Commands reference

What this covers

This is the command cheat sheet for the Quote API project. It groups the local Docker commands, the Azure Container Registry commands that build, store and version the image, the ACR Tasks commands that automate builds, and the Azure Container Apps commands that run it. Use it as a lookup while you work through the project. The exam tests which command fits which job, so the comparison table under Exam traps is the part to memorize.

Exam weight: Develop containerized solutions on Azure (20–25%)

• "Build, store, version, and manage container images by using Azure Container Registry"
• "Build and run images by using Azure Container Registry Tasks"

Key concepts

Three ways to build in ACR

Task triggers

• Source commit (on by default when the context is a GitHub or Azure Repos URL) and pull request (off by default). Both need a personal access token so ACR can create the webhook.
• Base image update: rebuilds the app image when its base image is updated in ACR or a public registry.
• Timer: one or more cron schedules in UTC (--schedule).

Image versioning

Push a unique tag (a version or the run ID) for every build and treat latest as a convenience alias. az acr repository show-tags and az acr repository show-manifests show what is stored.

How it works

Hands-on

Azure portal

1. In the registry, open Services > Repositories to browse images and tags.
2. Open Services > Tasks to see saved tasks; the Runs tab lists every run with its logs.
3. In the container app, open Monitoring > Log stream to watch the running API.

ACR Tasks

GitHub-triggered task (builds on every commit to main):

az acr task create \
  -n quote-api-github-build \
  -r quoteapiacr \
  -f acr-task.yaml \
  --context https://github.com/YOUR-ORG/YOUR-REPO.git#main \
  --git-access-token YOUR_GITHUB_PAT \
  --commit-trigger-enabled true

Scheduled task (nightly at 2 AM UTC, no commit trigger):

az acr task create \
  -n quote-api-nightly \
  -r quoteapiacr \
  -f acr-task.yaml \
  --context https://github.com/YOUR-ORG/YOUR-REPO.git#main \
  --git-access-token YOUR_GITHUB_PAT \
  --commit-trigger-enabled false \
  --schedule "0 2 * * *"

Container Apps

API endpoints

Python

Smoke-test the deployed API after a build:

import requests

base = "https://<container-app-fqdn>"
assert requests.get(f"{base}/health", timeout=10).status_code == 200
print(requests.get(f"{base}/quotes/random", timeout=10).json())

Exam traps

Quick review

• az acr build = quick task from a Dockerfile; az acr run = one-off multi-step YAML.
• az acr task create saves a task with commit, base-image or timer triggers.
• Commit triggers are on by default for Git contexts and need a PAT.
• az acr task logs --run-id retrieves logs for triggered runs.
• az acr repository show-tags lists the versions you have stored.
• az containerapp update --image deploys a new image as a new revision.
