Simple TCP Server

A very simple game server, for the purposes of testing a TCP based server on Agones.

Server

Starts a server on port 7654 by default. Can be overwritten by PORT env var or port flag.

When it receives a text message ending with a newline, it will send back "ACK:" as an echo.

If it receives the text "EXIT", then it will sys.Exit(0)

Firewalls

If you plan to access your server remotely, you may need to open up a hole in your firewall.

For example, if you created a cluster running on Google Kubernetes Engine following the installation guide, you can create a firewall rule to allow TCP traffic to nodes tagged as game-server via ports 7000-8000.

gcloud compute firewall-rules create game-server-firewall-tcp \
  --allow tcp:7000-8000 \
  --target-tags game-server \
  --description "Firewall to allow game server udp traffic"
