Hi @bsscdt ,

Try this command:

docker run -p 80:80 -p 443:443 --name nginx -d nginx

The --name should be the name of your docker container.If you don’t pull nginx yet,also run this before the command I mentioned to mapping 80/443 ports:

docker pull nginx

Step 5 — Allowing Other Connections

At this point, you should allow all of the other connections that your server needs to respond to. The connections that you should allow depend on your specific needs. You already know how to write rules that allow connections based on an application profile, a service name, or a port; you already did this for SSH on port 22. You can also do this for:

HTTP on port 80, which is what unencrypted web servers use, using sudo ufw allow http or sudo ufw allow 80
HTTPS on port 443, which is what encrypted web servers use, using sudo ufw allow https or sudo ufw allow 443
Apache with both HTTP and HTTPS, using sudo ufw allow ‘Apache Full’
Nginx with both HTTP and HTTPS, using sudo ufw allow ‘Nginx Full’
