# Immich Photo Import Script — generated by ubuntu-post-install
#
# Imports your existing photo collection into Immich with EXIF date preservation.
# Photos are uploaded through the API so Immich extracts metadata (dates, GPS,
# camera info) from the originals.
#
# What this script does:
#   1. Creates admin account (if first run) or logs in
#   2. Generates an API key automatically
#   3. Configures the storage template (date-based organization)
#   4. Installs the Immich CLI (if needed)
#   5. Uploads all photos with EXIF metadata preserved
#
# Usage:
#   ./import-photos.sh              # interactive (prompts for everything)
#   ./import-photos.sh <api-key>    # skip account setup, use existing key

# Immich

Self-hosted photo and video backup — like Google Photos but private.
Mobile apps (iOS/Android) auto-upload in the background.

- Web UI: http://localhost:2283
- Photo storage: \`$UPLOAD_LOCATION\`
- App data (postgres, model cache): inside this folder
- Edit paths in \`.env\`, then \`docker compose up -d\` to apply.

## Manage
\`\`\`bash
cd $IMMICH_DIR
docker compose up -d      # start all containers
docker compose down       # stop
docker compose logs -f    # logs
docker compose pull && docker compose up -d   # update
\`\`\`

## First launch
1. Open http://localhost:2283 and create your admin account.
2. Install the Immich mobile app and point it at \`http://<server-ip>:2283\`.
3. (External library mode) Go to Admin → External Libraries → Create Library,
   set import path to \`/usr/src/app/external\`, and click Scan.

## Import existing photos (unified mode)
\`\`\`bash
./import-photos.sh          # interactive
./import-photos.sh <key>    # skip login, use existing API key
\`\`\`

## Notes
- Machine learning features (face recognition, CLIP search) require the
  \`immich-machine-learning\` container — it pulls a large model on first run.
- The \`.immich\` marker files in the upload subdirs are required by Immich;
  do not delete them.
