Getting started¶

Docker installation¶

Diskover requires an Elasticsearch instance. Using Docker Compose is the recommended way to set up both:

version: '2'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.10.1
    environment:
      - discovery.type=single-node
  diskover:
    image: lscr.io/linuxserver/diskover
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - ES_HOST=elasticsearch
    volumes:
      - /path/to/config:/config
      - /path/to/data:/data
    ports:
      - 80:80
    depends_on:
      - elasticsearch

CLI examples¶

You can run indexing tasks manually using the diskover.py script inside the container.

# Run a manual index of the /data directory
docker exec -it diskover python3 /app/diskover/diskover.py -i my_index_name /data

# List all current indices in Elasticsearch
curl -X GET "http://localhost:9200/_cat/indices?v"

# Remove an old index
curl -X DELETE "http://localhost:9200/my_old_index"

API examples¶

Diskover stores its data in Elasticsearch, so you can use the Elasticsearch REST API to query Diskover's data.

# Search for files larger than 1GB in the diskover index
curl -X GET "http://localhost:9200/diskover-test/_search?q=filesize:>1073741824&pretty"

Backlog¶

Integrate with TrueNAS SCALE via NFS mount.
