Managing Jenkins Jobs with the python‑jenkins API

This guide introduces the python-jenkins library (available on PyPI) for interacting with a Jenkins server via its REST API using Python 3.7.

Key capabilities include creating, copying, deleting, updating jobs; managing builds, nodes, credentials, views, plugins; retrieving configuration and status information; and performing administrative actions such as quiet‑down and script execution.

Typical workflow starts with installing the library ( pip install python-jenkins==1.6.0 ), creating a Jenkins object, and then calling methods like create_job , copy_job , build_job , etc.

Do‑operations (actions) are grouped in tables in the original article; for example, job operations use methods create_job , disable_job , delete_job , copy_job , enable_job , job_exists , jobs_count , upsert_job . Similar groups exist for builds, credentials, views, nodes, promotions, queue handling, Jenkinsfile syntax checking, and updates.

Get‑operations (queries) include methods such as get_all_jobs , get_job_info , get_build_info , get_credential_info , get_node_info , get_plugin_info , get_version , get_whoami , and others.

Update operations cover actions like quiet_down , reconfig_credential , reconfig_job , reconfig_node , reconfig_view , rename_job , run_script , and set_next_build_number .

Demo example : after creating a sample job, the tutorial shows how to retrieve its config.xml , duplicate the job, and verify creation with server.job_exists("demo-test-02") . It also provides a full script that logs into Jenkins, copies a template job, replaces a parameter value (e.g., changing <defaultValue>svn</defaultValue> to <defaultValue>git</defaultValue> ), and creates a new job.

Running the script produces console output confirming the new job’s existence and displays the generated XML configuration, illustrating how to automate project provisioning in a CI/CD environment.
