Kubernetes Service Account in detail | Service Account tutorial

In this video I talked about what are Kubernetes Service Account resources and how do we can use them in the processes (programs) that are running in Kubernetes, to access Kubernetes API-Server. We also talked about the controllers that are responsible for creating the Service Accounts in every namespace and making sure that the Service Account that is being referred from Pod is actually available. Apart from that we actually looked into the content of the secret that gets create when we create a Service Account, how we can create that secret by our own. There was some confusion at 27:15 where I wanted to confirm if the command that we ran `kubectl get pods` was using the token that was mounted in the pod but in hurry couldn't confirm. Here is how the log looks like ``` kubectl get pods -v 6 I0321 17:57:00.285247 185 merged_client_builder.go:164] Using in-cluster namespace I0321 17:57:00.285372 185 merged_client_builder.go:122] Using in-cluster configuration ``` and using in-cluster configuration simply means that, kubectl is getting authentication details from `/var/run/secrets/kubernetes.io/serviceaccount/` Web: https://viveksingh.dev/ *SA : Service Account 00:00 Introduction 00:18 Agenda 00:27 Users of Kubernetes Cluster 02:18 What are Kubernetes Service Accounts 03:45 Service Account Controllers 04:44 Default Service Account in a Pod and privilege 06:40 Summary of what have been discussed 07:20 Secret that Service Account refers to 08:40 Create a namespace to demo things 09:45 Detailed look into the Service Account's Secret 10:49 What is ca.crt in the SA's Secret 14:30 What is token in the SA's Secret 15:16 Using details from SA's Secret to access API Server 19:10 How SA details are mounted in Pod 21:00 How an application uses the mounted SA 22:50 Access that default SA has 28:36 Name format of SA user 29:29 Don't mount SA token automatically 31:41 Creating SA secret manually 33:05 Creating custom Service Account 35:09 Like and Subscribe
