David Flanagan shares his experiences of fixing 100 broken Kubernetes clusters in a presentation. He founded Rockwood Academy, a platform that initially started as a YouTube channel and later transformed into a full-time venture focusing on cloud-native software. David hosts a show called "Clustered" where he takes on the challenge of fixing compromised Kubernetes clusters. Through this show, he emphasizes the importance of learning from failures to better understand system operations. Additionally, David discusses various tools and techniques related to Kubernetes and Linux, such as eBPF, and recommends their usage for enhanced system operation and monitoring.
