C * Previously, Chef required the LCM Refreshmode to be set to Disabled when utilizing dsc_resource. Microsoft has relaxed this requirement in Windows Management Framework 5 (WMF5) (PowerShell 5.0.10586.0 or later). Now, we only require the RefreshMode to be disabled when running on earlier versions of PowerShell 5. * Added a reboot_action attribute to dsc_resource. If the DSC resource indicates that it requires a reboot, reboot_action can use the reboot resource to either reboot immediately (:reboot_now) or queue a reboot (:request_reboot). The default value of reboot_action is :nothing. +In addition to `:immediately` and `:delayed`, we have added the new notification timing `:before`. `:before` will trigger just before the +resource converges, but will only trigger if the resource is going to +actually cause an update. + +For example, this will stop apache if you are about to upgrade your particularly sensitive web app (which can't run while installing for +whatever reason) and start it back up afterwards. + +``` +execute 'install my app' do + only_if { i_should_install_my_app } +end + +# Only stop and start apache if i_should_install_my_app +service 'httpd' do + action :nothing + subscribes :stop, 'template[/etc/httpd.conf]', :before + subscribes :start, 'template[/etc/httpd.conf]' +end +``` + ## Other items There are a large number of other PRs in this release. Please see the CHANGELOG for the full set of changes. |
