deck gateway diff

The diff command is similar to a dry run of the deck gateway sync command.

It loads entities from Kong and performs a diff with the entities in local files. This allows you to see the entities that will be created, updated, or deleted.

deck gateway diff is the replacement for deck diff.

In deck gateway diff, the following has changed:

• Files changed to positional arguments without the -s/--state flag
• The default write location changed from kong.yaml to - (stdin/stdout)
