I created a docker image which will support preview generation, and viewing of .HEIC and .MOV files (from iOS platforms) and display on all platforms (i.e. Windows too). I’d be very interested in feedback or better ways to accomplish.
Chasing permission errors from the preview generation app, led me to the discovery that if I used imagemagick version 7 and made edits to the “/etc/Imagemagick-6/policy.xml” file, the errors resolved themselves.
The build of imagemagick-7 comes from reference link for Imagemagick-7 build: GitHub - SoftCreatR/imei: IMEI - ImageMagick Easy Install
Dockerfile contents:
FROM nextcloud:fpm COPY install-packages.sh . RUN ./install-packages.sh
install-packages.sh (don’t forget to chmod a+x install-packages.sh)
#!/bin/bash set -euo pipefail export DEBIAN_FRONTEND=noninteractive apt-get update apt-get -y upgrade apt-get -y install git nano -y apt-get -y install software-properties-common -y apt-get -y install ffmpeg -y apt-get -y install exiftool -y # the following will install imagemagick-6 and associated tools apt-get -y install imagemagick imagemagick-common -y # the following lines will overwrite imagemagick with version 7 and install within image git clone https://github.com/SoftCreatR/imei cd imei ./imei.sh # following lines modifiy the policy.xml file to allow PDF cp /etc/ImageMagick-6/policy.xml /etc/ImageMagick-6/policy.xml.bak sed -i "s/rights\=\"none\" pattern\=\"PS\"/rights\=\"read\|write\" pattern\=\"PS\"/" /etc/ImageMagick-6/policy.xml sed -i "s/rights\=\"none\" pattern\=\"EPI\"/rights\=\"read\|write\" pattern\=\"EPI\"/" /etc/ImageMagick-6/policy.xml sed -i "s/rights\=\"none\" pattern\=\"PDF\"/rights\=\"read\|write\" pattern\=\"PDF\"/" /etc/ImageMagick-6/policy.xml sed -i "s/rights\=\"none\" pattern\=\"XPS\"/rights\=\"read\|write\" pattern\=\"XPS\"/" /etc/ImageMagick-6/policy.xml apt-get clean rm -rf /var/lib/apt/lists/*
Then build with
docker build -t nextcloud:fpm .
