Get an overview of the GitOps principles and learn why they are essential for new IT projects in this excerpt from the GitOps Cookbook.

With the introduction of new security context constraints, pods must be properly configured under the enforced security standards defined globally or on a namespace level to be admitted to launch. Learn how Cryostat Operator 2.2.0 accommodates these changes.

When deployed on Kubernetes or OpenShift, Cryostat uses a default permission configuration that maps Kubernetes resources to Cryostat-managed resources to authorize a user to perform certain actions. Since a single set of mappings does not always fit all, with Cryostat Operator 2.2.0, we allow this mapping to be configurable via the Cryostat custom resource.
