Deploying to Azure Kubernetes Service

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

Observação

No momento, não há suporte para executores hospedados no GitHub no GitHub Enterprise Server. Você pode ver mais informações sobre o suporte futuro planejado no GitHub public roadmap.

Introduction

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

Observação

Se os seus fluxos de trabalho de GitHub Actions tiverem de acessar recursos de um provedor de nuvem compatível com o OpenID Connect (OIDC), você poderá configurar seus fluxos de trabalho para efetuar a autenticção diretamente no provedor de nuvem. Isso permitirá que você pare de armazenar essas credenciais como segredos de longa duração e proporcione outros benefícios de segurança. Para saber mais, confira Sobre o enrijecimento de segurança com o 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:

  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.

YAML
# Esse fluxo de trabalho usa ações que não são certificadas pelo GitHub.
# São fornecidas por terceiros e regidas por
# termos de serviço, política de privacidade e suporte separados
# online.

# O GitHub recomenda fixar ações em um SHA de commit.
# Para obter uma versão mais recente, você precisará atualizar o SHA.
# Você também pode fazer referência a uma marca ou branch, mas a ação pode ser alterada sem aviso.
