Avoiding Docker Kill for production environment
- Using docker kill in a production environment should be avoided whenever possible, as it can lead to data loss and does not allow the process to shut down gracefully-
- Here are some considerations:
- Graceful Shutdown – Always try to stop containers gracefully using docker stop before resorting to docker kill.
- Resource Limits – Set resource limits to prevent a single container from consuming all the system resources and becoming unresponsive.
- Use Small-Sized Official Images: Using smaller images means you need less storage space in the image repository as well as on a deployment server, and you can transfer the images faster when pulling or pushing them from the repository.
- Security: Define and enforce custom policies to limit the number of privileges assigned to each one of the containers in your infrastructure.
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.
