volumes-from should be added to service ui soon. volumes-from is available during “Add container”, but is missed during add an service container. Would be great to manage services with data-only containers / persistent storage.
We’re in the middle of re-designing the UI of our applications tab based on feedback from our Beta program. We’ll be adding in this ability when that is released.
You can define data-only containers as sidekicks. Managing them will be in the UI eventually, but volumes-from a service still doesn’t make sense for the same reason I said before.
