Launching Containers Using Docker on Mesos and Marathon

Mesos and Marathon Setup

refer blog: 

Mesos and Marathon setup

Installing Docker

use the below command to install docker 

curl -sSL https://get.docker.com/ | sh

Configuring mesos to allow Docker

echo 'docker,mesos' | sudo tee /etc/mesos-slave/containerizers

echo '5mins' > /etc/mesos-slave/executor_registration_timeout

Launching Docker Containers using Marathon Framework

sample marathon application definition (JSON) to run redis

redis.json

{   "container": {     "type": "DOCKER",     "docker": {       "image": "redis"     }   },   "id": "redis",   "instances": 1,   "cpus": 0.25,   "mem": 256,   "uris": [] }

Use the below REST API call to deploy redis container

curl -i -H 'Content-Type: application/json' -d@redis.json marathon_host:8080/v2/apps

Now you can check the deployed app / container in different ways

• Using marathon Web UI
• Using mesos Web UI
• Marathon REST API

         curl http://0.0.0.0:8080/v2/apps | python -m json.tool

•  Using Docker commands
  

          $sudo docker ps
