CHAPTER 1 | Introduction to Containers and Docker
you can deploy the whole multi-container application with a single command (docker-compose up)
that creates a container per image on the Docker host.
Cluster
: A collection of Docker hosts exposed as if it were a single virtual
Docker host, so that the
application can scale to multiple instances of the services spread across multiple hosts within the
cluster. Docker clusters
can be created with Kubernetes, Azure Service Fabric,
Docker Swarm and
Mesosphere DC/OS.
