What is a Docker container?
|
|
Docker is a platform as a service product (PaaS) that uses OS-level virtualization and delivers encapsulated software in packages called containers. The software that hosts the container is called Docker Engine. Libraries, packages, and services isolate the containers from one another, but they can easily communicate over defined channels.

A Docker container is a standard software unit with packaged code and all its dependencies for the application to run smoothly in its environment isolated from another. We need the Docker image to create the Docker container. The Docker Container image is a read-only template with instructions for creating a Docker container. It is a lightweight standalone executable package that contains everything the application needs to run, such as code, system libraries, system tools, settings, etc. The containerized software will always run the same whether using Windows or Linux. Docker allows us to build, test, and deploy our applications quickly. The containers are lightweight, standard, and secure. Full Story |
