This document introduces how to simulate host shutdown faults using Chaosd.

View the help information of host shutdown experiments

Before creating a fault experiment, you can run the following command to view the help information of host shutdown experiments:

chaosd attack host shutdown -h

The output is as follows:

shutdowns system, this action will trigger shutdown of the host machine

Usage:
  chaosd attack host shutdown [flags]

Flags:
  -h, --help   help for shutdown

Global Flags:
      --log-level string   the log level of chaosd, the value can be 'debug', 'info', 'warn' and 'error'

Create a host shutdown experiment

To create a host shutdown experiment, run the following command:

chaosd attack host shutdown

The example output is as follows:

chaosd attack host shutdown
Shutdown successfully, uid: 4bc9b74a-5fe2-4038-b4f3-09ae95b57694

After executing this command, your host will shut down after all processes are closed.
