deployment-tracker

Deployment Tracker

Collect deployment metadata from various deployment engines and forward them along to purpose-driven application endpoints for storage and analysis later.

Outputs include:

1. Logstash (ELK stack) via Redis for log messages
2. Statsd for metrics aggregation
3. SQL database table for long-lived deployment summary information

Installation

npm install deployment-tracker
node deployment-tracker

Note: Not compatible with Node.js versions 4.x

Usage

# Record the start of a deployment
curl -X POST -H 'Content-Type:application/json' http://server:port/v1/deployments/84e803f7-9562-4d95-b828-25b167aea34b -d '{"deployment_id": 84e803f7-9562-4d95-b828-25b167aea34b, "engine": "vagrant_orchestrate", "engine_version": "0.6.3", "host": "localhost", "user": "cbaldauf", "environment": "dev", "package": "test", "package_url": "http://mypackage.mydomain.com", "version": "4.5.6", "arguments": "--strategy parallel" }'

# Record some log messages
curl -X POST -H 'Content-Type: application/json' http://server:port/v1/deployments/84e803f7-9562-4d95-b828-25b167aea34b -d '{"message": "Starting deployment phase 1", "severity": "info"}'

# Record the completion of a deployment
curl -X PUT -H 'Content-Type:application/json' http://server:port/v1/deployments/84e803f7-9562-4d95-b828-25b167aea34b -d '{"deployment_id": "84e803f7-9562-4d95-b828-25b167aea34b", "result": "success", "elapsed_seconds": 234}'

The service also supports tracking deployments on individual servers, using the /v1/deployments/{id}/servers route

Configuration

Configuration lives in the config.js file at the root of the package. Currently the recommendation is to overwrite the file, but support for specifying an alternate file via an environment variable is envisioned.

A sample config might look something like this:

{
  redis :
  {
    host: "myredishost.mydomain.com"
  },
  statsd :
  {
    host: "mystatsdhost.mydomain.com",
    prefix: "deployment-tracker"
  }
}

Redis

The redis output represents a step in the path toward showing up in Logstash (Elastic's ELK stack). Of course, there are other ways to get data into ElasticSearch / LogStash, but deployment-tracker currently only supports redis. If you're interested in a different logging output format or transport mechanism, please open an issue.

Field	Type	Default	Notes
host	string	127.0.0.1	The redis host to send log messages to
port	integer	6379	The redis port to send log messages to
index	string	deployment-tracker	The index name to include in the log message
key	string	logstash	The redis key to which messages are appended
additional_fileds	hash	{ }	A hash of additional fields that will be merged into each log message that is sent to redis

The config.redis object is passed directly to the constructor of the redis client implementation (in this case ioredis), so any of the ioredis connection options should be supported.

{
  redis :
  {
    host : "myredishost.mydomain.com",
    port : 6379,
    index : "deployment-tracker",
    key : "logstash",
    additional_fields :
    {
        foo: "This will be appended to every log message"
        bar: "So will this"
    }
  }
}

Development

1. Clone this repo
2. Spin up required infrastructure by running vagrant up
3. Make changes
4. Test locally using the grunt command

• Alternatively, you can mock the redis endpoint with DEPLOYMENT_TRACKER_MOCK_REDIS=true grunt

1. Spin up a Vagrant box to test the deployment using the vagrant up command
2. File a pull request

TODO:

• Proper Exception Handling / logging
• Configuration instructions and examples
