Go Random Chat

Fast and scalable real-time random chat written in go.

Features:

Real-time communication and efficient websocket handling using Melody.
Stateless chat servers with the help of Redis Pub/Sub.
- We are not using Redis Stream here since at-most-once delivery is enough for transient messages. Thus, there is chance of data loss during matching and chatting stages.
- If you want at-least-once delivery for message fan-out, please consider using brokers such as NATS and Kafka. The following examples show how to interact with these brokers using go client.
  - https://github.com/minghsu0107/NATS-PubSub
  - https://github.com/minghsu0107/Kafka-PubSub
High performance and linear scalability with the help of Redis Cluster.
User Matching with idempotency.
Responsive web design.

Usage

./run.sh run

This will spin up all services declared in docker-compose.yaml. Visit localhost and you will see the application home page.

Environment variables:

HTTP_PORT: Opened port of HTTP server
REDIS_PASSWORD: Redis password
REDIS_ADDRS: Redis node addresses
REDIS_EXPIRATION_HOURS: The expiration of all Redis keys (in hour). Default: 24
MAX_ALLOWED_CONNS: Max allowed connections to the server. Default: 200
MAX_MSGS: Max number of messages in a channel. Default: 500

Hi,

Thanks! This is a really helpful chat service. I want to deploy this service on a kubernetes cluster, so I am looking for Kubernetes manifest files for each of the microservices (if you had implemented any). If not, can you point me to how can I start writing them on my own?

I tried to use kompose to convert the docker-compose.yaml file to kubernetes manifest files for each service but that gives several errors such as ImagePullBackOff, CrashLoopBackOff etc.

Thanks!
