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

Description

Manage deployment and configuration of underlying Mesosphere DCOS installation.

Requirements

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

Usage

The behavior of this cookbook is managed by attributes documented in the attributes file. The node['dcos']['dcos_role'] attribute controls the DCOS role to apply to the node (default is master). The node['dcos']['master_list'] must be set to specify the list of DCOS master node IPv4 addresses to connect at startup (this must be an odd number of masters).

If you would like to have the stable channel, please flip the node['dcos']['dcos_earlyaccess'] to false.

Roles

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 probably be set as override attributes in an Environment to ensure all nodes receive those global settings.

Example Role dcos_master.rb

name "dcos_master"
description "DCOS master role"
run_list "recipe[dcos]"
default_attributes "dcos" => {
    "dcos_role" => "master"
    "master_list" => [ "10.0.2.10" ]
}

Example Role dcos_slave.rb

name "dcos_slave"
description "DCOS slave role"
run_list "recipe[dcos]"
default_attributes "dcos" => {
    "dcos_role" => "slave"
    "master_list" => [ "10.0.2.10" ]
}

Recipe

default

Installs the prerequisites for the Mesosphere DCOS installation, including packages, groups and Docker with OverlayFS enabled. It then downloads and runs the installation package with the settings configured by the node's attributes.

Testing

ChefSpec

There is basic coverage for the default recipe.

InSpec

TBD

Test Kitchen

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