GitHub actions for Kubernetes

GitHub actions for deploying to a Kubernetes cluster for example Azure Kubernetes service (AKS).

The repository contains the following GitHub actions:

• k8s-set-context: Used for setting the target K8s cluster context by providing kubeconfig or service account details
• aks-set-context: Used for setting the target AKS cluster context by providing Azure subscription details
• k8s-create-secret : Create a generic secret or docker-registry secret in Kubernetes cluster.
• K8s-deploy: Deploy manifest action for Kubernetes to bake and deploy manifests to a Kubernetes cluster.
• setup-kubectl: Install a specific version of kubectl binary on runner

Usage

Usage information for individual actions can be found in their respective directories.

For any credential like Azure Service Principal, Kubeconfig, add them as secrets in the GitHub repository and then use them in the workflow.

In the above example the secret name is REGISTRY_USERNAME and REGISTRY_PASSWORD and it can be used in the workflow by using the following syntax:

container-registry-username: ${{ secrets.REGISTRY_USERNAME }}
