}

Graylog deployed on self-managed (brought up with kubespray) with similar vaules file has the correct labelled pods with only one master node. self-managed elasticsearch is used.

Also the ELB is net set to SSL and the cert is not associated (after deploy, I have to manaually perform setup)

The multiple master issue is resolved by setting graylog.init.kubectlVersion
