If you were running a Toolforge web tool in Kubernetes before the toollabs-webservice
label changes were deployed on 2021-09-29 (
https://sal.toolforge.org/tools?d=2021-09-29
<https://sal.toolforge.org/tools?d=2021-09-29>). You may need to run `webservice
stop && webservice start` in order to ensure your replica sets have correct label
expectations on them going forward. Otherwise you may find confusing states may happen
when running webservice restart and similar commands.
When I backfilled the new labels, I missed that you cannot change the label matching rules
in a deployment retroactively. I apologize for any inconvenience.
In summary: If you haven’t run a webservice stop since 2021-09-29 on your Kubernetes web
service, it would be a good idea to stop and start your webservice now to prevent any
confusing behavior from webservice in the future.
