centos 8 is dead. need to use centos 8 stream now. the stream images are hosted on quay.io, not dockerhub https://quay.io/repository/centos/centos?tab=tags&tag=stream8
Quay is the best place to build, store, and distribute your containers. Public repositories are always free.

If you use CentOS 8, you might have noticed that starting from January 31, 2022, installing packges with yum no longer works with an error…
