GitHub Action for deploying to Azure Container Instances

GitHub Actions gives you the flexibility to build an automated software development lifecycle workflow.

You can automate your workflows to deploy to Azure Container Instances using GitHub Actions.

This repository contains GitHub Action for Deploying to Azure Container Instances to deploy to Azure Container Instances. It supports deploying your container image to an Azure Container Instance.

Note:

1. Currently this action supports deploying to azure container instances only if the ip-Address of the container group is public.
2. If you are going to update the OS-type, restart policy, network profile, CPU, memory or GPU resources for a container group using workflow, you must delete the container group first and then create a new one.

The definition of this GitHub Action is in action.yml.

End-to-End Sample Workflows

Dependencies on other GitHub Actions

• Azure Login Login with your Azure Credentials for Authentication. Once login is done, the next set of Azure Actions in the workflow can re-use the same session within the job.

Azure Service Principal for RBAC

For using any credentials like Azure Service Principal in your workflow, add them as secrets in the GitHub Repository and then refer them in the workflow.

1. Download Azure CLI from here, run az login to login with your Azure Credentials.
2. Run Azure CLI command to create an Azure Service Principal for RBAC:

    az ad sp create-for-rbac --name "myApp" --role contributor \
                             --scopes /subscriptions/{subscription-id}/resourceGroups/{resource-group} \
                             --sdk-auth
    
    # Replace {subscription-id}, {resource-group} with the subscription, resource group details of the WebApp
    # The command should output a JSON object similar to this:

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

• You can further scope down the Azure Credentials to the Web App using scope attribute. For example,

 az ad sp create-for-rbac --name "myApp" --role contributor \
                          --scopes /subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Web/sites/{app-name} \
                          --sdk-auth

# Replace {subscription-id}, {resource-group}, and {app-name} with the names of your subscription, resource group, and Azure Web App.

3. Paste the json response from above Azure CLI to your GitHub Repository > Settings > Secrets > Add a new secret > AZURE_CREDENTIALS
4. Now in the workflow file in your branch: .github/workflows/workflow.yml replace the secret in Azure login action with your secret (Refer to the example below)

Example YAML Snippets

Deploying a Container from a public registry

- uses: Azure/aci-deploy@v1
  with:
    resource-group: contoso
    dns-name-label: url-for-container
    image: nginx
    name: contoso-container
    location: 'east us'

Deploying a Container with Volumes (from Azure File Share or GitHub Repositories)

- uses: Azure/aci-deploy@v1
  with:
    resource-group: contoso
    dns-name-label: url-for-container
    image: nginx
    name: contoso-container
    azure-file-volume-share-name: shareName

    azure-file-volume-account-key: ${{ secrets.AZURE_FILE_VOLUME_KEY }}
    azure-file-volume-mount-path: /mnt/volume1
    location: 'east us'

Deploying a Container with Environment Variables and Command Line

NOTE: The values of secure-environment-variables will not be shown in the properties of the Azure Container Instance, but will be shown in the logs of the GitHub Action unless you specify them as Secrets.

Your environment variable names must start with a alphabetic character or _.

- uses: Azure/aci-deploy@v1
  with:
    resource-group: contoso
    dns-name-label: url-for-container
    image: nginx
    name: contoso-container
    command-line: /bin/bash a.sh
    environment-variables: key1=value1 key2=value2
    secure-environment-variables: key1=${{ secrets.ENV_VAL1 }} key2=${{ secrets.ENV_VAL2 }}
    location: 'east us'

Local Development and Testing

If you wish to develop and test changes against a local fork or development repo, you can do so by including the node_modules in tagged release branch. Note that the aci-deploy repository does not include these modules in the master branch, so you cannot point your action to aci-deploy/master to pick up recent commits.

Testing can be performed against your local repo by performing the following:

• Fork this repo.
• Create a separate branch on your local copy. This will be used to execute the action from your workflow.
• Perform an npm install and npm run build
• Ensure that you check in the node_modules directory to your branch.
• Update your workflow to refer to your tagged release from forked copy.
