# `juju-reboot`

## Summary

Reboots the host machine.

## Usage

`juju-reboot [options]`

### Options

| Flag    | Default   | Usage                                              |
|---------|-----------|----------------------------------------------------|
| `--now` | false     | Reboots immediately, killing the invoking process. |

## Examples

```none
# immediately reboot
juju-reboot --now

# Reboot after current hook exits
juju-reboot
```

## Details

`juju-reboot` causes the host machine to reboot, after stopping all containers
hosted on the machine.

An invocation without arguments will allow the current hook to complete, and
will only cause a reboot if the hook completes successfully.

If the `--now` flag is passed, the current hook will terminate immediately, and
be restarted from scratch after reboot. This allows charm authors to write
hooks that need to reboot more than once in the course of installing software.

The `--now` flag cannot terminate a debug-hooks session; hooks using `--now` should
be sure to terminate on unexpected errors, so as to guarantee expected behaviour
in all situations.

`juju-reboot` is not supported when running actions.
