This is a Puppet module for managing Mesos nodes in a cluster.

• Puppet 3 (or 2.6 with hiera gem)
• Mesos binary package
  • Debian/Ubuntu
    • mesos deb packaging
    • mesosphere packages
  • RedHat/CentOS
    • mesosphere packages

Should be as simple as this, on master node:

class{'mesos::master': }

For slave you have to specify either master or zookeeper node(s) to connect.

class{'mesos::slave':
  master => '192.168.1.1'
}

• enable - install Mesos slave service (default: true)
• master- ip address of Mesos master (default: localhost)
• master_port - Mesos master's port (default: 5050)
• zookeeper - Zookeeper URL string (which keeps track of current Mesos master)
• work_dir - directory for storing task's temporary files (default: /tmp/mesos)
• env_var - slave's execution environment variables - a Hash, if you are using Java, you might need e.g.:

class{'mesos::slave':
  master  => '192.168.1.1',
  env_var => {
    'JAVA_HOME' => '/usr/bin/java'
  }
}

in a similar manner you can specify cgroups isolation:

class{'mesos::slave':
  zookeeper  => 'zk:https://192.168.1.1:2181/mesos',
  isolation  => 'cgroups',
  cgroups    => {
    'hierarchy' => '/sys/fs/cgroup',
    'root'      => 'mesos',
  }
}

All configuration could be handled by hiera.

Either specify one master

mesos::master      : '192.168.1.1'

or Zookeeper could be use for a fault-tolerant setup (multiple instances of zookeeper are separated by comma):

mesos::zookeeper   : 'zk:https://192.168.1.1:2181/mesos'

Some parameters are shared between master and slave nodes:

mesos::master_port : 5050
mesos::log_dir     : '/var/log/mesos'
mesos::conf_dir    : '/etc/mesos'
mesos::owner       : 'mesos'
mesos::group       : 'mesos'

Other are master specific:

mesos::master::cluster     : 'my_mesos_cluster'
mesos::master::whitelist   : '*'

or slave specific:

mesos:slave::env_var:
  JAVA_HOME: '/usr/bin/java'

cgroups with hiera:

mesos::slave::isolation: 'cgroups'
mesos::slave::cgroups:
  hierarchy: '/sys/fs/cgroup'
