Docker Compose is a service that allows you to run several containers as one. Each of the containers here runs in isolation, but they can communicate with one another if necessary.
The scripting language YAML, which stands for Yet Another Markup Language and is based on XML, makes writing Docker Compose files a breeze. Another great thing about Docker Compose is that users can activate all the services (containers) using a single command.
Here are the benefits of using docker compose:
- Single host deployment – This means you can run everything on a single piece of hardware
- Quick and easy configuration – Due to YAML scripts
- High productivity – Docker Compose reduces the time it takes to perform tasks
- Security – All the containers are isolated from each other, reducing the threat landscape
