GitHub Actions for Azure Kubernetes service or any generic Kubernetes cluster

GitHub Actions gives you the flexibility to build an automated software development lifecycle workflow.

A set of GitHub Actions for deploying to a Kubernetes cluster, including Azure Kubernetes service (AKS) and any generic Kubernetes cluster.

Get started today with a free Azure account!

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

The container-actions contains:

• docker-login : Actions to log in to a private container registry such as Azure Container registry. Once login is done, the next set of Actions in the workflow can perform tasks such as building, tagging and pushing containers.

The docker-login Actions in this repository (k8s-actions) will be deleted in the near future. Please use the Docker Actions from container-actions.

Azure Actions repository has a list of all the GitHub Actions for Azure.

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 }}
