KubeCon is veritably a festival for the tech community nowadays, and this is a sentiment that I have expressed several times before, but cannot tire of repeating! The sheer diversity of content (organized into a neat set of tracks), the announcements & launches, predictions, and panel discussions, all add to the excitement. I even managed to get my young nephew interested in the Cloud Native world by ordering the Phippy & friends buildable set with my Speaker giveaway!

For us, as members of the LitmusChaos project & the broader cloud native chaos engineering community, this edition of Kubecon EU '21 turned out to be sweeter still.

The predictions made ahead of the event by Cheryl Hung, VP, Ecosystem at CNCF, where she noted the growing interest in chaos, set the ball rolling (and this came on the back of similar observations made by Liz Rice, the chair of CNCFs Technical Oversight Committee (ToC) at the November 2020 Kubecon):

This added to the organic interest that Litmus as a project has gathered in the CNCF community, and resulted in some wonderful responses to the various presentations/talks that it featured in. All this led to newer slack members, appreciative messages from those that grokked the project, more questions on whats coming & roadmap, quick feedback from folks that tried it, and some cool issues and PRs in the process!

In this blog post, let us do a quick round-up of the talks/sessions where Litmus appeared. Some of the perspectives expressed are instructive and definitely hold value for us at the project. I have also tried to capture all the buzz (via tweets, of course) around Litmus and provide links to the awesome presentations around the project.

The Round-Up

First up, was the whirlwind sandbox projects tour by Justin Cormack, CTO, Docker, where he introduced Litmus as a way to package & perform your own custom chaos experiments. The talk prompted some awesome cloud-native advocates & tech-gurus to recall some deep dives on the project that had been performed in recent times!

This year we've been taking a deep dive into the CNCF Sandbox on our blog, and so far we've covered @kubevirt, @LitmusChaos and @telepresenceio. But @justincormack just blew us out of the water running through all 50 projects in 15min! #KubeConhttps://t.co/qh9eVE4q3N

Our KubeCon talk, on Putting Chaos into Continuous Delivery to increase Application resilience along with the fantastic team at Keptn, was well attended with many questions on the philosophy of automated chaos. For those interested, there is more coming on the integration with Keptn, including some very cool use cases around auto-remediation!

Key takeaways from the talk!
Glad to have @KitopiHQ as an adopter of both @keptnProject & @LitmusChaos.

Alois Reitbauer (https://twitter.com/AloisReitbauer), co-chair of the CNCF SIG-App Delivery, presented some interesting findings in this space, with Chaos Engineering & Litmus getting special mention. He discussed some common experimentation trends, and how organizations are embracing a shift left approach with chaos. And what better than validation of these thoughts from the experts at Gitlab!

Next up was probably the most interesting demo (one that followed a nice intro/whiteboard session) involving litmus in the Kubecon. Saiyam (Civo) & Karthik (Verica) presented how one could leverage the GitOps & Event-triggered chaos features in the Litmus platform to test the sanity of the changes made to your application deployments on the cluster. It also had some cool takeaways on how you should approach chaos engineering & up your reliability game.

In between the various talks, we had the opportunity to hold the Office Hours (thanks a ton to the CNCF for organizing this) where community members, first time users got a chance to learn about the project & the advanced ones to probe us on the roadmap :). What better than waking up to messages like this from folks that attended the office hours:

#Chaos @LitmusChaos was a big surprise for me in #kubeconEU. They have an excellent solution for controlled and scheduled chaos validation in production environments for many services running on K8s. Great solution for Disaster Recovery and self healing tests

Amidst all this, we had our SIG-Docs lead @Divya_Mohan02 participating in the awesome DoKC Day (Data on Kubernetes Community), where she shared her contribution journey in LitmusChaos, what it means to break things intentionally & how folks can get involved with the project.

Looking Ahead

While we feel chaos engineering & LitmusChaos projects approach towards it has been validated, there is much work to do & improve. The impending Litmus 2.0 launch is expected to improve the experience of users along with a host of useful features. Having said that, What are the aspects you are most interested in seeing Litmus get better at, features youd like to include or integrations youd like to see?
