Alternative to docker kill
- docker stop: The docker stop command is used to stop one or more running containers1. It sends a SIGTERM signal to the main process inside the container, allowing it to shut down gracefully. If the process does not stop after a grace period (10 seconds by default), Docker automatically issues a docker kill command.
- Here’s the basic usage of the command:
docker stop [OPTIONS] CONTAINER [CONTAINER...]
The –signal and –time options allow you to specify a different signal to be sent to the container and the seconds to wait before killing the container, respectively.
docker stop container_name_or_ID
docker stop --time=30 container_name_or_IDdocker stop provides a safe way out and is the preferred method to stop a container as it allows the process to shut down gracefully. If a docker stop command fails to terminate a process within the specified timeout, Docker issues a docker kill command implicitly and immediately.
- Here’s the basic usage of the command:
- docker restart: The docker restart command is used to restart one or more containers.
docker restart container
The docker restart command will issue a stop and then a start. If the container is already stopped, it is functionally the same as docker start
What Is Docker kill ?
Docker is an open platform that helps you build, ship, and run applications anywhere. You can think of it like a shipping container for code; it packages up an application with everything it needs to run (like libraries and system tools) and makes sure it works the same no matter where it’s deployed. Here’s a quick rundown:
- Develop: Write your application code in any language, using any stack.
- Package: Docker containers package up the code and all its dependencies.
- Distribute: Share your container using Docker’s registry, like Docker Hub.
- Run: Deploy your container to any machine that runs Docker, and it will run exactly the same.
- Docker is great for ensuring consistency across multiple development, staging, and production environments. It’s also handy for developers because it runs on various systems, such as Windows, macOS, and Linux.
