Distributed Message Service Cluster for Service Registration and Discovery via ETCD

Aim

This project is to provide a reliable message service，By making this project into a docker image, you can quickly build a distributed message service cluster on the docker container platform.

You can also customize your message service cluster by modifying the code.

How to use

• Generate discovery url

curl -s http://discovery.etcd.io/new?size=3
// https://discovery.etcd.io/9c7d8d23b7d883e5a3348ae66fc85ec7

• Modify start.sh to replace the discovery url

nohup /tmp/etcd/etcd  \
     -name proxy \
     -proxy on  \
     -listen-client-urls http://0.0.0.0:2370  \
     -discovery https://discovery.etcd.io/9c7d8d23b7d883e5a3348ae66fc85ec7 >> /tmp/etcd/output.log 2>&1 & echo $! > run.pid

node ./build/index.js

• Build and launch the docker container

docker build -t im-server:latest .
docker run -d -p 8080:8080 im-server

Client authentication mode

1. default

   To allow any client access, the Token required to connect to the server must be generated in conjunction with secret.user in the server configuration.

2. strict

   Allow only token authenticated client access。

Token generating rule

const token = md5(“${secretKey}_${uid},${ipAddress},${loginTime}”).substr(0, 8)
