[ Kube 43.2 ] Getting started with KinD | Local multi-node k8s cluster in Docker containers

[@VishwaSeneviratne]

This guy is the best. He is doing an amazing job teaching us these.... Thank you very much for doing these...

[@justmeandopensource]

Hi Vishwa, thanks for your interest in this channel. Cheers.

[@thepetesmith]

Amazing vid! I am just starting to use KinD and WSL-2 as a development platform for a large k8s project. Our goal is to allow teams to only develop their service but leverage the others that they don't work on in an easy local setup. Any clues or tools for this need most welcome ! Thanks! The first thing I hit was the need for a simple local persistent volume for development purposes.

[@justmeandopensource]

Hi Pete, thanks for watching. I remember watching a video demo of a tool that exactly meets what you want. Develop a service locally while integrating other dependent services from a different environment. The project is Telepresence. www.telepresence.io/ I haven't used it myself to be able to comment.

[@pankajbhatt5010]

This is pure gold. Amazed by the knowledge and the world of tutorials he has.. OMG.... food for 100 days at least.

This video inspired me to use a 2nd cluster to my main app cluster... the 2nd cluster would be a little service environment that would do things to the main cluster.

[@justmeandopensource]

Glad to hear that. Thanks for watching.

[@david_devdev9558]

ha for info i have tested Minikube too. More functionnlities. I didn't choose it because kind lighter with docker only ... except now .. minkube can be used with a simple docker container too ! minikube start --driver=docker !

[@justmeandopensource]

Hi David, thanks for watching. Cheers.

[@BanibrataDutta]

Yet another great video. Thanks for sharing your vast knowledge. Would be very nice if you could consider a video covering usage of PodSecurityPolicies, SecurityContexts, multi network-attachment as well.

[@justmeandopensource]

Hi Banibrata, thanks for watching. I have a huge list of topics to cover. Struggling to find time lately. And these ones you mentioned are in my list. I will see if I can get back to these. Cheers.

Nice Video series !! It would be great if also publish a video of deployment of full fledged Autogpt on k8s cluster or kind cluster. Even nice to have one video with deployment of Milvus Cloud native vector database in k8s cluster.

Imagine I have 7 virtual machines (VMWare) and I want to host 3 master nodes and 3 worker nodes and 1 load balancer. How do I configure this setup?

Hi Venkat, When I reboot my VM, kind kube cluster is not coming up. I am sure you have some solution for this issue. Can you please help me with that.

I am getting docker image pull error in docker desktop, using wsl even image pull policy never is not working

[@charank7852]

Hi thanks for video on KinD. After i created the kind cluster i cant see the config file under .kube under my home folder. But i am able to access the cluster. What am i missing here ? how can i find out the config file for my kind cluster ?

[@justmeandopensource]

Hi, thanks for watching. I just checked and after I ran kind create cluster, I was able to see ~/.kube directory created and I can see the config file in there. You may be checking in the wrong host. Check on the host where you are running kind create cluster command. You may have ssh'd into a remote machine where you run kind and ignorantly checking your local machine for .kube/config. Hope it makes sense. Cheers.

[@charank7852]

@@justmeandopensource Thanks for reply. I am using kind version 0.17.0 and i am using ubuntu 20.04 desktop as my personal computer. I have checked /home/charan directory where i cant even see .kube folder also. What am i missing here ? kindly help

[@justmeandopensource]

@@charank7852 That's strange. Can't think of anything that would cause this. How did you confirm that there is no /home/charan/.kube directory? I believe you know how to see hidden directories.

[@charank7852]

[@TheRed662]

When you want to use MetalLB with mutli-node kind, how should we turn off the default HaProxy?

[@justmeandopensource]

Hi Prashanth, thanks for watching. I would just leave the default haproxy to do its job in this multi-master kind setup and still use metallb. They are not replacement for one another. Metallb is for cluster load balancing.

[@TheRed662]

@@justmeandopensource Thank you for clarifying! I have one other issue - following your steps verbatim is not letting me access the nginx url thru' metallb. I'm using macos and docker desktop. Should I be doing port forwarding? I didn't have success on my first attempt but will try again

[@SmaranRai]

Hey ! I am a beginner. I was following the tutorial but when I ran this command, I am getting an error. I think I have followed the tutorial without missing a step. Can you please help. >docker exec -it kind-external-load-balancer sh OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown I also tried bash but it gave the same error. The funny thing is, the sh is available in the other nodes - masters and workers, its just the load balancer that i cant get access to using sh. Can somebody please explain me why is this happening and how can i solve it.

[@justmeandopensource]

Hi, thanks for watching this video. Did you see me running this command in this video? If so can you point me to exact time in this video. I can then take a look.

[@SmaranRai]

Hey thank you for replying, yes I was following your tutorial. It is on 17.21 timeframe. I can't access the load balancer using sh.

[@justmeandopensource]

@@SmaranRai Thanks for getting back. I just tried the whole setup on my Mac and I am seeing the same error as you. The kind-external-load-balancer container created by kind tool uses the kind/haproxy container image. The kind/haproxy:20200708 image used in this video was two years old. The one you get now is the latest which is kind/haproxy:20230606 version. Things might have changed. The base image used on this container image might have changed. I was just showing the haproxy process inside the container. There is no need to get shell access to this container. May be thats the reason they have removed shell access to this container.

[@SmaranRai]

[@KHIMLALSHARMA]

Hi Venkat Nice video, But I've one question Can we create kind cluster in Docker host networking other than default bridge netwoking or can we install metallb with different subnet other than worker node subnet ? If you could please answer of these would be helpful to hunt on this.

[@rikschaaf]

Would it be possible to use kind to run a multi-node cluster across multiple PCs?

[@burakg3371]

hello how to install kubernetes in offline environment?

[@justmeandopensource]

Well you could build an internal repository server for rpm based or debian based servers depending on what OS you are going to use for kubernetes nodes. And then during the installation you can point to that internal mirror server for pulling kubernetes packages. The problem is all the kubernetes container images are hosted in gcr repository and you have to make sure you got all those images locally in your internal environment. The easiest way would be to set up a proxy machine that has internet access and allow all kubernetes nodes to use the proxy during the installation.
