[CentOS-devel] CentOS/AArch64 image for Docker needs update

Hi

There is 'centos/aarch64' image in hub.docker.com repository. The problem with it is that there is only "latest" tag while one for x86-64 has both "7" and "latest" tags (and several other which I can ignore).

Someone say "so use centos/aarch64:latest instead". But this is not a solution. There are moments when you have to convince some upstream developer that patch like "tag=7;if arch == aarch64 then tag=latest" is crucial for your work.

I do not remember who created previous image (Jim may know) but it would be nice to get them recreated with proper tags.

Some kind of updates would be extras ;D
