dsimaging-admin 0.3.4

Admin CLI for managing medical imaging datasets in S3/MinIO for DataSHIELD

dsimaging-admin

Admin CLI for creating and operating dsimaging-store deployments and the medical imaging datasets stored in them.

Install

pip install dsimaging-admin

Create a store

dsimaging-admin store init writes a Docker Compose project for MinIO plus the dsimaging-store controller.

dsimaging-admin store init ./study-store \
  --controller-image davidsarratgonzalez/dsimaging-store:latest
dsimaging-admin store up ./study-store
dsimaging-admin store doctor ./study-store

For local controller development, build from a checked-out dsimaging-store repo instead of using an image:

dsimaging-admin store init ./study-store \
  --store-source /path/to/dsimaging-store
dsimaging-admin store up ./study-store

Use the generated connection details as a reusable CLI profile:

dsimaging-admin init \
  --endpoint http://127.0.0.1:9000 \
  --controller-url http://127.0.0.1:8080 \
  --bucket imaging-data

Dataset operations

# Publish with staging, publish lock, skip-if-hash-matches and DICOM checks.
dsimaging-admin publish \
  --dataset-id study_ct_v1 \
  --source /data/study_ct \
  --metadata /data/study_ct/clinical.csv \
  --modality ct

# Inspect and verify.
dsimaging-admin list
dsimaging-admin status study_ct_v1
dsimaging-admin verify study_ct_v1
dsimaging-admin doctor

# Rebuild artifacts from S3, copy, download or delete.
dsimaging-admin rescan study_ct_v1
dsimaging-admin copy study_ct_v1 study_ct_v2 --yes
dsimaging-admin download study_ct_v1 ./debug/study_ct_v1
dsimaging-admin delete study_ct_v1 --yes --purge-versions

All reporting commands that are useful for automation support JSON output:

dsimaging-admin list --output json
dsimaging-admin status study_ct_v1 --output json
dsimaging-admin verify study_ct_v1 --output json
dsimaging-admin doctor --output json

What publish does

1. Scans your local image directory and optional masks under source/masks/, masks/, source/labels/, or labels/.
2. Runs basic DICOM sanity checks for series UID, modality and instance order.
3. Computes SHA-256 content hashes.
4. Skips uploads that already match the current dataset hash indexes.
5. Uploads through datasets/<id>/.staging-* and a .publish-lock, then copies into datasets/<id>/source/....
6. Generates and uploads:
   • manifest.yaml
   • indexes/content_hash_index.parquet
   • indexes/masks_content_hash_index.parquet when masks exist
   • metadata/sample_manifests.parquet
   • metadata/samples.parquet

Use --dry-run to scan and show the upload plan without S3 writes, --no-skip to force uploads, or --no-atomic to disable staging.

Configuration

~/.dsimaging.yaml supports multiple profiles:

default_profile: default
profiles:
  default:
    endpoint: http://127.0.0.1:9000
    controller_url: http://127.0.0.1:8080
    bucket: imaging-data
    access_key: minioadmin
    secret_key: minioadmin123
    region: ""

Environment variables override profile values:

Variable	Default	Description
DSIMAGING_PROFILE	default	Config profile
DSIMAGING_ENDPOINT	http://127.0.0.1:9000	S3/MinIO endpoint
DSIMAGING_CONTROLLER_URL	(empty)	dsimaging-store controller URL
DSIMAGING_ACCESS_KEY	minioadmin	S3 access key
DSIMAGING_SECRET_KEY	minioadmin123	S3 secret key
DSIMAGING_BUCKET	imaging-data	Bucket name
DSIMAGING_REGION	(empty)	S3 region

Dataset layout in S3

Store creation and dataset management only target dsimaging-store deployments.
