nginx config for docker registry. The key setting is `client_max_body_size 600M;` which allows large uploads. The setting `proxy_read_timeout 900;` gives the upload enough time to complete (but this might not be needed).

docker_registry.conf

upstream docker_registry {
  server 127.0.0.1:15000;
}

server {
    listen   443;

    root /dev/null;
    index index.html index.htm;

    server_name localhost.localdomain;
    server_name registry.baremetal.io;

    ssl on;
    ssl_certificate /etc/ssl/baremetal/registry.baremetal.io.crt.pem;
    ssl_certificate_key /etc/ssl/baremetal/registry.baremetal.io.key.pem;

    client_max_body_size 600M;

    gzip             on;
    gzip_min_length  1000;
    gzip_proxied     expired no-cache no-store private auth;
    gzip_types       application/json application/xml text/plain text/html;

    location / {
        proxy_pass  http://docker_registry;
        proxy_set_header Host $http_host;
        proxy_read_timeout 900;
    }
}

Thanks, the proxy_read_timeout 900 was extremely helpful for me. Have you considered submitting a documentation / example nginx.conf pull request to the docker_registry guys?

Helpful still today, took me a while to figure out what was going on.
