I woke this morning and started running and decided to go back to my studying again. I actually already wrote something down but due to I restarted and had it in my tmp dir I lost my writing. I will startover. That’s life. Keep on going. I start with chapter 4 and going through the overview. Hopefully I can finish its labs this weekend.

The overview went over the following core components of Kubernetes:

Yesterday I failed to write something to my blog. But I wanted to add that I started working with dev containers. And I kind of like it. I still have to learn more about it. Or rather just use it a bit more. For my use case I’m using it for my Angular project. So in this case I have a Angular json file as well. Yesterday I failed to write something to my blog. The way it works I see is that you have a directory which inside is also lets say where you would put your out put in. So it looks something like this:

Another day, another study day.

Just finish watching a live session with techworld nana yesterday. It was about promoting her bootcamp. Look interesting though. Well let me get back to where i’m still working on and that is the LFS258. Today I’ll will be working on acces the application that is running in the cluster from outside the cluster: I will go through some commands that might be usefull for later reference.

Today I’m continueing to go through the journey of writing again. This time I will write my experience off learning for my CKA exam.

What I learned this morning:

• Getting formiliar with the –dry-run flag

  • Essentially this just give you the output without all the unique information printed it out to stdout.
  • Somethink like this would look like:
  kubectl create deployment two --image=nginx --dry-run=client -o yaml

  • It is in fact a simulation of the command without doing anything

• Similar to just printing out a yaml file with the cat command you can also get its information with the -o yaml option:

Now I will just ramble a little bit, I will talk about something else, thinking, thinking, blah blah blah blah, and something else.

Today started to report on my progress on the LFS258. I’m learning for the CKA exam. I started with my 4th lab. And this time I’m using my own raspberry cluster instead. Before I was just using the provided lab environments. I learned about using the deployment command for creating and getting deployments. I learned about putting it in yaml files. And sanitizing the file again for later usage. I’m half way of this lab. And probably will continue next Thursday
