It can also test, ship, and deploy code quickly, which helps minimize the delay between writing code and executing it in an environment. Docker is suitable for developers who require a lightweight, small, and clean environment for testing purposes and wish to avoid extensive management and configurations. One of the best things about using an open-source project is the freedom to choose the technology you want to utilize to complete any task. Any changes to a container’s state that are not saved in persistent storage are lost when the container is removed.

The image of a container and any configuration parameters you provide is used for building or starting it. You have control over the isolated network of a container, its storage, and other underlying subsystems. It also provides you the facility to connect a container to one or more networks, attach any storage it, or create a new Docker image out of an existing state.Ī container is often well separated from its host and default machine. With the use of Docker API or CLI, you can perform different operations in a Docker container. Docker Containerĭocker Containers can be thought of as executable images. The Docker project made it easier for developers to package their application as a “ build once and run anywhere” strategy. At that time, the containers were already used in Linux-based systems.

These containers are the lightweight and small execution environments that share the operating system kernel however, they operate in isolation. Docker is a framework that is utilized for developing container-based applications.
