Am using following nginx conf file :

server {
    listen 80;
    server_name domain;

    # Redirect HTTP to HTTPS
    return 301 https://$host$request_uri;
}
server {
    listen 443 ssl;
    server_name localhost;

    ssl_certificate /etc/nginx/cert/ddomain.crt;
    ssl_certificate_key /etc/nginx/cert/domain.key;

    location / {
        proxy_pass http://0.0.0.0:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

I am using the following docker file to run the container. This container runs 8000 port.

FROM python:3.8

# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# Set the working directory in the container
WORKDIR /app

# Install system dependencies
RUN apt-get update && apt-get install -y 
    gcc 
    gettext 
    dbus 
    libdbus-1-dev 
    libcups2-dev 
    libcairo2-dev 
    libgirepository1.0-dev 
    libgtk-3-dev 
    libsecret-1-dev 
    pkg-config 
    wget 
    nginx 
    && rm -rf /var/lib/apt/lists/*

# Copy the requirements file and install Python dependencies
COPY requirements.txt /app/
RUN pip install --no-cache-dir -r requirements.txt

# Copy SSL certificate files
COPY ssl_certificates/domain.crt /etc/nginx/cert/domain.crt
COPY ssl_certificates/domain.key /etc/nginx/cert/domain.key

# Copy the Nginx configuration file
COPY nginx.conf /etc/nginx/conf.d/default.conf

# Copy the rest of the application files
COPY . /app/

# Expose port 8000 to allow communication to/from server
EXPOSE 8000

# Your application's command to run
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

When accessing the application using https://example.com:8080/. (8080 port is pointed server 8000 port) browser showing :

An error message like: “This site can’t provide a secure connection”

When am checking docker logs: “You’re accessing the development server over HTTPS, but it only supports HTTP.”

How can I enable HTTPS to my domain using a docker file and nginx?

Please help
