VPC: Why can't I create worker nodes on dedicated hosts?

When you try to create worker nodes on dedicated hosts, you see an error message similar to one of the following.

The dedicated hosts for the zone 'eu-de-2' are not ready.
Insufficient dedicated hosts available in zone 'us-south-3'.
Dedicated host has insufficient capacity

The possible causes for these issues include:

  • There are no dedicated hosts in the specified zone or pool.
  • There are not enough dedicated hosts available.
  • There are not enough resources available on the dedicated host.

Complete the following steps to resolve the issue.

  1. List your dedicated host pools and make a note of the pool ID.

    ibmcloud ks dedicated pool ls
    
  2. Lists the hosts in the pool and verify there are available hosts and that placement is enabled.

    ibmcloud ks dedicated host ls --pool POOL
    
  3. If there are available hosts, and placement is enabled, review the details of your dedicated host and verify there are enough resources available to create the worker node.

    ibmcloud ks dedicate host get --host HOST --pool POOL
    

    You can also review your dedicated host resources in the console.
