Deployment issues

Hi @GrahamDumpleton,

When I deploy in my single-node cluster, I get the error:

`

12:54:00 PM	my-notebook-2-zmcps	Pod	Warning	Failed Scheduling	0/1 nodes are available: 1 Insufficient pods.20 times in the last 4 minutes

`

Any ideas?

There is a limit on the number of pods that can be scheduled to nodes in a cluster. This is dictated by amount of resources (based on CPU cores by default I believe) nodes have. The error indicates that the number of pods attempting to be scheduled to the node has exceeded that limit. This limit is a system configuration value, so only your cluster admins can do anything about it. In short, it generally indicates the system believes it is overloaded.

Thanks! I'm also running OpenWhisk on @gshipley 's single node OpenShift Origin instance for demo purposes, so I assume that is the issue.

P.S. Thank you also for signing a copy of your book at Summit! @GrahamDumpleton @gshipley

Closing this as assuming nothing to be done.
