docker-machine, docker-compose, docker-swarm 覚書
The document discusses several new Docker tools: Docker Machine, Docker Compose, and Docker Swarm. Docker Machine allows automatically provisioning Docker environments on platforms like EC2, DigitalOcean, Azure and VirtualBox. Docker Compose defines and runs multi-container Docker applications. Docker Swarm turns a pool of Docker hosts into a single, virtual Docker host. Examples are provided for deploying containers to DigitalOcean using Docker Machine and running multi-container apps with Docker Compose.
