Add Simple Flask App to Azure via Azure Container Services and Azure Container Registry (ACA)

This repo walks you through the steps to deploy a simple hello world flask app (NoDB) to Azure Container Services (ACS) using the Azure Developer CLI.

System Prerequisites

• Azure CLI
• Docker

QuickStart (Deploy this Project) Estimated time: 8 minutes

The instructions to build this project are heavily inspired by Quickstart: Deploy your code to Azure Container Apps

If you want to deploy this project to Azure, follow these steps:

Instructions

text in code blocks are commands that you should enter into your terminal.

<Replace text in Brackets> with your own values. Follow the casing and spacing of the example:

• <ALLCAPS>
• <lowercase>
• <kebab-case>

follow the guidance in the comments foo # follow these notes

[OPTIONAL] Step 0: Ensure your container builds locally

docker build -t <yourname:yourtag> .
docker run -p <EXTERNALPORT:INTERNALPORT YOURNAME:YOURTAG> 

NOTE: # Ports are your port number 5000:5000 by default.

This ensures that your app itself is working and issues will not be caused by syntax or other issues.

Step 1: Set environment variables

Setting the variables below will make entering commands a little faster and more consistent.

1. RESOURCE_GROUP="<my-resource-group>"
2. LOCATION="<westus>" # Change to your preferred location
3. ENVIRONMENT="<my-environment>"
4. API_NAME="<my-api-name>"
5. UNQIUE="<my-unique-characters>" # try to be unique to avoid conflicts ACR_NAME="acaprojectname"+$UNIQUE # must be all lowercase
6. REGISTRY_SERVER=$ACR_NAME".azurecr.io"
7. IMAGE_URI=$ACR/$API_NAME

Step 2: Create A Resource Group

az group create \
--name $RESOURCE_GROUP \
--location $LOCATION

Step 3: Create a Container Registry

az acr create \
   --resource-group $RESOURCE_GROUP \
   --name $ACR_NAME \
   --sku Basic \
   --admin-enabled true

Step 4: Build Your Container

docker build -t $REGISTRY_SERVER . --platform linux/amd64

Step 5: Login into the Azure Container Registry

az acr login --name $REGISTRY_SERVER

Step 6: Push your container to the Azure Container Registry

docker push $IMAGE_URL

Step 7: Create an ACA Environment

az containerapp env create --resource-group $RESOURCE_GROUP --name $ENVIRONMENT --location $LOCATION

Step 6: Deploy Your Container to the Container App

az containerapp create \
--resource-group $RESOURCE_GROUP \
--name $API_NAME \
--environment $ENVIRONMENT \
--image $IMAGE_URI \
--target-port <INTERNALPORT> \
--ingress 'external' \
--registry-server $REGISTRY_SERVER \
