[chef] Re: Windows Reboots

[Aimelyne Mochiron < >]

Hi Simon,

Wouldn't something like this work for your use case?


reboot "my_name" do
  action :nothing
  reason "reason"
  # other params as appropriate
end

powershell_script 'rename_hostname'
  code <<-EOH
    # code
  EOH
  # insert guard here to ensure this doesn't run if correct hostname's already set
  notifies :request_reboot, "reboot[my_name]"
end

powershell_script "join_domain"
  code <<-EOH
  # code
  EOH
  not_if {reboot_pending? || some_other_test} 
  notifies :request_reboot, "reboot[my_name]"
end

On the first run, rename_hostname will run, then set a reboot event that'll trigger at the end of the Chef run (thanks to the :request_reboot action); join_domain will be skipped owing to the reboot_pending? call. 

Second run, rename_hostname should be skipped, join_domain will run and notify for a reboot again. 

Third and subsequent times, nothing should happen.

To make sure chef-client runs on reboot, you could create a task, using e.g. windows_task from the Windows cookbook (https://github.com/opscode-cookbooks/windows), then you could notify the windows_task resource appropriately (adding it during the first run, then deleting it in the third one- make that conditional on e.g. reboot_pending? returning false).

HTH,

am

I’ve tried doing the following also:

 

1.       Changed my run list to run just call the join domain script.

2.       Add an include in the join domain recipe to call the rename_hostname recipe.

3.       When the client is run, the rename_hostname recipe is called and the reboot is run.

4.       The chef run gets terminated, so the domainjoin is never completed, but the machine reboots.

 

Is there any way of pausing the chef-run to wait for the machine to come back up, then run the domain join and reboot after that?

 

Cheers,

Simon.

Hi Daniel,

 

Many thanks, I now get this:

 

10.x.x.x [2015-03-31T09:35:41+01:00] WARN: Rebooting server at a recipe's request. Details: {:delay_mins=>3, :reason=>"Cannot continue Chef run without a reboot.", :timestamp=>2015-03-31 09:35:40 +0100, :requested_by=>"now"}

 

And the box restarts. The only thing is the chef run terminates and doesn’t go onto the next recipe. I was expecting the run to pause for 3 mins and then carry on after the reboot, is that how it should work? Do I need to put recipe depends on statements in the domainjoin recipe?

 

I have this in the rename machine recipe:

 

reboot "now" do

  action :nothing

  reason "Cannot continue Chef run without a reboot."

  delay_mins 3

end

 

powershell_script "rename_hostname" do

code <<-EOH

 

….

EOH

 

notifies :reboot_now, 'reboot[now]', :immediately

 

END

 

Cheers,

Simon.

In addition,

There's the reboot_pending? helper: https://docs.chef.io/dsl_recipe.html#reboot-pending

That allows you to guard against the reboot pre-emptively.
