Resizing a user cluster fails

If a resizing of a user cluster fails, complete the following steps:

  1. Find the names of the MachineDeployments and the Machines:

    kubectl --kubeconfig USER_CLUSTER_KUBECONFIG get machinedeployments --all-namespaces
    kubectl --kubeconfig USER_CLUSTER_KUBECONFIG get machines --all-namespaces
  2. Describe a MachineDeployment to view its logs:

    kubectl --kubeconfig USER_CLUSTER_KUBECONFIG describe machinedeployment MACHINE_DEPLOYMENT_NAME
  3. Check for errors on newly-created Machines:

    kubectl --kubeconfig USER_CLUSTER_KUBECONFIG describe machine MACHINE_NAME

No addresses can be allocated for cluster resize

This issue occurs if there are not enough IP addresses available to resize a user cluster.

kubectl describe machine displays the following error:

Type     Reason  Age                From                    Message
----     ------  ----               ----                    -------
Warning  Failed  9s (x13 over 56s)  machineipam-controller  ipam: no addresses can be allocated

To resolve this issue, Allocate more IP addresses for the cluster. Then, delete the affected Machine:

kubectl --kubeconfig USER_CLUSTER_KUBECONFIG delete machine MACHINE_NAME

Google Distributed Cloud creates a new Machine and assigns it one of the newly available IP addresses.
