Description: The ‘docker stop’ command is a fundamental tool in managing containerized applications using Docker, used to stop running containers in a controlled manner. This command sends a SIGTERM signal to the main process of the container, allowing it to shut down gracefully. If the container does not stop within a specified time, a SIGKILL signal is sent to force its termination. This functionality is crucial to ensure that processes within the container have the opportunity to release resources and complete pending tasks before being terminated. ‘docker stop’ is part of a broader set of commands that enable developers and system administrators to manage containers efficiently, facilitating orchestration and maintenance of applications in various environments. Its use is common in situations where a service needs to be temporarily stopped, updates need to be performed, or system resources need to be freed. In summary, ‘docker stop’ is an essential tool for container management, ensuring that processes are closed safely and orderly.
History: Docker was released in March 2013 by Solomon Hykes as an open-source project. Since its inception, the Docker ecosystem has rapidly evolved, becoming one of the most popular tools for creating and managing containers. The ‘docker stop’ command was introduced as part of this suite of tools from the beginning, allowing users to efficiently manage the lifecycle of containers.
Uses: The ‘docker stop’ command is primarily used to stop running containers in a controlled manner. This is useful in situations where maintenance, updates, or system resource release is needed. It is also used in automation scripts and orchestration environments to manage the lifecycle of services in containers.
Examples: A practical example of using ‘docker stop’ would be in a development environment where a developer needs to stop a container of a web application to apply code changes. The command ‘docker stop
