Building Multi-container Architecture
Introducing Docker Compose
- a tool for defining and running multi-container Docker applications
- A single command creates and start all the services from your configuration
- Multiple isolated environments on a single host
- Preserve volume data when containers are created
- Only recreate containers that have changed
- Variables and moving a composition between environments
- Multiple isolated environments on a single host
