mod_cluster dev image offering Apache HTTP Server and mod_cluster load balancer built from sources

mod_cluster-dockerhub (jota modification)

Based on mod_cluster-dockerhub by Karm

This is my modification of the original repo with my Dockerfile and mod_cluster.conf files.

Why I created this fork? I intended to:

• Have my own customized Docker image
• Add an application VirtualHost in mod_cluster.conf configuration, so I can begin using this image with real apps deployed in backend application servers.

Configuration

You can configure the mod_cluster parameters through following environment variables provided to docker run command:

• MODCLUSTER_PORT listening port (default: 6666)
• MODCLUSTER_ADVERTISE On/Off flag for ServerAdvertise (default: On)
• MODCLUSTER_ADVERTISE_GROUP Advertise address and port (default: 224.0.1.105:23364)
• MODCLUSTER_NET a Require ip value for the listener (default: 172.)
• MODCLUSTER_MANAGER_NET a Require ip value for the mod_cluster manager on path /mcm (default: value of MODCLUSTER_NET variable)

The defaults could work in your Docker environment.

Example usage

Build the custom image

docker build -q --rm --tag=mod_cluster_jota .

Run the container

You can modify the variables as you need, this is just an example:

docker run -it --rm --net host --name mod_cluster-app1 \
-e MODCLUSTER_PORT=6666 \
-e MODCLUSTER_ADVERTISE=On \
-e MODCLUSTER_NET=192.168.1 \
-e MODCLUSTER_MANAGER_NET=192.168.1 \
mod_cluster_jota

Check if it is working:

curl 127.0.0.1:6666/mcm

To inspect the container use:

docker exec -i -t mod_cluster-app1 bash
