chaos-wave

chaos-wave

chaos-wave will randomly kill and remove running container. Inspirted by chaos monkey form netflix.

Usage

$ docker run -v /var/run/docker.sock:/var/run/docker.sock furikuri/chaos-wave --interval 15m --duration 2h

Default interval is 10 minutes. Default duration is 1 hour.

Example usage with docker swarm service

First start a service within docker swarm.

$ docker service create --replicas=3 --name hello-docker furikuri/hello-docker

Let's observe the running containers with watch 'docker ps'.

Every 2,0s: docker ps                                                                                                                                                Sun Sep 11 12:31:50 2016

Now let's start the chaos-wave. After 30 seconds we should see the first output, which tells us that the first container has been killed.

$ docker run -v /var/run/docker.sock:/var/run/docker.sock furikuri/chaos-wave --interval 30s --duration 2h
Duration: 2h0m0s.
Interval: 30s.
Stopping container with name '/hello-docker.2.5fwbshxr1p88mcszrs1u6zdxw'

This container will be not existing in our docker ps anymore.

Every 2,0s: docker ps                                                                                                                                                Sun Sep 11 12:32:54 2016

But after a few seconds, docker swarm should start a new container.

Every 2,0s: docker ps                                                                                                                                                Sun Sep 11 12:33:01 2016
