jenks 0.2.3

a jenkins command-line tool

Jenks is a command-line tool, designed to interact with a remote jenkins host, including:

Start by either filling out a configuration file, or adding a job with:

$ jenks config -a http://localhost:8080/job/bar/

After that, you can get status information with:

$ jenks 0: localhost, foo (last build #7) SUCCESS 1: localhost, bar (last build #3) SUCCESS

Jenks works with unique keys assigned to each job, rather than job names. You can see it in the above example: it’s the 0 and 1 at the beginning of the line.

You can trigger the job foo from above with:

$ jenks trigger :0

Get the latest build information from the job bar with:

$ jenks build :1

Get information about multiple jobs simultaneously by adding multiple keys:

$ jenks -l :10

And you can pull up more information with:

$ jenks docs

Installation

  • since jenkinsapi (the main dependency) is only python2 compatible, jenks is currently only python2 compatible.

There’s a few ways to install Jenks.

Through pip:

pip install jenks
pip install http://github.com/toumorokoshi/jenks/tarball/master

Through sprinter:

sprinter install https://raw.github.com/toumorokoshi/jenks/master/sprinter.cfg

Configuration (.jenksrc)

Jenks requires a .jenksrc file to configure itself. Jenks searches in the current directory and moves up parent directories until it finds one.

A .jenksrc file should be a yaml file, with a dictionary of hosts and some keys for configuration.

Here is an example .jenksrc file with all options:

'localhost':
  url: 'http://localhost:8080/'
  jobs:
    - foo
    - bar
'http://jenkins.local':
  jobs:
    - baz

the in-depth configuration for a host is:

  • url: the url to the host. If the url doesn’t exist, the host name is used as the url
  • jobs: a list of job names to add to the list

Keys

By default, Jenks will perform operations on all jobs in the configuration. However, you can restrict the jobs to specific ones by passing a list of keys. Each job is given a unique key generated by jenks. For example, using -l on the example configuration will yield:

$ jenks -l
0 http://jenkins.local baz
1 localhost foo
2 localhost bar

The character at the beginning of each line is the key. Each key is a single character in the set: [0-9a-zA-Z]. You can pass in a string of characters prefixed with a colon to get information about those:

$ jenks -l :20
0 http://jenkins.local baz
2 localhost bar

You can pass in keys as:

  • an argument:

    $ jenks -c :0
    
  • with standard in:

    $ echo '0' | jenks
    

Job Codes

You can also reference jobs from the jenksrc by name, using the job code syntax. The job code syntax looks like:

<host_key>/<job_name>
localhost/bar

For example, here’s how to get information about the latest build of a job by job code:

$ jenks build localhost/bar

Examples

Ones of Jenks’ goals is to follow the Unix philosophy of doing one thing and doing it well. By being a modular part and supporting stdin, it’s possible to chain Jenks with other commands.

For example, here’s a command that only lists status of jobs whose host or job name match a specific regex:

$ jenks -l | grep "foo" | cut -d ' ' -f 1 | jenks
0: localhost, foo (last build #7) SUCCESS

Monitor the status of your Jenkins jobs:

$ watch jenks
