Configure cloud provider

[github-learning-lab]

Azure configuration

GitHub Actions is cloud agnostic, so any cloud will work. We'll show how to deploy to Azure in this course.

Azure resources

We'll use the following Azure resources in this course:

• A web app is how we'll be deploying our application to Azure.
• A resource group is a collection of resources, like web apps and virtual machines (VMs).
• An App Service plan is what runs our web app and manages the billing (our app should run for free).

Through the power of GitHub Actions, we can create, configure, and destroy these resources through our workflow files.

Step 5: Spin up, configure, and destroy Azure resources

⌨️ Activity: Use your workflow file to configure your cloud resources

1. Edit the .github/CHANGETHIS/spinup-destroy.yml file on this branch, or use this quick link. (We recommend opening the quick link in another tab.)
2. Rename the files to .github/workflows/spinup-destroy.yml
3. Change the value of the AZURE_WEBAPP_NAME: to gitstua-ttt-app
4. Commit your changes.

The file should look like this:

name: Configure Azure environment

  pull_request:
    types: [labeled]

env:
  PACKAGES_TOKEN: ${{secrets.PACKAGES_TOKEN}}
  AZURE_RESOURCE_GROUP: cd-with-actions

It looks like you took an action I didn't expect.

I expected you to commit the file .github/workflows/spinup-destroy.yml and set the variable AZURE_WEBAPP_NAME to start with your GitHub username. Please try that to continue!

Configuring your Azure environment

To deploy successfully to our Azure environment, we've created a new workflow with two jobs:

1. Set up Azure resources will run if the pull request contains a label with the name "spin up environment".
2. Destroy Azure resources will run if the pull request contains a label with the name "destroy environment".

In addition to each job, there's a few global environment variables:

• AZURE_RESOURCE_GROUP, AZURE_APP_PLAN, and AZURE_WEBAPP_NAME are names for our resource group, app service plan, and web app, respectively, which we'll reference over multiple steps and workflows
• AZURE_LOCATION lets us specify the region for the data centers, where our app will ultimately be deployed.

Setting up Azure resources

The first job sets up the Azure resources as follows:

1. Logs into your Azure account with the azure/login action. The AZURE_CREDENTIALS secret you created earlier is used for authentication.
2. Creates an Azure resource group by running az group create on the Azure CLI, which is pre-installed on the GitHub-hosted runner.
3. Creates an App Service plan by running az appservice plan create on the Azure CLI.
4. Creates a web app by running az webapp create on the Azure CLI.
5. Configures the newly created web app to use GitHub Packages by using az webapp config on the Azure CLI. Azure can be configured to use its own Azure Container Registry, DockerHub, or a custom (private) registry. In this case, we'll configure GitHub Packages as a custom registry.

Destroying Azure resources

The second job destroys Azure resources so that you do not use your free minutes or incur billing. The job works as follows:

1. Logs into your Azure account with the azure/login action. The AZURE_CREDENTIALS secret you created earlier is used for authentication.
2. Deletes the resource group we created earlier using az group delete on the Azure CLI.

Step 6: Approve the pull request

I've requested your approval on this pull request. Once you approve this, I will merge.

⌨️ Activity: Approve pull request adding the necessary configuration files

1. Apply the "spin up environment" label to this pull request
2. Wait for the GitHub Actions workflow to run and spin up your Azure environment. You can follow along in the Actions tab or in the pull request merge box.
3. Once it workflow succeeds, approve this pull request

I'll respond when I receive an approval on this pull request.
