NAME
Jenkins::API - A wrapper around the Jenkins API
VERSION
version 0.14
SYNOPSIS
This is a wrapper around the Jenkins API.
use Jenkins::API;
my $jenkins = Jenkins::API->new({
base_url => 'http://jenkins:8080',
api_key => 'username',
api_pass => 'apitoken',
});
my $status = $jenkins->current_status();
my @not_succeeded = grep { $_->{color} ne 'blue' } @{$status->{jobs}};
# {
# 'color' => 'red',
# 'name' => 'Test-Project',
# 'url' => 'http://jenkins:8080/job/Test-Project/',
# }
my $success = $jenkins->create_job($project_name, $config_xml);
...
ATTRIBUTES
Specify these attributes to the constructor of the Jenkins::API object
if necessary.
base_url
This is the base url for your Jenkins installation. This is commonly
running on port 8080 so it's often something like http://jenkins:8080
api_key
This is the username for the basic authentication if you have it turned
on.
If you don't, don't specify it.
Note that Jenkins returns 403 error codes if authentication is required
but hasn't been specified. A common setup is to allow build statuses to
be read but triggering builds and making configuration changes to
require authentication. Check "response_code" after making a call that
fails to see if it is an authentication failure.
my $success = $jenkins->trigger_build($job_name);
unless($success)
{
if($jenkins->response_code == 403)
{
print "Auth failure\n";
}
else
{
print $jenkins->response_content;
}
}
api_pass
The API token for basic auth. Go to the Jenkins wiki page on
authenticating scripted clients
<https://wiki.jenkins-ci.org/display/JENKINS/Authenticating+scripted+clients>
for information on getting an API token for your user to use for
authentication.
METHODS
check_jenkins_url
Checks the url provided to the API has a Jenkins server running on it.
It returns the version number of the Jenkins server if it is running.
$jenkins->check_jenkins_url;
# 1.460
current_status
Returns the current status of the server as returned by the API. This
is a hash containing a fairly comprehensive list of what's going on.
$jenkins->current_status();
# {
# 'assignedLabels' => [
# {}
# ],
# 'description' => undef,
# 'jobs' => [
# {
# 'color' => 'blue',
# 'name' => 'Jenkins-API',
# 'url' => 'http://jenkins:8080/job/Jenkins-API/'
# },
# 'mode' => 'NORMAL',
# 'nodeDescription' => 'the master Jenkins node',
# 'nodeName' => '',
# 'numExecutors' => 2,
# 'overallLoad' => {},
# 'primaryView' => {
# 'name' => 'All',
# 'url' => 'http://jenkins:8080/'
# },
# 'quietingDown' => bless( do{\(my $o = 0)}, 'JSON::XS::Boolean' ),
# 'slaveAgentPort' => 0,
# 'useCrumbs' => $VAR1->{'quietingDown'},
# 'useSecurity' => $VAR1->{'quietingDown'},
# 'views' => [
# {
# 'name' => 'All',
# 'url' => 'http://jenkins:8080/'
# }
# ]
# }
It is also possible to pass two parameters to the query to refine or
expand the data you get back. The tree parameter allows you to select
specific elements. The example from the Jenkins documentation , tree=>
'jobs[name],views[name,jobs[name]]' demonstrates the syntax nicely.
The other parameter you can pass is depth, by default it's 0, if you
set it higher it dumps a ton of data.
$jenkins->current_status({ extra_params => { tree => 'jobs[name,color]' }});;
# {
# 'jobs' => [
# {
# 'color' => 'blue',
# 'name' => 'Jenkins-API',
# },
# ]
# }
$jenkins->current_status({ extra_params => { depth => 1 }});
# returns everything and the kitchen sink.
It is also possible to only look at a subset of the data. Most urls you
can see on the website in Jenkins can be accessed. If you have a job
named Test-Project for example with the url /job/Test-Project you can
specify the path_parts => ['job', 'Test-Project'] to look at the data
for that job alone.
$jenkins->current_status({
path_parts => [qw/job Test-Project/],
extra_params => { depth => 1 },
});
# just returns the data relating to job Test-Project.
# returning it in detail.
The method will die saying 'Invalid response' if the server doesn't
respond as it expects, or die with a JSON decoding error if the JSON
parsing fails.
get_job_details
Returns detail about the job specified.
$job_details = $jenkins->get_job_details('Test-Project');
# {
# 'actions' => [],
# 'buildable' => bless( do{\(my $o = 0)}, 'JSON::PP::Boolean' ),
# 'builds' => [],
# 'color' => 'disabled',
# 'concurrentBuild' => $VAR1->{'buildable'},
# 'description' => '',
# 'displayName' => 'Test-Project',
# 'displayNameOrNull' => undef,
# 'downstreamProjects' => [],
# 'firstBuild' => undef,
# 'healthReport' => [],
# 'inQueue' => $VAR1->{'buildable'},
# 'keepDependencies' => $VAR1->{'buildable'},
# 'lastBuild' => undef,
# 'lastCompletedBuild' => undef,
# 'lastFailedBuild' => undef,
# 'lastStableBuild' => undef,
# 'lastSuccessfulBuild' => undef,
# 'lastUnstableBuild' => undef,
# 'lastUnsuccessfulBuild' => undef,
# 'name' => 'Test-Project',
# 'nextBuildNumber' => 1,
# 'property' => [],
# 'queueItem' => undef,
# 'scm' => {},
# 'upstreamProjects' => [],
# 'url' => 'http://jenkins-t2:8080/job/Test-Project/'
# }
The information can be refined in the same way as "current_status"
using extra_params.
view_status
Provides the status of the specified view. The list of views is
provided in the general status report.
$jenkins->view_status('MyView');
# {
# 'busyExecutors' => {},
# 'queueLength' => {},
# 'totalExecutors' => {},
# 'totalQueueLength' => {}
# }
# {
# 'description' => undef,
# 'jobs' => [
# {
# 'color' => 'blue',
# 'name' => 'Test',
# 'url' => 'http://jenkins-t2:8080/job/Test/'
# }
# ],
# 'name' => 'Test',
# 'property' => [],
# 'url' => 'http://jenkins-t2:8080/view/Test/'
# }
This method allows the same sort of refinement as the "current_status"
method. To just get the job info from the view for example you can do
essentially the same,
use Data::Dumper;
my $view_list = $api->current_status({ extra_params => { tree => 'views[name]' }});
my @views = grep { $_ ne 'All' } map { $_->{name} } @{$view_list->{views}};
for my $view (@views)
{
my $view_jobs = $api->view_status($view, { extra_params => { tree => 'jobs[name,color]' }});
print Dumper($view_jobs);
}
# {
# 'jobs' => [
# {
# 'color' => 'blue',
# 'name' => 'Test'
# }
# ]
# }
trigger_build
Trigger a build,
$success = $jenkins->trigger_build('Test-Project');
If you need to specify a token you can pass that like this,
$jenkins->trigger_build('Test-Project', { token => $token });
Note that the success response is simply to indicate that the build has
been scheduled, not that the build has succeeded.
trigger_build_with_parameters
Trigger a build with parameters,
$success = $jenkins->trigger_build_with_parameters('Test-Project', { Parameter => 'Value' } );
The method behaves the same way as trigger_build.
build_queue
This returns the items in the build queue.
$jenkins->build_queue();
This allows the same extra_params as the "current_status" call. The
depth and tree parameters work in the same way. See the Jenkins API
documentation for more details.
The method will die saying 'Invalid response' if the server doesn't
respond as it expects, or die with a JSON decoding error if the JSON
parsing fails.
load_statistics
This returns the load statistics for the server.
$jenkins->load_statistics();
# {
# 'busyExecutors' => {},
# 'queueLength' => {},
# 'totalExecutors' => {},
# 'totalQueueLength' => {}
# }
This also allows the same extra_params as the "current_status" call.
The depth and tree parameters work in the same way. See the Jenkins API
documentation for more details.
The method will die saying 'Invalid response' if the server doesn't
respond as it expects, or die with a JSON decoding error if the JSON
parsing fails.
create_job
Takes the project name and the XML for a config file and gets Jenkins
to create the job.
my $success = $api->create_job($project_name, $config_xml);
project_config
This method returns the configuration for the project in XML.
my $config = $api->project_config($project_name);
set_project_config
This method allows you to set the configuration for the project using
XML.
my $success = $api->set_project_config($project_name, $config);
delete_project
Delete the project from Jenkins.
my $success = $api->delete_project($project_name);
general_call
This is a catch all method for making a call to the API. Jenkins is
extensible with plugins which can add new API end points. We can not
predict all of these so this method allows you to call those functions
without needing a specific method.
general_call($url_parts, $args);
my $response = $api->general_call(
['job', $job, 'api', 'json'],
{
method => 'GET',
extra_params => { tree => 'color,description' },
decode_json => 1,
expected_response_code => 200,
});
# does a GET /job/$job/api/json?tree=color%2Cdescription
# decodes the response as json
# dies if a 200 response isn't returned.
The arguments hash can contain these elements,
* method
Valid options are the HTTP verbs, make sure they are in caps.
* extra_params
Pass in extra parameters the method expects.
* decode_json
Defaulted to true.
* expected_response_code
Defaulted to 200
response_code
This method returns the HTTP response code from our last request to the
Jenkins server. This may be useful when an error occurred.
response_content
This method returns the content of the HTTP response from our last
request to the Jenkins server. This may be useful when an error occurs.
BUGS
The API wrapper doesn't deal with Jenkins installations not running
from the root path. I don't actually know if that's an install option,
but the internal url building just doesn't deal with that situation
properly. If you want that fixing a patch is welcome.
Please report any bugs or feature requests to through the web interface
at https://github.com/colinnewell/Jenkins-API/issues/new. I will be
notified, and then you'll automatically be notified of progress on your
bug as I make changes.
