Should I clean past instances of an app?

Hi,

While trying to figure out why my healthchecks were failing (I found why :wink:), I ran into the command fly status all while scanning the documentation and got:

I have several questions:

  1. Should I be concerned that v11 is running?
  2. Can I clean the old deployment? At least the v3 and v5 that failed? Should I?

I verified in nomad that the alloc with v11 has been destroyed as expected. That output is nothing to be concerned about. We might have had an operational issue or something like that, which prevented our graphql backend from capturing the final state of that alloc when it was destroyed.

The actual nomad allocs (i.e., the virtual machines) associated with those older version are all destroyed. We keep a historical record of them in our graphql backend, which is what you are seeing with that command. I don’t think there is a way to delete those records (except for deleting the app) and you should not need to.
