PowerfulSeal - a powerful testing tool for Kubernetes clusters

PowerfulSeal

PowerfulSeal adds chaos to your Kubernetes clusters, so that you can detect problems in your systems as early as possible. It kills targeted pods and takes VMs up and down.

Embrace the inevitable failure. Embrace The Seal.

It follows the Principles of Chaos Engineering, and is inspired by Chaos Monkey. Watch the Seal at KubeCon 2017 Austin.

• web interface to interact with PowerfulSeal
• metric collection and exposition to Prometheus or Datadog

FAQ

Where can I learn more about Chaos Engineering ?

We found these two links to be a good start:

• http://principlesofchaos.org/
• https://github.com/dastergon/awesome-chaos-engineering

How is it different from Chaos Monkey ?

PowerfulSeal was inspired by Chaos Monkey, but it differs in a couple of important ways.

The Seal does:

• speak Kubernetes
• offer flexible, easy to write YAML scenarios
• provide interactive mode with awesome tab-completion

The Seal doesn't:

• need external dependencies (db, Spinnaker), apart from SSH, cloud and Kubernetes API access
• need you to setup cron

Can I contribute to The Seal ?

We would love you to. In particular, it would be great to get help with:

• get more cloud drivers
• get more awesome filters
• get an amazing logo
• make the PowerfulSeal more powerful

Check out our contributing page for more information about how to contribute.

Why a Seal ?

It might have been inspired by this comic.
