Hey there, I don’t have experience in Kubernetes production environments but I saw that Kured[1] daemon set can be used for maintenance as well as “kubectl drain” command. Hopefully, this information can be useful.

We are using this approach in our development environments, so anytime developers don’t use their setup they scale it to 0 then bring it back by scale back to 1. Here is more info https://kubernetes.io/docs/reference/kubectl/cheatsheet/#scaling-resources To bring it down kubectl scale --replicas=0 deployments --all -n <namespace> kubectl scale --replicas=0 statefulsets --all -n <namespace> To bring it back up kubectl scale --replicas=1 deployments --all -n <namespace> kubectl scale --replicas=1 statefulsets --all -n <namespace> From: <onap-discuss@lists.onap.org> on behalf of D'Alessandro Alessandro Gerardo <alessandro.dalessan...@telecomitalia.it> Reply-To: "onap-discuss@lists.onap.org" <onap-discuss@lists.onap.org>, "alessandro.dalessan...@telecomitalia.it" <alessandro.dalessan...@telecomitalia.it> Date: Friday, January 25, 2019 at 8:17 AM To: "onap-discuss@lists.onap.org" <onap-discuss@lists.onap.org> Subject: [onap-discuss] procedure to shut down and reboot ONAP/Kubernetes Hi, we need to move our testbed (ONAP/Kubernetes/Openstack) and hence we need to shut it down and boot it …. but we weren't able to find any procedure to do that in a safe way. Few months ago a power outage required us to re-install both Kubernetes and ONAP. Has someone of you already faced with the same problem and can provide some guidelines? thanks in advance. best regards, Alessandro Questo messaggio e i suoi allegati sono indirizzati esclusivamente alle persone indicate.
