Using symbolic links
Using the public folder
If it’s acceptable to serve your files from your public directory, you can re-use the public/system folder which is already automatically symlinked to shared/system on each server.
The downside of doing this is that it bypasses your application and your files get served directly by Nginx without security.
Adding symbolic links
Alternatively, you can use deploy hooks to create the symbolic link.
You can use $STACK_BASE for your application base path (eg. $STACK_BASE/shared/uploads) for your deploy hook script.
To create the symbolic link, your deploy hook script could contain this:
mkdir -p $STACK_BASE/shared/uploads
chown nginx:app_writers $STACK_BASE/shared/uploads
rm -rf $STACK_PATH/uploads
ln -nsf $STACK_BASE/shared/uploads $STACK_PATH/uploads
The reason we are runninng rm -rf on the $STACK_PATH/uploads directory is due to the way that the ln command works. When you issue the ln command, it places a link to the source directory inside the target directory, so we have to remove the directory before creating the symbolic link.
Save the script as a .sh file and add it to your repo. The resulting deploy hook would look like this:
production:
after_symlink:
- source: /.cloud66/my_symlink.sh
destination: /tmp/my_symlink.sh
target: docker
execute: true
sudo: true
apply_during: all
run_on: all_servers
