Docker compose not mounting volumes
Just setup docker toolbox in Windows 10 and I am having a little issue with my docker containers. When I do docker-compose up, the instance will start but nothing is mounted in my /var/www/html directory. If I open Kitematic I see the container and when I click on volumes I do not see the local folder set. Here is what my docker-compose.yml looks like.
web: build: . ports: - "80:80" volumes: - app/:/var/www/html/
Do I need to specify the absolute path to my local directory? The app directory is in the same folder as the docker-compose.yml file.

In addition to @VonC answer, it’s different when using
docker-compose since the docs mention
You can mount a relative path on the host, which will expand relative
to the directory of the Compose configuration file being used.
Relative paths should always begin with
Do I need to specify the absolute path to my local directory?
Yes. The doc mentions:
host-dircan either be an absolute path or a name value.
- If you supply an absolute path for the
host-dir, Docker bind-mounts to the path you specify.
- If you supply a name, Docker creates a named volume by that name.
In your case,
app/ would be considered as a name, not as a host folder.
