Very good video Than you Sir..

[@galeop]

14:47 has this role been assigned to my pod thanks to a K8s RoleBinding (and thus is this the same thing as "K8s roles for RBAC"?), or is this just a label? In other words, are K8s roles only used for the access to the Kube API (eg API request to get the value of a K8s secret, list pods, etc), or are they also used as criteria for K8s Network Policies (like it seems to be the case in 14:47 ) ?

[@manasjain914]

I wish this channel should get millions of subs

[@cloudwithraj]

Ty Manas for the kind words. Best of luck in your career journey!

[@natallia1109]

Videos are amazing .......

Thanks Natallia, I am glad you found my videos useful.

Cloud computing is future for deployment of system and OS. Reliable and easy to use.

[@padmadasp599]

Good 👍

[@tanejavinay2000]

Good coverage. I have two questions 1- when you say you can borrow IPs of other subnet, how is that borrowed ip from other subnet be given access to resources which were accessible to borrowing subnet in network policy 2- how do we control what kubelet and kubeproxy agents can do, how to apply network policy on those agents that they shoun not be able to access DB, considering those are not developed by me

[@mitchellm6549]

Thanks!

[@cloudwithraj]

TY Mitchell for the generous tip. I am glad this video was helpful 👊

[@shamikguharay3177]

Thank you

[@cloudwithraj]

Welcome!

[@rohanekar]

Can you posible to create one video to create a Mysql microservice in Kubernetes and access this SQL using SQL workbench, or any solution I need to look?.

[@sanjibsaha2229]

great content just like all your video. Question on Ingress & Egress Network policy - How it can be set at cluster level so that admin can only modify not individual app team for their PODs hosted from different namespaces

[@cloudwithraj]

Currently it can't be cluster level, can only be applied to pod level. however you can use OPA to enforce that each pod has network policy

[@dineshkumarlanka5470]

Thank you Sir...Very great video on Network, can you share few more....

[@cloudwithraj]

Thanks Dinesh, will do more on Networking in future for sure

[@hackerops1407]

Sir can you make video on how real time kubernetics environment look like what is the project flow how the services application deployment are worked.

[@googleuser5076]

Can you make a video about Multus and its importance compared to other meta plugins,please

[@kannanswaminathan8210]

can you talk about 1. having private cluster, 2. How to use kubectl from local desktop to control the cloud k8s, 3. How to build a tool that is hosted as webapi to run kubectl or kubernetes client sdk and how to access the k8s using kubeconfig or any alternate is there to access the k8s from webapi.

[@vinayakchandrakantnawale3529]

Very nice video one question here can we use both calico and pod security group together in eks

[@cloudwithraj]

Unfortunately currently it's not supported to run both together. I am hoping for an enhancement in future since they both serve unique and different purposes.

[@vinayakchandrakantnawale3529]

@@cloudwithraj Thank you for quick response

[@ShirishShukla7776]

Pod security group - if you can cover in detailed

[@manabdas6923]

Hi Rajdeep da, your college junior again. Could you please make a video on Operators (say for DB hosting PODs/stateful PODs) ?

[@cloudwithraj]

CHeck this out Manab - kzbin.info/www/bejne/onmmaKume8aWoZo

[@k.r.mohanreddyk.r2350]

How to get each pod have get unique ip

[@cloudwithraj]

Hmm? Each pod already gets a unique IP

[@k.r.mohanreddyk.r2350]

Where to get which one sharing

[@cloudwithraj]

@@k.r.mohanreddyk.r2350 kubectl describe pods will give you the Pod IP.

[@k.r.mohanreddyk.r2350]

I know describe the pod ip but my doubt automatically allocated ip right, which one sharing like kernel or any other one
