For the bare metal provider, ensure that the machine being deleted is not a
Ceph Monitor. If it is, migrate the Ceph Monitor to keep the odd number
quorum of Ceph Monitors after the machine deletion. For details, see
Migrate a Ceph Monitor before machine replacement.
Log in to the Container Cloud web UI with the m:kaas:namespace@operator or
m:kaas:namespace@writer permissions.
Click the More action icon in the last column of the machine
you want to delete and select Delete.
Select from the following options:
Since Cluster releases 17.0.0, 16.0.0, 14.1.0
Select the machine deletion method:
Graceful
Recommended. The machine will be prepared for deletion with all
workloads safely evacuated. Using this option, you can cancel the
deletion before the corresponding node is removed from Docker Swarm.
Unsafe
Not recommended. The machine will be deleted without any
preparation.
Forced
Not recommended. The machine will be deleted with no
guarantee of resources cleanup. Therefore, Mirantis recommends
trying Graceful or Unsafe option first.
If machine deletion fails, you can reduce the deletion policy
restrictions and try another method but in the following order only:
Graceful > Unsafe > Forced.
Before Cluster releases 17.0.0, 16.0.0, 14.1.0
Confirm the deletion.
Deleting a machine automatically frees up the resources allocated to this
machine.
