This script extracts a dataset from a versioned Docker image in a container registry and restores it to a local directory.

unpackage_dataset_image.sh

# Replace <DATASET_NAME> with the name of your dataset
DATASET="<DATASET_NAME>"

# Replace <SUBDIR> with the name of your local data subdirectory
SUBDIR="<LOCAL_DATA_SUBDIRECTORY>"

# Ensure output directory exists
mkdir --parents "data/${SUBDIR}"

# Create a temporary container from the image
docker create --name "${DATASET}_data_extract" "islasgeci/${DATASET}_data:latest"

# Copy data from container to host
docker cp "${DATASET}_data_extract":/data/. "data/${SUBDIR}"

# Remove temporary container
docker rm --force "${DATASET}_data_extract"
