What did you learn today?

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?

Learning every day. For example, today I learned how big of a heartbreak TigerVNC really is.

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.

@varelov this is great - whats resources/tools are you using the most when learning? Labs, courses, tutorials?

I recently learned Puppet and passed the configuration management exam! (EX405)

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

[jthiatt]

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 

[jthiatt]

That's a good one, sounds like you are doing some complex stuff!

I am learning to respect YAML as my playbooks are riddled with formatting errors  after identifying the correct modules and variable structures for a play.

I found out about ShellCheck. Bash scripting will never be the same again.
