If commands do not seem to work, it is because when they were copied, they included the '>' inadvertently on the next line. Remove the '>' beginning the second line and the command will work.

@nyan-nyan That's nice catch !

Can you please help to understand any specific reasons for not updating this course to later versions of openshift. If not, how can we get hands-on for later versions of Openshift installation lab

[aqutu_oscuro]

I want to know the reason too. OCP will soon be 4.20+, the course is stuck at 4.6, surely many things have changed. 

[Chetan_Tiwary_]

@aqutu_oscuro yes the versions have changed since then. The course development generally gives more priority to courses which are more popular or more in demand and also based upon the development planning. I will try to get an update from the curriculum team about possible updates to this course but I am pretty sure it will take time and is not expected anytime soon.

HI @kishorech816 ,

is 10.244.1x.3x  your ingress or API VIP? 

What is your machine network? 

If possible share the install-config.yaml file.
