internavenue/centos-haproxy repository overview

⁠docker-centos-haproxy

A Dockerfile that produces a Vagrant-ready, CentOS 7-based Docker image that will run the latest stable HAProxy⁠.

The build is based on [internavenue/docker-centos-base][docker-centos-base].

⁠Included packages (and their dependencies)

• HAProxy

⁠Image Creation

This example creates the image with the tag internavenue/centos-haproxy, but you can change this to use your own username.

$ docker build -t="internavenue/centos-haproxy" .

Alternately, you can run the following if you have GNU Make installed...

$ make

You can also specify a custom docker username like so:

$ make DOCKER_USER=internavenue

⁠Container Creation / Running

The HAProxy load balancer can be configured to use external volumes, such as

• /var/log - for logging
• /run - to access the haproxy.pid; useful if you want to send signals from the host
• /vagrant - if you want to the image with Vagrant
• /var/lib/haproxy - to examine runtime offline data that HAProxy produce.

This example uses /srv/docker/lon-dev-haproxy to host the web application, but you can modify this to your needs.

$ mkdir -p /srv/docker/lon-dev-haproxy
$ docker run -d -name="lon-dev-haproxy" \
             -p 127.0.0.1:80:80 \
             -v /srv/docker/lon-dev-haproxy/log:/var/log \
             -v /srv/docker/lon-dev-haproxy/run:/run \
             -v /srv/docker/lon-dev-haproxy/lib:/var/lib/haproxy \
             internavenue/centos-haproxy

Alternately, you can run the following if you have GNU Make installed...

$ make run

You can also specify a custom port to bind to on the host, a custom web root directory, and the superuser username and password on the host like so:

$ sudo mkdir -p /srv/docker/lon-dev-haproxy
$ make run PORT=127.0.0.1:8080 \
           DATA_DIR=/my/spec/data/dir \
