Understanding Kubernetes can be difficult or time-consuming. In order to spread knowledges about Cloud technologies I started to create sketchnotes about Kubernetes. I think it could be a good way, more visual, to explain Kubernetes (and others technologies).
We continue the serie of Sketchnotes about Kubernetes with CronJobs.
If you are interested, I published an entire illustrated book about Kubernetes, available in paperback on Amazon and in digital version on GumRoad: "Understanding Kubernetes in a visual way".
As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-).

Does not really show how to create a cron job.
Indeed, I can add how to create a cronjob 😉
Sketchnote improved 😉
Can you tell us why cronjob is used instead of starting manually?
A cronjob can be useful for recurring "jobs".
If you want to run automatically a program which retrieve images and export them in PDF, for example, it's possible in a cronjob.
You can schedule the cronjob.
I mean, why run Kubernetes cronjobs? Why not just start it manually? Is it just to automate some task by invoking a pod?
It's for automated tasks yes.
A cronjob scheduled every 10 minutes, will spawn a new pod every 10 minutes.
If a pod failed, you can watch the logs, analyze and understand why this case has failed.
do you think you can use some font like Consolas or any fixed width font? Makes the command a little more clear:
I didn't find how to change the font in the software I use. I will take a look this evening 😉
👍👍👍 you can also use Google Docs... I wonder if it has Consolas now but I used it before so I still have it in my font list. You can use a Mac and use Monaco or Menlo. Windows has Lucida Sans Typewriter I believe.
I draw my sketchnotes in an Android tablet in an application and then export in jpg/PDF.
So I will check if I can change the font in the software.
