If the variables are exposed via Environment you can try using

kubectl describe po env_pod | grep -A 10 Environment                                                        
    Environment:
      DB_URL:                       x.x.x.x
      LC_TIMEOUT:                   10
      SNS_QUEUE_REGION:             us-west-2
    Mounts:
      /var/log from shared-log-storage (rw)
      ```
