The kubernetes dashboard allows one to see secrets in plain text (not base64 encoded) and make an easy change to any key-value pair within a Secret. I cannot find a way to easily make a similar change on the command line.
My best attempt has been to write a script which uses kubectl get secret to pull all of the data in Json format, grab each key-value pair, base64 decode the values, update the one I actually want, then feed them all back in to kubectl apply. After running into multiple issues I figured there is probably a kubectl option that I'm overlooking which will allow me to update just one key-value pair in a given Secret.
How can I do this?
Usually you would have your secrets manifest stashed somewhere where it is secure.
I dont usually change the secrets using the dashboard, but instead do a kubectl apply -f mysecret.yaml. the mysecret.yaml file keeps the latest and greatest values. No in-place editing. This way you get consistency across deployments.
