Chef Software install script

You can use the Chef Software install script to install any Chef software—including Chef Infra Client, Chef Infra Server, and Chef InSpec—on UNIX, Linux, and Windows platforms.

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.

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.

The Commercial Download API supports the current or stable channels. The Community Download API only supports the stable channel.

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 chef,chef-backend,chef-server,inspec,chef-workstation,manage and supermarket. 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 semver.org.

Release channels

Chef releases packages from the following release channels:

ChannelDescription
stableA build from this channel is an “official” release that has passed full user acceptance testing. Artifacts in this channel are retained indefinitely.
currentA build from this channel is an “integration” build that has passed full testing, but has not been officially released. Artifacts in this channel are retained for 30 days and then removed automatically.

Use the stable channel when installing Chef products on production systems.
