This API is used to provision application instances on a cluster. KubePlus isolates each application instance in a separate namespace. It adds a safety perimeter around such namespaces using Kubernetes network policies and non-shared persistent volumes ensuring that each application instance is appropriately isolated from other instances. Additionally, it provides controls for application providers to deploy different tenant application instances on different worker nodes for node isolation. - ### Security The KubePlus Operator does not need any admin-level permissions on a cluster for application providers. This allows application providers to offer their managed services on any K8s clusters including those owned by their customers. KubePlus comes with a small utility that allows you to create provider specific kubeconfig on a cluster in order to enable application deployments and management. Providers have an ability to create a consumer specific further limited kubeconfig to allow for self-service provisioning of application instances as well. -### Resource utilization + +### Resource Utilization KubePlus provides controls to set per-namespace resource quotas. It also monitors usage of CPU, memory, storage, and network traffic at the application instance level. The collected metrics are available in different formats and can be pulled into Prometheus for historical usage tracking. KubePlus also supports ability to define licenses for the CRDs. A license defines the number of application instances that can be created for that CRD, and an expiry date. KubePlus prevents creation of application instances if the license terms are not met. @@ -43,23 +43,28 @@ The spec properties of the Kubernetes CRD wrapping the application Helm chart ar ## Installation -### Manual steps +### Manual Installation Steps -* Create cluster or use an existing cluster.
