Quick mesos cluster with marathon/chronos using docker-compose.

compose-mesos

A Docker Compose sandbox environment with Marathon, Chronos, Consul, HAProxy, Registrator, and a Mesos cluster consisting of one master and three slaves.

Thanks to dontrebootme for the base repo and excellent blog post.

Usage

docker-compose up

Then access the various components via the correct port:

• Marathon URL: http://DOCKER_HOST:8080
• Mesos URL: http://DOCKER_HOST:5050
• Chronos URL: http://DOCKER_HOST:4400
• Consul URL: http://DOCKER_HOST:8500

Service Orchestration

Application services can be deployed using the Marathon API:

# Starts up 10 microbot apps in docker containers... See microbot.json file
$ curl -X POST -H "Content-Type: application/json" http://DOCKER_HOST:8080/v2/apps [email protected]

As the containers start, Registrator receives the event, notifies Consul, which updates the HAProxy load balancer configuration (via Consul-Template).

You can then reach a microbot app through the load balancer, via:

http://microbot.docker.local

...as long as you've configured a wildcard DNS *.docker.local to point to the DOCKER_HOST IP (or just add it to your /etc/hosts file):

# Use your DOCKER_HOST IP here
192.168.99.100   microbot.docker.local

Other applications can be started in the same way, automatically load balancing based off of the DNS name {app}.docker.local and the Marathon app ID. See haproxy-consul for more information.
