How do I configure CircleCI to deploy a Golang app to Azure

Step 1: Create a CircleCI Configuration File

1. Create a new file named `.circleci/config.yml` in the root directory of your project.
2. Specify the version of CircleCI in the file:

yaml
   version: 2.1
   

Step 2: Use the Go Orb

1. Add the Go orb to your configuration file:

yaml
   orbs:
     go: circleci/go@1.7.3
   

Step 3: Define Jobs

1. Define two jobs: `build_and_test` and `deploy`:

yaml
   jobs:
     build_and_test:
       executor:
         name: go/default
         tag: '1.19.2'
       steps:
         - checkout
         - go/load-cache
         - go/mod-download
         - go/save-cache
         - go/test:
             covermode: atomic
             failfast: true
             race: true
         - persist_to_workspace:
             root: ~/project
             paths: .
     deploy:
       executor: heroku/default
       steps:
         - attach_workspace:
             at: ~/project
         - heroku/deploy-via-git:
             force: true
   

Step 4: Define a Workflow

1. Define a workflow named `test_my_app` that includes both jobs:

yaml
   workflows:
     test_my_app:
       jobs:
         - build_and_test
         - deploy:
           requires:
             - build_and_test
           filters:
             branches:
               only: main
   

Step 5: Configure Azure Deployment

1. Create an Azure Service Principal and add the credentials as environment variables in CircleCI:

yaml
   environment:
     AZURE_SP_TENANT: $AZURE_SP_TENANT
     AZURE_SP: $AZURE_SP
     AZURE_SP_PASSWORD: $AZURE_SP_PASSWORD
   

Step 6: Update the Deploy Job

1. Update the `deploy` job to use the Azure credentials:

yaml
   deploy:
     executor: heroku/default
     steps:
       - attach_workspace:
           at: ~/project
       - heroku/deploy-via-git:
           force: true
   

Step 7: Connect to Azure

1. Connect to Azure by specifying the Azure credentials in the `deploy` job:

yaml
   deploy:
     executor: heroku/default
     steps:
       - attach_workspace:
           at: ~/project
       - heroku/deploy-via-git:
           force: true
           azure:
             tenant: $AZURE_SP_TENANT
             client: $AZURE_SP
             password: $AZURE_SP_PASSWORD
   

Step 8: Push Changes to GitHub

1. Push your changes to GitHub to trigger the CircleCI workflow:

bash
   git add .
   git commit -m "Initial commit"
   git push origin main
   

Step 9: Monitor Deployment

1. Monitor the deployment in the CircleCI dashboard:

bash
   CircleCI dashboard
   

By following these steps, you can configure CircleCI to deploy your Golang app to Azure.
