How to get started with Github’s new Docker Container Registry – CloudSavvy IT



GitHub logo.

GitHub recently released the GitHub Docker Container Registry, a competitor to the standard Docker Hub that lets you privately store Docker images in the cloud. It acts as an extension of GitHub packages and integrates with their existing CI / CD tools.

What is the GitHub Container Registry?

Docker container registers store built-in versions of Docker containers. The default is Docker Hub, which hosts most open source Docker containers. However, you are completely free to use another archive, and many companies choose to use a private register.

GitHub is in a particularly good position to offer a container registry, which is home to free open source software, and it̵

7;s actually surprising that it took them so long to bring one to market. But it is here now and integrates quite well with its existing services, making it one of the best competitors to the Docker Hub available today.

The container register serves as an extension of GitHub Packages, a package repository for package managers such as NPM and NuGet. All they add is an option to use it for Docker images as well as support for Docker CLI tools like push and pull.

The source code for the images, including Dockerfile, is all stored in a standard GitHub archive. Then, when you want to print an image, you can build it and shoot it to the associated image package for the repo.

Because both the source code and the Docker image are on GitHub, it provides a unique opportunity for integration. GitHub actions can be triggered by source code changes, which can automatically run builds of your image when changes are made to GitHub.

Cloud-to-cloud automation.

During the Container Registry beta, the container register will be free to use. Open source and public archives are always completely free to use, with

For private archives, the default billing rate for GitHub packages applies when the beta version is over. The free level includes 500 MB of storage and 1 GB of transfer per month, which should be enough for most projects. If not, you can invest in GitHub Teams or GitHub Enterprise.

How do you use it?

The URL of the new registry is ghcr.io, easy to remember and short to type, which is a must when you need to print it for each Docker command.

To get started, you must first create a personal access token from Settings> Developer settings> Personal access token.

Create a personal access token from Settings> Developer settings> Personal access token.  “Width =” 700 “height =” 148 “onload =” pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon (this);  “onerror =” this.onerror = null;  pagespeed.  lazyLoadImages.loadIfVisibleAndMaybeBeacon (this);  “/></p>
<p>Then you can log in to the registry with that token.  Technically, GitHub recommends that you put this in a file and send it through STDIN <code>cat</code>, but pasting it is good.</p>
<pre>docker login ghcr.io -u username</pre>
<p>Then run a standard Docker version, tag it with the repo URL and repository name and print the image.</p>
<pre>docker build . -t ghcr.io/username/repository/image:version
docker push ghcr.io/username/repository/image:version</pre>
<p>Note!  You need a real Git archive to associate this package with.</p>
<p>Once it has been fired, you should see a new package in your profile or listed under “Packages” in the repository.</p>

One of the best things you can do from here is create an automated CI / CD pipeline that builds your Docker image when changes are detected in Git. GitHub has a preventive measure called “Publish Docker Container” which will be published in the package register for the repository.

Publish Docker Container will publish in the package register for the repository.
