Description: Is it possible to delete an app via Spinnaker? If so how?

[anotherchrisberry]

@aglover what are the restrictions we want in place w/r/t deleting an application? anything? just no server groups?

[aglover]

Is it possible for us to clean up everything associated w/an Application? As in, you confirm deletion, we'll wipe out ASGs, ELBs, security groups, etc?

It would be very cool if when you delete an Application (and all of its bits), it doesn't actually delete it, but instead schedules it for deletion. So maybe it no longer takes traffic, but the actual resources don't get killed off for a day or something.

@aglover I'm not sure how much we can do there. We can delete ASGs, and probably delete security groups, and probably ELBs.

It would have to be orca-strated. The current 'delete application' functionality provided by gate simply deletes the record in front50.

@duftler I like that idea - especially if we're blowing up the world, maybe disable server groups, then schedule a deletion event in 24 hours.

How about we just show the user the things that are keeping us from deleting the app so that they can clean them up. I don't like deleting things en masse that are related to an app.

[aglover]

@claymccoy I think asking a user to delete a bunch of other things is a lot of work -- I like the idea of letting them know what will be deleted and then doing it. When someone actively says delete my app then they shouldn't be surprised that this means that ASGs, etc are going to be blown away. Just like when you delete a repo in Github, it doesn't ask you to 1st delete the branches, etc -- it just warns you that this cannot be undone and asks to you confirm.

[aglover]

This is done: https://github.com/spinnaker/gate/blob/master/gate-manual/src/asciidoc/deleteApplicationStage.adoc ... Need it surfaced in the UI (https://github.com/spinnaker/deck/issues/129)

Awesome. Thanks.
