Pumba: Chaos testing tool for Docker



You can download Pumba binary for your OS from release page.

$ pumba help

   Pumba - Pumba is a resiliency tool that helps applications tolerate random Docker container failures.

   pumba [global options] command [command options] [arguments...]


    run  Pumba starts making chaos: periodically (and randomly) kills/stops/remove specified containers

   --host, -H "unix:///var/run/docker.sock"  daemon socket to connect to [$DOCKER_HOST]
   --tls                                     use TLS; implied by --tlsverify
   --tlsverify                               use TLS and verify the remote [$DOCKER_TLS_VERIFY]
   --tlscacert "/etc/ssl/docker/ca.pem"      trust certs signed only by this CA
   --tlscert "/etc/ssl/docker/cert.pem"      client certificate for TLS authentication
   --tlskey "/etc/ssl/docker/key.pem"        client key for TLS authentication
   --debug                                   enable debug mode with verbose logging
   --json                                    produce log in JSON format: Logstash and Splunk friendly
   --slackhook                               Slack web hook url. Send Pumba log events to Slack
   --slackchannel "#pumba"                   Slack channel for Pumba log events

   --version, -v                             print the version
$ pumba run --help

   pumba run - Pumba starts making chaos: periodically (and randomly) kills/stops/remove specified containers

   pumba run [command options] [arguments...]

   --chaos, -c [--chaos option --chaos option]    chaos command: `container(s,)/re2:regex|interval(s/m/h postfix)|STOP/KILL(:SIGNAL)/RM`
   --random, -r                    Random mode: randomly select single matching container to 'kill'

Runing inside Docker container

If you choose to use Pumba Docker image on Linux, use the following command:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock gaiaadm/pumba pumba run --chaos "re2:^hp|10s|KILL:SIGTERM"

The above command, once in a 10 seconds, tries to kill (with SIGTERM signal) all containers named hp(something) on same Docker host, where Pumba container is running.

Note: For Windows and OS X you will need to use --host argument, since there is no unix socket /var/run/docker.sock to mount.

Running Pumba on Kubernetes cluster

If you are running Kubernetes >= 1.1.0. You can take advantage of DaemonSets to automatically deploy the Pumba on all your nodes.
On 1.1.x you'll need to explicitly enable the DaemonSets extension, see

You'll then be able to deploy the DaemonSet with the command

$ kubectl create -f pumba_kube.yml

If you are not running Kubernetes >= 1.1.0 or do not want to use DaemonSets, you can also run the Pumba as a regular docker container on each node you want to make chaos (see above)

Running Pumba on CoreOS cluster

If you are running CoreOS cluster. You can use fleetctl command to deploy Pumba service file on every CoreOS cluster node.
You'll then be able to deploy the Pumba service with the command

$ fleetctl start pumba_coreos.service

Build instructions

You can build Pumba with or without Go installed on your machine.

Build using local Go environment

In order to build Pumba, you need to have Go 1.6+ setup on your machine.

Here is the approximate list of commands you will need to run:

mkdir && cd
git clone
cd pumba
glide install
go build -v

Build using Docker builder image

You do not have to install and configure Go in order to build and test Pumba project. Pubma builder Docker image contains Go 1.6 and all tools required to build and test Pumba.

First of all clone Pumba git repository:

git clone
cd pumba

Now create a Pumba builder Docker image.

docker build -t pumba/builder -f Build.Dockerfile .

Now you can use pumba/builder to build, test (with coverage) and deploy Pumba.

To build a new Pumba binary run the following command:

docker run --rm -v "$PWD":/go/src/ -w /go/src/ pumba/builder script/

To build new Pumba binaries for multiple platforms run the following command (using gox tool):

docker run --rm -v "$PWD":/go/src/ -w /go/src/ pumba/builder script/

To run all Pumba tests and generate coverage report run the following command:

docker run --rm -v "$PWD":/go/src/ -w /go/src/ pumba/builder script/ --html

Used Libraries and Code

I've also borrowed a code from very nice CenturyLinkLabs/watchtower project.


Code is under the Apache Licence v2.
