How to properly configure persistent volumes on dokku with rails?

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/images or any other location like /var/www/app_name/public/images:/app/public/images

On 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.

Note that as of Dokku 0.5.0, we now have a persistent storage plugin built-in.
