I have a Dgrpah set up with one zero and five alphas. Is it necessary for the alphas 8080 port to be offset or can they stay at 8080? . Each alphas host name is unique

Keeping the port 8080 for alphas will just lead to ambiguity as to which alpha is actually listening on that port. Go through this link to learn more about single host setups → https://dgraph.io/docs/deploy/single-host-setup/

If each Alpha or Zero node lives in its own host with his own IP. You can let it without offset.
e.g:
Zero-0 = 192.168.1.10:5080
Zero-1 = 192.168.1.11:5080
Zero-2 = 192.168.1.12:5080
Alpha-0 = 192.168.1.20:8080
Alpha-1 = 192.168.1.21:8080
Alpha-2 = 192.168.1.22:8080
Alpha-3 = 192.168.1.23:8080
Alpha-4 = 192.168.1.24:8080
Alpha-5 = 192.168.1.25:8080
if you have an internal naming server(DNS) you can use addresses instead of IPs.
see this example with docker and NGINX

## First thing
> One thing that I have to mention is that this Gist is a personal test env. Some things can be configured in a way that you don't want it to be.
Add the host information in the host file to your system (or do some DNS config)
Go to http://grafana_http:3000/ and import the grafana_dgraph.json
You have HTTP and GRPC endpoints.

They each run on their own EC2 instance/host and use DNS
thankyou for the clarification
thanks
