Deploying to Azure Kubernetes Service

Observação: no momento, não há suporte para os 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.

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_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.

env:
  AZURE_CONTAINER_REGISTRY: MY_REGISTRY_NAME # set this to the name of your container registry
  PROJECT_NAME: MY_PROJECT_NAME              # set this to your project's name

  CLUSTER_NAME: MY_CLUSTER_NAME              # set this to the name of your AKS cluster
  REGISTRY_URL: MY_REGISTRY_URL              # set this to the URL of your registry
  # If you bake using helm:
  CHART_PATH: MY_HELM_FILE                   # set this to the path to your helm file
  CHART_OVERRIDE_PATH: MY_OVERRIDE_FILES     # set this to an array of override file paths
