Today we're going to look at simplifying YAML management with a tool called Kustomize.
Kustomize is built into the kubectl binary, making it super easy to access and consume as part of your operations and CI/CD pipelines.
Many times, especially for microservices we want a simple solution.
Kustomize provides that simplicity without over complicated templating.

This is actually the best Kustomize tutorial on youtube hands down. Easy example, straight to the point with overlays and patching. Please keep up the great work !

4:53 - Yes yes yes, this 100%. I’ve only been working with k8s for a relative short while, but I found myself really over complicating things once I realized how much simpler it was to use Kustomize to accomplish the same thing. It’s all about _simplifying_ and making the code easier to *reason * with. I realized that the little trade offs (e.g. less verbosity) resulted in major downsides in other areas like incorporating too much logic and too many variables, layering of variables (defaults), for loops and worse, the use of parameters to incorporate dynamic values at template generation time _dramatically_ increased the cognitive load required to reason about what was ultimately happening. Once I stumbled upon Kustomize I started to realize a completely new way of thinking about how to solve these problems which resulted in a much simpler solution that may have had _slightly_ more code, but that code wasn’t harder to refactor. Best of all: It was just much easier to understand and I was _much_ more quickly able to add, edit, change things with less resistance.

You're a legend. Thank you for this! This tutorial is so clear and perfectly focused on the topic! The added value of sharing your repo is saving a lot of time and makes it easier to learn. One thing I am missing is the agenda - it would be awesome if you could add timestamps for your video in the description or the video itself, it would make it easier to return to this outstanding tutorial and go through some of the stuff again. Either way, you're the top of the game. Thank you once more for this clear explanation! I subscribed after first few minutes of the video, obviously! Cheers!

Thank you very much. Your video is very informative and useful. I'm going to apply Kustomize to the project at work. I have been struggling to find a smooth approach to handle different environments (dev, testing, staging, prod, etc.). The pains include image tag replacing, persistent volume / persistent volume claim. Take PV and PVC for example, I use Docker Kubernetes on Windows, on local dev environment, I cannot specify static PV paths and can only use PVC with automatic storage allocation, but on staging and prod, I must use PV with nodeAffinity. So on. You know... I think this is a great find. Thank you!

@anonymoususer6448
@anonymoususer6448 3 года назад
I apologize if this sounds like nit-picking... I'm merely trying to be helpful :-) aAsimple fix, to correct any pre-recorded talk, could be to not switching the entire view to where you are sitting behind your computer, but leave your bash on the screen, freeze the screen, correct the audio and during that talk just blank the insert with yourself ... This results in a lot less screen swapping which gives our (my) eyes a lot more time to adjust and assimilate the contents. Also many of the Zooms are unnecessary...it is extra work for you and it makes me having stop the video everytime for a second or 2 just to be able to assimilate the contents (may my eyes are slow to adjust)

Could you do a full Consul on k8s video? There are loads of examples out there for this, but most start with, “install helm,” which I very much don’t want to do. I had this running at one time but as I’m very new to Kubernetes I ended up blowing it away a few nights ago. The most promising bit of information out there results in nothing being deployed; 2 instances just get marked pending. :/ Your videos are very useful and I would welcome a namespaced consul deployment from you! And sidecars; I’m very unclear about sidecars. All I wanted to do there was monitor my Kubernetes Postgres instance. :/

@tonyjoanes
@tonyjoanes 3 года назад
Something I'm thinking here is that if you want developers to easily setup their development environment which would be multiple Kubernetes resources from different repositories then Helm would make it easy to install everything they need rather than having to checkout each repo and deploy it (using helm registry)

Thank you for such a great explanation. Questions, Does Kustomize deletes stale configmaps from the cluster ? What are your thoughts on using a tool like "Stakater" for configmap and secret reloads ? Thanks again.
@MarcelDempers
@MarcelDempers 3 года назад
Kubernetes does not delete state configmaps. Thanks for sharing, Stakater looks like a very cool utility 💪🏽
@stevebrayshaw7228

Can you use kustomise to alter a base deployment via an override to add in the init container etc for vault integration ? I’m thinking about the use case where a vendor deployment uses basic secrets that I then want to change it yo integrate with hashicorp vault. Great presentation style btw.
