Thanks for this series for K8s. I followed your video about LXD and now found the K8s series excellent.

Once Again Thanks For Such a Wonderful Tutorial on Namespaces & Contexts.

[kanavpeer]

i would recommend these series must watch, if you are new to kubernetes. Very good explained.

[RK-wkzn]

thanks for clarifying the context part. It was really confusing for me.

Hi Venkat, Hope you are doing good. Nice Video on Namespace, Can you please do the video on Multi-tenancy on baremetal or VM.

[sridharreddypullangari]

I like your way of explanation, please make video on how to connect to remote kubernetes cluster from our local machine using Kubectl.

Thank you.

[AnyRussian]

It is one of the best Kubernetes channels. Thanks

Hi, first off all I want to thank you for your efforts on creating these videos, I am learning alot.
Can you please be so kind and tell me what Linux distribution are you using and which desktop UI is that? Gnome, KDE?

Hi Venkat,
As usual, ultimate video. May I know, in which scenario we need to make use of namespaces in first place? Like u explained, we can create same resource in multiple namespaces, ..but if I am working on a project, when I should be using namespaces? Can't we setup our entire app to be running on single default namespace. Do we really come across a situation, where we might need to create a same resource in different namespaces? Or is it just like environment ex: production, test, uat?

[aayush]

what would be the overall differences (multi cluster, user and namespace enviroment) between namespace and context ??

[omkargawade]

Hey Venkat...I have one question..is it possible that one pod(example. application pod) in one namespace could communicate with other pod (example. database) if yes then how?

Hi Venkat,

I am new to k8s and i was to referred your channel by one of my friend. You are very straight to the point and crisp and clear. Thank you for sharing the knowledge.

I have created contexts and when i switched to different context and try getting the pods list i get this error message " The connection to the server localhost:8080 was refused - did you specify the right host or port?" . Am i doing any thing wrong here. I have just followed your steps exactly for creating namespace and creating context and switching.

Hi venkat, thanks for the video, I have a doubt, can we create multiple namespace under context? Like Development context under that namespaces with test1 test2 as well production context namespace test1 test2 namespace names are same(content under the namespace are different) contexts are different, If I change the context it should show only pods(related development nginx pods) if I changed to production it should show only production nginx pods, will it be possible

[manikandans]

Namespaces can be used for defining environments such production, testing etc?

Hi venkat,
Hope you are doing well, Can different types namespaces talk to each other.?

[saurabhagarwal]

Hi Venkat....hope you are doing good...I have one question....If i create one name space for Developer is Dev and one for Tester is Test.As a admin i can switch context.But how can assign Dev Namespace for Developer and Test for Tester.My cluster is running On KOPS.Thanks

[narendrabhupathiraju]

im using minikube, and I created new context and connected to that context, when im trying to kubectl get pods it asks for password, how can I resolve that

[RajKumar-blyd]

Hi, is it possible to create ingress reference service in different namespace

[waterkingdom]

Good video on Kubernetes Namespaces. One quick clarification, what if I want to switch between the Clusters? How will a sample config file look like?

[cavemanble]

If I wanted a user in demo only to have access to the demo context, and not get a result from kubectl get pods -n default, how would I achieve that?
