====== Damselfly ======

**Note:** since i don't use this service anymore, this page might be not updated.

[[https://damselfly.info|Damselfly]] is a digital asset management tool to manage huge collections of photos. Still testing, i love the concept.


===== Installation =====

Installing Damselfly can be done on bare-metal, but the dev does not support it, so i will show you both ways.

In general you can find more installation information [[https://github.com/Webreaper/Damselfly/blob/master/docs/Installation.md|here]].

==== Common installation steps ====

Create a damselfly user and make it member of the //photos// group:
<code bash>
groupadd photos
useradd -d /data/daemons/damselfly -m -g photos damselfly
</code>

Since Damselfly uses INotify triggers, you need to increase defaults or it will be unable to monitor large collections of photos (see [[https://github.com/Webreaper/Damselfly/blob/master/docs/Installation.md#filewatcher-inotify-limits|here]]). 

Create the file **/etc/sysctl.d/damselfly.conf**:
<file damselfy.conf>
fs.inotify.max_user_instances=524288
</file>

And for it to be applied without a reboot:
<code bash>
 sysctl -p /etc/sysctl.d/damselfly.conf
</code>


==== Bare Metal Installation (not recomended) ====

Non-containerized install instructions [[https://github.com/Webreaper/Damselfly/blob/master/docs/Installation.md#can-i-run-damselfly-without-docker|here]]

Download and decompress the release:
<code bash>
su - damselfly
wget https://github.com/Webreaper/Damselfly/releases/download/4.1.0/damselfly-server-linux-4.1.0.zip
mkdir damselfly
cd damselfly
unzip damselfly-server-linux-4.1.0.zip
</code>
(the release zip file requires a sub-folder to store neatly all files)

In order for Damselfly to work you need to install some dependencies, which can be found in the [[https://github.com/Webreaper/Damselfly-Base-Image/blob/main/Dockerfile|Docker file]].

There you go:
<code bash>
emerge -s media-fonts/liberation-fonts dev-dotnet/libgdiplus media-gfx/dcraw media-libs/exiftool
</code>

The supposed //libgmp1// dependency is satisfied by adding **openmp** useflag to GCC (see [[https://forums.gentoo.org/viewtopic-p-5039135.html#6577903|here]]) which should be enabled by default in Gentoo.


==== Podman installation ====

Create the following //docker-compose.yml//:
<file - docker-compose.yml>
version: "3.8"

name: damselfly
    
services:
  damselfly: 
    container_name: damselfly
    image: webreaper/damselfly
    ports:
      - 6363:6363/tcp
    volumes:
      - /data/daemons/damselfly/config:/config
      - /data/daemons/damselfly/thumbs:/thumbs
      - /data/Photos:/pictures 
    restart: unless-stopped

networks:
  damselfly-net: {}
</file>

And install it:
<code bash>
su - damselfly
podman compose pull
</code>


===== Reverse Proxy  =====

Damselfly do not support sub-paths, so you __must__ spin your own subdomain for it to work. Here is the relevant NGINX configuration file:
<file - damselfly.conf>
TBD
</file>


===== Startup =====


==== Bare Metal running  ====

Start:
<code bash>
./Damselfly.Web /path/to/my/photos
</code>

You will need the usual script & /etc/local.d/damselfly.start script for automatic start on boot.

==== Podman running  ====

Running is, as usual:
<code bash>
su - damselfly
podman compose up
</code>

To run at boot, add the following lines to your **/etc/local.d/80-containers.start**:
<code>
podman network create damselfly-net
su - damselfly -c "podman compose up -d"
</code>

and the following lines to  **/etc/local.d/80-containers.stop**:
<code>
su - damselfly -c "podman compose down"
</code>
