Streamlit webapp and https-portal configuration issues - docker-compose

Question

I have a Streamlit webapp on my test pc that I deployed with docker. The app is accessible online only on http. I wanted to use https so I found this docker image :https://hub.docker.com/r/steveltn/https-portal
It seems an easy way to enable https, but I didn't have any success.
Here is my docker-compose.yaml:
services:
https-portal:
image: steveltn/https-portal:1
ports:
- '80:80'
- '443:443'
links:
- streamlit_app
restart: always
environment:
WEBSOCKET: 'true'
DOMAINS: 'http://example.go.ro/ -> http://streamlit_app:8501'
STAGE: production # mantenha em staging até o total funcionamento
volumes:
- https-portal-data:/var/lib/https-portal
streamlit_app:
build:
dockerfile: ./Dockerfile
context: ./
volumes:
- .:/ETCWebApp
ports:
- 8501:8501
restart: always
Using this config, I still only get http not https.
Update:
This is the error I am getting:
Failed to sign example.go.ro.
https-portal_1 | Make sure your DNS is configured correctly and is propagated to this host
https-portal_1 | machine. Sometimes that takes a while.

Answer 1

It works with the folowing config:
services:
streamlit_app:
build:
dockerfile: ./Dockerfile
context: ./
volumes:
- .:/ETCWebApp
ports:
- 8501:8501
restart: unless-stopped
https-portal:
image: steveltn/https-portal:1.22
depends_on:
- streamlit_app
ports:
- '80:80'
- '443:443'
restart: unless-stopped
environment:
WEBSOCKET: 'true'
DOMAINS: 'example.go.ro -> streamlit_app:8501'
Also port forwarding between router and pc (80:80, 443:443)
