A basic UDP mirror server that dumps in STDOUT anything you send to it. Useful to test your application or metrics backends like DataDog.
$ docker pull eexit/dumudp-server
$ docker run -dp 8125:8125/udp --name dumudp-server eexit/dumudp-server
Send your UDP packets:
$ echo -n "dumudp-server.test.counter:1|c" | nc -w 1 -u 127.0.0.1 8125
Check on the container log:
$ docker logs -f dumudp-server
> [email protected] start /app
> node server.js
Started to listen on 0.0.0.0:8125...
172.17.0.1:38722 >>> dumudp-server.test.counter:1|c
172.17.0.1:43596 >>> dumudp-server.test.counter:1|c
172.17.0.1:39459 >>> dumudp-server.test.counter:1|c
Default port is 8125 but you can change the port by running the container like this (here set the port 28900 up):
$ docker run -d --name dumudp-server -e PORT=28900 -p 28900:28900/udp eexit/dumudp-server
