Types of Docker Data Storage
What are Docker data storage types?
✍: FYIcenter.com
There are 3 main data storage types supported by Docker: tmpfs mounts,
volume mounts, and bind mounts.
1. tmpfs mounts - tmpfs mounts are stored in the host system’s memory only, and are never written to the host system’s filesystem.
2. volume mounts - Volumes are stored in a part of the host filesystem which is managed by Docker (/var/lib/docker/volumes/ on Linux). Non-Docker processes should not modify this part of the filesystem. Volumes are the best way to persist data in Docker.
3. bind mounts - Bind mounts may be stored anywhere on the host system. They may even be important system files or directories. Non-Docker processes on the Docker host or a Docker container can modify them at any time.
Docker data storage can only be mounted when you creating a new container from a Docker image.
Once a container is created, there is no way to mount additional storages.
