I have been experimenting with creating my own apps/taking existing apps and modifying them. We are a small studio so just trying to find a diy way to make this work. Most apps need just a little tweak to fit with our workflow.
Workflow so far:
created a copy of the pipeline configuration for a project (sandbox)
created an app and placed it to app-store inside the sandbox
-linked the app so it loads on the engine startup
everything works and the app is loading using the sandbox
If I push the sandbox config to Primary it only copies the /config folder. However the app is still linked to the appstore located inside the sandbox.
I just copied the app to the /config folder and linked it to it. It works but I feel like there is a better way.
The way to do it using tank after you pull the config changes: <project path>/tank cache_apps
This will download any referenced apps and engines.
What kind of location descriptor are you using for your apps? dev, path, gitbranch?
There are several ways to go about it. I personally can recommend this workflow where you upload your custom app to SG.
So for development you would either use a path or dev descriptor and once you are ready you switch it out to point to SG. Takes a bit to get used to but is pretty flexible in the end. (The workflow can also be streamlined at a lot of places with some clever scripting) .
Hope that helps
