Data persistence is a crucial aspect of managing stateful applications in Docker. This lesson is dedicated to understanding and using Docker volumes, an essential tool for persistent data management.
Docker volumes are the preferred mechanism for persisting data generated by and used by Docker containers.
/var/lib/docker/volumes/
Effective use of Docker volumes is key to managing data in containers.
docker volume create [volume-name]
docker volume ls
docker volume inspect [volume-name]
docker volume rm [volume-name]
-v
--mount
docker run -d -v myvol2:/app nginx:latest
Managing and securing data is critical in Docker environments.
By understanding Docker volumes and their application in data persistence, you can effectively manage stateful applications in Docker. This includes not only storing data but also ensuring its availability, security, and integrity over time.
