Updated Dockerfile and lighttpd.conf

[mmd-osm]

Dockerfile

• openstreetmap-cgimap binary now statically built
• Enable JSON output
• Multi-stage build for smaller image (1GB -> 120 MB)
• Run cgimap as non-root user (sec)

lighttpd

• Update lighttpd.conf to include all supported endpoints,
• Forward unknown requests to Rails port on port 3000 (reverse proxy)
• Include config example for Dockerfile

[mmd-osm]

Extending docker-compose.yml in openstreetmap/openstreetmap-website#2409 to be used alongside cgimap and lighttpd:

Exposes a working stack on http://localhost:31500 (including cgimap features) and http://localhost:3000 (Rails port only)

Local (relative) directory docker/lighttpd/config contains lighttpd.conf, with adjusted host names:

$HTTP["url"] =~ "^/(?!(dispatch\.map))" {
    proxy.server = ( "" => ( ( "host" => "web", "port" => "3000" ) ) )
}

fastcgi.server = ( ".map" =>
  (( "host"   => "cgimap",
     "port"   => 8000,
     "check-local" => "disable",
  ))
)
