Calico Open Source 2022 highlights

2022 has been a year full of new releases, new events, and new projects for Open Source Calico. Let’s take a look at Project Calico’s 2022 highlights and see if you’ve missed any exciting news.

Calico education and training

The newest addition to our series of free, self-paced courses is the Certified Calico operator: Azure Expert! If you are not familiar with the previous courses, I highly recommend enrolling in them in the following order:

  2. Certified Calico Operator: AWS Expert
  3. Certified Calico Operator: eBPF

The Certified Calico Operator: Azure Expert course introduces Azure cloud, learnings about managed, self-managed, and hybrid cluster deployment using Calico in Azure, and offers hands-on labs to help you explore the features in the Calico–Azure integration. For more information about the course curriculum, check out this blog post on the Calico Azure course.

Calico Community

From KubeCon 2022 to meet-ups, the Calico community has been very active in the past year. With the support of our ambassadors and our team, we were able to collaborate and team up with Calico users all around the world.

Ambassador program and new blog series

In the beginning of 2022, we launched Calico Big Cats, which is an ambassador program created to provide a platform for our community to talk about their experiences with Calico. Since our launch, we have over 60 Big Cats representing Project Calico. We also launched the Community Spotlight series to interview our community members and learn more about their Kubernetes journey. Big shoutout to all our Calico Big Cats and our much-appreciated community for supporting Calico!


We collaborated with multiple meet-up groups that are dedicated to learning about Kubernetes and Kubernetes security. We were also onstage at KubeCon NA 2022 to present Opening the Black Box: Understanding and Troubleshooting Calico’s eBPF Dataplane and became a part of the suggested tools for platform engineers on the Platform Engineers website. And finally, we also hosted CalicoCon and Cloud Native Security Summit 2022, which was filled with open-source user stories from our Calico Big Cats and informative sessions delivered by Tigera partners and customers.

Open source news

Did you know Calico was mentioned in Datadog’s report, “9 insights on real-world container use,” as one of the most popular container images? Calico was described as  “a networking provider that lets administrators manage the security of the network within their Kubernetes clusters.”

Last but not the least, we now have a monthly community digest dedicated to open source news! If you’d like to get updates monthly, then subscribe to the Calico Open Source Community Newsletter.

A big thank-you to our community

2022 has been an impactful year for Project Calico and its community. With the help of our contributors and Calico Big Cats, we’ll continue to grow the project and extend our reach to new collaborations. Thank you, everyone, for supporting us and being a part of the Calico community.

Feel free to take part in our next monthly community meeting, where we discuss the future of Calico Open Source and spotlight community members who might have made some of the favorite features you are currently using.
