Recipe Name on Docker Swarm

Screenshot of Recipe Name

Linx is self-hosted file/media-sharing service, which features:

Display common filetypes (image, video, audio, markdown, pdf)
Display syntax-highlighted code with in-place editing
Documented API with keys for restricting uploads
Torrent download of files using web seeding
File expiry, deletion key, file access key, and random filename options

Recipe Name Requirements

Ingredients

Already deployed:

Docker swarm cluster with persistent shared storage
Traefik configured per design
DNS entry for the hostname you intend to use (or a wildcard), pointed to your keepalived IP

Traefik Forward Auth or Authelia to secure your Traefik-exposed services with an additional layer of authentication

Preparation

Setup data locations

First we create a directory to hold the data which linx will serve:

mkdir /var/data/linx

Create config file

Linx is configured using a flat text file, so create this on the Docker host, and then we'll mount it (read-only) into the container, below.

mkdir /var/data/config/linx
cat << EOF > /var/data/config/linx/linx.conf
# Refer to https://github.com/andreimarcu/linx-server for details
cleanup-every-minutes = 5
EOF

Recipe Name Docker Swarm config

Create a docker swarm config file in docker-compose syntax (v3), something like the example below:

Fast-track with premix! 🚀

"Premix" is a git repository which includes necessary docker-compose and env files for all published recipes. This means that you can launch any recipe with just a git pull and a docker stack deploy 👍.

🚀 Update: Premix now includes an ansible playbook, enabling you to deploy an entire stack + recipes, with a single ansible command! (more here)

Serving

Launch the Linx!

Launch the Linx stack by running docker stack deploy linx -c <path -to-docker-compose.yml>

Chef's notes 📓

Since the whole purpose of media/file sharing is to share stuff with strangers, this recipe doesn't take into account any sort of authentication using Traefik Forward Auth. ↩
