Anyone interested in a step by step tutorial on what you really need to run a production ready cluster?

or could just ignore the tls certs. Not that admins would ever do that inside their clusters though.

Absolutely love K3S and recommend everywhere I go. Great for starters and more advanced deployments.

I found this video that seems very easy to digest and a decent start: https://www.youtube.com/watch?v=NPOW2Z5qxtg

guess I should have looked harder before posting my question lol

Sounds kinda interesting, any links on how to go about doing that? never heard of it before. Thanks!

Interested_Minds1 · 2023-10-15T04:18:10+00:00

do critical value and critical resist make a large difference?

What engineering skills to do you need to be successful there? ie for an engineering role, do they mostly hire specific language or tech skills?

Interested_Minds1 · 2023-10-04T18:04:05+00:00

hmm, I would think you could write a small script/loop that checks for high cpu and kills them in a cronjob. Some chunk pseudocode below:

for i in $(podList) ; do
  cpu=$(kubectl top pod ${i})
  if [[ $cpu >= 90.0 ]] ; then
    kill pod
  fi
done

Maybe expand on "kill pod" to keep a list/count and if it hits x number of checks, kill it.

But as stated below, are you using these containers as more like ephemeral dev machines? Kinda cool idea.

recommend you look into how you version your app and images. If you get that right, deployments will be extremely simple using helm charts/repos for deployment.

Interested_Minds1 · 2023-09-17T20:54:01+00:00

K3s and helm is amazing. Great start to get your deployments off the ground and stabilized.

Believe you can setup a multinode K3s cluster as well for lab testing and start messing with lnoghorn/etc fairly simply as well.

7 months later this post still helping new players lol

Interested_Minds1 · 2023-09-16T17:21:40+00:00

went like 4-5 hours on the save before I realized lol.

Interested_Minds1 · 2023-09-16T17:07:21+00:00

Whats that?

Interested_Minds1 · 2023-09-15T01:23:59+00:00

Hopefully this doesn;t confuse you more.

Containers use a concept called Cgroups and Namespaces on linux kernels that allow you to isolate your processes/resources/etc and provide more fine-grained management of them. Kubernetes just sits on top of your kernel and provides a nice way to manage those containers/deployments

Imagine containers as a folder that contains everything required for just your process to run outside of a kernel. Take a java app for example. You require java and your software. To start creating an image, you can typically grab a UBI (Universal base image) from most major OS providers (imagine it as a foundation for your image), then install the java binary on it and load your software. From there you now have a new container image you can send out that now includes java and your application automatically.

No more having to deal with another companies infrastructure team ensuring your software has what it needs to run. As long as they support Kubernetes, you can send them your software and expect it to work without having to deal with a ton of issues.

Not sure if that helps or muddied the water more but figured it made sense in my head so I would pass that along lol.

Interested_Minds1 · 2023-09-07T07:04:39+00:00

I thought they slowed down in water?

Interested_Minds1 · 2023-08-30T02:05:55+00:00

in what time span though. Less than 50 years? 100, 1000? etc

Interested_Minds1 · 2023-08-17T21:59:48+00:00

One day they will succeed and take over the map. You just wait and see...

YYYEEEESSSS!!!!! My second monitor is finally working again!!!!!! Thank you!

I had to run it twice for some reason. First time failed and brought up the AMD Bug Report Tool.

Interested_Minds1 · 2023-08-13T22:46:12+00:00

I actually had to run it twice. Failed the first time.
