Using your new Docker Image package

The easiest way to use your Docker Image package is to click the package name from the package tab.

That will bring you to a screen like containing instructions.

Before we can use this Docker image, you will need to generate a personal access token that contains the following permissions:

  • repo (all)
  • write:packages
  • read:packages

We will use this token to log in to Docker, and authenticate with the package.

Step 4: Log in to Docker

⌨️ Activity: Log in to Docker

  1. Open your terminal (Bash or Git Bash recommended)
  2. Use the following command to log in: 
    docker login docker.pkg.github.com -u USERNAME -p TOKEN
  3. Replace USERNAME with your GitHub username
  4. Replace TOKEN with the Personal Access Token you just created
  5. Press Enter

If everything went well, 🤞you should see Login Succeeded in your terminal.

Step 5: Pull your image

⌨️ Pull the image from GitHub Packages to your local environment

  1. Copy and paste the pull command from the package instructions into your terminal. It should look something like this:
  • docker pull docker.pkg.github.com/cdb/js-build/tic-tac-toe:f29

  1. Press Enter

You should see output indicating that the pull was successful, like Status: Downloaded newer image for docker.

Step 6: Run your Docker Image

⌨️ Activity: Run your image locally

  1. Find your image information by typing Docker image ls

  2. Use the following command to run a container from your image:
    docker run -d -it --rm -p 8080:80 --name ttt <YOUR_IMAGE_NAME:TAG>
  3. Replace YOUR_IMAGE_NAME with your image name under the REPOSITORY column
  4. Replace TAG with the image tag under the TAG column
    example of running the docker command listed above
  5. Press Enter

If everything went well, you will see hash value as output on your screen.
