UdpCommunication

Simple UDP listener and receivers deployed into the Docker containers

UDP listener

UDP listener is using UdpClient to listen for incoming datagram packets on specific local port.

Publish

Publish builds the project in Release configuration for target framework .net 7 and linux x64 runtime.

Binaries are published to C:\Temp\UdpCommunication\UdpListener. Change the path based on your environment and needs.

Docker compose

version: "3"
services:
  udplistener:
    build:
      context: .
      dockerfile: DockerfileUdpListener
    volumes:
      - C:\Temp\UdpCommunication\UdpListener:/opt/mm/udplistener
    networks:
      static-network:
        ipv4_address: 172.20.0.4
networks:
  static-network:
    ipam:
      config:
        - subnet: 172.20.0.0/16

Compose file maps the local path C:\Temp\UdpCommunication\UdpListener to path /opt/mm/udplistener in the docker container.

If you changed the output path for publish you need to change the volume path in compose file.

Docker file

FROM debian:latest

WORKDIR /opt/mm/udplistener
#Add missing env property
ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1
ENTRYPOINT ["./UdpListener","42123"]

Docker file contains only entrypoint with execution of UdpListener from mapped folder with one parameter which specifies the local port for listening on upcoming datagrams.

Docker command

To build docker container and start it run the following commands

docker-compose -f <path>\docker-compose-listener.yml build
docker-compose -f <path>\docker-compose-listener.yml up

UDP sender

UDP sender sends datagrams to the specified endpoint.

Publish

Publish builds the project in Release configuration for target framework .net 7 and linux x64 runtime.

Binaries are published to C:\Temp\UdpCommunication\UdpSender. Change the path based on your environment and needs.

Docker compose

networks:
  static-network:
    ipam:
      config:
        - subnet: 172.20.0.0/16

Compose file maps the local path C:\Temp\UdpCommunication\UdpSender to path /opt/mm/udpsender in the docker container.

If you changed the output path for publish you need to change the volume path in compose file.

Docker file

FROM debian:latest

WORKDIR /opt/mm/udpsender
#Add missing env property
ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1
#Parameters: ip of udp listener and its port
ENTRYPOINT ["./UdpSender","172.20.0.4","42123"]

Docker file contains only entrypoint with execution of UdpSender from mapped folder with two parameters. First parameter specifies the remote endpoint IP address and the second one specifies port.

Docker command

To build docker container and start it run the following commands

docker-compose -f <path>\docker-compose-sender.yml build
docker-compose -f <path>\docker-compose-sender.yml up
