The Default Service Account

Every namespace has a default service account. If you don't specify a different service account for a pod within a namespace, it will automatically use the default service account for API access and resource interactions.

Step 1: List Service Accounts in Default Namespace

kubectl get sa
kubectl get serviceaccount
kubectl get serviceaccounts

You'll see a service account named default.

Step 2: Create a Namespace and Verify the Default Service Account

Now, let's create a namespace called dev and list service accounts in that namespace:

# Create namespace dev
kubectl create ns dev

# List service accounts in dev namespace
kubectl get sa -n dev

You'll see a service account named default in the dev namespace.

Clean Up

Delete the dev namespace we created:

kubectl delete ns dev
