Increase default max pods per node

#1

Hi all, on GKE there is a cluster wide setting called “Default maximum pods per node”, that is set to 110. Does anyone know if it’s possible to increase this, without migrating to a new cluster ?

AFAIK, you can override the cluster wide default with nodepool configuration. We actually lower the number in our pools due to CIDR limit we have.

Also, I have found that once more than 80 pods are scheduled on a single node, things get quite unresponsive for our stuff.

Okay so it’s because of maximum number of ip’s in the range. Then i have to migrate or split my pods up on smaller nodes instead of few big ones.

Thanks.
