[FEATURE REQ] The context of Azure CLI and the environment variables cannot be shared in Docker container

[moarychan]

Context

The current samples are using Terraform to create and destroy Azure resources based on Azure CLI authentication, then output the environment variables to share the configuration of the Azure resources.
But when running in the docker containers, the application will fail because it can't get environment variables and Azure CLI information.

Goal

Make it successfully to run samples for the docker users. It could be a guide or work out of the box.
