var-run is consumed by config-job for nicMappings etc. So the config job never exits because: Need to reconcile with it. Maybe we don't need a config-job and can squash it into the same statefulset somehow?.. |
This allows to get rid of a hostMount shared between the job pod and the main ovsdb-server pod container (to enable communication of vsctl command with the database socket). Getting rid of hostMounts is needed to be able to eventually stop running ovn-controller pods as privileged containers.
This is to prove that this is possible, now that configJob is squashed into the main ovn-controller pod.
We log to stdout. Nothing else is needed.
This directory can be local to the container and does not need to persist. Note the rundir directory is not present in the image, so we have to switch OVN_RUNDIR to point to /tmp, same as we do for other ovn services managed by the operator.
I am not aware of anything using the directory.

Some of the volumes can be cleaned up with no bad effect. But at least the volume that passes over the ovsdb-server AF_UNIX socket to configJob via a file cannot be removed until we switch this communication channel to AF_INET sockets. This is technically possible but requires significant work to e.g. deploy SSL certificates for the channel. This PR may still be useful, but I should drop the removal of the socket volume from it first before we can proceed with a partial volume list cleanup. |

These seem unnecessary; and they block our progress on moving from HostPaths to e.g. PVCs, which would allow us to disable privileged mode (/home hostPaths seems to carry selinux labels that are not available for the containers.)
