RBAC in Kubernetes

So far we have accessed everything from our Kubernetes cluster without any restrictions. But in real time, we’ll have multiple nodes, namespaces, deployments, replica sets, pods, services, and many other Kubernetes resources. Also, we will have many users accessing these cluster resources. When we don’t have any restrictions, there may be chances of deleting these resources accidentally.
So, it’s wise to impose restrictions to create, modify, and delete resources based on some role. For example, we should ensure that developers can only deploy certain apps to a given namespace or that our infrastructure management teams have read-only access for monitoring tasks, and the admin can do everything. In this chapter, we’ll be learning how to restrict access to Kubernetes resources using the RBAC framework with complete hands-on.

Mr. Pavan, your explanation was quite good but you could be more specific about what you do in the YAML file which you tend to skip that is biggest thing in kubernetes to understand. Make sure that you add it in your upcoming videos.
Don't take me wrong :))
This is awesome

Pavan, it's really awesome Thanks for the video. I have one doubt If i want to grant the same user permissions across multiple namespaces without using a ClusterRole is it possible or not ?
Hey Pavan, Great Explanation.
I have a question -> are these steps same for all other process - kops, AKS, EKS ?
Yes Santhosh
OMG ...... Amazing...... ❤️
really helpful..
Hi Pavan,
Thanks for the video, have you tried kube bench to check rbac compliance?
Thank you so much Viswa. Heard of it, but never tried. Please subscribe and share with your friends and colleagues
Hi Pavan, do you know where I can get the ca.key and ca.crt in eks cluster 1.26
Hi Pavan, Great Explanations❤
But I have a doubt, If user pavan can switch between context then he can switch to minikube context and start performing admin task right ? then how can we make sure he can login using his certs and can only see his related context ?
so when workig with actual clusters, where do i get that ca.crt file which you used for user creation?
You download it from somewhere?
If you have deployed your cluster using kubeadm then use the path -CA /etc/kubernetes/pki/ca.crt -CAkey /etc/kubernetes/pki/ca.key
Dont you need to create csr request on the cluster ??
Great Explanation
one doubt
When there are 40 users and some of them have different permissions
Then I should repeat the same steps 40 times or is there an any other way ?
You can use groups
Doubt!, where we are creating a user , is that Linux user or Iam user from AWS or kubernetes supports to create a user ???
My k8s applications always uses , psp as restricted . So it always restricts pcap capture inside pods .
I see netadmin rawnet capabilities alllows
How do I provide permissions to capture pcap in my pods and enable from my helm charts
can we have the commands shared in git hub link please the openSSL ones
I have installed ubuntu desktop on a virtual machine and there i have configured 3 node minikube cluster.
i have created a demouser on ubuntu desktop. how i will assign a cluster role to demouser so that when i login to ubuntu desktop as demouser it should have readonly access to pod resources.
Bro if the user have the acces for the cluster nodes he have acess for kube admin , he have the ablity for changing all files and edite it , he can creat all users and etc , how to over come these these is possiblity to remove the admin user,
Hello, in the sa part, you listed pods inside a pod? I'm a little confused about what happened here.
the pod is created using kubectl image and that has kubectl command inside the pod. so trying to access pods inside the pod (pod is a function user / batch user / non-human user) to access the resources. Hence we need a service account which has to be attached in role binding with roles. Hope its clear
Plz bring live project..
Hi, can you please help? I am using microk8s and facing issues in creating csr and cert. Please help! TIA
But i created kubernetes cluster using kops so in That scenario how can i do this can you please do video on that by creating kubernetes production cluster using kops
Noted!
Bhaiyaa please cover helm topic please
Hi Abar Syed. Sure!
I face error You must be logged into sever (unauthorized) after kubectl get pods . I think I followed you all steps.
May I know your openssl version?
@@PavanElthepu 2.8.3
Try upgrading it to latest version, delete minikube cluster and start fresh. It should work
I tried many ways and I still face same problem 😢
Tried with 3.6.1 version?
nice 👍👍👍👍
