Docker is an operating-system-level virtualization and is used to run software packages called containers. Containers are created from images that specify their precise contents. Images are often created by combining and modifying standard images downloaded from public repositories.


All containers are run by a single operating system kernel and are thus more lightweight than virtual machines.

Frequently Asked Questions

What are the system requirements for deploying Docker?

The Linux system requirements for deploying Docker are as follows. For Mac and Windows requirements, see the Docker documentation

64-bit kernel and CPU support for virtualization.
KVM virtualization support. Follow the KVM virtualization support instructions to check if the KVM kernel modules are enabled and how to provide access to the KVM device.
QEMU must be version 5.2 or later. We recommend upgrading to the latest version.
systemd init system.
Gnome, KDE, or MATE Desktop environment.
For many Linux distros, the Gnome environment does not support tray icons. To add support for tray icons, you need to install a Gnome extension. 
At least 4 GB of RAM.
Enable configuring ID mapping in user namespaces.
Recommended: Initialize pass for credentials management.

What are the common use cases for Docker?

Developing and testing applications
Deploying microservices
Running legacy applications
Creating continuous integration and continuous delivery (CI/CD) pipelines
Managing workloads in the cloud
Create sandboxed environments for running untrusted code

What are popular alternatives to Docker?

Docker is a widely used platform for containerization, but there are several alternatives:

Podman, Buildah, Rkt (pronounced “rocket”), LXD (Linux Containers Daemon), Containerd, CRI-O (Container Runtime Interface for OpenShift), and Singularity. 

What query language does Docker use?

Docker does not use a query language in the traditional sense. Docker provides a command-line interface (CLI) that allows users to interact with the Docker Engine, the core component responsible for building, running, and managing containers. Instead of a query language, Docker commands are used to perform various actions and queries related to containerized applications.

Here are some common Docker commands:
docker run: Used to run a command in a new container.
docker ps: Lists the running containers.
docker images: Lists the available images on the local machine.
docker build: Builds a Docker image from a Dockerfile.
docker exec: Runs a command in a running container.
Docker-compose: Manages multi-container applications using a YAML file to define services, networks, and volumes.
