Back to Deploy and operate containers on Azure App Service

Project: Example — Deploying a container to Azure Container Apps

Deploy script explained

Overview

What deploy.sh / deploy.ps1 runs, step by step — from resource group to a live Container App.

Step 1 — Create resource group

Azure CLI
az group create --name "$RESOURCE_GROUP" --location "$LOCATION" --output none
FlagMeaning
--nameResource group (default: quote-api-rg)
--locationAzure region (default: eastus)
--output noneQuiet output

Why: Keep ACR + Container Apps together for billing, RBAC, and easy cleanup (az group delete).

Step 2 — Create Azure Container Registry

Azure CLI
az acr create \
  --resource-group "$RESOURCE_GROUP" \
  --name "$ACR_NAME" \
  --sku Basic \
  --admin-enabled true \
  --output none
FlagMeaning
--sku BasicLowest cost SKU for learning
--admin-enabled trueUsername/password so Container Apps can pull

Why: Private registry near your Azure deploy for the Quote API image.

Step 3 — Build and push (az acr build)

Azure CLI
az acr build \
  --registry "$ACR_NAME" \
  --image "${IMAGE_NAME}:latest" \
  --file "$PROJECT_DIR/Dockerfile" \
  "$PROJECT_DIR"

What it does: Uploads source to Azure, builds in the cloud, pushes to ACR — a Quick Task with no local Docker required.

Step 4 — Create Container Apps environment

Azure CLI
az containerapp env create \
  --name "$CONTAINERAPPS_ENV" \
  --resource-group "$RESOURCE_GROUP" \
  --location "$LOCATION" \
  --output none

Why: Apps must live inside an environment (shared networking/logging). One env can host many apps.

Step 5 — Deploy Container App

Fetch ACR credentials:

Azure CLI
ACR_LOGIN=$(az acr show --name "$ACR_NAME" --query loginServer -o tsv)
ACR_USER=$(az acr credential show --name "$ACR_NAME" --query username -o tsv)
ACR_PASS=$(az acr credential show --name "$ACR_NAME" --query "passwords[0].value" -o tsv)

Create the app:

Azure CLI
az containerapp create \
  --name "$CONTAINER_APP" \
  --resource-group "$RESOURCE_GROUP" \
  --environment "$CONTAINERAPPS_ENV" \
  --image "${ACR_LOGIN}/${IMAGE_NAME}:latest" \
  --registry-server "$ACR_LOGIN" \
  --registry-username "$ACR_USER" \
  --registry-password "$ACR_PASS" \
  --target-port 8000 \
  --ingress external \
  --min-replicas 1 \
  --max-replicas 3 \
  --cpu 0.5 \
  --memory 1.0Gi \
  --env-vars APP_NAME="Quote API" ENVIRONMENT=production LOG_LEVEL=INFO \
  --output none
FlagMeaning
--target-port 8000Matches Uvicorn in the Dockerfile
--ingress externalPublic HTTPS
--min-replicas / --max-replicasScale bounds
--cpu / --memoryPer-replica resources
--env-varsRuntime configuration

Result: Quote API live on Azure with managed HTTPS, scaling, and restarts.

Exam / revision tips

  • Environment before app
  • --target-port must match container listen port
  • Admin credentials used here for learning; production often prefers managed identity + AcrPull
