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.

Mesos Cookbook Build Status

Install Mesos (http://mesos.apache.org/) and configure mesos master and slave. This cookbook installs Mesos using Mesosphere packages.

All credit to @everpeace for the basis for this cookbook, everpeace/cookbook-mesos.

Platform

Currently only supports ubuntu and centos. But centos support is experimental.

If you would use cgroups isolator or docker containerizer, Ubuntu 14.04 is highly recommended. Note that docker containerizer is only supported by Mesos 0.20.0+.

Recipes

et_mesos::default

Install Java and Mesos, with platform-dependent switches in place.

et_mesos::package

Install Mesos using Mesosphere's mesos package.

One should use the zookeeper cookbook to provision a well-configured ZooKeeper instance or cluster of instances. There is a caveat to this: the mesos package on Ubuntu installs the zookeeper package, so co-locating Mesos and ZooKeeper using that cookbook is tricky, at best. A separate ZK cluster is encouraged.

et_mesos::master

Configure master and cluster deployment configuration files, and start mesos-master.

  • node['et_mesos']['deploy_dir']/masters
  • node['et_mesos']['deploy_dir']/slaves
  • node['et_mesos']['deploy_dir']/mesos-deploy-env.sh
  • node['et_mesos']['deploy_dir']/mesos-master-env.sh

Furthermore, this recipe will also configure upstart configuration files.

  • /etc/mesos/zk
  • /etc/defaults/mesos
  • /etc/defaults/mesos-master

How to configure mesos-master

You can configure mesos-master command line options using the node['et_mesos']['master'] attribute.

If you have a configuration as shown below:

node['et_mesos']['master'] = {
  port:    "5050",
  log_dir: "/var/log/mesos",
  zk:      "zk://localhost:2181/mesos",
  cluster: "MyCluster",
  quorum:  "1"
}

Then mesos-master will be invoked with command line options like this:

mesos-master --zk=zk://localhost:2181/mesos --port=5050 --log_dir=/var/log/mesos --cluster=MyCluster

See the latest Mesos config docs for available options or the output of mesos-master --help.

et_mesos::slave

Configure slave configuration files, and start mesos-slave.

  • node['et_mesos']['deploy_dir']/mesos-slave-env.sh

Furthermore, this recipe also configures upstart configuration files.

  • /etc/mesos/zk
  • /etc/defaults/mesos
  • /etc/defaults/mesos-slave

How to configure mesos-slave

You can configure mesos-slave command line options by node['et_mesos']['slave'] hash. If you have a configuration as shown below:

node['et_mesos']['slave'] = {
  master:         'zk://localhost:2181/mesos',
  log_dir:        '/var/log/mesos',
  containerizers: 'docker,mesos',
  isolation:      'cgroups/cpu,cgroups/mem',
  work_dir:       '/var/run/work'
}

Then mesos-slave will be invoked with command line options like this:

mesos-slave --master=zk://localhost:2181/mesos --log_dir=/var/log/mesos --containerizers=docker,mesos --isolation=cgroups/cpu,cgroups/mem --work_dir=/var/run/work

See the latest Mesos config docs for available options or the output of mesos-slave --help.

Usage

Wrap this cookbook and include_recipe 'et_mesos::master' or include_recipe 'et_mesos::slave', depending on what part of the cluster you need to provision.

The recommendation would be to have two wrapper cookbooks, one for the master(s), and another for your slave(s).
