If, when doing something like docker-compose up, you run into an error like this:
ERROR: Named volume "server/db:/usr/share/nginx/html/db:rw" is used in service "web" but no declaration was found in the volumes section.
You're missing a leading ./, so, for example:
volumes:
- 'server/db:/usr/share/nginx/html/db'should read
volumes:
- './server/db:/usr/share/nginx/html/db'This example assumes that you want to map a host directory ./server/db/ to a container directory /usr/share/nginx/html/db, not create a named volume server/db.
No its not, if you add ./ to leading then docker will create new directory on the context, so it will be completely new volume and diffrent from that named volume.
you should simply add this section to the compose file
`
volumes:
volume-name-here:
