This list of target namespaces may also optionally include the installation namespace, if you want Cryostat to be able to discover its own components as applications to be monitored. This is still done in the Cryostat conventional way of querying for Kubernetes Endpoints objects that have a port with either the name jfr-jmx or the number 9091. The target namespaces of a ClusterCryostat are simply those namespaces within which the Cryostat instance attempts to discover target applications. This namespace should be separate from the target application(s), ideally reserved for the ClusterCryostat instance alone, and RBAC permissions within this installation namespace are how administrators can control which users have access to the instance. for Cryostat and its associated components. The installation namespace of a ClusterCryostat is straightforward - it is the namespace ( OpenShift Project) into which the Cryostat Operator will create a Deployment, Service, etc.

The Cryostat Operator will warn the user and fail the deployment if there is a collision between a Cryostat CR namespace and the installation namespace or target namespaces of any ClusterCryostat CR. The old Cryostat CR is still available and is used for creating single-namespace Cryostat instances. In order to deploy a new multi-namespace-enabled instance, users can create a new ClusterCryostat Custom Resource ( CR) in OCP after installing or updating the Cryostat Operator.

When deploying a multi-namespace Cryostat instance, administrators must be careful and considerate about which projects to select for monitoring, which project to install Cryostat into, and which users to grant access. What this means is that any user who can access the Cryostat instance has access to all target applications in any project visible to that Cryostat instance. Cryostat 2.3 can be deployed such that it discovers target applications in multiple projects, but it does not silo the data. * Kubernetes Namespaces are referred to as Projects in OpenShift Container Platform (OCP).īefore I continue, there is an important caveat to be aware of with this initial support. This is the first half of multi-tenant support in Cryostat. With this release it is now possible to deploy a single Cryostat instance for monitoring and profiling Java application instances across all of your OpenShift projects, whereas previous Cryostat releases required you to deploy one Cryostat instance into each project. Cryostat 2.3 includes another popular community-requested feature: multi-namespace support*.
