I was wondering, Do you know of a limit on how many rootless conrainers can one run on a linux host?
Running fedora server, I have resources but once I pass about 15 containers podman starts to hang and crash.
I then need to manually delete the storage folder under ~./local/share/... for podman to work again.
It might be related to user ns keep-id flag.
I’m not convinced what you run into is a specific podman issue. It’s a resource issue and configuration issue likely. “vanila” podman with proper rootless containers will run as much workload as machine can handle from my experience. My company costomers seem to be running production workloads with it just fine.
Oh wait, by rootless container you really meant running podman rootless? still don’t see an issue though. What specifically are you doing? I mean, what’s the configuration and what’s the workload?
