Docker Engine Community Server on Ubuntu 22.04

Docker is a platform for developers and sysadmins to build, run, and share applications with containers. The use of containers to deploy applications is called containerization. Containers are not new, but their use for easily deploying applications is.

The Docker CLI uses the Docker REST API to control or interact with the Docker daemon through scripting or direct CLI commands. Many other Docker applications use the underlying API and CLI.

The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A daemon can also communicate with other daemons to manage Docker services.

Dockers portability and lightweight nature also make it easy to dynamically manage workloads, scaling up or tearing down applications and services as business needs dictate, in near real time.

Docker Features

Lightweight containers spin up fast and optimally use system resources
Docker daemon (dockerd) manages Docker objects such as images, containers, networks, and volumes
Docker registry to store Docker images
REST API which specifies interfaces that programs can use to talk to the daemon and instruct it what to do
Command line interface (CLI) client (the docker command)
Namespaces provide a layer of isolation
Control groups to limit applications to a set of resources
Union file systems (UnionFS)
Container format (libcontainer)
Access to Docker hub public images

Docker Support

Docker Engine is supported on a variety of Linux distributions. Docker provides official images for many popular applications and services, making it easy to get started with containerization.
