The creation of a docker group allows you to run Docker without the sudo command. sudo apt-get install -y apparmor docker-engine Install the Application Armar and Docker Enginee. sudo apt-get install -y linux-image-extra-$(uname -r) This is useful for setting up reoccuring services that are use often and/or have complex configurations. sudo apt-get updateĪdd docker to the cache to speed up subsequent access. Docker Compose is an alternate CLI frontend for the Docker Engine, which specifies properties of containers using a docker-compose.yml YAML file rather than, for example, a script with docker run options.
