SIMULATION
Create a new ServiceAccount named backend-sa in the existing namespace default, which has the
capability to list the pods inside the namespace default.
Create a new Pod named backend-pod in the namespace default, mount the newly created sa
backend-sa to the pod, and Verify that the pod is able to list pods.
Ensure that the Pod is running.
Answer: See the
Explanation below:
Explanation:
A service account provides an identity for processes that run in a Pod.
When you (a human) access the cluster (for example, using kubectl), you are authenticated by the
apiserver as a particular User Account (currently this is usually admin, unless your cluster
administrator has customized your cluster). Processes in containers inside pods can also contact the
apiserver. When they do, they are authenticated as a particular Service Account (for
example, default).
When you create a pod, if you do not specify a service account, it is automatically assigned
the default service account in the same namespace. If you get the raw json or yaml for a pod you
have created (for example, kubectl get pods/<podname> -o yaml), you can see
the spec.serviceAccountName field has been automatically set.
You can access the API from inside a pod using automatically mounted service account credentials, as
described in Accessing the Cluster. The API permissions of the service account depend on
the authorization plugin and policy in use.
In version 1.6+, you can opt out of automounting API credentials for a service account by
setting automountServiceAccountToken: false on the service account:
apiVersion: v1
kind: ServiceAccount
metadata:
name: build-robot
automountServiceAccountToken: false
...
In version 1.6+, you can also opt out of automounting API credentials for a particular pod:
apiVersion: v1
kind: Pod
metadata:
name: my-pod
