Install via URL

[edit on GitHub]

The Omnitruck install script does the following:

  • Detects the platform, version, and architecture of the machine on which the installer is to be 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 Install Script

The Omnitruck install script can be run on UNIX, Linux, and Microsoft Windows platforms.

UNIX and Linux

On UNIX and Linux systems the Omnitruck install script is invoked 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 the Omnitruck install script is invoked using Windows PowerShell:

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

Install Script Options

In addition to the default install behavior, the Omnitruck 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. A list of valid product names can be found at https://omnitruck.chef.io/products. Default value: chef.
-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 http://semver.org/.
