Chaos is used to check the distributed system linearizability.

Chaos is inspired byjepsen and usesporcupine as its linearizability checker.

Chaos runs your registered database on 5 nodes, sends the command throughssh to control the service, like starting/stoping the service, or using a nemesis to disturb the whole cluster.

In one shell, we start the 5 nodes and the controller.

cd docker./up.sh

In another shell, usedocker exec -it chaos-control bash to enter the controller, then:

# build the node and your own chaos testmake# run you own chaos like./bin/chaos-tidb

It is very easy to write your own chaos test. TODO...
