Failed create pod sandbox: rpc error: code = Unknown desc = NetworkPlugin cni failed to set up pod "test-hunt-microservice-3-rpdqh_test-test" network: CNI request failed with status 400: 'failed to run IPAM for 065credacted96redacted31ce42c91878: failed to run CNI IPAM ADD: failed to allocate for range 0: no IP addresses available in range set: 10.128.0.1-10.128.1.254 '

possible reasons

  1. node running out of ipaddress

  2. cleanup of ips for dead pods is not properly done. (may be bug in older ocp versions)

    debugging

check for timestamps here ls -l /var/lib/cni/networks/openshift-sdn/

Drain the node:

oc adm drain $node
systemctl stop atomic-openshift-node
rm -rf /var/lib/cni/networks/openshift-sdn/*
systemctl start atomic-openshift-node
oc adm uncordon $node

Also check https://github.com/cloudnativelabs/kube-router/issues/383. There is a (automatic) workaround using https://github.com/jsenon/api-cni-cleanup.

Is there a built-in solution for this issue in Openshift 4 ? I have this issue in Openshift 4.7.
