As promised, we are back with another edition of monthly updates from the LitmusChaos community. With the growth of the Chaos Engineering community as well as the LitmusChaos community, we appreciate this massive participation and immense engagement and strive for the community to prosper and contribute back to its development.

This article is written to share monthly updates with the community from August 2022 

to update the community on the latest happenings and updates around the LitmusChaos project.

About LitmusChaos

LitmusChaos is a dynamic open source chaos engineering platform that enables teams to identify weaknesses and potential outages in infrastructures by inducing chaos engineering tests/experiments in a controlled manner. LitmusChaos is driven by the principles of Cloud-Native innovation and gave rise to the principles of Cloud-Native Chaos Engineering. Chaos engineering verifies the resilience of business services and helps DevOps pipelines proactively build code that is more resilient against software and infrastructure faults.
The LitmusChaos project was started in late  2017 to provide simple chaos jobs in Kubernetes. It became a CNCF sandbox project in 2020 and was promoted as a CNCF incubating project in January 2022. Today, it has maintainers from 5 different organizations across cloud-native vendors, solution providers, and end-users. 

The project is used in production by more than 30 organizations, including large end-users like Adidas, FIS, iFood, Cyren, Intuit, Lenskart, Orange, and more as well as technology organizations like Red Hat and VMware.

User Stories:

Here is a sneak-peek into the adopter story presented by CI&T as well as AB-Inbev on how they are using LitmusChaos:

ABInBev
CI&T

After an evaluation period of some Chaos Engineering tools, we chose LitmusChaos because it is a more mature tool that would meet most of our needs. We are in the implementation, configuration, and process definition phase.

AB-Inbev’s BEES is a huge project that has hundreds of microservices, it has been a great challenge to adapt Litmus in this process, making customizations and counting on the help of the Litmus community to evolve the tool and thus achieve our goal of making it available to the teams.

Some points that made us choose Litmus:

Community Content –

As the community continues to grow, so does the content. Over the month the community members have created some amazing and exciting content to uplift the presence of LitmusChaos on the Cloud Native map. Check out all the latest content curated by the community for the community:

Chaos Engineering Meetup:

To inculcate the knowledge of Chaos Engineering, we kick started the initiative of organizing Chaos Engineering Meetups every month to talk about all things Chaos Engineering and move beyond the scope of LitmusChaos to give the community an opportunity to learn principles, concepts and larger ideas around chaos.

In the last edition of the Chaos Engineering Meetup, we had the core contributors of the LitmusChaos project from Harness share some amazing insight into the Litmus SDK as well as the latest HTTP chaos experiments. Here’s an overview of the agenda:

Topic – Bring Your Own Chaos With Litmus SDK by Shubham Chaudhary

Description – If you are looking for a SDK to generate a custom chaos experiment then Litmus SDK can help you. In this talk we will explain the process to generate a new custom chaos experiment with Litmus SDK.

Topic: HTTP Chaos using LitmusChaos by Akash Srivastava

Description: If you want to test how your application will handle broken APIs or incorrect data, HTTP Chaos is here. This talk will cover HTTP experiments that can modify the response status code or the response body or header. Followed by a live demo on a simple application.

Community Meeting:


The LitmusChaos Community meetings continue as a monthly cadence call to discuss the latest updates, happenings, and questions from the community. They are hosted every 3rd Wednesday of the month.  Check out the latest from our last community meeting held on August 17th.
