💡 Hint

Common Mistakes

Using a GitHub Action name instead of a Docker image.

Using a runner label like 'ubuntu-latest' as image.

The container.image field specifies the Docker image to run the job in. Here, node:14 is a valid Docker image.

Complete the code to check out the repository in a GitHub Actions workflow step.

Docker

- name: Checkout code
  uses: [1]

Drag options to blanks, or click blank then click option'

Aactions/checkout@v3

Bdocker/build-push-action@v3

Cactions/setup-node@v3

Dactions/upload-artifact@v3

Attempts:

💡 Hint

Common Mistakes

Using a build or setup action instead of checkout.

Using an upload artifact action here.

The actions/checkout@v3 action checks out your repository code so the workflow can access it.

Fix the error in the step to build and push a Docker image using the official GitHub Action.

  with:
    context: .

Dtrue

💡 Hint

Common Mistakes

Using misspelled boolean values like 'falsee'.

Using strings like 'yes' or numbers like '1'.

The push input expects a boolean value true or false. Here, true enables pushing the image.

Fill both blanks to set environment variables for Docker Hub username and password in the workflow step.

Docker

  with:
    username: ${{ secrets.[1] }}
    password: ${{ secrets.[2] }}

Drag options to blanks, or click blank then click option'

BGITHUB_TOKEN

CDOCKER_PASSWORD

DAWS_SECRET

💡 Hint

Common Mistakes

Using unrelated secrets like 'GITHUB_TOKEN' or 'AWS_SECRET'.

Mixing up username and password secret names.

You store your Docker Hub username and password as secrets named DOCKER_USERNAME and DOCKER_PASSWORD. These are referenced here.

5fill in blank

hard

Fill all three blanks to build a Docker image with a tag and push it using the GitHub Actions Docker build-push action.

Docker

- name: Build and push Docker image
  uses: docker/build-push-action@v3
  with:
    context: [1]
    push: [2]
    tags: [3]

Drag options to blanks, or click blank then click option'

A.

Btrue

Cmyuser/myapp:latest

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'false' for push when you want to push.

Using wrong context path.

Missing or incorrect image tag.

The context is the build folder, usually .. push must be true to push the image. tags is the image name and tag.
