यदि आपको सीएलआई से नौकरी ट्रिगर करने की आवश्यकता है और इसके पूरा होने की प्रतीक्षा करें तो आप "जेनकिंस सीएलआई" ( यहां देखें ) का उपयोग कर सकते हैं ।
हालाँकि jenkins CLI पदोन्नति का समर्थन नहीं करता है इसलिए उनके लिए मैं निम्नलिखित स्क्रिप्ट के साथ आया:
#!/bin/bash
# Trigger a promotion and wait for its completion
#
# For triggering jobs jenkins cli is sufficient: https://support.cloudbees.com/hc/en-us/articles/228392127-How-to-wait-for-build-to-finish-when-triggering-from-CLI-
#
# The script is dependent on the current jenkins implementation of:
# - the promotion web page (links for triggering/re-executing the promotions)
# - the behaviour of the XML of the promotion status
#
# The behaviour of the job run status XML is:
# - if the the promotion is not yet been triggered than the response is 404 not found
# - is the the promotion has been triggered
# - ... but it's still waiting for an executor: the response is 404 not found or <duration> is empty
# - ... and has started: <duration> is empty or 0
# - ... and it's finished: <duration> is a non-zero number
#
#
# run syntax:
# ./trigger_promotion_and_wait_for_completion.sh \
# <job_name> \
# <job_run_number_to_promote> \
# <promotion_name> \
# <jenkins_user> \
# <jenkins_pwd> \
# <jenkins_url> \
# <script_workspace_folder> \
# '{"name": "prom_param_1", "value": "stringvalue" } , {"name": "prom_param_2", "value": true }'
#
# example:
# ./trigger_promotion_and_wait_for_completion.sh \
# job1 \
# 22 \
# promotion1 \
# admin \
# password \
# http://localhost:8080/jenkins/ \
