Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Description

Application cookbook for installing the Apache Mesos cluster manager. Mesos provides efficient resource isolation and sharing across distributed applications, or frameworks. This cookbook installs Mesos via packages provided by Mesosphere.

Requirements

Chef 11.4.0+

This cookbook assumes you will be running a ZooKeeper ensemble for production use of Mesos.

The following cookbooks are dependencies:

  • apt
  • java
  • zookeeper (used for discovering ZooKeeper ensembles via Netflix Exhibitor)
  • docker

Platform:

Tested on

  • Ubuntu 12.04
  • Ubuntu 13.04

I intend to release updates to this cookbook to support rhel and centos 6.

This cookbook includes cross-platform testing support via test-kitchen, see TESTING.md.

Attributes

  • node['mesos']['version'] - Mesosphere Mesos package version. Default: '0.14.0-rc4'.
  • node['mesos']['cluster_name'] - Human readable name for the cluster, displayed in the webui. Default: 'MyMesosCluster'.
  • node['mesos']['port'] - Port to listen on. Default: 5050.

  • node['mesos']['isolation_type'] - Isolation mechanism, may be one of: process, cgroups. Default: 'process'.
  • node['mesos']['zookeeper_server_list'] - List of ZooKeeper hostnames or IP addresses. Default: [].
  • node['mesos']['zookeeper_port'] - ZooKeeper port. Default: 2181.
  • node['mesos']['zookeeper_path'] - ZooKeeper path. Default: 'mesos'.
  • node['mesos']['zookeeper_exhibitor_discovery'] - Flag to enable ZooKeeper ensemble discovery via Netflix Exhibitor. Default: false.
  • node['mesos']['zookeeper_exhibitor_url'] - Netflix Exhibitor ZooKeeper ensemble url.
  • node['mesos']['python_egg'] - URL of mesos python egg to download

Recipes

default

The default mesos recipe will run mesos::install.

install

The install recipe pulls down the specified version of the mesosphere mesos package and installs it. It also configures to stop both mesos-master and mesos-slave init files so that they don't automatically start on server restart.

master

The master recipe runs mesos::install as well as creating several mesos-master configuration files that are used at startup. This recipe also uses the zookeeper attributes and/or exhibitor attributes to configure the mesos-master using zookeeper. Lastly it sets the mesos-master init config to 'start' so that mesos-master is started on server restart.

slave

The slave recipe runs mesos::install as well as creating several mesos-slave configuration files that are used at startup. This recipe also uses the zookeeper attributes and/or exhibitor attributes to configure the mesos-slave using zookeeper. Lastly it sets the mesos-slave init config to 'start' so that mesos-slave is started on server restart.

docker

The docker recipe installs docker via Brian Flad's docker cookbook as well as Jason Dusek's mesos-docker script as a mesos executor. After running this recipe on a mesos slave you should be able to run the mesos-docker examples listed in Jason Dusek's docker on mesos blog post.

Usage

Here is a sample role for configuring a Mesos master in a ZooKeeper backed production mode.

Here is a sample role for creating a Mesos slave node with a seperate ZooKeeper ensemble dynamically discovered via Netflix Exhibitor: YAML chef_type: role default_attributes: description: env_run_lists: json_class: Chef::Role name: mesos_slave override_attributes: mesos: version: 0.15.0 cluster_name: mesos-sandbox zookeeper_path: 'mesos' zookeeper_exhibitor_discovery: true zookeeper_exhibitor_url: 'http://zk-exhibitor-endpoint.example.com:8080' run_list: recipe[mesos::slave]

Here is a sample role for creating a Mesos slave node running the experimental docker executor. This node is also dynamically configured via zookeeper and exhibitor. (Note: this recipe only works with Ubuntu 13.04 as of now.)
