Entry point for nginx deployment

I have docked nginx which works fine if I start the shell, but (naturally enough) if I give "start nginx" myself as an entry point, it just unmounts and exits immediately due to no pending process.

My inclination is to do something like this:

pid=$(cat /run/nginx.pid)
while ps ax | awk '{print $1}' | grep -q $pid; do
    sleep 60
done

      

        
        
        
      

    

Although this seems pretty hacky. But when I use Google for the example, I see people running bash.

Any pointers?
