A Dockerfile with lots of CoAP implementations.
The built image is available at https://registry.hub.docker.com/u/markushx/coap/ . Feel free to modify and sent me your pull requests
Start the image in interactive mode using using
docker run -i -t -p 5683:5683/udp markushx/coap-docker
This command binds your local UDP port for CoAP (5683) to the docker instance.
Start any CoAP application, i.e. Californium:
cd Californium/run
java -jar cf-server-0.18.7-final.jar
Now you can access the CoAP server: coap://127.0.0.1
