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.

Description

Because every Chef needs a little Salt.

Improved Remote Execution for Open Source Chef

Install Salt master and/or minion.

Why would anyone ever want to use both Salt and Chef?

I'm glad you asked!

Open Source Chef is weak in one key area that Salt just so happens to be very strong: remote execution. knife ssh "name:*" "sudo chef-client" really doesn't scale very well.

Think of Salt as the Push Jobs plugin for Open Source Chef. They're even based on the same basic messaging technology: ZeroMQ.

And as of SaltStack 2014.7, they have significantly improved Chef integration. Want to do a chef client run on all your nodes: salt "*" chef.client Then, you can use the job management commands to check on the status of your run.

And since you made or are hopefully about to make the wise decision to use this cookbook, you'll get even better Chef-Salt integration. The cookbook will automatically sync up the metadata (grains in Salt parlance) between Chef and Salt to allow you to filter on role or environment or custom markers.

Requirements

Platforms

This cooked has been confirmed to work on:

  • Ubuntu 10.04 or later
  • CentOS 5+, RedHat 5+, Scientific Linux 5+
  • Fedora 19, 20
  • Debian 7 (Wheezy)

Dependencies

  • apt
  • yum
  • yum-epel

Attributes

  • node['salt']['version'] - Package version to be installed (defaults to nil for latest). This attribute applies to both the master and minion, since you'll want to keep their versions synced up
  • node['salt']['role']['master'] - Salt master role (defaults to salt_master)
  • node['salt']['role']['minion'] - Salt minion role (defaults to salt_minion)

Minion

  • node['salt']['minion']['master'] - Address or list of masters, if not using built-in search functionality.
  • node['salt']['minion']['master_environment'] - The environment in which to search for a master; or nil to search all environments (defaults to the node's environment)
  • node['salt']['minion']['grains'] - Map of custom grains for tagging the minion. Each entry may contain a single string value or a list of strings.
  • node['salt']['minion']['config_cookbook'] and node['salt']['minion']['config_template'] allow you to override the template used to generate the minion config file /etc/salt/minion

Master

  • node['salt']['master']['config_cookbook'] and node['salt']['master']['config_template'] allow you to override the template used to generate the master config file /etc/salt/master

See attribute files for more supported attributes.

Recipes

default

Nothing; reserved to include future LWRPs.

master

Install Salt master using OS package manager.

minion

Install Salt master using OS package manager.

Resources/Providers

None at this time.

Usage

Define two roles named salt_master and salt_minion, which include the corresponding recipes. The nodes will automatically discover each other within the same environment (when using Chef Server).

If you want your Salt Masters to operate across all environments, set node['salt']['minion']['master_environment'] to nil for all minions.

At the moment, you will need to approve access for any minions with the salt-key -A command. A future version of this cookbook will handle this automatically.

Using Salt

Targetting Minions

This cookbook attempts to keep metadata synchronized between Chef and Salt.

Minions are automatically tagged (and updated on every chef-client run) with the following two standard Salt grains:

  • environment contains the chef environment of the node: salt -G "environment:production" ...
  • role contains a complete expanded list of roles assigned to the node (this includes roles within roles): salt -G "role:salt_minion" ...

In addition, you can define your own custom grains using the node['salt']['minion']['grains'] attribute. See above.
