Troubleshoot cluster resizing

This page shows you how to resolve issues with resizing clusters.

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:

 Events:
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.
