Azure Spring Apps

GitHub Action for deploying to Azure Spring Apps

GitHub Actions support an automated software development lifecycle workflow. With GitHub Actions for Azure Spring Apps you can create workflows in your repository to manage your deployment of Azure Spring Apps conveniently.

Prerequisites

Set up GitHub repository and authenticate

You need an Azure service principal credential to authorize Azure login action. To get an Azure credential, execute the following commands on your local machine:

az login
az ad sp create-for-rbac --role contributor --scopes /subscriptions/<SUBSCRIPTION_ID> --sdk-auth

To access to a specific resource group, you can reduce the scope:

az ad sp create-for-rbac --role contributor --scopes /subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<RESOURCE_GROUP> --sdk-auth

The command should output a JSON object:

{
  "clientId": "<GUID>",
  "clientSecret": "<GUID>",
  "subscriptionId": "<GUID>",
  "tenantId": "<GUID>",
  ...
}

Dependencies on other GitHub Actions

Checkout Checkout your Git repository content into GitHub Actions agent.
Authenticate using the Azure Login Action with the Azure service principal credential prepared as mentioned above. Examples are given later in this article.

End-to-End Sample Workflows

Deploying

To production

Azure Spring Apps supports deploying to deployments with built artifacts (e.g., JAR or .NET Core ZIP) or source code archive. The following example deploys to the default production deployment in Azure Spring Apps using JAR file built by Maven. This is the only possible deployment scenario when using the Basic SKU:

name: AzureSpringApps
on: push
env:
  ASC_PACKAGE_PATH: ${{ github.workspace }}
  AZURE_SUBSCRIPTION: <azure subscription id>

jobs:
  deploy_to_production:
    runs-on: ubuntu-latest
    name: deploy to production with artifact
    steps:
      - name: Checkout Github Action
        uses: actions/checkout@v2
        
      - name: Set up JDK 1.8
        uses: actions/setup-java@v1
        with:
          java-version: 1.8

      - name: maven build, clean
        run: |
          mvn clean package

      - name: Login via Azure CLI
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: deploy to production with artifact
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: Deploy
          service-name: <service instance name>
          app-name: <app name>
          use-staging-deployment: false
          package: ${{ env.ASC_PACKAGE_PATH }}/**/*.jar

The following example deploys to the default production deployment in Azure Spring Apps using source code.

name: AzureSpringApps
on: push
env:
  ASC_PACKAGE_PATH: ${{ github.workspace }}
  AZURE_SUBSCRIPTION: <azure subscription id>

jobs:
  deploy_to_production:
    runs-on: ubuntu-latest
    name: deploy to production with soruce code
    steps:
      - name: Checkout Github Action
        uses: actions/checkout@v2

      - name: Login via Azure CLI
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: deploy to production step with soruce code
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: deploy
          service-name: <service instance name>
          app-name: <app name>
          use-staging-deployment: false
          package: ${{ env.ASC_PACKAGE_PATH }}

Blue-green

The following examples deploy to an existing staging deployment. This deployment will not receive production traffic until it is set as a production deployment. You can set use-staging-deployment true to find the staging deployment automatically or just allocate specific deployment-name. We will only focus on the spring-apps-deploy action and leave out the preparatory jobs in the rest of the article.

# environment preparation configurations omitted
    steps:
      - name: blue green deploy step use-staging-deployment
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: deploy
          service-name: <service instance name>
          app-name: <app name>
          use-staging-deployment: true
          package: ${{ env.ASC_PACKAGE_PATH }}/**/*.jar

# environment preparation configurations omitted
    steps:
      - name: blue green deploy step with deployment-name
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: deploy
          service-name: <service instance name>
          app-name: <app name>
          deployment-name: staging
          package: ${{ env.ASC_PACKAGE_PATH }}/**/*.jar

For more information on blue-green deployments, including an alternative approach, see Blue-green deployment strategies.

Creating new deployment

The following example shows how to create a new staing deployment. CPU and memory can be allocated when creating new deployment.

# environment preparation configurations omitted
    steps:
      - name: blue green deploy step with deployment-name
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: deploy
          service-name: <service instance name>
          app-name: <app name>
          create-new-deployment: true
          deployment-name: staging
          cpu: <cpu>
          memory: <memory>
          package: ${{ env.ASC_PACKAGE_PATH }}/**/*.jar

Custom container image support

To deploy directly from a existing container image, use the following template.

# environment preparation configurations omitted
    steps:
      - name: Deploy custom container image
        uses: Azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: deploy
          service-name: <service instance name>
          app-name: <app name>
          deployment-name: <deployment name>
          container-registry: <container registry>
          registry-username: <registry username>
          registry-password: <registry password>
          container-image: <container image>

Setting production deployment

The following example will set the current staging deployment as production, effectively swapping which deployment will receive production traffic.

# environment preparation configurations omitted
    steps:
      - name: set production deployment step
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: set-production
          service-name: <service instance name>
          app-name: <app name>
          use-staging-deployment: true

Deleting a staging deployment

The "Delete Staging Deployment" action allows you to delete the deployment not receiving production traffic. This frees up resources used by that deployment and makes room for a new staging deployment:

# environment preparation configurations omitted
    steps:
      - name: Delete staging deployment step
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: delete-staging-deployment
          service-name: <service instance name>
          app-name: <app name>

Create or update build

The following example will create or update an build resource.

# environment preparation configurations omitted
    steps:
      - name: Create or update build
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: build
          service-name: <service instance name>
          build-name: <build name>
          package: ${{ env.ASC_PACKAGE_PATH }}
          builder: <builder>

Delete build

The following example will delete an build resource.

# environment preparation configurations omitted
    steps:
      - name: Delete build
        uses: azure/spring-apps-deploy@v1
        with:
          azure-subscription: ${{ env.AZURE_SUBSCRIPTION }}
          action: delete-build
          service-name: <service instance name>
          build-name: <build name>
