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.

Build Status


Manage deployment and configuration of underlying Mesosphere DC/OS installation.


Only Red Hat or CentOS 7.x are currently supported.


The behavior of this cookbook is managed by attributes documented in the [attributes file](attributes/default.rb). The node['dcos']['dcos_role'] attribute controls the DC/OS role to apply to the node (default is master). The node['dcos']['config']['master_list'] must be set when node['dcos']['config']['master_discovery'] is set to static to specify the list of DC/OS master node IPv4 addresses to connect at startup (this must be an odd number of masters and cannot be changed, later).

This cookbook uses the EarlyAccess channel, by default. Setting node['dcos']['dcos_version'] to stable will install the latest stable version of DC/OS (currently 1.9.3).


You can create a Chef Role and apply it to nodes as necessary to specify master, slave and slave_public, as appropriate. Any additional configuration should be set as override attributes in an Environment to ensure that all nodes receive those global settings.

Example Role dcos_master.rb

name "dcos_master"
description "DC/OS master role"
run_list "recipe[dcos]"
default_attributes "dcos" => {
    "dcos_role" => "master",
    "config" => {
        "master_list" => [ "" ]

Example Role dcos_slave.rb

name "dcos_slave"
description "DC/OS slave role"
run_list "recipe[dcos]"
default_attributes "dcos" => {
    "dcos_role" => "slave",
    "config" => {
        "master_list" => [ "" ]



Installs the prerequisites for the Mesosphere DC/OS installation, including packages, and groups. Docker with OverlayFS is installed and enabled if node['dcos']['manage_docker'] is set to true, which is the default. Next, the recipe downloads and runs the installation package with the settings configured by the attributes under node['dcos']['config'].



There is basic coverage for the default recipe.



Test Kitchen

The included [.kitchen.yml](.kitchen.yml) runs the default master deployment in a generic fashion. The included [.kitchen.local.yml.example](.kitchen.local.yml.example) shows alternate settings for running multi-master with slaves on GCE (you will have to rename and update accordingly).
