I am doing the Do180 comprehensive review and I can see the RHT_OCP4_QUAY_USER in the /usr/local/etc/ocp4.config file. But when I try to push the nexus image to Quay getting an error
Any idea how to fix please?
I have a feeling that your login to quay might've not been as successful as the output suggests. Because generally speaking the syntax of your commands looks alright (though I'm used to doing a push based only the targetname, without also specifying the source label).
Could you run:
After source command , do a podman login and then try to run the podman push command and see if it is working or not.
If it is still not working then do one thing: delete your existing lab and create a fresh one and then start with lab-configure and then redo the steps as I suggested.
If it does not work for you at all - please open a support case.
