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=2and see something like
...
name: my-deployment
...
- replicas: 1
+ replicas: 2
...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.
