Note: GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.
Introduction
This guide explains how to use GitHub Actions to build and deploy a project to Azure Kubernetes Service.
Note: If your GitHub Actions workflows need to access resources from a cloud provider that supports OpenID Connect (OIDC), you can configure your workflows to authenticate directly to the cloud provider. This will let you stop storing these credentials as long-lived secrets and provide other security benefits. For more information, see "About security hardening with OpenID Connect" and "Configuring OpenID Connect in Azure."
Prerequisites
Before creating your GitHub Actions workflow, you will first need to complete the following setup steps:
-
Create a target AKS cluster and an Azure Container Registry (ACR). For more information, see "Quickstart: Deploy an AKS cluster by using the Azure portal - Azure Kubernetes Service" and "Quickstart - Create registry in portal - Azure Container Registry" in the Azure documentation.
-
Create a secret called
AZURE_CREDENTIALSto store your Azure credentials. For more information about how to find this information and structure the secret, see theAzure/loginaction documentation.
Creating the workflow
Once you've completed the prerequisites, you can proceed with creating the workflow.
The following example workflow demonstrates how to build and deploy a project to Azure Kubernetes Service when code is pushed to your repository.
Under the workflow env key, change the following values:
AZURE_CONTAINER_REGISTRYto the name of your container registryPROJECT_NAMEto the name of your projectRESOURCE_GROUPto the resource group containing your AKS clusterCLUSTER_NAMEto the name of your AKS cluster
This workflow uses the helm render engine for the azure/k8s-bake action. If you will use the helm render engine, change the value of CHART_PATH to the path to your helm file. Change CHART_OVERRIDE_PATH to an array of override file paths. If you use a different render engine, update the input parameters sent to the azure/k8s-bake action.
# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.
# GitHub recommends pinning actions to a commit SHA.
# To get a newer version, you will need to update the SHA.
# You can also reference a tag or branch, but the action may change without warning.
