Add description for containers

[xiaojinghu93]

Hi, all,

We've deployed sregistry in our clusters, of which the software and hardware environments are both quite complex. We'd like to add descriptions to containers to help users/developers grasp infos like the architecture, the version, the compiler and so on.

Currently we have to differentiate the containers by name(with long suffix).

Sregistry's already provided a separate page for each container. It would be nice if the description can be displayed and edited on that page.

Please feel free to close this issue if you are not interested in it. Or if you have better alternatives(better than long suffix), please share it with me.

Thanks in advance!

Yep, can definitely add this! And likely we can store with the container metadata so the database doesn’t need a migration. And you’d be ok with editing the interface to add the description?

mine more suggestion I’ll make in terms of labels is to use org.opencontainers.image.description - it’s currently used by GitHub packages containers for the same goal.

I should have some time to work on this soon.
