Not using --cache-from, though I did try the various caching command line options to try to troubleshoot. Just a vanilla Dockerfile with a few RUN commands and COPY commands. It would hit cache until about the third layer, and then would cache break every time. On my local computer (Arch) podman is v2.1.1, which seems to have whatever bug I was hitting fixed. So I guess my complaint isn't about podman specifically-- It had bugs and they were fixed, and that's great. But I hate that RHEL 8 touts it as a docker replacement, and won't carry docker in their repositories, when the version they have in their production releases is so broken. We eventually sledgehammered docker CE's CentOS repo into our RHEL 8 jenkins server and now everything works perfectly. Running podman on the production webservers seems to work okay though-- apart from the process killing problems.
