I don’t remember anyone else ever asking this, and I don’t see an obvious way. I think your best bet is do to a
./launcher destroy app
if you want it to stay stopped and start it again with
./launcher start app
This will destroy the container, so any changes you’ve made inside it (like upgrades from docker_manager) will be destroyed.
Oh, but here’s this:
tl;dr: do a docker update --restart=unless-stopped app after each rebuild.
