1. Is this request related to a challenge you're experiencing? Tell me about your story.

When I was trying to deploy Dify using docker-compose, I wanted to reuse Traefik on my server this time.
Therefore, I hope to have a better understanding of the environment variables related to URLs.
This would help me set the appropriate Traefik labels to route requests to the correct services.

However, I noticed that there are six configurations related to URLs among the environment variables.

CONSOLE_API_URL=
CONSOLE_WEB_URL=
SERVICE_API_URL=
APP_API_URL=
APP_WEB_URL=
FILES_URL=

In the Docker-Compose setup, I understand that only two services, "api" and "web," need to be directly accessible from the outside of the server.

  api:
    image: langgenius/dify-api:0.11.1

  web:
    image: langgenius/dify-web:0.11.1
    restart: always
    environment:
      CONSOLE_API_URL: ${CONSOLE_API_URL:-}
      APP_API_URL: ${APP_API_URL:-}

From this segment of the docker-compose file, I am guessing that：

• "CONSOLE_API_URL" and "APP_API_URL" actually correspond to the "api" Docker service.

I can also only guess that：

• "CONSOLE_WEB_URL," "APP_WEB_URL," and "FILES_URL" might correspond to the "web" Docker service
• and "SERVICE_API_URL" corresponds to the "api" Docker service.

Is my understanding correct?

I'd greatly appreciate it if someone could help clarify the relationship between these environment variables and the corresponding docker services.
Thank you very much!
