For e.g i want to install OCP 4.3.18

On  top of what environment are you trying to install? as far as I know you do not specify the version in

install-config.yaml, it is the RHCOS images you downloaded and used for installation, look at the ignition file and check which RHCOS release is referenced?

Hi Walid,

I am deploying on Azure using IPI. Actually Red Hat support engineer asked this question

Please confirm which OCP you are installing OCP 4.3.0 or OCP 4.3.8

in your install directory, there will be a log file ".openshift_install.log" that has the version as part of the log. mine had something like "time="2020-05-10T19:23:48+03:00" level=debug msg="OpenShift Installer 4.4.3""

If it was a UPI install, check in the ignition file to determine the version by which version RHCOS is refernced

May be you can check the openshift-install tool for which version you tried to download also

./openshift-install version
openshift-install 4.4.3

Hi Walid,

Yes i can check the installer version but i need to know that this 4.3.18(in my case) installer is installing which OCP version.

How can i get that info?

it is by default installing 4.3.18 unless you have upgraded the cluster. What state is the cluster in? what files do you have available and accessible? do you have the openshift_install.log file? or can you do export KUBECONFIG=auth/kubeconfig if the api is up? and then you can use the whole shebang of oc commands against the cluster
