The delay feature of docker is incredibly needed. If I am trying to launch a stack of services using deploy, I want an option for service #2 to wait to spin up until after service #1 has started. In this case by started I mean if I run docker service ls
I want to see that service #1 has 1/1 replicas or whatever I am expecting (not 0/*). This is what I believe the depends on
tag should do, but it doesn’t.
A use example of this would be the following:
I have a service that tests all of my other services that I want to run with my stack and then spin down. But of course all of the services that are being tested need to be up and running before the test service runs itself. This would be immensely useful.
