A few months back, Jason Braganza pointed me to this podcast episode from Cal Newport.

Each question asked during this particular podcast was very helpful to me. I literally got answers, solutions, work-arounds, frameworks (or whatever you wanna call them) to solve my own set of problems at the time.

Today, I want to put here, (kind of) a gist of an answer to one of the questions asked...

(Earlier, the title of this blog was ~ (I’m struggling for a title) notes!)

I’m struggling for a title(s), for these daily blogs. If you’ve any suggestions, please please tell me 😅 (I’m very serious). I want to entirely eliminate this title thinking part.

Anyways, updates from today:

• Today was kind of a leisure day. Well, kind of only, because for the whole day, I was troubling my-own-self with the feeling...

• Another thing, I need to...

Today was a so so day. I would say, the last some hours were hard, other than that it was wonderful in the morning. I did more than usual productive stuff during the time.

(see, I myself am confused, that’s why it was hard. Just too much overthinking happening. 😅).

Well, I didn’t feel like writing today. But then times like these become the culprit behind me breaking a good going streak....

Same as yesterday, I spent most of my day continuing with the Red Hat OpenShift Administration I (DO280) virtual instructor led training (VILT). It’s going wonderful. :)

The topics from today’s class were around configuring OpenShift networking for applications.

• I learnt how OpenShift exposes the conatiner applications to external networks using ingress & routes. I learnt about different types of routes (secure & unsecure) that could be created under the OpenShift...

This week, I’m working on Red Hat OpenShift Administration I (DO280) virtual instructor led training (VILT). This training is a preparatory course for the OpenShift Administration Certification Exam (EX280).

During one of the chapters today, around troubleshooting OpenShift clusters, I came across this command oc debug node/<node-name>, which is used for debugging cluster nodes (kubelets, crio-d containers, control-plane stuff etc). This command provides a way to...
