Quick way to print environment variables of a running pod

A quick post to showcase how to print environment variables of a running pod.

A quick way to print the environment variables of a running pod is to use the following command.

kubectl exec <pod-name> -- env

For example, take a look at the sample nginx pod with few additional (MY_POD and PORT) environment variables.

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
  - image: nginx:1.14.2
    name: nginx
    ports:
    - containerPort: 8080
    env:
    - name: POD_NAME
      value: "my_pod"
    - name: PORT
      value: "8080"

Once the pod is in running state, you can use the following command to print the environment variables of the pod.

kubectl exec my-pod -- env

You can see the output as below listing the environment variables.
