NATS Streaming: A high-performance cloud native messaging streaming system.
nats-streaming
is a high performance streaming server for the NATS Messaging System.
# Run a NATS Streaning server
# Each server exposes multiple ports
# 4222 is for clients.
# 8222 is an HTTP management port for information reporting.
# use -p or -P as needed.
$ docker run -d nats-streaming

You can also connect to a remote NATS Server running in a docker image.
First, run NATS Server:
$ docker run -d --name=nats-main nats
Now, start the Streaming server and link it to the above docker image:
$ docker run -d --link nats-main nats-streaming -store file -dir datastore -ns nats://nats-main:4222
