Introduction

This guide explains how to use GitHub Actions to build, test, and deploy a Node.js project to Azure App 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:

  1. Create an Azure App Service plan.

    For example, you can use the Azure CLI to create a new App Service plan:

    Bash
    az appservice plan create \
   --resource-group MY_RESOURCE_GROUP \
   --name MY_APP_SERVICE_PLAN \
   --is-linux

    In the command above, replace MY_RESOURCE_GROUP with your pre-existing Azure Resource Group, and MY_APP_SERVICE_PLAN with a new name for the App Service plan.

    See the Azure documentation for more information on using the Azure CLI:

  2. Create a web app.

    For example, you can use the Azure CLI to create an Azure App Service web app with a Node.js runtime:

    Bash
    az webapp create \
    --name MY_WEBAPP_NAME \
    --plan MY_APP_SERVICE_PLAN \
    --resource-group MY_RESOURCE_GROUP \
    --runtime "NODE|14-lts"

    In the command above, replace the parameters with your own values, where MY_WEBAPP_NAME is a new name for the web app.

  3. Configure an Azure publish profile and create an AZURE_WEBAPP_PUBLISH_PROFILE secret.

    Generate your Azure deployment credentials using a publish profile. For more information, see "Generate deployment credentials" in the Azure documentation.

    In your GitHub repository, create a secret named AZURE_WEBAPP_PUBLISH_PROFILE that contains the contents of the publish profile. For more information on creating secrets, see "Using secrets in GitHub Actions."

  4. Optionally, configure a deployment environment. Environments are used to describe a general deployment target like production, staging, or development. When a GitHub Actions workflow deploys to an environment, the environment is displayed on the main page of the repository. You can use environments to require approval for a job to proceed, restrict which branches can trigger a workflow, gate deployments with custom deployment protection rules, or limit access to secrets. For more information about creating environments, see "Managing environments for deployment."

Creating the workflow

Once you've completed the prerequisites, you can proceed with creating the workflow.

The following example workflow demonstrates how to build, test, and deploy the Node.js project to Azure App Service when there is a push to the main branch.

Ensure that you set AZURE_WEBAPP_NAME in the workflow env key to the name of the web app you created. If the path to your project is not the repository root, change AZURE_WEBAPP_PACKAGE_PATH to your project path. If you use a version of Node.js other than 10.x, change NODE_VERSION to the version that you use.

If you configured a deployment environment, change the value of environment to be the name of your environment. If you did not configure an environment or if your workflow is in a private repository and you do not use GitHub Enterprise Cloud, delete the environment key.

YAML
# 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.

  push:
    branches:
      - main

env:
  AZURE_WEBAPP_NAME: MY_WEBAPP_NAME   # set this to your application's name
  AZURE_WEBAPP_PACKAGE_PATH: '.'      # set this to the path to your web app project, defaults to the repository root
  NODE_VERSION: '14.x'                # set this to the node version to use
