Do you have an insane number of jenkins and you want to build on all of them? This is for you. The code makes the build one at a time. I shall make it run in parallel.

Jenkins_Multi_Build.py

def build_jenkins(j_user, j_pass, j_url, job_name):
	"""
	    # https://github.com/stackforge/python-jenkins
	    # http://python-jenkins.readthedocs.org/en/latest/index.html
	"""
	import time
	from jenkins import Jenkins
	
	# set the jenkins object
	j = Jenkins(j_url, j_user, j_pass)

	if j.job_exists(job_name) is True:
		j.build_job(job_name)
		print("\n Build command sent to Jenkins: %s \n"%j_url)
		print("Wait for the build to complete....")
		time.sleep(15)

		last_b = j.get_job_info(job_name)['lastCompletedBuild']['number']
		last_successful_b = j.get_job_info(job_name)['lastSuccessfulBuild']['number']
		# print last_b , last_successful_b #for debugging
		# print "Take extra build info from this:\n" , j.get_job_info(job_name) # for debugging

		print "Checking last build ... "
		print "Last build : %s" % last_b
		print "Last successful build : %s" % last_successful_b, "\n"

		# time.sleep(10)
		if last_b == last_successful_b:
			print "-- Build success --"
		else:
			print "Failed build :["
			
# Build all locust slaves
jenkins_urls = []
for i in range(1,11):
	# create the jenkins url
	jenkins_url = "http://host%s.site.com:8686/"%i
	# add the jenkins url to the list
	jenkins_urls.append(jenkins_url)
	# print jenkins_urls #for debugging

for url in jenkins_urls:
	build_jenkins(j_user="username", j_pass="password", j_url=url, job_name='JobName')

Note to myself: Make it run in parallel ! :]
