Yes, there is experience with managing data volumes in Docker. Volumes are used for persistent storage of data outside the container, so data is not lost when the container is recreated.
Main points:
- Volumes are created and managed by Docker, stored in a special area on the host.
- You can mount a volume into a container using the
-vor--mountoption. - Volumes allow sharing data between containers.
- For backup and data migration, you can use the
docker volumecommands.
Example of creating and using a volume:
docker volume create mydata
docker run -d -v mydata:/app/data myimage
Here, the volume mydata is created and mounted into the container at /app/data.
You can also use bind mounts if you need to mount a specific folder from the host.
