Apocalypso is resilience test tool to test the behaviour of Docker Ecosystem under various failure conditions (Network/hardware/termination etc)
Inspired by the following projects (code attributions provided at necessary place :P)
$ python setup.py sdist
$ easy_install dist/apocalypse-<version>.tar.gz
or
$ pip install git+https://github.com/dhoomakethu/apocalypso.git@master
For Colored logs install coloredlogs
$ pip install git+https://github.com/dhoomakethu/python-coloredlogs.git@master
To use with docker eco system as a container wiki
$ doom --help

Chaos Generator for Docker Ecosystems!!
version: 1.0.0
usage: doom {chaos|events|server} <optional params>
positional arguments:
{chaos,events,server}
help for subcommand chaos
chaos Start Chaos generator
events Chaos events
server Chaos web server
optional arguments:

There are three subparsers defined chaos and actions.
$ doom chaos --help
usage: doom chaos <optional params>
optional arguments:
--start Start Chaos Generator (default: False)
--stop Stop Chaos Generator (default: False)
--status status of chaos generator (default: False)
-e EVENTS [EVENTS ...], --events EVENTS [EVENTS ...]

Sec/Minute/Hour) (default: None)
--max-workers MAX_WORKERS
Max worker threads to spawn (default: None)
--enable-network-chaos
enables network chaos (default: False)
--run-network-chaos Runs only network chaos (default: False)
--run-resource-chaos Runs only resource chaos (burn cpu/ram/kill process
etc) (default: False)
--run-generic-chaos Runs only generic chaos (stop/reboot/terminate
containers (default: False)
--version show program's version number and exit
$ doom events --help
usage: doom events <optional params>
optional arguments:
--list-events List available chaos events supported (default: False)
--all display all defined chaos events (default: False)
--version show program's version number and exit
$ doom server --help
usage: doom server <optional params>
optional arguments:
--host HOST HOST IP to run the chaos web server on (default: localhost)
--port PORT PORT to run the chaos web server on (default: 5555)
--version show program's version number and exit
NOTE: All below examples assumes the docker eco system under test is up and running and has a valid docker network associated with
##To Start Chaos Webserver ##
$ doom server --port <PORT to START>
If no arguments are passed , by default the server will start on localhost:5555 with default docker network as apocalypso_default ##To Start Chaos on network abc##
$ doom chaos --start --network abc --events stop kill burncpu
