This blog post is a small cheat sheet, how to log in to an IBM Cloud Red Hat OpenShift cluster using the IBM Cloud and the OpenShift CLI. I’am using information that is provided by the official IBM Cloud documentation.
- Log in to the IBM Cloud
ibmcloud login [-sso]
- Get the cluster configuration as admin
ibmcloud oc cluster config -c my-redhat-openshift-cluster --admin
- Get the master URL for the cluster
ibmcloud oc cluster get -c my-redhat-openshift-cluster
Example output:
Retrieving cluster my-redhat-openshift-cluster...
OK
Name: my-redhat-openshift-cluster
ID: c62jh5lf05XXXXXXX
State: normal
Status: All Workers Normal
Created: 2021-11-05 XX:XX:46 +0100 (1 week ago)
Resource Group ID: 5d662c897a344XXXXXXX

Ingress Status: healthy
Ingress Message: All Ingress components are healthy
Public Service Endpoint URL: https://XXXX.eu-de.containers.cloud.ibm.com:30XXX
Private Service Endpoint URL: https:/XXXX.private.eu-de.containers.cloud.ibm.com:30XXX
Pull Secrets: enabled in the default namespace
VPCs: r010-d724a1ed-XXXXXX
Master

State: deployed
Health: normal
Version: 4.8.14_1531_openshift
Location: Frankfurt
URL: https://XXXX.eu-de.containers.cloud.ibm.com:30XXX
- Get an IBM Cloud passcode by opening following URL in a browser
https://iam.cloud.ibm.com/identity/passcode
- Now log in to the cluster using the passcode and the master URL
oc login -u passcode -p GXIXXXXX --server=https://XXXXX.eu-de.containers.cloud.ibm.com:30XXX
Example output:
Login successful.
You have access to 66 projects, the list has been suppressed. You can list all projects with 'oc projects'
Using project "default".
I hope this was useful for you and let’s see what’s next?
Greetings,
