Get the leader of a marathon cluster

arathon-cli --host host-01:8080 leader


Code": 200,
leader": "host-02:8080"

Force the leader step down

rathon-cli --host host-01:8080 rmleader


Code": 200,
message": "Leadership abdicted"

After a leader steps down, Marathon will perform an election to determine the next leader. You can confirm that the leadership changed:

rathon-cli --host host-01:8080 leader

Code": 200,
leader": "host-01:8080"

Managing Applications

Applications are identified by their “id” field.

List all apps running on the cluster

To shorten the command line, we can set the MARATHON_HOST environment variable:

rt MARATHON_HOST=host:8080

rathon-cli lsapp

Code": 200,
apps": [
  {
     "id": "/hello-rails",
     "cmd": "cd hello \u0026\u0026 bundle install \u0026\u0026 bundle exec unicorn -p $PORT",
     "cpus": 1,
     "env": {
        "RAILS_ENV": "production"
     },
     "instances": 1,
     "mem": 100,
     "ports": [
        10001
     ],

 .. <output omitted>

List a single app running on the cluster

rathon-cli lsapp hello-rails

Code": 200,
app": {
  "id": "/hello-rails",
  "cmd": "cd hello \u0026\u0026 bundle install \u0026\u0026 bundle exec unicorn -p $PORT",
  "cpus": 1,
  "env": {
     "RAILS_ENV": "production"
  },
  "instances": 1,
  "mem": 100,
  "ports": [

  ... <output omitted>

Delete an application

This will terminate and delete an application

rathon-cli rmapp hello-rails
[0000] Application deleted: hello-rails

Launch an application form a json description file.

Use a standard Marathon application configuration file to launch an application. The examples/ directory contains sample files.

rathon-cli app --file examples/rails.json
[0000] Application deployed app: hello-rails

Code": 201,
version": "2015-02-16T14:27:55.572Z"

Refer to the Marathon Documentation for more configuration examples.
