Need help with EX280 exam

Jump to solution

Hi all,

Today was my first attempt at EX280 which I, unfortunately, did not clear.

I failed by a close margin and haven't given up yet.

I noticed something which led to my downfall in the exam:

  • There are no deployments to work with, there're only pods and there's one with a name ${pod-name}-deploy (example: oranges-deploy [completed], oranges-x124 [running])which shows the status as completed. I am super confused as to how I can scale the app, autoscale, set env variables, routes, setting service accounts, etc. if there is no deployment given how can I perform those tasks?

I think I should use deploymentconfigs to perform those tasks.

But the doubt still remains.

Edit: Passed it! Yes, dc was the answer.

Hi, @Supreeth-B 

What about creating deployment from that pod so after you can scale, auto-scale and etc.?

As per OpenShift documentation, "however, it is recommended to use Deployment objects unless you need a specific feature or behavior provided by DeploymentConfig objects."

https://docs.openshift.com/container-platform/4.8/applications/deployments/what-deployments-are.html

DeploymentConfig was not covered in DO280 training. Any reason that DeploymentConfig is used/tested?

thanks.

There are several features which was not covered in DO280 but may appear on exam.

I know it exactly. For example taints/tolerations  - search this forum with "ex280" keyword.
Also self-signed certifs - they are written in exam objectives.
Why deploymentconfigs used instead of deployments - I think exam was created in old times when deploymentconfigs were used and still didn't edited.

I think it's better don't rely on RH courses if they recommend modern forms or resources - you should know both forms - modern and previous versions and be ready to use them (for exam).
