Lightweight Machine to Machine (LWM2M) Demo

This repository deploys an environment for testing Lightweight M2M using Eclipse Leshan.

Prerequisite

• Docker Compose CLI plugin

Instructions

Run the following commands to generate x509 private keys and self-signed certificates in DER format for both client and server (based on instructions here) in the .certs directory:

mkdir .certs

# server private key and cert with CN=leshan-server
openssl ecparam -out .certs/xprik.pem -name prime256v1 -genkey
openssl pkcs8 -topk8 -inform PEM -outform DER -in .certs/xprik.pem -out .certs/xprik.der -nocrypt
openssl req -x509 -new -key .certs/xprik.pem -sha256 -days 36500 \
                    -subj '/CN=leshan-server' \
                    -outform DER -out .certs/xcert.der

# client private key and cert with CN=leshan-client
openssl ecparam -out .certs/cprik.pem -name prime256v1 -genkey
openssl pkcs8 -topk8 -inform PEM -outform DER -in .certs/cprik.pem -out .certs/cprik.der -nocrypt
openssl req -x509 -new -key .certs/cprik.pem -sha256 -days 36500 \
                    -subj '/CN=leshan-client' \
                    -outform DER -out .certs/ccert.der

Build the L2M2M client and server images:

docker compose build

Deploy the environment which contains the following:

• a Leshan server
• a Leshan client registering via CoAP (coap://)
• an endpoint provisioner which configures leshan-client as a secure x509 endpoint on the Leshan server (required for registration via CoAP over DTLS)
• a Leshan client registering via CoAP over DTLS (coaps://)

docker compose up

Lastly, browse to Leshan server web UI and you should see two clients registered.
