Docker volume not working with Nginx

Question

I've created a simple Docker container with Nginx inside and for some reason, it won't access the www volume data from the host.

Here is the command I used:

docker run \
    -d \
    -p 8080:80 \
    --name nginx \
    --restart always \
    -v /etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro \
    -v /var/www:/usr/share/nginx/html \
    -v /home/myuser/myvhost.conf:/etc/nginx/sites-enabled/myvhost.conf:ro \
    -v /var/log/nginx:/var/log/nginx \
    nginx:1.9.4;

All the volumes are correctly mounted (I checked with docker inspect) but when go on the website I get a 404 and the Nginx error.log on the host says:

"/var/www/docker/index.html" is not found (2: No such file or directory)

It's surprising because this path is definitely correct...

Answer 1

Nginx is looking for content in /var/www, and you don't appear to be mounting anything on /var/www.

You are mounting your host's /var/www on /usr/share/nginx/html inside the container.

It looks like you either need to (a) modify your ngingx configuration, or (b) mount your hosts's /var/www inside the container as /var/www, or (c) you have some of your -v specifications backwards (the syntax is -v <host_path>:<container_path>)
