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.

    Just to add to this, don’t add this option to the build phase (at least in Dokku 0.3.22) it will fail with rm: cannot remove ‘/app/public/images’: Device or resource busy error while pushing or rebuilding, and won’t launch the app.

    Handy functions to check that it’s correctly set up are:

    • sudo docker ps
    • sudo docker inspect (app_image_NAME)

    The bottom of the json object will have the following values:

    "Volumes": {
    "/app/public/images/projects/images": "/home/dokku/uploads/katz"
},
"VolumesRW": {
    "/app/public/images/projects/images": true
}

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