Thanks for the PR! Could you please move it under examples/vxc instead of Docker, and create_my_package_container.sh under scripts while renaming it to create_vxc_container.sh. I don't think this script is my_package specific. Does this script really create a container as it is stated in its name?

├── examples
│   └── vxc
│      ├── my_package - VxWorks ROS2 container examples
│         ├── Dockerfile
│         └── README.md
├── scripts
│   └── create_vxc_container.sh

I have refactored folder structure according to the review comment. Regards "Does this script really create a container as it is stated in its name", the answer is it creates container payload, so I have renamed it to be more precise.

I have addressed all points. Please take a look. Thanks for findings.
