Which of the following is required to install Docker EE from a package repository?

Docker Enterprise Edition (EE) is a commercial product requiring a subscription, and its package repositories are private. Accessing these repositories for installation necessitates a specific Repository URL provided by the vendor, which was historically obtained through the Docker Store.

While a license is essential for Docker EE, the license key itself does not directly provide the package repository URL for initial installation; access to the repository is typically tied to the subscription.

Docker Hub is primarily for storing and sharing Docker images and does not host the package repositories for installing Docker EE components.

Similar to option B, a license key from Docker Hub would not grant access to the Docker EE installation package repository, as Docker Hub is an image registry.
