Openshift 3 : My node can’t spaw more than 40 pods, why ?
If you deploy a lot of pods on each nodes, you might faced to an ressource error. Openshift 3 have a limits set on how many pods can be run on a node by default ?
The answer is yes, by default the limits is 40 pods per node. It can be to low for some usage so i recommend you to increase to 100.
How can i increase the limit ?
On each nodes you have to edit node-config.yaml and add the kubeletArguments section with thoses params :
and of course restart your openshift-node service.
It is possible to use ansible for that
