I've run out of ideas as to why I can't connect to this nginx inside or outside of the docker. I can understand that networking might cause a problem outside the machine, but even inside the docker nginx is not responding even though you can see it running and listening (inside the docker). Outside the docker, maybe the port isn't mapping thru but it seems to be configured such that it should.
"Config": {
"Hostname": "",
"Domainname": "",
"User": "",
"AttachStdin": false,
"AttachStdout": false,
"AttachStderr": false,
"ExposedPorts": {
"80/tcp": {}
},
On the HOST machine
root@host:~# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0be6e751cd6d humanyze/nginx:config-pentest "nginx -g 'daemon of…" 8 seconds ago Up 8 seconds 80/tcp inspiring_boyd

root@host:~# netstat -an | grep LISTEN

And even though nginx is not installed on the host, this still shows up
root@host:~# ps ax | grep nginx

And inside the docker
root@host:~# docker exec -it 0be6e751cd6d sh
