Install via URL¶
The Chef 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 Chef install script can be run on UNIX, Linux, and Microsoft Windows platforms.
UNIX and Linux¶
On UNIX and Linux systems the Chef 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 Chef 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 Chef install script supports the following options:
-c
(-channel
on Microsoft Windows)- The release channel from which a package is pulled. Possible values:
current
orstable
. 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.
