Chapter 3. Getting your cluster ID
When providing information to Red Hat Support, it is helpful to provide the unique identifier of your cluster. For MicroShift, you can get your cluster ID manually by using the OpenShift CLI (oc) or by retrieving the ID from a file.
A cluster ID is created only after the MicroShift service runs for the first time after installation.
3.1. Getting the cluster ID of a running cluster
Use either the of the following steps to get the ID of a running cluster.
Procedure

Get the ID of a running cluster by retrieving it from the
cluster-idfile by entering the following command:$ sudo cat /var/lib/microshift/cluster-id
Example output
7cf13853-68f4-454e-8f5c-1af748cbfb1a
3.2. Getting the cluster ID of a stopped cluster
For a cluster that ran before, but is not running now, you can get the cluster ID from the cluster-id file in the /var/lib/microshift directory.
Procedure
Get the ID of a stopped cluster by retrieving it from the
cluster-idfile by entering the following command:$ sudo cat /var/lib/microshift/cluster-id
Example output
7cf13853-68f4-454e-8f5c-1af748cbfb1a
