Description

Currently, it is tedious to execute Docker related operations due to the plumbing needed to define the DockerCommand, writing the command file, configuring privileged operation, and finally executing the command and validating the result. Obtaining the current status of a Docker container can also be improved. Finally, the test coverage is lacking for Docker Commands.
