See exact manifest diff for `kubectl scale` before executing

Is there any way to see what is going to exactly happen when I do kubectl scale ... before I actually run the command?

I would like to do something like:

kubectl scale --dry-run --diff ...my-deployment --replicas=2

and see something like 

...
    name: my-deployment
...
-     replicas: 1
+     replicas: 2
...
Solution

  • Straightforward answer is it's not possible.

    I don't know your intention, but if you can use option --current-replicas in some cases.

    --current-replicas=-1: Precondition for current size. Requires that the current size of the resource match this value in order to scale.
