Using Python-Jenkins¶
The python-jenkins library allows management of a Jenkins server through the Jenkins REST endpoints. Below are examples to get you started using the library. If you need further help take a look at the API reference docs for more details.
Example 1: Get version of Jenkins¶
This is an example showing how to connect to a Jenkins instance and retrieve the Jenkins server version.
import jenkins
server = jenkins.Jenkins('http://localhost:8080', username='myuser', password='mypassword')
version = server.get_version()
print version
The above code prints the version of the Jenkins master running on ‘localhost:8080’
From Jenkins vesion 1.426 onward you can specify an API token instead of your real password while authenticating the user against the Jenkins instance. Refer to the Jenkins Authentication wiki for details about how you can generate an API token. Once you have an API token you can pass the API token instead of a real password while creating a Jenkins instance.
Example 2: Working with Jenkins Jobs¶
This is an example showing how to create, configure and delete Jenkins jobs.
server.create_job('empty', jenkins.EMPTY_CONFIG_XML)
jobs = server.get_jobs()
print jobs
server.build_job('empty')
server.disable_job('empty')
server.copy_job('empty', 'empty_copy')
server.enable_job('empty_copy')
server.reconfig_job('empty_copy', jenkins.RECONFIG_XML)
server.delete_job('empty')
server.delete_job('empty_copy')
# build a parameterized job
# requires creating and configuring the api-test job to accept 'param1' & 'param2'
server.build_job('api-test', {'param1': 'test value 1', 'param2': 'test value 2'})
last_build_number = server.get_job_info('api-test')['lastCompletedBuild']['number']
build_info = server.get_job_info('api-test', last_build_number)
print build_info
Example 3: Working with Jenkins Views¶
This is an example showing how to create, configure and delete Jenkins views.
server.create_view('EMPTY', jenkins.EMPTY_VIEW_CONFIG_XML)
view_config = server.get_view_config('EMPTY')
views = server.get_views()
server.delete_view('EMPTY')
print views
Example 4: Working with Jenkins Plugins¶
This is an example showing how to retrieve Jenkins plugins information.
plugins = server.get_plugins_info()
print plugins
The above example will print a dictionary containing all the plugins that
are installed on the Jenkins server. An example of what you can expect
from the get_plugins_info()
method is documented in the API reference
doc.
Example 5: Working with Jenkins Nodes¶
This is an example showing how to add, configure, enable and delete Jenkins nodes.
server.create_node('slave1')
nodes = get_nodes()
print nodes
node_config = server.get_node_info('slave1')
print node_config
server.disable_node('slave1')
server.enable_node('slave1')
# create node with parameters
params = {
'port': '22',
'username': 'juser',
'credentialsId': '10f3a3c8-be35-327e-b60b-a3e5edb0e45f',
'host': 'my.jenkins.slave1'
}
server.create_node(
'slave1',
nodeDescription='my test slave',
remoteFS='/home/juser',
labels='precise',
exclusive=True,
launcher=jenkins.LAUNCHER_SSH,
launcher_params=params)
Example 6: Working with Jenkins Build Queue¶
This is an example showing how to retrieve information on the Jenkins queue.
server.build_job('foo')
queue_info = server.get_queue_info()
id = queue_info[0].get('id')
server.cancel_queue(id)
Example 7: Working with Jenkins Cloudbees Folders¶
Requires the Cloudbees Folders Plugin for Jenkins.
This is an example showing how to create, configure and delete Jenkins folders.
server.create_job('folder', jenkins.EMPTY_FOLDER_XML)
server.create_job('folder/empty', jenkins.EMPTY_FOLDER_XML)
server.copy_job('folder/empty', 'folder/empty_copy')
server.delete_job('folder/empty_copy')
server.delete_job('folder')
Example 8: Updating Next Build Number¶
Requires the Next Build Number Plugin for Jenkins.
This is an example showing how to update the next build number for a Jenkins job.
next_bn = server.get_job_info('job_name')['nextBuildNumber']
server.set_next_build_number('job_name', next_bn + 50)
