The Red Hat Learning Subscription is such a great tool, I have learned so much this past year by having it.
Even though I have used a lot of the Red Hat products at work , going through the courses on the RHLS has made more proficient at using them.
For example, I've been using Ansible for a while now, and I am terrible about remembering all the options for each module. I would always go Google'ing for them. After spending a few days studying for the 407 exam I learned that you just have run ansible-doc <module-name> and it will give a "man page" of that module. I wish I knew when I first starting using Ansible. =)
So, what did you learn today?
More and more learning and exploring. Today I learned how easy and convenient ReaR is and how much of a headache it aleviates. Its developers can't be thanked enough.
Hi Jason ! Cool thread by the way ! :)
What I have learnt today is the OpenShift equivalent of your "ansible-doc <module-name>" (which I love too, especially with the -s flag !) ;)
It's: oc explain
It gives a desciption of all possible properties of any OpenShift object. You can also get down the hierarchy of any object, like :
$ oc explain scc.supplementalGroups.ranges
I'm going to use that a lot ! Especially for Red Hat exams :D
That's a great one! There are a lot of pieces and parts to OpenShift, trying to memorizing everything would be impossible. That command will definitely help out on an exam.
This is good thread!
I learned advanced usage of Ansible filters to convert a nested list to a flat one alongside the usage of filter attributes to only retrieve what I need :D
