NATS: A high-performance cloud native messaging system.

nats is a high performance server for the NATS Messaging System.

Example usage

# Run a NATS server
# Each server exposes multiple ports
# 4222 is for clients.
# 8222 is an HTTP management port for information reporting.
# 6222 is a routing port for clustering.
#
# To actually publish the ports when running the container, use the Docker port mapping
# flag "docker run -p <hostport>:<containerport>" to publish and map one or more ports,
# or the -P flag to publish all exposed ports and map them to high-order ports.
#
# This should not be confused with the NATS Server own -p parameter.
# For instance, to run the NATS Server and have it listen on port 4444,
# you would have to run like this:
#
#   docker run -p 4444:4444 arm32v5/nats -p 4444
#
# Or, if you want to publish the port 4444 as a different port, for example 5555:
#
#   docker run -p 5555:4444 arm32v5/nats -p 4444
#
# To enable NATS JetStream, use the -js flag:
#
#   docker run -p 4222:4222 arm32v5/nats -js
#
# And, to persist JetStream data to a volume you can use the -v and -sd flags.
# Keep in mind that -v is a Docker flag, while -js and -sd are NATS Server flags:
#
#   docker run -p 4222:4222 -v nats:/data arm32v5/nats -js -sd /data
#
# Check "docker run" for more information.

The server will load the configuration file below. Any command line flags can override these values.

Default Configuration File

# Client port of 4222 on all interfaces
port: 4222

# HTTP monitoring port
monitor_port: 8222

# This is for clustering multiple servers together.
cluster {
  # It is recommended to set a cluster name
  name: "my_cluster"

  # Route connections to be received on any interface on port 6222
  port: 6222

  # Routes are protected, so need to use them with --routes flag
  # e.g. --routes=nats-route://ruser:T0pS3cr3t@otherdockerhost:6222
  authorization {
    user: ruser
    password: T0pS3cr3t
    timeout: 2
  }

  # Routes are actively solicited and connected to from this server.
  # This Docker image has none by default, but you can pass a
  # flag to the nats-server docker image to create one to an existing server.
  routes = []
}
