How to assign subdomain to docker compose application?

Im playing around with compose feature, following docs from here https://docs.dokploy.com/en/docker-compose/example For me it seems that traefic labels do nothing. I was trying to deploy https://github.com/Dokploy/docker-compose-test/blob/main/docker-compose.yml example app but it traefic service and configuration is not affected. I also see cryptic errors in docker logs for dokploy like

Error Error: child exited with code 18

    at ChildProcess.emit (node:events:517:28)

Not sure if its related... Currently Im editing traefic config files in dynamic/ myself to assign hosts, not ideal. Would be great to have a way to assign a subdomain to a port in a nice way

share your main traefik config 1. the docker compose build were succesfully? 2. the application is running and do you see any logs?

Siumauricio•11mo ago

if you had dokploy installed before version v0.2.0, you have to make these changes manually to be able to use docker compose with traefik https://github.com/Dokploy/dokploy/releases/tag/v0.2.0

Can you share docker compose configuration

KirillOP•11mo ago

Sorry, @𝗠𝗿𝟭𝗕𝗹𝗮𝘇𝗲 , do you mean docker-compose.yml file? It is this one https://github.com/Dokploy/docker-compose-test/blob/main/docker-compose.yml

Here is build log from

message.txt

Siumauricio•11mo ago

have you check this?

KirillOP•11mo ago

No, I just reinstalled dokploy to have fresh install so its 0.2.2 version

Siumauricio•11mo ago

did you modify the labels of the docker compose?

KirillOP•11mo ago

No, used as is

KirillOP•11mo ago

Siumauricio•11mo ago

Follow the example, if you had any questions let me know!: https://docs.dokploy.com/en/docker-compose/example#tutorial

I think example is a bit misleading: - your-domain.com and next-app on the screenshot from cloudflare panel are different values - even if you have example in github you cant use it as is to because host is hardcoded - you actually need to fork repo, edit it, commit, and then use it in dokploy I think there is no way traefik.http.routers.<unique-name>.rule value might be configurable from ui? as its parsed before docker build

Siumauricio•11mo ago

It is clear, you will not use the same domain of your-domain.com and use next-app as an example that I put in the cloudflare, and it is clear that you can not use the same example that's why it mentions that you make a fork, and there is a section that mentions you need to modify the existing docker compose file, We could do something similar, however we prefer to keep the docker compose standard and not alter its behavior internally, so you have full control of your file.

Finally I managed to make this labels for trafic actualy work. For this I had to reinstall docker as previous installation of dokploy somehow affected Here, I created simplier compose example that you may use in docs

version: "3"
 
services:
  todo-list:
    image: thoba/todo-list-app
    restart: always
    ports:
      - 8080
    networks:
      - dokploy-network
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.todo-list-example.rule=Host(`YOUR_DOMAIN`)"
      - "traefik.http.routers.todo-list-example.entrypoints=websecure"
      - "traefik.http.routers.todo-list-example.tls.certResolver=letsencrypt"
      - "traefik.http.services.todo-list-example.loadbalancer.server.port=8080"
networks:
  dokploy-network:
    external: true

version: "3"
 
services:
  todo-list:
    image: thoba/todo-list-app
    restart: always
    ports:
      - 8080
    networks:
      - dokploy-network
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.todo-list-example.rule=Host(`YOUR_DOMAIN`)"
      - "traefik.http.routers.todo-list-example.entrypoints=websecure"
      - "traefik.http.routers.todo-list-example.tls.certResolver=letsencrypt"
      - "traefik.http.services.todo-list-example.loadbalancer.server.port=8080"
networks:
  dokploy-network:
    external: true

Managed to make it work on my machine https://todo.dokploy.kcrz.dev/ Guess, this question is no longer relevant, as this issue was caused (most likely) by my previous dokploy install. So if something works buggy — reinstall docker
