Introduction

Description of the mini-cluster

A typical production installation of a Mesos cluster is shown in the following diagram:

For this tutorial we will be using an all-in-one installation of Mesos/Marathon/Chronos.

This is the docker compose file used to setup the mini-cluster:

version: '3.7'

services:
  zookeeper:
    image: indigodatacloud/zookeeper
    expose:

    environment:
      - PORTS=9090
    depends_on:
      - marathon

Start the cluster:

cd /opt/mesos
docker-compose up -d

Check that the services are up and running:

docker-compose ps

       Name                      Command               State                    Ports

Use your browser to connect to Mesos on port 5050 of your machine:

Tip

Use the following command to get the ip of your VM:

ip a show ens3

Open a new tab of your browser and connect to Marathon on port 8080 of your machine:

Finally in another tab connect to Chronos on port 4400 of your machine:
