Docker

Docker, written in Go, is an open platform to build, ship, and run distributed applications. It was first released in 2013 and is developed by Docker, Inc.

Docker is used to run packages called "containers". Containers are isolated from each other and from the OS (Operating System). These are more lightweight than virtual machines as they do not use the host machine to run an operating system.

Containerization, which is a way of deploying and running applications, runs isolated services which run natively on the Linux kernel. Memory can be set manually for each container in Docker.

Docker is used to simplify configurations while ensuring a smooth continuous integration and deployment flow. Specific containers can be specified for development, staging, and production environments. A true implementation of a container in production, according to the Docker manual, is to run it as a service, using the docker-compose.yml file for setup. This is a YAML file that defines how Docker containers should behave in production.

One of Docker's biggest advantages is that it can be used by a team using different operating systems to build projects without needing to worry about software conflicts.
