Linux – Running two http servers, but binding to different interfaces

Both apache and nginx take arguments for which addresses to listen on; if you want apache on 192.168.1.100 and nginx on 192.168.1.110, you would add the following to the respective conf files:

httpd.conf (or /etc/apache/ports.conf, depending on distro):

listen 192.168.1.100:80

nginx.conf:

server {
    # port to listen on. Can also be set to an IP:PORT
    listen 192.168.1.110:80;
    . . . 

You need some type of service discovery for nginx to be able to "find" the containers running on the nodes. You could write a record into etcd when container starts and remove on exit and have nginx check those.

For moving services around, you could take a look at fleet for simple scheduling.
