find which yaml file was used for the any kubernetes resource?

How to find, that which yaml file was used for the deployment of any kubernetes resource.

I checked "kubectl describe", it doesn't list the same, is there anyway to know.

use case:

I want to update the yaml and redeploy, one option, I guess is to generate the yaml from running resource, update and redeploy.

any suggestions ?

Solution

  • To get yaml for your k8s application deployment.

    Use this

    kubectl get deploy my-deployment -o yaml --export
 OR
kubectl get pod my-pod -o yaml --export
 OR
kubectl get svc my-svc -o yaml --export

    Editing is also simple.

    kubectl get deploy my-deployment -o yaml --export > my-deployment.yml
<Edit the my-deployment.yml file and kubectl apply -f my-deployment.yml>

OR 

kubectl edit deployment my-deployment

    Hope this helps.
