= The conditions are sufficient for Kubernetes to dynamically provision a persistentVolume, because a storageClass defines the provisioner and parameters for creating a volume on-demand. A persistentVolumeClaim that specifies a storageClass triggers the dynamic provisioning process, and Kubernetes will automatically create and bind a persistentVolume that matches the request. This eliminates the need for manual intervention by cluster administrators to provision storage volumes. References:

Image role-based access control is not a function of UCP. UCP has its own built-in authentication mechanism and integrates with LDAP services. It also has role-based access control (RBAC), so that you can control who can access and make changes to your cluster and applications1. However, image role-based access control is a feature of Docker Trusted Registry (DTR), which integrates with UCP and allows you to manage the images you use for your applications2. DTR lets you define granular permissions for images, such as who can push, pull, delete, or scan them3. References: Universal Control Plane overview), Docker Trusted Registry overview), Docker Access Control)

 Multi-stage builds are a feature of Docker that allows you to use multiple FROM statements in your Dockerfile. Each FROM statement creates a new stage of the build, which can use a different base image and run different commands. You can then copy artifacts from one stage to another, leaving behind everything you don’t want in the final image. This optimizes the image size and reduces the attack surface by removing unnecessary dependencies and tools. For example, you can use a stage to compile your code, and then copy only the executable file to the final stage, which can use a minimal base image like scratch. This way, you don’t need to include the compiler or the source code in the final image. References:
