Publish to GitHub Packages

Use GitHub Actions to publish your project to a Docker image.

Step 4: Pull your image

Now things are running! ✨

Whoa, now things are running! This may take a few minutes. This might take a tiny amount of time, so grab your popcorn 🍿 and wait for the build to finish before moving on.

To pull the Docker image, we need to log into Docker first.

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.

Open your terminal (Bash or Git Bash recommended).
Use the following command to log in:
```
docker login ghcr.io -u USERNAME
```
Replace USERNAME with your GitHub username.
Enter your new Personal Access Token as the password.
Press Enter.

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

⌨️ Activity: Pull your image

Copy and paste the pull command from the package instructions into your terminal. It should look something like this:
- docker pull ghcr.io/YOURNAME/publish-packages/game:TAG
- Tip: To reach this page, click the Code tab at the top of your repository. Then, find the navigation bar below the repository description, and click the Packages heading link
Replace YOURNAME with your GitHub username.
Replace TAG with the image tag.
Press Enter.
You should see output indicating that the pull was successful, like Status: Downloaded newer image for ghcr.io/YOURNAME/publish-packages/game:TAG.

Step 5: Run your image

Nicely done grabbing your Docker image! ☺️

Let's trying running it.

⌨️ Activity: Run your image

Find your image information by typing docker image ls.
Use the following command to run a container from your image:
```
docker run -dp 8080:80 --rm <YOUR_IMAGE_NAME:TAG>
```
Replace YOUR_IMAGE_NAME with your image name under the REPOSITORY column.
Replace TAG with the image tag under the TAG column.
Press Enter.
If everything went well, you will see hash value as output on your screen.
Optionally, you can open localhost:8080 to see the page you just created.

Finish

Congratulations friend, you've completed this course!

Here's a recap of all the tasks you've accomplished in your repository:

You wrote a workflow that sends a code through a continuous delivery pipeline.
You built a fully deployable artifact.
You did so using GitHub Actions and GitHub Packages!
