Hey Jon, * What aspects of Mission Control are dependent on using K8ssandra? >
Mission Control bundles in K8ssandra for the core automation workflows (lifecycle management, cluster operations, medusa &. reaper). In fact we include the K8ssandraSpec in the top-level MissionControlCluster resource verbatim. * Can Mission Control work without K8ssandra? Not at this time, K8ssandra powers a significant portion of the C* side of the stack. Mission Control provides additional functionality (web interface, certificate coordination, observability stack, etc) and applies some conventions to how K8ssandra objects are created / templated out, but the actually K8ssandra operator present in MC is the same one available via the Helm charts. * Is mission control open source? > Not at this time. While the majority of the Kubernetes operators are open source as part of K8ssandra, there are some pieces which are closed source. I expect some of the components may move from closed source into K8ssandra over time. * I'm not familiar with Vector - does it require an agent? Vector <https://vector.dev/> is a pretty neat project. We run a few of their components as part of the stack. There is a DaemonSet which runs on each worker to collect host level metrics and scrape logs being emitted by containers, a sidecar for collecting logs from the C* container, and an aggregator which performs some filtering and transformation before pushing to an object store. * Is Reaper deployed separately or integrated in? > Reaper is deployed as part of the cluster creation workflow. It is spun up and configured to connect to the cluster automatically. ~Chris Christopher Bradford On Tue, Feb 27, 2024 at 6:55 PM Jon Haddad <j...@jonhaddad.com> wrote: > Hey Chris - this looks pretty interesting!
