Need help setting up i2p in a Docker container

I’m looking to try out i2p but I’m having trouble getting it going.

I have a docker-compose container going with this docker-compose.yml:

<span style="color:#63a35c;">version</span><span style="color:#323232;">: </span><span style="color:#183691;">"3.5"
</span><span style="color:#63a35c;">services</span><span style="color:#323232;">:

</span><span style="color:#323232;">            - </span><span style="color:#183691;">54321:12345/udp

</span><span style="color:#323232;">            - </span><span style="color:#183691;">IP_ADDR=0.0.0.0
</span><span style="color:#323232;">            - </span><span style="color:#183691;">JVM_XMX=1024m
</span>

The container starts up and the log outputs:

<span style="color:#323232;">$ docker logs i2p-i2p-1 
</span><span style="color:#323232;">Starting I2P
</span><span style="color:#323232;">[startapp] Running in container
</span><span style="color:#323232;">[startapp] setting reachable IP to container IP 0.0.0.0
</span><span style="color:#323232;">Starting I2P 2.4.0-0
</span>

But when I try to access the console, I’m seeing:

<span style="color:#323232;">$ curl localhost:7657
</span><span style="color:#323232;">curl: (56) Recv failure: Connection reset by peer
</span>

Is there anything else that I need to do here?
