Komga in Docker Swarm
Get your FREE "elfhosted" Komga instance for demo / trial
Want to see a live demo, or "kick the tyres" before you commit to self-hosting Komga?
So you've just watched a bunch of superhero movies, and you're suddenly inspired to deep-dive into the weird world of comic books? You're already rocking AutoPirate with Mylar and NZBGet to grab content, but how to manage and enjoy your growing collection?
Komga is a media server with a beautifully slick interface, allowing you to read your comics / manga in CBZ, CBR, PDF and epub format. Komga includes an integrated web reader, as well as a Tachiyomi plugin and an OPDS server for integration with other mobile apps such as Chunky on iPad.
- 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
Setup data locations
First we create a directory to hold the komga database, logs and other persistent data:
Komga Docker Swarm config
Create a docker swarm config file in docker-compose syntax (v3), something like the example below:
Fast-track with premix! 🚀
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)
version: "3.2" services: komga: image: gotson/komga env_file: /var/data/config/komga/komga.env volumes: - /var/data/media/:/media - /var/data/komga:/config deploy: replicas: 1 labels: # traefik common - traefik.enable=true - traefik.docker.network=traefik_public # traefikv1 - traefik.frontend.rule=Host:komga.example.com - traefik.port=8080 # traefikv2 - "traefik.http.routers.komga.rule=Host(`komga.example.com`)" - "traefik.http.services.komga.loadbalancer.server.port=8080" - "traefik.enable=true" # Remove if you wish to access the URL directly - "traefik.http.routers.komga.middlewares=forward-auth@file" networks: - traefik_public networks: traefik_public: external: true
Launch the Komga stack by running
docker stack deploy komga -c <path -to-docker-compose.yml>
Log into your new instance at https://YOUR-FQDN. Since it's a fresh installation, Komga will prompt you to setup a username and password, after which you'll be able to setup your library, and tweak all teh butt0ns!
Save teh wurld!
If Komga scratches your particular itch, please join me in sponsoring the developer
Chef's notes 📓
Since Komga doesn't need to communicate with any other services, we don't need a separate overlay network for it. Provided Traefik can reach Komga via the
traefik_publicoverlay network, we've got all we need. ↩
