[ Kube 86 ] Getting started with Kustomize tool for Kubernetes

[@javisartdesign]

great! kubernetes has decided to deprecate kustomize within kubedam in favour to patches. "In Kubernetes 1.16, #1177 Advanced configurations with kubeadm (using Kustomize) was introduced to allow patching base configurations and obtaining configuration variants. For example, you can have a base configuration for your service, then patch it with different limits for each of your dev, test, and prod environments. The kubeadm team has now decided to use raw patches instead, in a similar way kubectl does. This avoids adding a complex dependency like Kustomize. For this, a new flag --experimental-patches has been added, mirroring the existing --experimental-kustomize, and once the feature reaches Beta, it will be renamed to --patches. "

Hi Javier, thats very helpful. I am going to pin this comment. Many thanks.

[@Gandolfof]

Wow! The way you create initial yaml files using dry-run was amazing!

[@justmeandopensource]

Hi Hossein, thanks for watching. Yeah good to know some shortcuts.

[@rubbercable]

A good solid delivery: steady pace, no-bloat-words, clear description Might I recommend: - a better camera, lighting increase image size bt 25% - audio (room has echos, better mic and bigger room) - increase font by 125%

[@justmeandopensource]

Hi, thanks for your suggestions. Much appreciated. I need to research more on my recording setup. At the same time I don't want to concentrate too much on that but stick to the content. I am not doing a full view of myself. Its always the screen that is the main content and I am just showing myself so that you know who am i. Mic is certainly one of the best (Blue Yeti). May be its the format or the rendering time processing that makes it worse. Increasing font is definitely something I need to remember to do every time. Cheers.

[@rubbercable]

@@justmeandopensource BlueYeti is definitely awesome. In that case, it may be the echo/acoustics in the room.

[@justmeandopensource]

@@rubbercable Yeah its the room unfortunately.

nice video @Venkat. By seeing simple examples we could understand the purpose and power of kustomize. like to see gitops framework with flux cd if possible soon. :)

Hi Jaya, thanks for watching. I will do more videos as time permits. cheers.

Thanks for this great video. Kustomize makes a lot more sense to me now. Now I need to figure out how I can apply it :) Btw, what ksh theme are you using? I love the little arrow from the dir name to the command input line.

[@justmeandopensource]

Hi Xander, thanks for watching. I used Zsh with some plugins in this video. I have done a video on my terminal setup a while ago. kzbin.info/www/bejne/hoa6n3aYp56WhJo

Nice tutorial. I see that nobody asked yet, so I'll do it. What's the name of the promt terminal that you are using, it looks awesome.

Hi Victor, thanks for watching. Its a comination of these * termite - terminal emulator * zsh - shell * oh-my-zsh - zsh plugin manager * zsh-autosuggestions - zsh plugin to suggest commands from my zsh history * zsh-syntax-highlighting - zsh plugin for syntax highlighting * powerlevel10k - Prompt customizations

Hi Venkat, thanks for watching. I use Arch Linux with I3 Tiling Window Manager - Zsh shell - oh-my-zsh (zsh plugin manager) - zsh-autosuggestions (plugin that suggests commands based on my history) - zsh-syntax-highlighting (plugin) I am also planning to do a video on my latest terminal setup as many users requested. Here is the one I did a while ago. kzbin.info/www/bejne/qaCkqIinZ8iEfrM

Nice one :) One off-topic question is, can you tell me how to enable that feature to show bash command autocomplete or full command suggestions on the Terminal transparently when you start typing?.

I am building a new project on EKS and can't decide if I should use kustomize or helm, which one would you recommend?

[@prajulchauhan]

@VenkatNagappan Hi Venkat, I have a request on a urgent basis. Could you please make a video on how to use vagrants on windows 10? how to connect those vagrants with VS Code so that we can use IDE's for better development on & if we have multiple vagrants how can we connect them? like if we have a master node & a webserver for some ansible playbook. I would really appreciate it if you could just do a small video on this.

[@yogithakakarla1716]

Wherr do we find this code ? Any github repo ?

[@justmeandopensource]

Hey, thanks for watching. Link to kustomize github repo is in the video description.

[@rekhas4063]

Hi Will Argo cd pulls code other than yaml files like any config file or any scripts

[@shazone4141]

Why not helm chart?

[@justmeandopensource]

What do you mean?

[@shazone4141]

@@justmeandopensource we can use helm chart for same kind of job.

[@justmeandopensource]

Yes ofcourse. Very similar. Helm is complex compared to kustomize. Moreover Kustomize is a templating free yaml generator.

[@michael.h984]

Sometimes understanding Kustomize is necessary. For example, if you need to manage FluxCD.

[@vibhormathpal2021]

Thanks for such a great content.. I have one query, when i am applying (kubectl apply -f overlay/dev/ ) first time it goes fine and i see all the labels as expected, However when i update the (overlay/dev/kustomization.yaml ) with one commonlabels parameter and re-apply ((kubectl apply -f overlay/dev/) ,it throws error instead of restarting pod and adding label to it.. Please see the error {[k8s@k8s-worker-2 demo]$ kubectl apply -k overlay/dev/ The Deployment "dev-nginx" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app":"nginx", "owner":"vibhor"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable }
