Any way in kubernetes to first deploy a new pod with a new version, then take down the updated pod and add the one we created in advance to the statefulset ?When some pod gets recreated during rolling update it can take a lot of time and the app can be unavailable since it needs quorum for example.

I’m having trouble understanding your question. I think you’re asking how to deploy your app without downtime. Is that correct? – Nick Rak Aug 08 '18 at 11:53

Yes, say I have 3 nodes in my cluster - each with 1 pod - >If I could start a 4th pod "on the side" and switch to it I would save myself the starting time of the upgraded pod – Mika R Aug 08 '18 at 20:03
