Docker Course Labs

Lab Solution

The default registry is Docker Hub - using the domain docker.io, and the default image tag is latest.

So kiamol/ch05-pi is the short form of docker.io/kiamol/ch05-pi:latest:

docker pull kiamol/ch05-pi

docker pull docker.io/kiamol/ch05-pi:latest

Check the image list and you'll only see one - these aren't aliases, they're just different froms of the same name:

docker image ls kiamol/ch05-pi

Be wary of using latest images - it's a confusing name because it might not be the latest version.

For other registries you need to include the domain in the reference - so images on MCR need to be prefixed with mcr.microsoft.com/:

docker pull mcr.microsoft.com/dotnet/runtime:5.0
