Docker Compose: Docker Configuration for the Real World
Download as PPTX, PDF0 likes655 views
Docker Compose simplifies the management of multi-container applications by allowing users to store and manage configurations in YAML format. Initially created as a separate project called Fig, it was acquired by Docker and has since become an integral part of the Docker toolset. The document also provides a brief overview of using Docker Compose commands and links to various demo stacks and additional resources.
![How it works
● Written in YML
● Uses similar terms to Docker on command line
● Run using $ docker-compose [something]](https://image.slidesharecdn.com/dockercomposedockerconfigurationfortherealworld-180523105214/85/Docker-Compose-Docker-Configuration-for-the-Real-World-6-320.jpg)
