Ever wanted to quickly share a screenshot, but don't want to use imgur, sign up for a service, or have your image tracked across the internet for all time?
Want to privately share some log output with a password, or a self-destructing cat picture?
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
- 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 to secure your Traefik-exposed services with an additional layer of authentication
Setup data locations¶
First we create a directory to hold the data which linx will serve:
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
Setup Docker Swarm¶
Create a docker swarm config file in docker-compose syntax (v3), something like this:
I automatically and instantly share (with my sponsors) a private "premix" git repository, which includes necessary docker-compose and env files for all published recipes. This means that sponsors can launch any recipe with just a
git pull and a
docker stack deploy 👍.
🚀 Update: Premix now includes an ansible playbook, so that sponsors can deploy an entire stack + recipes, with a single ansible command! (more here)

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