What did you learn today?

[varelov]

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

[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  

[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.
