Running an Nginx Docker container with a self-signed SSL certificate involves a few steps. Here’s a step-by-step guide to help you set it up:

1. Create a Self-Signed SSL Certificate:

   You can use the OpenSSL tool to generate a self-signed SSL certificate.

   openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout nginx.key -out nginx.crt
   

   This command will generate two files: nginx.key (private key) and nginx.crt (self-signed certificate).

2. Create a Dockerfile:

   Create a file named Dockerfile in your project directory with the following content:

   FROM nginx:latest
   
   # Copy the SSL certificate and key to the container
   COPY nginx.crt /etc/nginx/ssl/nginx.crt
   COPY nginx.key /etc/nginx/ssl/nginx.key
   
   # Copy the Nginx configuration file
   COPY nginx.conf /etc/nginx/conf.d/default.conf
   

3. Create Nginx Configuration:

   Create an nginx.conf file in the same directory as your Dockerfile with the following content:

   server {
       listen 443 ssl;
       server_name your_domain.com;  # Change this to your domain name
   
       ssl_certificate /etc/nginx/ssl/nginx.crt;
       ssl_certificate_key /etc/nginx/ssl/nginx.key;
   
       location / {
           root   /usr/share/nginx/html;
           index  index.html index.htm;
       }
   }
   

   Replace your_domain.com with your actual domain name.

4. Build the Docker Image:

   Run the following command in your terminal to build the Docker image:

   docker build -t nginx-ssl .
   

5. Run the Docker Container:

   Finally, run the Docker container using the following command:

   docker run -d -p 443:443 nginx-ssl
   

docker run --name some-nginx -v /some/content:/usr/share/nginx/html:ro -d nginx

docker run –name nginx-ssl -v //home/ubuntu/data:/usr/share/nginx/html:ro -p 443:443 -d nginx-ssl

This maps the container’s port 443 to the host’s port 443.

1. Access the Site:

   Open a web browser and navigate to https://your_domain.com. You might get a security warning due to the self-signed certificate, but you can proceed to the site. The browser will indicate that the connection is not fully secure because the certificate is self-signed.

Remember that using self-signed certificates is not recommended for production environments since they don’t provide the same level of security as trusted certificates issued by a certificate authority. In a production environment, you should obtain a valid SSL certificate from a trusted certificate authority like Let’s Encrypt.
