HAProxy Config

The configuration file is stored on the VM under /opt/ha-proxy-certbot/config/haproxy.cfg

  1. Become root to modify it.
  2. Open the file, modify and save it. 
  3. Check the container ID
    docker ps
  4. Restart container for the changes to take effect
    docker restart <CONTAINER_id>

There are four essential sections to an HAProxy configuration file. They are global, defaults, frontend, and backend. These four sections define how the server as a whole performs, what your default settings are, and how client requests are received and routed to your backend servers.
