This article describes the configuration of simple load balancing on the Docker, host for the Ubuntu 14.04.2 LTS, two CentOS containers, host installation Nginx, two containers installed TOMCAT7. The structure is as follows: The rationale for this scenario is to map the port of the host and the port of the Docker container (that is, a port accessing the host will map to the port of the Docker container), the host is then configured with Nginx to acce
