Docker Volumes Cheat Sheet

List Volumes

Show all Docker volumes.

docker volume ls

Create Volume

Create a new volume.

docker volume create <volume-name>

Create with driver options:

docker volume create --driver local --opt type=nfs my-volume

Inspect Volume

View detailed volume information.

docker volume inspect <volume-name>

Remove Volume

Delete a volume.

docker volume rm <volume-name>

Remove all unused volumes:

docker volume prune

Mount Volume to Container

Run container with volume mount.

docker run -v <volume-name>:/path/in/container image-name

Example:

docker run -v my-data:/data nginx

Bind Mount

Mount host directory to container.

docker run -v /host/path:/container/path image-name

Read-only bind mount:

docker run -v /host/path:/container/path:ro image-name

Named vs Anonymous Volumes

Named volume:

docker run -v my-volume:/data nginx

Anonymous volume:

docker run -v /data nginx

Mount Volume with --mount

Modern syntax for mounting volumes.

docker run --mount source=my-volume,target=/data nginx

Read-only mount:

docker run --mount source=my-volume,target=/data,readonly nginx

Copy Data to Volume

Backup volume data.

docker run --rm -v my-volume:/source -v $(pwd):/backup ubuntu tar czf /backup/backup.tar.gz -C /source .

Restore Data to Volume

Restore from backup.

docker run --rm -v my-volume:/target -v $(pwd):/backup ubuntu tar xzf /backup/backup.tar.gz -C /target

Share Volume Between Containers

Multiple containers can use same volume.

docker run -v shared-data:/data container1
docker run -v shared-data:/data container2

Volume Drivers

Use third-party storage drivers.

docker volume create --driver local \
  --opt type=nfs \
  --opt o=addr=192.168.1.1,rw \
  --opt device=:/path/to/dir \
  nfs-volume
