Motivation

Microsoft moved their Container images from Docker Hub to their own Container registry=> https://azure.microsoft.com/en-gb/blog/microsoft-syndicates-container-catalog/

...

So I need to find a user friendly way to browse the images at https://mcr.microsoft.com

The HOW

Fun fact. Microsoft did not reuse their own Azure Container Registry to build the mcr.microsoft.com. They created something new and added parts of the Thankfully, Microsoft have implemented the interface of Docker Registry HTTP API V2 => https://cloudblogs.microsoft.com/opensource/2019/01/17/improved-discovery-experience-microsoft-containers-docker-hub/

So what can we dohow to use this?

First, open the docs Docker Registry HTTP API V2Start Postman and execute to read the specifiations.

Second, I have shared all the Postman samples here => https://documenter.getpostman.com/view/43927/SVSDPWkN

To list all the repositories at mcr.microsoft.com:

https://mcr.microsoft.com/v2/_catalog

To find the size of the Container Image:

• Add "Accept:application/vnd.docker.distribution.manifest.v2+json" in the header to change response format. The format is documented here => https://docs.docker.com/registry/spec/manifest-v2-2/
