I know you can't run mailman commands in the docker images and I have to copy the data to an area where he docker images can access it, but in looking that the commands I got the list settings to import
docker exec -it mailman-core mailman import21 [REDACTED]@REDACTED].REDACTED].org /opt/mailman/migration/config.pck *** this worked
But having issues importing the archives? do i run this on mailman-core OR mailman-web? I tried both but it does not like python?
docker exec -it mailman-core python manage.py hyperkitty_import -l [REDACTED]@REDACTED].REDACTED].org /opt/mailman/migration/[REDACTED].mbox OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "python": executable file not found in $PATH: unknown
