When we downsize or upsize a cluster, does it also redeploy all the apps?

Hi,

I have a question, I’ve deployed an AWS EKS cluster with Qovery. I wanted to know if when we downsize or upsize a cluster, does it also redeploy all the apps?

Thank you.

Hi,

This is an excellent question. When you change your cluster node type with Qovery. We operate a rolling change of all your nodes. So eventually, all your apps are redeployed.

How to avoid downtime?

However, even if all your apps are redeployed, there is a way to avoid getting downtime. You need to:

  1. Set the minimum number of instances to 2 for your apps

  2. Configure the readiness and liveness probes

You need to adjust the readiness_probe.type and liveness_probe.type depending on the protocol type you expose to properly check it. Read our documentation.
