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 supermarket mailing list.

Habitat Cookbook

Build Status Cookbook Version

This cookbook provides resources for working with Habitat. It is intended that these resources will be included in core Chef at some point in the future, so it is important to note:

  • APIs are subject to change
  • Code style adheres to chef-core (chefstyle)
  • Habitat is a rapidly changing product, and this cookbook may change rapidly as well

(this is a pre-1.0 version, after all)

Requirements

Platforms

  • RHEL 6+
  • Ubuntu 12.04+

Chef

Chef 12.11, for the systemd_unit resource.

Resources are written in the style of Chef 12.5 custom resources where applicable or available.

Cookbooks

This cookbook has no external cookbook dependencies. It does not attempt to maintain backwards compatibility with previous Chef versions.

Resources

hab_install

Installs Habitat on the system using the install script.

This resource is written as a Chef 12.5 custom resource.

Actions

  • install: Installs Habitat. Does nothing if the hab binary is found in the default location for the system (/bin/hab on Linux, /usr/local/bin/hab on macOS)
  • upgrade: Installs the latest version of Habitat, does not check if the binary exists

Properties

  • install_url: URL to the install script, default is from the habitat repo
  • version: The version of habitat to install (defaults to latest)
  • channel: The release channel to install from (defaults to stable)

Examples

hab_install 'install habitat'
hab_install 'install habitat' do
  version "0.12.0"
end

hab_package

Install the specified Habitat package. Requires that Habitat is installed

This resource is written as a library resource because it subclasses Chef's package resource/provider to get features such as the multi-package API).

Actions

  • install: Installs the specified package
  • upgrade: aliased to install

Properties

  • package_name: A Habitat package name, must include the origin and package name separated by /, for example, core/redis
  • version: A Habitat version which contains the version and optionally a release separated by /, for example, 3.2.3 or 3.2.3/20160920131015
  • depot_url: The habitat depot url where packages will be downloaded from (defaults to public habitat depot)

While it is valid to pass the version and release with a Habitat package as a "fully qualified package identifier" when using the hab CLI, they must be specified using the version property when using this resource. See the examples below.

Examples

hab_package "core/redis"

hab_package "core/redis" do
  version "3.2.3"
end

hab_package "core/redis" do
  version "3.2.3/20160920131015"
end

hab_service

Manages a Habitat application service using systemd. It will drop off a unit file using the systemd_unit provider in Chef.

This resource is written as a library resource because it subclasses Chef's service resource/provider to get built in properties and actions.

This resource requires Chef 12.11 or higher.

A future version of this resource may support other service providers.

Actions

  • start: (default action) writes a systemd_unit for the application and starts the service
  • enable: writes the systemd_unit for the application
  • stop: stops the application service

Properties

  • unit_content: Content passed into the systemd_unit resource as its content property. By default this is a hash that starts the service with /bin/hab start.
  • environment: An environment string to pass into the unit file. By default this contains the location of the SSL certificate from the Habitat core/cacerts package.

Examples

hab_package 'core/redis'

hab_service 'core/redis' do
  action :enable
end

# unit_content as a hash
hab_service 'myorigin/myapp' do
  unit_content({
    Unit: {
      Description: 'myapp',
      After: 'network.target audit.service'
    },
    Service: {
      Environment: 'HAB_MYAPP=workers=3'
      ExecStart: '/bin/hab start myorigin/myapp'
    }
  })
end

# unit_content as a string
hab_service 'myorigin/myapp' do
  unit_content <<-EOF
[Unit]
Description = myapp
After = network.target audit.service

[Service]
Environment = "HAB_MAPP=workers=3"
ExecStart = "/bin/hab start myorigin/myapp"
Restart = "on-failure"
EOF
end
