TCP 5.0.1 now ships with Harbor 2.10.2. This version is based on a Cloud Native solution and is deployed as a CNF. You can find more details on its deployment and configuration
here.
In contrast, Harbor 2.6.3 was originally intended for TCP 3.0. This is a VM-based solution where the customer is responsible for providing their own Photon or Linux VM. Since the VM and its operating system shell are not provided by VMware (Broadcom), the security of these components falls under the customer's responsibility.
