Chef Software Install Script

[edit on GitHub]

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 Windows platforms. The terms ‘omnibus’ and ‘omnitruck’ are only relevant to the build processes used internally at Chef Software.

UNIX, Linux, and macOS

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.

Windows

On 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 Windows)

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

-d (-download_directory on 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 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 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 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 Windows)

Install package downloaded from a direct URL.

-a (-checksum on Windows)

The SHA256 for download_url_override

-v (-version on 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/.
