Share volumes between Podman Systemd services

 December 31, 2023

Since the merge of Quadlet in Podman, I’ve been moving multiple services to Podman Systemd services. I find them to be easy to create, manage, and automate.

I recently migrated a complex system to Podman Systemd, where multiple processes write in a folder, and one process reads the folder’s content. Before the migration, everything worked properly since all the processes were running natively on the machine with the same user. After the migration, there were some permissions issues. This issue allowed me to dive a little more deeply into the whole implementation of SELinux for containers and realize a few interesting things.
