What are Docker Volumes?
Docker Volumes are a popular and effective method for assuring data permanence while working in containers. Docker volumes are file systems that are mounted on Docker containers to preserve the data generated by the container.
What Is Docker Volume?
Docker containers enable apps to execute in an isolated environment. All modifications made inside the container are lost by default when it ends. Docker volumes and bind mounts can be useful for storing data in between runs. One way to store data outside of containers is with volumes. All volumes are kept in a specific directory on your host, typically /var/lib/docker/volumes for Linux systems, and are controlled by Docker.
