Docker Volumes and Bind Mounts Explained Simply: Where Container Data Is Stored
In this video, we'll explore how persistent storage works in Docker and what happens to data after a container is deleted. Using practical examples, I'll show the difference between Docker Volumes and Bind mounts, where Docker stores volumes, how to declare a VOLUME in a Dockerfile, how to mount storage using docker run -v, and which commands to use to manage volumes: docker volume ls, docker volume inspect, docker volume rm. This video is perfect for anyone learning Docker, DevOps, and Kubernetes and wanting to properly store logs, application data, and databases in containers.
