# Dockerfile for gnatsd

[gnatsd](https://github.com/apcera/gnatsd) is a high performance NATS server. This project contains a Dockerfile and an example configuration file to run gnatsd in a docker container.

## Usage

```

$ REGISTRY_ID=$(docker run -d -p 4222:4222 -p 8222:8222 -v $(pwd):/config -v $(pwd)/log:/log drnic/gnatsd)

```

See [Build from Dockerfile](#build-from-dockerfile) for instructions on modifying and building the Docker image again from the Dockerfile.

You can now test its internal state:

```

$ curl http://localhost:8222/varz

{

  "start": "2014-02-10T08:07:38.263753468Z",

  "options": {

    "max_connections": 65536,

    "user": "nats",

    "ping_interval": 120000000000,

    "ping_max": 2,

    "http_port": 8222,

    "ssl_timeout": 0.5,

    "max_control_line": 1024,

    "max_payload": 1048576

  },

  "mem": 3903488,

  "cores": 1,

  "cpu": 0,

  "connections": 0,

  "in_msgs": 0,

  "out_msgs": 0,

  "in_bytes": 0,

  "out_bytes": 0,

  "uptime": "1m12.219043078s"

}

$ curl http://localhost:8222/connz

{

  "num_connections": 0,

  "connections": []

}

```

You can play with NATS using the CLI commands installed via RubyGems (known to work on Ruby 1.9.3):

```

$ gem install nats

$ nats-sub '>' -s nats://nats:T0pS3cr3t@localhost:4222

Listening on [>]

```

Then in another terminal:

```

$ nats-pub 'some.channel' 'hello world' -s nats://nats:T0pS3cr3t@localhost:4222

Published [test.this] : 'hello world'

```

And in the `nats-sub` terminal it will show:

```

[#1] Received on [test.this] : 'hello world'

```

The `/connz` health endpoint will show the running `nats-sub` connection:

```

$ curl http://localhost:8222/connz

{

  "num_connections": 1,

  "connections": [...]

}

```

## Build from Dockerfile

```

$ git submodule update --init

$ docker build -t gnatsd .

$ REGISTRY_ID=$(docker run -d -p 4222:4222 -p 8222:8222 -v $(pwd):/config -v $(pwd)/log:/log gnatsd)

```
