I tested with bbernhard/signal-cli-rest-api:0.100-rootless finally it worked as expected even running all the stuff in Kubernetes, but while troubleshooting I found out, this it is not possible to add -v to the signal-cli command, which gives useful logs if doing silly things.
e.g.:
2026-06-18T23:40:06.561Z [Thread-21] INFO LibSignalService - [LibSignalChatConnection]: [normal:1795803621] connection unexpectedly closed
org.signal.libsignal.net.ConnectedElsewhereException: the server explicitly disconnected us because we connected elsewhere with the same credentials
I am unsure if it is a rootless thing or not, but I have not found a way to set -v except overwriting the entrypoint and exec into the container and run signal-cli manually
