Docker Compose
Understand how Docker Compose simplifies managing multi-container Docker applications by enabling you to define, run, and scale services using a single configuration file. Learn installation, creation of docker-compose.yml, and commands to start, stop, and scale containers.
Benefits of Docker
Before learning more about Docker’s features, let’s discuss the benefits of Docker first.
- Docker makes deployment of our application a lot easier by packing the software and its dependencies in a container.
- We need to build our application only once, without needing to build or configure it on multiple environments.
- Once we upload our image in Docker Hub, a public registry to store docker images, we can pull the image in any environment. Our application will work fine because we’re running them in identical containers.
- Docker allows us to do image versioning.
- Docker containers work in isolated environments. They do not interfere with other containers running on the same system.
