Setup

Docker architecture

• Docker is a client-server application
• The Docker daemon (or “Engine”)
  • Receives and processes incoming Docker API requests
• The Docker client
  • Talks to the Docker daemon via the Docker API
  • We’ll use mostly the CLI embedded within the Docker binary
• The Docker Hub Registry
  • Is a collection of public images
  • The Docker daemon talks to it via the registry API

The Docker installation will install the Docker daemon and client on your workstation.
