Nestor

Nestor is a Jenkins CLI and node.js client.

This is handy for Jenkins users who prefer to touch type on the command line over GUI and mouse clicks on the browser. It also serves as an alternative to Jenkins Java CLI where Nestor has shorter commands and executes faster.

Installation

npm install -g nestor

Usage

Trigger a build:

nestor build <job>

Trigger a parameterised build:

nestor build <job> ["param1=value1&param2=value2"]

Trigger a build followed by console output:

nestor build --console <job>

Trigger a build, wait for 5 seconds, then display console output:

nestor build --pending 5000 --console <job>

Trigger a parameterised build followed by console output:

nestor build <job> ["param1=value1&param2=value2"] --console

Display latest build console output:

nestor console <job>

Display console output of a particular build number:

nestor console <job> [build_number]

Stop currently running build:

nestor stop <job>

View status of all jobs:

nestor dashboard

View job status reports:

nestor job <job>

Enable a job:

nestor enable <job>

Disable a job:

nestor disable <job>

Create a new job with a specified config.xml:

nestor create <job> <path/to/config.xml>

Update an existing job with a specified config.xml:

nestor update <job> <path/to/config.xml>

Copy an existing job1 to a new job2:

nestor copy <job1> <job2>

Delete an existing job:

nestor delete <job>

Fetch the config.xml of an existing job: (experimental)

nestor config <job>

Create a new view with a specified config.xml: (experimental)

nestor create-view <view> <path/to/config.xml>

Update an existing view with a specified config.xml: (experimental)

nestor update-view <view> <path/to/config.xml>

Fetch the config.xml of an existing view: (experimental)

nestor fetch-view-config <view>

View queued jobs:

nestor queue

View executors' status (running builds):

nestor executor

Discover Jenkins instance running on a specified host:

nestor discover <host>

View Jenkins version number:

nestor ver

View builds feed of all jobs:

nestor feed

View builds feed of a job:

nestor --job <job> feed

Monitor build status and notify Ninja Blocks RGB LED device:

export NINJABLOCKS_TOKEN=<token_from_https://a.ninja.is/hacking>
nestor ninja

Note: <job> in the examples is a part of your Jenkins job URL after the first job/.

For example, if you use nested folders on Jenkins and your URL is /job/myproject/job/releases/job/master, then you should pass myproject/job/releases/job/master as <job>.

Programmatically:

var nestor = new (require('nestor'))(
  'http://user:pass@host:port/path'
);

// trigger a standard build
nestor.buildJob('job', '', function (err, result) {
});

// trigger a parameterised build
nestor.buildJob('job', 'param1=value1&param2=value2', function (err, result) {
});

Check out lib/jenkins for other available methods.

NOTE: Starting from version 2.0.0, Nestor started using Swaggy Jenkins as an API client. You can still use Nestor programmatically, but it's much better and cleaner if you use Swaggy Jenkins instead.

Configuration

Jenkins URL

Set Jenkins URL in JENKINS_URL environment variable (defaults to http://localhost:8080):

(*nix)

export JENKINS_URL=http://user:pass@host:port/path

(Windows)

set JENKINS_URL=http://user:pass@host:port/path

As an alternative to password, you can use Jenkins API token instead. Jenkins API token can be found on Jenkins user configuration page.

If http_proxy or https_proxy environment variable is set, then Nestor will automatically use it.

If you want authentication details to be prompted interactively:

JENKINS_URL=http://host:port/path nestor --interactive build job

Jenkins URL can also be specified as an arg:

nestor --url http://user:pass@host:port/path dashboard

SSL client certificate authentication

Set JENKINS_CERT and JENKINS_KEY

(*nix)

export JENKINS_CERT=certificate.pem
export JENKINS_KEY=key.pem

(Windows)

set JENKINS_CERT=certificate.pem
set JENKINS_KEY=key.pem

When you have both key and certificate in one file, currently you have to set both ENV variables to the same file

(*nix)

export JENKINS_CERT=combined.pem
export JENKINS_KEY=combined.pem

(Windows)

set JENKINS_CERT=combined.pem
set JENKINS_KEY=combined.pem

It is possible to specify a custom CA. Just set the JENKINS_CA env variable

(*nix)

export JENKINS_CA=custom.ca.pem

(Windows)

set JENKINS_CA=custom.ca.pem

Translation

To add a new language translation:

1. Create a locale JSON file in conf/locales/ directory, with the locale's ISO 639-1 code as file name.
2. Copy paste the content of the existing non-English locale file (anything other than en.json) and modify the translation values accordingly.
3. Test by executing a command with LANG environment variable, e.g. LANG=<code> nestor dashboard
