Notes
Note
Connect to the Docker daemon by providing parameters with each task or by defining environment variables. You can define
DOCKER_HOST,DOCKER_TLS_HOSTNAME,DOCKER_API_VERSION,DOCKER_CERT_PATH,DOCKER_TLS,DOCKER_TLS_VERIFYandDOCKER_TIMEOUT. If you are using docker machine, run the script shipped with the product that sets up the environment. It will set these variables for you. See https://docs.docker.com/machine/reference/env/ for more details.This module does not use the Docker SDK for Python to communicate with the Docker daemon. It directly calls the Docker CLI program.
