Hi,

Pulling the image jgraph/export-server (with podman) fails with this error:

Trying to pull docker.io/jgraph/export-server:latest...

Possibly there is a file with uid:gid that does not fit in my subuid range.

Where can I find the Dockerfile that was used to build this image?

keestux commented 1 year ago

This image is probably created on a system with large uid values. Or the subuid is set too broadly.

I believe it serves no purpose to allow such high uid values. At the same time it hinders podman environments with a default installation (subuid range 65536).

Hi,

I'm not an expert with podman, can you please explain the problem with setting UIDs range high?
