SPIS

This project is called "Simple Private Image Server" or SPIS for short. It's purpose is to be a lightweight and fast server to display media hosted on a private server. This project came about when I was searching for a solution like this and found nothing. Everything seemed way too feature heavy and slow, requiring you to setup databases and other unnecessary components.

The goals for this project are:

Simple to setup 🏝️
Flexible to operate ➰
Lightweight, multi-threaded and fast 🚀
Minimalistic GUI 🤩
Easy to use on mobile 📱

Some features worth mentioning:

Endless scrolling 📜
Mark favorites ❤️
Filter by year, month, favorites 🎚️
Instantly load new files 📨
Is a progressive web app 📲

I personally use this project to host around 40.000 images on a Raspberry Pi CM4 🤯

If this project is just what you needed and/or has been helpful to you, please consider buying me a coffee ☕

Configuration

Configuration is done either by passing in the appropriate flags or setting environmental variables. You can always run spis help to see how to configure the server:

$ spis help
Simple private image server

Usage: spis [OPTIONS] [COMMAND]

Commands:
  run       Runs the server [default]
  process   Test process media files
  template  Render configuration templates
  help      Print this message or the help of the given subcommand(s)

Options:
      --media-dir <MEDIA_DIR>
          Path to search for media files [env: SPIS_MEDIA_DIR=] [default: ]
      --data-dir <DATA_DIR>
          Path to store data [env: SPIS_DATA_DIR=] [default: ]
      --processing-schedule <PROCESSING_SCHEDULE>
          Schedule to run processing on [env: SPIS_PROCESSING_SCHEDULE=] [default: "0 0 2 * * *"]
      --processing-run-on-start
          Run processing on start [env: SPIS_PROCESSING_RUN_ON_START=]
      --api-media-path <API_MEDIA_PATH>
          Path webserver will serve media on [env: SPIS_API_MEDIA_PATH=] [default: /assets/media]
      --api-thumbnail-path <API_THUMBNAIL_PATH>
          Path webserver will serve thumbnails on [env: SPIS_API_THUMBNAIL_PATH=] [default: /assets/thumbnails]
      --server-address <SERVER_ADDRESS>
          Listen to address [env: SPIS_SERVER_ADDRESS=]

      --feature-follow-symlinks
          Disable feature follow symlinks [env: SPIS_FEATURE_FOLLOW_SYMLINKS=]
      --feature-allow-no-exif

  -h, --help
          Print help
  -V, --version
          Print version

Note

Either SERVER_ADDRESS or SERVER_SOCKET need to be set, but not both!

Tip

Both SPIS_API_MEDIA_PATH and SPIS_API_THUMBNAIL_PATH refer to how the webserver (nginx) is configured to serve media. For a details on how this works, look at the diagram.

Running

Docker

Easiest way to run spis is with the docker image:

$ docker run -it \
    -p 8080:8080 \
    -v /path/to/your/media:/var/lib/spis/media \
    -v /path/to/save/data:/var/lib/spis/data \
    ghcr.io/gbbirkisson/spis

or using docker compose. Try the docker compose example by running...

$ cd examples/docker
$ docker compose up
... and open up http://localhost:8080 in your browser.

Binary

If you want to run the binary, you will need to understand that spis needs a webserver to serve media.

Why do we need a webserver

Because, serving images and videos is complicated! It involves caching, compressing, streaming and a host of other problems that spis does not need to know about. Some people that are way smarter than me have found a solution for all these problems. So instead of implementing a bad solution in spis, we stand on the shoulders of others and use a tried and tested webserver to handle this complexity for us.

Diagram

So how do these things tie together. Well here is a simplified diagram of what happens when you open up spis in the browser.

Note

Never during the interaction does spis read images of the file system and serve them.

sequenceDiagram
    participant U as Browser
    participant W as Webserver
    participant S as SPIS
    participant F as File System
    autonumber
    Note over U: User opens webpage in browser
    U ->> W: GET /
    W ->> S: GET /
    S ->> W: Returns page
    W ->> U: Returns page
    Note over U: Browser fetches thumbnails
    U ->> W: GET <SPIS_API_THUMBNAIL_PATH>/thumb.webp<br/>i.e.<br/>GET /assets/thumbnails/thumb.webp
    W -->> F: Reads <SPIS_DATA_DIR>/thumbnails/thumb.webp<br/>i.e.<br/>Reads /data/thumbnails/thumb.webp
    W ->> U: Returns thumb.webp
    Note over U: Browser fetches video
    U ->> W: GET <SPIS_API_MEDIA_PATH>/video.mp4<br/>i.e.<br/>GET /assets/media/video.mp4
    W -->> F: Reads <SPIS_MEDIA_DIR>/video.mp4<br/>i.e.<br/>Reads /media/video.mp4
    W ->> U: Streams video.mp4

So how do I set this up?

Well these are the steps:

Download a binary for your architecture and put in your path
Install a webserver
For video support make sure ffmpeg and ffprobe are in your path.
Configure spis and run....we will get back to this
Configure webserver and run....we will get back to this

Now, steps 4-5 are super unhelpful (a bit like instructions on how to draw an owl). This is because spis is flexible, and does not care how you do this. You can use any combination of webserver + supervisor to get this up and running. So covering every single way to set this up is not feasible.

So I'm just going to describe how to do this with systemd and nginx on a debian system.

Debian + Systemd + Nginx

Note

We are using configuration templating in this example!

# 1.1 Download spis
$ sudo curl -L -o /usr/local/bin/spis https://github.com/gbbirkisson/spis/releases/download/latest/spis-x86_64-unknown-linux-gnu

# 1.2 Make executable
$ sudo chmod +x /usr/local/bin/spis

# 2. Install nginx
$ sudo apt install nginx

# 3. Add video support
$ sudo apt install ffmpeg

# 4.1 Set SPIS dirs
$ export SPIS_MEDIA_DIR=/storage/spis/media
$ export SPIS_DATA_DIR=/storage/spis/data

# 4.2 Create spis dirs
$ mkdir -p ${SPIS_MEDIA_DIR} ${SPIS_DATA_DIR}

# 4.3 Make sure user `www-data` owns dirs
$ chown www-data:www-data ${SPIS_MEDIA_DIR} ${SPIS_DATA_DIR}

# 4.4 Configure systemd to run spis
$ sudo spis --server-socket ${SPIS_DATA_DIR}/spis.sock \
    template systemd --bin $(which spis) --user www-data > /etc/systemd/system/spis.service

# 4.5 Enable and start spis service
$ systemctl enable --now spis

# 5.1 Configure nginx
$ spis
    --server-socket /storage/spis/data/spis.sock \
    template nginx --port 8080 > /etc/nginx/sites-available/default

# 4.5 Enable and start nginx service
$ systemctl enable --now nginx

Now spis will process and serve any image/video that you place in /storage/spis/media. Just make sure the files are owned by the www-data user.

Open up spis on http://yourserver:8080

Configuration templating

You can use spis to render configuration for various components. In fact, the examples in this repository are all created this way.

$ spis template --help
Render configuration templates

Usage: spis template <COMMAND>

Commands:
  nginx           Template nginx configuration
  systemd         Template systemd configuration
  docker-compose  Template docker compose configuration
  help            Print this message or the help of the given subcommand(s)

Options:
  -h, --help  Print help

Progressive Web App

You can add spis as a PWA to your desktop or mobile. Open up the spis home page in a browser on the device, open the top-right menu, and select Add to Home screen, Install or something to that extent.

Changelog

You can take a look at the CHANGELOG for version information and release notes.

Development

I use direnv to setup the development environment and make to run everything.

Setup toolchain

# Setup rust toolchain
$ make toolchain

# You need nginx installed on your system
$ sudo apt install nginx

Install pre-commit hooks

$ pre-commit install --hook-type commit-msg

Get some test media

I leave it up do you to put some images/videos in the ./data/media folder.

Running

Run stack with:

$ make dev

And then open http://localhost:8080 in your browser
