DoK Day EU 2022 @ KubeCon was an engaging and fun day for our early onsite team members. We chose to attend the virtual event in person to do our presentation and to meet the DoK team and attend the after party. It was a full day with 47 speakers sharing their knowledge on how to do Data on Kubernetes (DoK) well, along with musical interludes for over 2,800 virtual guests! And for those of us who attended in person, a follow-on cocktail party with more music and more entertainment from Bart Farrell.

Running stateful workloads on Kubernetes is gaining traction, but there are many challenges. Multiple clusters exist in most Kubernetes environments today, and the number of clusters are increasing over time. The reasons for having multiple Kubernetes clusters are many, for example, overcoming scale limits, reducing complexity, geo separation, redundancy and having separate production, staging, and development environments. Once you have multiple Kubernetes clusters, it can be useful to have the ability to easily move or duplicate workloads across these different clusters. Kubernetes does not have a native method to allow migration or duplication of workloads across clusters.
