How can I install Podman in HPC cluster

Feature request description

I want to do experiments on an HPC cluster, but I can't install Podman without sudo, is there any good way to solve this problem?

I am also looking for a way to do this.

The problem is the admin seems to have removed /etc/subuid and /etc/subgid and I don't think there is a way to get around that without asking the admin to change it.

@Zihe33Huang - as far as Podman goes, you could compile it from source locally but even that assumes you have the right packages.

In total, it seems like the initial install is going to have to be done by an admin.

You should use fuse-overlayfs if at all possible, since the performance and disk usage of "vfs" is horrible.

Thank you! I will try it!

You can install it by compiling everything, including dependencies, from source. Using packages is optional, although much more convenient...

But maintaining the subuid tables requires admin support, otherwise you are stuck with one user per container (and "ignore_chown_errors")
