What is Docker and Docker Compose

Docker is an effective platform that allows you to develop, deploy and run applications, it does this by containerizing applications. Containers on the other hand are isolated environments that package up an application code, runtime, system tools and system libraries required to run an application. Thus, making it easy to move applications on different platforms without worrying about any compatibility issue. On the other hand, Docker Compose is a tool used to run multi-containers Docker applications, and it allows you to define your application services and their dependencies in a yaml file.

Why We Need Docker and Docker Compose

Having a Docker and Docker Compose installed on the system will make it easier to deploy, develop and run applications. They are popular choices for developing and deploying web applications, or running machine learning based models. With Docker and Docker Compose, a developer can easily create a containerized development environment having all the tools and dependencies required to run an application. Multiple containers can easily be deployed on a single command, thus save developers time in running multiple commands. They can also become useful to create a containerized environment specially to run machine-learning models.

Why Docker and Docker Compose is Useful for Raspberry Pi

Docker and Docker Compose is a useful choice for Raspberry Pi since the applications developed from Docker are cost effective and efficient. They are also lightweight, thus consuming less Raspberry Pi CPU resources. Besides that, Docker and Docker Compose are well suited for developing and deploying applications on Raspberry Pi since they are open source and can be freely used.
