KubeCrash is a new event designed for those unable to attend KubeCon, offering live crash courses and sessions on cloud native technology led by maintainers of prominent open source projects. Organized by five open source companies, the event focuses on delivering high-quality content without vendor pitches, covering projects like Linkerd, cert-manager, CockroachDB, Pulumi, Polaris, and Goldilocks. With Kubernetes as a central tool for cloud-hosted application development, KubeCrash aims to enhance knowledge sharing among developers, reliability engineers, cloud security specialists, and platform engineers. The program includes workshops on implementing zero-trust environments using cert-manager, facilitating multi-cluster failover with Linkerd, optimizing Kubernetes workloads with Polaris and Goldilocks, delivering serverless services using Kubernetes, and cloud engineering with Pulumi across multiple cloud providers. The event promises actionable insights on topics such as scalable zero-trust, cloud-native security, and serverless multi-cloud deployments, ensuring attendees gain practical understanding and skills directly from the experts.
