How to label pods?

[kirreen]

FEATURE REQUEST (?)

How can I label the mysql-pods? Is it possible to achieve from the mysqlcluster-resource?

Hi @gites @kirreen, currently we apply a couple of labels in the operator but don't expose a mechanism for setting custom labels via the MySQLCluster custom resource. Would you mind expanding on your use case and we can see about implementing?

It would be nice to have custom labels, for example, to define pod affinity or antiaffinity.

Hi @marcogiacomassi, MySQLCluster has an affinity field for this purpose: .spec.affinity. It's not documented anywhere though which we should fix.

@kirreen does that solve your use-case too?

[kirreen]

No, my use case is a NetworkPolicy.

@kirreen Ah right. We should add a .spec.podLabels to MySQLCluster that we propagate down to the StatefulSet's Pod template.

Some Docs on this would still be nice... BR B
