 ### Github authentication
-You need to authenticate with github [see this thread](https://github.community/t/docker-pull-from-public-github-package-registry-fail-with-no-basic-auth-credentials-error/16358/87) to pull even the publicly available images. To do so you need to create [Personal Access Token](https://github.com/settings/tokens/new) with `read:packages` scope and use it to authenticate your docker client with the Github Docker Registry.
