Start host openvswitch using systemctl

Signed-off-by: Michael Cambria [email protected]

Hi @mccv1r0. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

          set -euo pipefail
+          set -x
+          if [[ -f /usr/bin/id ]]; then


-x for executable?

I don't understand all these checks, they are not atomic and thus worse than redundant because they hid the real error message.

/usr/bin/id openvswitch || true

or no || true with the set -e

or I guess it's not clear in which environment id is not present?

I don't understand all these checks, they are not atomic and thus worse than redundant because they hid the real error message.

Most (if not all) of these checks were added to debug and will not exist in the final PR.

+          fi
+          if [[ -d /run/openvswitch ]]; then
+            ls -al /run/openvswitch


ls -al /run/openvswitch/ || true trailing / forces treating it as a directory.

I guess question here as well, when is /var/run not a symlink to /run ?

can we get this PR rebased, wanted to test this with openshift/machine-config-operator#1636?

runcom · 2020-06-16T09:11:11Z

@sinnykumari I think this is rebased now but not sure about all these failures in CI

+            echo "OVS started by ovs-node container, NOT RHCOS"
+          # Need container up v0.0 just to see if host starts ovs and friends


Can you fix the indentation here?

+            systemctl is-active openvswitch
+            journalctl -xeu openvswitch --no-pager


Probably just want to exec journalctl -f -u openvswitch ovsdb-server and be done with the script.

sinnykumari · 2020-06-16T09:36:24Z

@sinnykumari I think this is rebased now but not sure about all these failures in CI

Can it because we would need openshift/machine-config-operator#1636 merged first so that ovn related services are enabled on host to keep cluster install progressing further?

Yikes. This needs to be moved to the "non-systemd case"

This is all debug code

not the kill -9...

I don't really understand why we need to start OVS from this container. Shouldn't systemd OVS be configured as a service with restart=Always? Why does a pod need to start it?

This might have been left-over from before the MCO was going to start OVS. Our first pass was starting system OVS from a pod via systemctl without MCO, but we moved to MCO because Clayton told us to.
