reboot – Reboot a machine

New in version 2.7.

Synopsis

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

Parameters

Parameter Choices/Defaults Comments
connect_timeout
integer
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.
msg
string
Default:
"Reboot initiated by Ansible"
Message to display to users before reboot.
post_reboot_delay
integer
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.
pre_reboot_delay
integer
Default:
0
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.
reboot_timeout
integer
Default:
600
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.
test_command
string
Default:
"whoami"
Command to run on the rebooted host and expect success from to determine the machine is ready for further tasks.
