About DeployLark

Docker Compose guides and error fixes for self-hosted apps like Vaultwarden, Uptime Kuma, n8n, Paperless-ngx and Open WebUI, tested on real Linux.
Who it is for
Self-hosters and small teams running open-source apps on their own Linux servers
Problem it solves
Docker Compose setups for self-hosted apps often break in ways the official docs do not cover: a reverse proxy that hides WebSocket upgrades, an app that refuses to start because HTTPS is required, or a container that cannot reach another service on the same host. People end up piecing answers together from scattered forum threads instead of following one tested walkthrough.
The solution
Step-by-step tutorials for self-hosted software, open-source projects and developer tools. Every command in a tutorial is run on a real Linux machine before it is published, and the output shown is what that machine actually printed.
What makes it unique
Every guide is written against a real Linux server rather than a lab mock-up: it starts at docker compose up and ends at the reverse proxy, HTTPS and updates, and it names the specific errors people actually hit instead of only showing the happy path.

Features

  • Docker Compose walkthroughs
