How to start Rancher with installed NGINX which is using port 443?

1

I have a EC2 machine Ubuntu 20 installed with nginx as well, docker installed, running some applications in there behind a reverse proxy. Problem is when I run sudo docker run --privileged -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher

I get error: docker: Error response from daemon: driver failed programming external connectivity on endpoint rancher-server (7d5a00a9ab00851a7f6417f601e01a80d31668b10e564aeb88896fa2f10cb850): Error starting userland proxy: listen tcp4 0.0.0.0:443: bind: address already in use.

Just to make sure, I am using letsencrypt certificates.
What should I do in such case?

You change the -p, but will have to choose one or the other. The LetsEncrypt http-01 challenge only works on the standard port.

docker run -d --restart=unless-stopped -p 8080:80 -p 8443:443 --privileged --name=rancher-server rancher/rancher --acme-domain mydomain.com
this is what I tried but didnt manage to get it working yet…when I checked rancher container logs, its not running properly, there is repeating sth like this over and over:

And what do you mean by using one or the other?

You don’t have enough storage free so it’s trying to make some…

You cannot use both an alternate port and the Let’sEncrypt support built in to the server. It only works on the standard port.

So I will have to remove nginx from the server itself and use it in a container?
