Use HAProxy with Docker


1. Create Dockerfile for HAProxy Build with Docker

FROM haproxy:1.7 // Set HAProxy version
ADD haproxy.cfg /usr/local/etc/haproxy/haproxy.cfg
cs


2. Docker build using Dockerfile created

cs


3.  After you build Dockerfile, you can find docker images that is my-haproxy

$ docker images
REPOSITORY                              TAG                 IMAGE ID            CREATED             SIZE
my-haproxy                              latest              98f53e224010        5 hours ago         134.9 MB

    • auth - account ID / account PW
  • web
    • Bind 80 port.
    • balance mode is roundrobin.
    • health check for web1, web2.

5. Use haproxy.cfg that you set to run the docker.
