Chef Software Inc Packages

[edit on GitHub]

Packages for Chef Software Inc. products may be installed using platform-native package repositories or the Chef Software Install script. Both installation methods support the following release channels:

Chef recommends using the stable channel when installing any of these products on production systems.

Package Repositories

The stable and current release channels support the following package repositories:

• Apt (Debian and Ubuntu platforms)
• Yum (Enterprise Linux platforms)

Chef Software Inc. GPG public key is can be downloaded here.

Debian / Ubuntu

To set up an Apt package repository for Debian and Ubuntu platforms:

1. Enable Apt to fetch packages over HTTPS:

   sudo apt-get install apt-transport-https
   

2. Install the public key for Chef Software Inc:

   wget -qO - https://packages.chef.io/chef.asc | sudo apt-key add -
   

3. Create the Apt repository source file:

   echo "deb https://packages.chef.io/repos/apt/<CHANNEL> <DISTRIBUTION> main" > chef-<CHANNEL>.list
   

   Replace <CHANNEL> with the release channel: stable or current.

   Replace <DISTRIBUTION> with the appropriate distribution name:

   • For Debian 8: jessie
   • For Debian 9: stretch
   • For Debian 10: buster
   • For Ubuntu 16.04: xenial
   • For Ubuntu 18.04: bionic
   • For Ubuntu 20.04: focal

4. Update the package repository list:

   sudo mv chef-stable.list /etc/apt/sources.list.d/
   

5. Update the cache for the package repository:

   sudo apt-get update
   

Enterprise Linux

To set up a Yum package repository for Enterprise Linux platforms:

1. Install the public key for Chef Software Inc:

   sudo rpm --import https://packages.chef.io/chef.asc
   

2. Create the Yum repository source file:

   cat >chef-<CHANNEL>.repo <<EOL
   [chef-<CHANNEL>]
   name=chef-<CHANNEL>
   baseurl=https://packages.chef.io/repos/yum/<CHANNEL>/el/<VERSION>/\$basearch/
   gpgcheck=1
   enabled=1
   EOL
   

   Replace <CHANNEL> with the release channel: stable or current.

   Replace <VERSION> with your Enterprise Linux version; the allowable versions are 6, 7, or 8.

3. Update the package repository list:

   sudo yum-config-manager --add-repo chef-stable.repo
   

   Note that the yum-config-manager command requires the yum-utils package, which is not installed on CentOS by default. You can install the package by running sudo yum install yum-utils, or you can use the mv command to add the repository to the /etc/yum.repos.d/ directory:

   sudo mv chef-stable.repo /etc/yum.repos.d/
   

Chef Software Install Script

The Chef Software install script can be used to install any Chef Software, including things like Chef Infra Client, Chef Infra Server, Chef Inspec. This script does the following:

• Detects the platform, version, and architecture of the machine on which the installer is being executed
• Fetches the appropriate package, for the requested product and version
• Validates the package content by comparing SHA-256 checksums
• Installs the package

Run the Chef Software Install Script

The Chef Software Install script can be run on UNIX, Linux, and Microsoft Windows platforms. The terms ‘omnibus’ and ‘omnitruck’ are only relevant to the build processes used internally at Chef Software.

UNIX and Linux

On UNIX, Linux, and macOS systems, invoke the Chef Software Install script with:

curl -L https://omnitruck.chef.io/install.sh | sudo bash

and then enter the local password when prompted.

Microsoft Windows

On Microsoft Windows systems, invoke the Chef Software Install script using Windows PowerShell:

. { iwr -useb https://omnitruck.chef.io/install.ps1 } | iex; install

Chef Software Install Script Options

In addition to the default install behavior, the Chef Software Install script supports the following options:

-c (-channel on Microsoft Windows)

The release channel from which a package is pulled. Possible values: current or stable. Default value: stable.

-d (-download_directory on Microsoft Windows)

The directory into which a package is downloaded. When a package already exists in this directory and the checksum matches, the package is not re-downloaded. When -d and -f are not specified, a package is downloaded to a temporary directory.

-f (-filename on Microsoft Windows)

The name of the file and the path at which that file is located. When a filename already exists at this path and the checksum matches, the package is not re-downloaded. When -d and -f are not specified, a package is downloaded to a temporary directory.

-P (-project on Microsoft Windows)

The product name to install. Supported versions of Chef products are automate, chef, chef-server, inspec, chef-workstation, chefdk, supermarket, chef-backend, push-jobs-client, and push-jobs-server. Default value: chef.

-s (-install_strategy on Microsoft Windows)

The method of package installations. The default strategy is to always install when the install.sh script runs. Set to “once” to skip installation if the product is already installed on the node.

-l (-download_url_override on Microsoft Windows)

Install package downloaded from a direct URL.

-a (-checksum on Microsoft Windows)

The SHA256 for download_url_override

-v (-version on Microsoft Windows)

The version of the package to be installed. A version always takes the form x.y.z, where x, y, and z are decimal numbers that are used to represent major (x), minor (y), and patch (z) versions. A two-part version (x.y) is also allowed. For more information about application versioning, see https://semver.org/.
