SM studio - Docker CLI installation for private VPC accounts without internet

We are a part of studio account owners who are trying help our customers use the newly enabled [localmode in SM studio](https://docs.aws.amazon.com/sagemaker/latest/dg/studio-updated-local.html) for running our training and processing jobs. However since SM Studio localmode also requires installing [docker-ce-cli](https://docs.docker.com/engine/install/ubuntu/) and its corresponding dependencies, and our studio environment does not have internet access, installing docker does not seem straightforward. We cannot enable internet access due to security reasons, which means that its not possible for us to use SM Studio localmode features inside our private VPC.

Start with the linked SageMaker Studio localmode documentation and the docker-ce-cli installation requirements for Ubuntu. Investigate how Docker CLI and its dependencies could be made available in private VPC environments without internet access, then define completion as successful localmode use for training and processing jobs under those constraints.
