Running Vikunja with Docker and Tailscale

Hi there !

I’m trying to run my first instance of Vikunja and I’m using taiscale for all my other services.
When I try to access to the app, nothing …
Actually, I’ve this docker-compose.yml :

services:
  vikunja:
    image: vikunja/vikunja
    container_name: vikunja
    environment:
      VIKUNJA_SERVICE_PUBLICURL: http://localhost
      VIKUNJA_DATABASE_HOST: db
      VIKUNJA_DATABASE_PASSWORD: ${DBPWD}
      VIKUNJA_DATABASE_TYPE: mysql
      VIKUNJA_DATABASE_USER: ${DBUSER}
      VIKUNJA_DATABASE_DATABASE: ${DBNAME}
      VIKUNJA_SERVICE_JWTSECRET: ${VIKUNJASECRET}

    volumes:
      - vl_vikunja:/app/vikunja/files
    depends_on:
      db:
        condition: service_healthy
    restart: unless-stopped
    network_mode: service:ts_vikunja

  db:
    image: mariadb:10
    container_name: vikunja_db
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    environment:
      MYSQL_ROOT_PASSWORD: ${DBROOT}
      MYSQL_USER: ${DBUSER}
      MYSQL_PASSWORD: ${DBPWD}
      MYSQL_DATABASE: ${DBNAME}
    volumes:
      - vl_vikunja_db:/var/lib/mysql
    restart: unless-stopped
    healthcheck:
      test: ["CMD-SHELL", "mysqladmin ping -h localhost -u $$MYSQL_USER --password=$$MYSQL_PASSWORD"]
      interval: 2s
      start_period: 30s
    networks:
      - nt_prod

  ts_vikunja:
    image: tailscale/tailscale:latest
    container_name: ts_vikunja
    hostname: vikunja
    environment:
      - TS_ACCEPT_DNS=true
      - TS_AUTHKEY=${TS}
      - TS_STATE_DIR=/var/lib/tailscale
      - TS_SERVE_CONFIG=/config/${TSFILE}
      - TS_SOCKS5_SERVER=localhost:1055
    volumes:
      - vl_ts_vikunja:/var/lib/tailscale
      - /dev/net/tun:/dev/net/tun
      - ${TSCONFIG}/config_ts:/config
    cap_add:
      - net_admin
      - sys_module
    networks:
      - nt_prod

networks:
  nt_prod:
    external: true

volumes:
  vl_vikunja:
    external: true
  vl_vikunja_db:
    external: true
  vl_ts_vikunja:
    external: true

All logs looks OK :

I tryied already multiple things with the “VIKUNJA_SERVICE_PUBLICURL:”

This is not working from localhost too…

If someone have an idea… :grimacing:

I don’t know anything about how tailscale does things here, but does it work when you add the port? https://vikunja.mytailscaledomain.ts.net:3456 or similar. (how does Tailscale know which port to forward?)

This line in the logs seems to indicate it will forward traffic to port 3456 on the tailscale container which won’t work - it needs to forward traffic to the Vikunja container.
