Mesos Cookbook

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 >= 12.14.60

Platform

Tested on

• Ubuntu 16.04
• Ubuntu 15.10
• Ubuntu 14.04
• Ubuntu 12.04
• Debian 8.6 (with Java 7)
• CentOS 7.2
• CentOS 6.8

Supported Mesos versions

This cookbook is tested against the following Apache Mesos versions:

• 1.1.0
• 1.0.1
• 1.0.0

We intend to support at most the three latest versions of Apache Mesos.

Attributes

In order to keep the README managable and in sync with the attributes, this cookbook documents attributes inline. The usage instructions and default values for attributes can be found in the individual attribute files.

Configuring Mesos via attributes

This cookbook introduces a few points of validation to prevent passing Mesos invalid configuration options. The ruby block mesos-slave-configuration-validation and mesos-master-configuration-validation extract a hash of all valid Mesos configuration options from the --help output of the master and slave binary and check it against the provided attributes. This cookbook will fail to converge if you try to use an invalid configuration option as a command line flag attribute under ['mesos']['master']['flags'] or ['mesos']['slave']['flags'] hashes.

The valid list of Mesos options may be found at: https://github.com/apache/mesos/blob/master/docs/configuration.md

Recipes

default

The default mesos recipe will run mesos::install.

install

The install recipe installs the specified version of the mesosphere mesos RPM or Debian package and installs it. It’s also configured 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.

repo

The repo recipe contains logic for setting up Mesosphere debian and RPM repositories.

Dependencies

The following cookbooks are dependencies:

• apt
• yum
• java

The following cookbooks are suggested:

• exhibitor (used for discovering ZooKeeper ensembles via Netflix Exhibitor)

Usage

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

chef_type:           role
default_attributes:
description:
env_run_lists:
json_class:          Chef::Role
name:                mesos_master
override_attributes:
  mesos:
    version: 1.0.1
    master:
      flags:
        cluster: 'mesos-sandbox'
        zk: 'zk://127.0.0.1:2181/mesos'
run_list:
  recipe[mesos::master]

Here is a sample role for creating a Mesos slave node with a seperate ZooKeeper ensemble dynamically discovered via Netflix Exhibitor:

chef_type:           role
default_attributes:
description:
env_run_lists:
json_class:          Chef::Role
name:                mesos_slave
override_attributes:
  mesos:
    version: 1.0.1
    slave:
      flags:
        master: 'zk://127.0.0.1:2181/mesos'
run_list:
  recipe[mesos::slave]
