I’m pretty new to digital ocean and developed a Go app. The app works by fetching images from sources on the web and store them in a local directory for further serving. The app is working fine in the localhost , but when deployed using dokku , nothing happens. The app cannot seem to find the images.
I searched and found to configure persistent-storage or volume-plugin. I’m confused with this and need help.
Thanks in advance.

Hello, making persistent storage for images (maybe uploads from your users) on DO instance is pretty easy:
- create some folder on the server that will hold files
mkdir -p /opt/dokku/YOUR_APP_NAME/uploads - create/configure your app to store files (uploads) somewhere in the project
PROJECT_ROOT/uploads - setup
docker-optionsfor you appdokku docker-options:add YOUR_APP deploy,run "-v /opt/dokku/YOUR_APP_NAME/uploads:/app/uploads"
That last command made Dokku expose PROJECT_ROOT/uploads folder to be linked to /opt/dokku/YOUR_APP_NAME/uploads on the server. So everytime the application writes something to the PROJECT_ROOT/uploads it will in fact write to the /opt/dokku/YOUR_APP_NAME/uploads outside of the container. That way your files will not be destroyed by next deploy.
