I spoke with Eric and he explained that this could be the desired UX for a
majority of the apps pushed with --no-route. There are more advanced
deployment strategies that might set --no-route and bind to routes later,
but I think we can expect these users to be explicit with their health
check as well. I think my discomfort with this arose when you mentioned to
me that we might want to do this in the Cloud Controller. As long as this
continues to be explicit from the API perspective, I'm fine with changing
the UX of the CLI per your above proposal.

IMO the healthcheck of the app should be determined independently of
whether a developer wants their app routable.
My understanding of the implications for you proposal are that a developer
could not have a port-based healthcheck without mapping a route. This seems
unnecessarily restrictive. Soon developers will be able to specify http
healthchecks. Would these be prevented also?

I considered this a bit more after we chatted yesterday and I don't think
we should try to create parity between DEAs and Diego in this case. My
personal opinion is that behavior should be explicit and these two flags
provide a more correct experience with the Diego backend.

Hi CLI users,
With apps deployed to DEAs, a health check is performed at application
start-up targeting the app’s port, unless you specified `--no-route`, in
which case the process is monitored.
With Diego, the health check is performed continuously and the type of
check was exposed through an option to the `cf push` command.
This option defaults to `port`, which isn't always appropriate for apps
pushed without a route, such as worker apps.
We propose fixing the `--health-check-type` option’s default value to
align with the behaviour seen for DEAs, i.e. to use “none” if option
`--no-route` is used:
--health-check-type, -u Application health check type (Default:
'none' if '--no-route' is set, otherwise 'port')`
Would anyone object to such change?
