Docker: Hello World

docker run hello-world

The installation message details what Docker is doing:

  1. Docker client contacted Docker daemon
  2. Docker daemon pulled the “hello-world” image from the Docker Hub (after checking locally)
  3. The Docker daemon created a new container from that image which runs the executable that produces the installation message output  (i.e. 1 to 4)
  4. Docker daemon streamed the output to the Docker client which sends it to the terminal
