Tips & Tricks

Generate password/secret key

openssl rand -base64 32

Enable HEIC & MOV previews

  1. Make sure that Preview Generator app is installed
  2. Add this section to the config.php
  'enable_previews' => true,
  'enabledPreviewProviders' => [
    'OC\Preview\PNG',
    'OC\Preview\JPEG',
    'OC\Preview\GIF',
    'OC\Preview\HEIC',
    'OC\Preview\BMP',
    'OC\Preview\XBitmap',
    'OC\Preview\MP3',
    'OC\Preview\TXT',
    'OC\Preview\MarkDown',
    'OC\Preview\OpenDocument',
    'OC\Preview\Krita',
    'OC\Preview\Movie',
    'OC\Preview\MKV',
    'OC\Preview\MP4',
    'OC\Preview\AVI',
    'OC\Preview\MSOffice2003',
    'OC\Preview\MSOffice2007',
    'OC\Preview\MSOfficeDoc',
    'OC\Preview\PDF',
    'OC\Preview\SVG',
  ],
  1. If you don't see the previews, try running this command:
docker-compose exec -u www-data app bash -c ."/occ preview:generate-all -vvv"
  1. For video previews you need to install ffmpeg, like so:
docker-compose exec app bash -c "apt update && apt upgrade -y && apt install -y ffmpeg"
# optionally add imagemagick and ghostscript
  1. This will not persist so it must be run every time the container restarts...
  2. Alternative is to manually build docker image :-|

Bookmarks previews

For bookmarks previews it's required to have a screenshotting service. Screenly can be easily self-hosted.
