Guided Task

Write Your First GitHub Actions Workflow

A pipeline is a file in the repository — that's the whole trick. Create the exact directory layout GitHub Actions expects and write a workflow that runs on every push.

Environment: ubuntu:24.04Launch Lab ⚡

TOPIC 02

Jobs & Testing

Make the pipeline prove something.

What you'll practice

Run Tests in the Pipeline — practice · beginner

A command you'll meet

cat ~/project/.github/workflows/ci.yml

Open any task below to get the full step-by-step walkthrough — every command is explained, and the lab validator checks what you actually built.

Hands-On Tasks in This Topic (1)

beginner

Practice Task

Run Tests in the Pipeline

A pipeline that only checks out code proves nothing. Extend the workflow so it installs dependencies and runs the test suite on every push.

Environment: ubuntu:24.04Launch Lab ⚡

TOPIC 03

Build & Push Images

Ship a container image from the pipeline.

What you'll practice

Build and Push a Docker Image in CI — practice · intermediate

A command you'll meet

echo '      - uses: docker/login-action@v3' >> ~/project/.github/workflows/ci.yml

Practice Task

Build and Push a Docker Image in CI

The final pipeline stage for most services: build an image and publish it to a registry. Extend the workflow with Docker build and push steps.

TOPIC 04

Deployments & Secrets

Ship from the pipeline — without leaking credentials into the repository.

What you'll practice

Guard the Deploy Secrets — practice · intermediate

A command you'll meet

echo ' - run: ./deploy.sh' >> ~/project/.github/workflows/deploy.yaml

Open any task below to get the full step-by-step walkthrough — every command is explained, and the lab validator checks what you actually built.

Hands-On Tasks in This Topic (1)

Practice Task

Guard the Deploy Secrets

A deploy workflow needs AWS credentials — and pasting them into the YAML is how leaks happen. Write a deploy workflow that reads its keys from GitHub Secrets, then record the secret inventory in a checklist file so the next engineer knows what exists and where it lives.

Environment: ubuntu:24.04Launch Lab ⚡

TOPIC 05

Release Pipelines

Promotion, approval gates and matrix builds - the parts of CI/CD that touch production.

What you'll practice

Add an Approval Gate to a Deployment — practice · intermediate
Build a Version Matrix — challenge · advanced

A command you'll meet

cat ~/ci/deploy.yml

The pipeline is a product too - it has to be safe to run. Open the task below for the full walkthrough.

Hands-On Tasks in This Topic (2)

intermediate

Practice Task

Add an Approval Gate to a Deployment

Production deployments should need a human. Extend a pipeline with a manual trigger and an environment that requires approval before anything ships.

Environment: ubuntu:24.04Launch Lab ⚡

advanced

Challenge

Build a Version Matrix

One pipeline, many versions. Declare a matrix strategy so every job runs once per Python version and the matrix grows without editing the file.
