Clusters
Magnolia PaaS runs on Kubernetes clusters. Kubernetes clusters are sets of node machines running containerized applications. One of the primary advantages of Kubernetes clusters is that they automatically manage your cluster to match the configured desired state.
| Check out the subsections below to get an idea of what the Cockpit displays for you regarding Clusters. |
Kubernetes flow
Let’s say you deploy your application with the desired state of having 4 nodes of your application running. If 1 of the nodes crashes, we see just 3 nodes are active, so we add 1 more to meet the desired state.
