Depending on the setup it can be a pain to get nested containers working sometimes. There is, e.g., Docker In Docker but this often required a privileged host container which is often not provided in CI/CD pipelines.

Which issues/pains with getting nested containers?

I am aware of only a few settings that make a container nestle, or not, whether it is a vm, lxc/lxd type container, etc.
