Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Update your omnibus! This cookbook can install the omnibus Chef package into your system if you are currently running via gem install, and it can keep your omnibus install up to date.


Add the recipe to your run list and specify what version should be installed on the node:

knife node run_list add recipe[omnibus_updater]

In your role you'll likely want to set the version. It defaults to nothing, and will install the latest..

  :omnibus_updater => {
    :version => '11.4.0'

It can also uninstall Chef from the system Ruby installation if you tell it to:

  :omnibus_updater => {
    :remove_chef_system_gem => true


Latest Version

Force installation of the latest version regardless of value stored in version attribute by setting the force_latest attribute.

Chef Killing

By default the omnibus updater will kill the chef instance by raising an exception. You can turn this off using the kill_chef_on_upgrade attribute. It is not recommended to turn this off. Internal chef libraries may change, move, or no longer exist. The currently running instance can encounter unexpected states because of this. To prevent this, the updater will attempt to kill the Chef instance so that it can be restarted in a normal state.

Restart chef-client Service

Use the restart_chef_service attribute to restart chef-client if you have it running as a service.


Prereleases can be installed via the auto-installation using prerelease attribute.


If you want to disable the updater you can set the disabled attribute to true. This might be useful if the cookbook is added to a role but should then be skipped for example on a Chef server.

Prevent Downgrade

If you want to prevent the updater from downgrading chef on a node, you can set the prevent_downgrade attribute to true. This can be useful for testing new versions manually. Note that the always_download attribute takes precedence if set.
