# 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

Output that you would get if you had started with `-ti` instead of `d` (for daemon):

[INF] Starting nats-streaming-server[test-cluster] version 0.2.2
[INF] Starting nats-server version 0.9.2
[INF] Starting http monitor on :8222
[INF] Listening for client connections on 0.0.0.0:4222
[INF] Server is ready
[INF] STAN: Message store is MEMORY
[INF] STAN: Maximum of 1000000 will be stored

To use a file based store instead, you would run:

$ docker run -d nats-streaming -store file -dir datastore

[INF] Starting nats-streaming-server[test-cluster] version 0.2.2
[INF] Starting nats-server version 0.9.2
[INF] Starting http monitor on :8222
[INF] Listening for client connections on 0.0.0.0:4222
[INF] Server is ready
[INF] STAN: Message store is FILE
[INF] STAN: Maximum of 1000000 will be stored

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 -ns nats://nats-main:4222 

[INF] Starting nats-streaming-server[test-cluster] version 0.2.2
[INF] STAN: Message store is MEMORY
[INF] STAN: Maximum of 1000000 will be stored

Notice that the output shows that the NATS Server was not started, as opposed to the first output.
