Raise the pods-per-core limit #2

Open nmasse-itix opened 6 years ago

nmasse-itix commented 6 years ago

On a 8 cores server, the 80 pods limit is a bit low.

The pods-per-core limit should be raised on install:

In the /etc/origin/node/node-config.yaml:

kubeletArguments:
  node-labels:
  - region=infra
  pods-per-core:
  - "20"

Documentation: https://docs.openshift.com/container-platform/3.5/admin_guide/manage_nodes.html#admin-guide-max-pods-per-node

And make sure the max-pods limit does not become the bottleneck also (default: 250)
