I have a domain name mydomain.com registered on amazon route 53.
I have an EC2 instance in which I installed a docker portainer image under 9000 port.
My docker image run perfectly under ec2 public ip address: http://xxx.xxx.xxx.xxx:9000
What I want now is to create a subdomain: portainer.mydomain.com and pointed it to my EC2 portainer instance.
When I try to create a new record set portainer.mydomaon.com and point it to my docker image instance I can't specify the port value.
I know I miss something, I'm on my beginning on DNS domains.
