set earlier in the workflow by using either azure/aks-set-context or azure/k8s-set-context

Refer to the action metadata file for details about all the inputs https://github.com/Azure/k8s-create-secret/blob/master/action.yml

For docker-registry type secrets, the fields .dockercfg or .dockerconfigjson can be supplied in plaintext on the string-data JSON object, or base64 encoded on the data JSON object as included in the docker-config-secrets section.

Sample workflow for docker-registry secret (imagepullsecret, stringData)

# File: .github/workflows/workflow.yml

on: push

jobs:
   example-job:
      runs-on: ubuntu-latest
      steps:
         - name: Set imagePullSecret
           uses: azure/k8s-create-secret@v4
           with:
              namespace: 'myapp'
              secret-name: 'contoso-cr'
              container-registry-url: 'containerregistry.contoso.com'
              container-registry-username: ${{ secrets.REGISTRY_USERNAME }}
              container-registry-password: ${{ secrets.REGISTRY_PASSWORD }}
           id: create-secret

Sample workflow for generic secret (base64 data)

# File: .github/workflows/workflow.yml

on: push

jobs:
   example-job:
      runs-on: ubuntu-latest
      steps:
         - uses: azure/k8s-create-secret@v2
           with:
              namespace: 'default'
              secret-type: 'generic'
              secret-name: azure-storage
              data: ${{ secrets.AZURE_STORAGE_ACCOUNT_DATA }}

Alternative for Container Registry Secrets

Get the username and password of your container registry and create secrets for them. For Azure Container registry refer to admin account document for username and password.

For creating docker-registery secrets, kubectl can generate the JSON

kubectl create secret docker-registry secret-tiger-docker \
  --docker-username=tiger \
  --docker-password=pass113 \
  --docker-email=tiger@acme.com \
  --docker-server=my-registry.example:5000

Example output:

{
    "apiVersion": "v1",
    "data": {
        ".dockerconfigjson": "eyJhdXRocyI6eyJteS1yZWdpc3RyeTo1MDAwIjp7InVzZXJuYW1lIjoidGlnZXIiLCJwYXNzd29yZCI6InBhc3MxMTMiLCJlbWFpbCI6InRpZ2VyQGFjbWUuY29tIiwiYXV0aCI6ImRHbG5aWEk2Y0dGemN6RXhNdz09In19fQ=="
    },
    "kind": "Secret",
    "metadata": {
        "creationTimestamp": "2021-07-01T07:30:59Z",
        "name": "secret-tiger-docker",
        "namespace": "default",
        "resourceVersion": "566718",
        "uid": "e15c1d7b-9071-4100-8681-f3a7a2ce89ca"
    },
    "type": "kubernetes.io/dockerconfigjson"
}

Testing

Unit tests are run with jest with ts-jest and can be found in the ./test directory

Integration tests use Minikube and are executed within workflows in ./github/workflows
