win_reboot – Reboot a windows machine

Synopsis

• Reboot a Windows machine, wait for it to go down, come back up, and respond to commands.

• For non-Windows targets, use the reboot module instead.

Parameters

Parameter	Choices/Defaults	Comments
connect_timeout integer	Default: 5	Maximum seconds to wait for a single successful TCP connection to the WinRM endpoint before trying again. aliases: connect_timeout_sec
msg string	Default: "Reboot initiated by Ansible"	Message to display to users.
post_reboot_delay integer added in 2.4	Default: 0	Seconds to wait after the reboot command was successful before attempting to validate the system rebooted successfully. This is useful if you want wait for something to settle despite your connection already working. aliases: post_reboot_delay_sec
pre_reboot_delay integer	Default: 2	Seconds to wait before reboot. Passed as a parameter to the reboot command. aliases: pre_reboot_delay_sec
reboot_timeout integer	Default: 600	Maximum seconds to wait for machine to re-appear on the network and respond to a test command. This timeout is evaluated separately for both reboot verification and test command success so maximum clock time is actually twice this value. aliases: reboot_timeout_sec
shutdown_timeout integer	Default: 600	Maximum seconds to wait for shutdown to occur. Increase this timeout for very slow hardware, large update applications, etc. This option has been removed since Ansible 2.5 as the win_reboot behavior has changed. aliases: shutdown_timeout_sec
test_command string	Default: "whoami"	Command to expect success for to determine the machine is ready for management.

Notes

Note

• If a shutdown was already scheduled on the system, win_reboot will abort the scheduled shutdown and enforce its own shutdown.

• Beware that when win_reboot returns, the Windows system may not have settled yet and some base services could be in limbo. This can result in unexpected behavior. Check the examples for ways to mitigate this.

• The connection user must have the SeRemoteShutdownPrivilege privilege enabled, see https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/force-shutdown-from-a-remote-system for more information.

Examples

- name: Reboot the machine with all defaults
  win_reboot:

- name: Reboot a slow machine that might have lots of updates to apply
  win_reboot:
    reboot_timeout: 3600

# Install a Windows feature and reboot if necessary
- name: Install IIS Web-Server
  win_feature:
    name: Web-Server
  register: iis_install

- name: Reboot when Web-Server feature requires it
  win_reboot:
  when: iis_install.reboot_required

# One way to ensure the system is reliable, is to set WinRM to a delayed startup
- name: Ensure WinRM starts when the system has settled and is ready to work reliably
  win_service:
    name: WinRM
    start_mode: delayed


# Additionally, you can add a delay before running the next task
- name: Reboot a machine that takes time to settle after being booted
  win_reboot:
    post_reboot_delay: 120

# Or you can make win_reboot validate exactly what you need to work before running the next task
- name: Validate that the netlogon service has started, before running the next task
  win_reboot:
    test_command: 'exit (Get-Service -Name Netlogon).Status -ne "Running"'
