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 ?
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 --exportEditing 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-deploymentHope this helps.
I think you can choose here from two options.
Option 1:
You can grep all YAMLs looking for specific annotations or labels.
$ grep "app: nginx-test" *.yamlor
$ grep -e "prometheus.io/scheme: http" *.yamlWhen you find proper file you can edit it (vi, nano, etc) and apply.
$ kubectl apply -f [yaml-name]Option 2:
When you know name of your deployment you can edit it.
$ kubectl edit deployment [deployment-name]You will see current deployment YAML with a status: section which describing current status of deployment. If you don't like vi, you can use nano instead
$ KUBE_EDITOR="nano" kubectl edit [deployment-name]If you want to create YAML from your current deployment I would advise you to use kubectl edit with --export flag. It will removes unneeded information (like status: from previous comment).
$ kubectl get deploy [your-deployment] -oyaml --export >> newDeployment.yamlHope it will help.
