Nếu bạn cần kích hoạt một công việc từ CLI và chờ hoàn thành, bạn có thể sử dụng "Jenkins CLI" (xem tại đây ).
Tuy nhiên jenkins CLI không hỗ trợ các chương trình khuyến mãi nên đối với họ tôi đã đưa ra kịch bản sau:
#!/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/ \
# . \
# '{"name": "prom_param_1", "value": "stringvalue" } , {"name": "prom_param_2", "value": true }'
