Deploying to Azure Kubernetes Service

You can deploy your project to Azure Kubernetes Service (AKS) as part of your continuous deployment (CD) workflows.

注意

GitHub Enterprise Server 目前不支持 GitHub 托管的运行器。 可以在 GitHub public roadmap 上查看有关未来支持计划的更多信息。

Introduction

This guide explains how to use GitHub Actions to build and deploy a project to Azure Kubernetes Service.

注意

如果 GitHub Actions 工作流需要访问支持 OpenID Connect (OIDC) 的云提供商提供的资源，则可以将工作流配置为直接向云提供商进行身份验证。 这样就可以停止将这些凭据存储为长期存在的机密，并提供其他安全优势。 有关详细信息，请参阅“关于使用 OpenID Connect 进行安全强化”。 and Configuring OpenID Connect in Azure.

Prerequisites

Before creating your GitHub Actions workflow, you will first need to complete the following setup steps:

  1. 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.

  2. Create a secret called AZURE_CREDENTIALS to store your Azure credentials. For more information about how to find this information and structure the secret, see the Azure/login action 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_REGISTRY to the name of your container registry
  • PROJECT_NAME to the name of your project
  • RESOURCE_GROUP to the resource group containing your AKS cluster
  • CLUSTER_NAME to 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.

# GitHub 建议将操作固定到提交 SHA。
# 若要获取较新版本，需要更新 SHA。
# 还可以引用标记或分支，但该操作可能会更改而不发出警告。
