How to properly configure persistent volumes on dokku/rails?
I have apps running nicely with dokku and ruby on rails. But in every deployment my uploaded files are deleted.
What is the best way to configure the correct path (“public/images” folder of rails) that I don’t want destroy after deploy?
I’m running (without success so far):
dokku docker-options:add app_name run "-v /home/uploads/app_name:/home/dokku/app_name/public/images"
dokku docker-options:add app_name deploy "-v /home/uploads/app_name:/home/dokku/app_name/public/images"

I’ve found the solution.
Just replace the path with
/home/uploads/app_name:/app/public/imagesor any other location like/var/www/app_name/public/images:/app/public/imagesOn the left side (
/var/www/app_name/public/images) is the path where dokku will save files on the system.On the right (
/app/public/images) indicates which folder (inside rails app) will be saved from.https://github.com/dyson/dokku-persistent-storage/issues/1
Note that as of Dokku 0.5.0, we now have a persistent storage plugin built-in.
