Hi, We had the same problem, I am not sure but it looks like the pod number is not such important for scheduler, and sometimes we ended up with nodes with 40 pods and other with 1~2. Setting limits and request values on CPU and memory in deployment configs generally fixed that for us.

Our pods don't have any node selectors so all nodes are available to all pods. What we are seeing is the scheduler constantly placing pods on nodes that are already heavily usitised (in terms of memory and/or cpu) while other nodes have plenty of capacity. We have places resource request on some pods and they continue to be placed on the busy nodes. How can we help the scheduler make better decisions? -bash-4.2$ oc version oc v3.6.0+c4dd4cf kubernetes v1.6.1+5115d708d7 features: Basic-Auth GSSAPI Kerberos SPNEGO openshift v3.6.173.0.21 kubernetes v1.6.1+5115d708d7 Thanks This message (including any attachments) may contain confidential, proprietary, privileged and/or private information.
