UDP Proxy with Service Activation Support

Why required -

Swiftwave uses HAProxy as ingress and it can handle TCP/HTTP traffic. But it can't handle UDP traffic. So, we need a UDP proxy to handle UDP traffic.

You may thought why we not using Docker Swarm Ingress for UDP traffic.

The reason is

• we need some control over the port mapping.
• we need something which can monitor traffic and can take action based on that. (future requirement)
• we have some feature in our roadmap which required UDP proxy. (future requirement)

How it works -

• It will listen on a port and forward the traffic to the destination based on the configuration.
• It will have a backup mechanism to alert swiftwave if service is unreachable. (future requirement)
• Will support runtime configuration change.
• Will only managed over unix socket.

Environment Variables -

• SOCKET_PATH - Path of the unix socket. Default: /etc/udpproxy/api.sock
• RECORDS_PATH - Path of the records file. Default: /var/lib/udpproxy/records
