Hello World

This is the most basic example available for using Docker.

Download the base container

# Download a base image
docker pull base

The base image is a minimal ubuntu based container, alternatively you can select busybox, a bare minimal linux system. The images are retrieved from the docker repository.

#run a simple echo command, that will echo hello world back to the console over standard out.
docker run base /bin/echo hello world

Explanation:

• "docker run" run a command in a new container
• "base" is the image we want to run the command inside of.
• "/bin/echo" is the command we want to run in the container
• "hello world" is the input for the echo command
