OpenStack known issues

This section lists the OpenStack known issues with workarounds for the Mirantis OpenStack for Kubernetes release 21.6.


[6912] Octavia load balancers may not work properly with DVR

When Neutron is deployed in the DVR mode, Octavia load balancers may not work correctly. The symptoms include both failure to properly balance traffic and failure to perform an amphora failover.


[16495] Failure to reschedule OpenStack deployment pods after a node recovery

Kubernetes does not reschedule OpenStack deployment pods after a node recovery.

As a workaround, delete all pods of the deployment:

for i in $(kubectl -n openstack get deployments |grep -v NAME | awk '{print $1}');
do
kubectl -n openstack rollout restart deployment/$i;
done

Once done, the pods will respawn automatically.


[18713] Inability to remove a Glance image after an unsuccessful instance spawn

When image signature verification is enabled and the signature is incorrect on the image, it is impossible to remove a Glance image right after an unsuccessful instance spawn attempt. As a workaround, wait for at least one minute before trying to remove the image.


[19274] Horizon container missing proxy variables

Horizon container is missing proxy variables. As a result, it is not possible to create a Heat stack by specifying the Heat template as a URL link. As a workaround, use a different upload method and specify the file from a local folder.
