DOCUMENTATION = r'''
module: reboot
short_description: Reboot a machine
notes:
- E(PATH) is ignored on the remote node when searching for the C(shutdown) command. Use O(search_paths)
to specify locations to search if the default paths do not work.
description:
- Reboot a machine, wait for it to go down, come back up, and respond to commands.
- For Windows targets, use the M(ansible.windows.win_reboot) module instead.
version_added: "2.7"
options:
pre_reboot_delay:
description:
- Seconds to wait before reboot. Passed as a parameter to the reboot command.
- On Linux, macOS and OpenBSD, this is converted to minutes and rounded down. If less than 60, it will be set to 0.
- On Solaris and FreeBSD, this will be seconds.
type: int
default: 0
post_reboot_delay:
description:
- 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.
type: int
default: 0
reboot_timeout:
description:
- Maximum seconds to wait for machine to reboot and respond to a test command.
- This timeout is evaluated separately for both reboot verification and test command success so the
maximum execution time for the module is twice this amount.
type: int
default: 600
connect_timeout:
description:
- Maximum seconds to wait for a successful connection to the managed hosts before trying again.
- If unspecified, the default setting for the underlying connection plugin is used.
type: int
test_command:
description:
- Command to run on the rebooted host and expect success from to determine the machine is ready for
further tasks.
type: str
default: whoami
msg:
description:
- Message to display to users before reboot.
type: str
default: Reboot initiated by Ansible
search_paths:
description:
- Paths to search on the remote machine for the C(shutdown) command.
- I(Only) these paths will be searched for the C(shutdown) command. E(PATH) is ignored in the remote node when searching for the C(shutdown) command.
type: list
elements: str
default: ['/sbin', '/bin', '/usr/sbin', '/usr/bin', '/usr/local/sbin']
version_added: '2.8'
boot_time_command:
description:
- Command to run that returns a unique string indicating the last time the system was booted.
- Setting this to a command that has different output each time it is run will cause the task to fail.
type: str
default: 'cat /proc/sys/kernel/random/boot_id'
version_added: '2.10'
reboot_command:
description:
- Command to run that reboots the system, including any parameters passed to the command.
- Can be an absolute path to the command or just the command name. If an absolute path to the
command is not given, O(search_paths) on the target system will be searched to find the absolute path.
- This will cause O(pre_reboot_delay), O(post_reboot_delay), and O(msg) to be ignored.
type: str
default: '[determined based on target OS]'
version_added: '2.11'
