It appears that cRPD is not retaining system commit and rollback information after a container redeployment. The persistent volume still exists with the config gzip files, but these are not seen by MGD after container spin up.

Stop/start docker result in the loss of historical commits/rollback options.

Example:

Start system with container id:

root@VM1-Worker-1:~# docker ps

CONTAINER ID       IMAGE              COMMAND                CREATED            STATUS             PORTS                                                                        NAMES

e773f1cc5e78       crpd:22.4R2-S2.6   "/sbin/runit-init.sh"  6 minutes ago      Up 6 minutes       22/tcp, 179/tcp, 830/tcp, 3784/tcp, 4784/tcp, 6784/tcp, 7784/tcp, 50051/tcp  crpd1

Start JUNOS and create a configuration:

root@VM1-Worker-1:~# docker exec -it crpd1 cli

root@crpd1> show version

Hostname: crpd1

Model: cRPD

Junos: 22.4R2-S2.6

cRPD package version : 22.4R2-S2.6 built by builder on 2023-10-05 00:25:00 UTC

Log back into JUNOS. Current config is still loaded but the system commits/rollbacks are missing:

root@VM1-Worker-1:~# docker exec -it crpd1 cli
