Using the Azure Developer Cli and DevContainers with Codespaces

Overview

This repo is a simple example to show how to use the Azure Developer Cli for inner loop development in Azure.
It leverages Github Codespaces as a hosted developer environment.

Github Action

The repo also has two Github Action workflows that would be used to promote code into upper environments after changes are merged into the main branch.

• Create Azure Container Apps Environment
• Update a deployment to Azure Container Apps

Required Action Secrets

Variable	Usage
SIMPLE_AZURE_CREDENTIALS	Creds to access Azure
CONTAINER_APP_RG	Resource Group Name for the Upper Environment
CONTAINER_APP_NAME	Container App Environment Name for the Upper Environment
DOCKER_REPO	Container Registry for Upper Environment
SIMPLE_REGISTRY_USERNAME	User name for Container Registry
SIMPLE_REGISTRY_PASSWORD	User password for Container Registry

Prerequisite

• Azure Subscrption
• Github Codespaces

Deployed Azure Resources

• Azure Container Registry
• Azure Container Environment
• Azure Container App
• Azure PostgreSQL

Deploy Environment

    git checkout -b branch/feature1
    azd login --tenant-id $ARM_TENANT_ID --client-id $ARM_CLIENT_ID --client-secret $ARM_CLIENT_SECRET
    azd init 
        - Environment Name: dev
        - Azure Location: (US) Southcentral US
        - Azure Subscription: <ENTER> 
    azd up
    ./scripts/update-ui.sh

Validate

    ./scripts/validate.sh

Update Deployment

    //Update line 9 from 
    app.MapGet( "/", () =>  $"Hello World! The time now is {DateTime.Now}" );
    //To 
    app.MapGet( "/", () =>  $"Hello World, Updated! The time now is {DateTime.Now}" );

Redeploy and Validate

    azd deploy 
    ./scripts/validate.sh

Pull Request

• At this point, a developer would commit the code upstream to their branch and create a pull request. After approved then the Update a deployment to Azure Container Apps Github Action workflow will deploy the change to the upper environments.

Clean Up

    azd down

Backlog

• Create script to build and push docker image
• Create script to upate Container App with latest image
• Migrate to Dapr/PostgreSQL from InMemory Database
