A Chaos Engineering toolkit.

chaosd

Chaosd is an easy-to-use Chaos Engineering tool. This tool is used to inject failures to the physic node, such as kill process, network failure, CPU burn, memory burn and etc.

Prerequisites

Before deploying Chaosd, make sure the following items have been installed:

• tc
• ipset
• iptables
• stress-ng

Install

Build from source code

make chaosd
chmod +x chaosd && mv chaosd /usr/local/bin/chaosd

Download binary

curl -fsSL -o chaosd https://mirrors.chaos-mesh.org/latest/chaosd
chmod +x chaosd && mv chaosd /usr/local/bin/chaosd

Usage

Process attack

• kill process

$ chaosd attack process kill -p [pid] # set pid or pod name
# remember the generated uid, we need this uid to recover chaos attack
Attack network successfully, uid: 2c865e6f-299f-4adf-ab37-94dc4fb8fea6

• stop process

$ chaosd attack process stop -p [pid] # set pid or pod name

Network attack

• delay network packet

$ chaosd attack network delay -d eth0 -i 172.16.4.4 -l 10ms

• loss network packet

$ chaosd attack network loss -d eth0 -i 172.16.4.4 --percent 50%

• corrupt network packet

$ chaosd attack network corrupt -d eth0 -i 172.16.4.4 --percent 50%

• duplicate network packet

$ chaosd attack network duplicate -d eth0 -i 172.16.4.4 --percent 50%

Stress attack

• CPU stress

$ chaosd attack stress cpu -l 100 -w 2

• Memory stress

$ chaosd attack stress mem -w 2 # stress 2 CPU and each cpu loads 100%

Recover attack

$ chaosd recover 2c865e6f-299f-4adf-ab37-94dc4fb8fea6
