We have created deployments which in turns creates pod. I need to get the Pod names created by my deployment file.

kubectl get -f deployment.yml

The above command list the deployment names. If i type kubectl get pod it displays the pod names which is having some random extra strings added with deployment names.

Even if i use the -o json option still unable to get the pod names.

How to get all the pods created by deployment? Even a shell script way would be fine.

my deployment file looks below

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    ansible: test-2020-05-26-00-04-1590476651
    podRef: pod-ansibles
  name: rd-2020-05-26-00-04-1590476651
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: nginx
        ...
        ....

so is there any way that i can get all pods which has deployment label 'test-2020-05-26-00-04-1590476651' ?

when i tried 'kubectl get pod -l ansible=test-2020-05-26-00-04-1590476651' . it shows

'No resources found in default namespace.' seems it can only display deploy name 'kubectl get deploy -l ansible=test-2020-05-26-00-04-1590476651'

But i need all pod names which is under a deployment..

Usually, we label deployment's pods.

  template:
    metadata:
      labels:
        app: my-app

So, we can get all pod filter by label

kubectl get pod -l app=my-app
