Calling a Jenkins build from outside of Jenkins?
JenkinsJenkins Problem Overview
I am new to Jenkins, and I'm not sure if this is possible, but I would like to set up a web interface where somebody could click "Start Job" and this will tell Jenkins to start a particular build job.
Does Jenkins have a webservice that would allow such a thing? If so, what would be a simple example?

Solution 1 - Jenkins
Here is a link to the documentation: Jenkins Remote Access API.
Check out the Submitting jobs section.
In your job configuration you setup a token and then create a POST request to JENKINS_URL/job/JOBNAME/build?token=TOKEN. That's probably the most basic usage.
Solution 2 - Jenkins
Jenkins has support for parameterized build as well.
So, if you want to pass parameters for configurable build generation, you can pass them by posting it while invoking Jenkins build request with http://YOURHOST/jenkins/job/PROJECTNAME/buildWithParameters.
Solution 3 - Jenkins
Aha, I found it in the documentation. So simple:
http://YOURHOST/jenkins/job/PROJECTNAME/build
Solution 4 - Jenkins
I needed to add parameters and I wanted to do it over https. It took me a while but the following worked for me:
curl --request POST --url 'https://HOST_NAME/job/JOB_NAME/buildWithParameters?token=TOKEN' --header 'cache-control: no-cache' --header 'content-type: application/x-www-form-urlencoded' --data 'name1=value1&name2=value2'
Solution 5 - Jenkins
Use:
http://some server/job/myjob/buildWithParameters?token=TOKEN&PARAMETER=Value
You can take a look at this documentation: Parameterized Build
Solution 6 - Jenkins
curl -H POST http://USERNAME:PASSWORD@JENKINS_HOST:PORT/job/JOB_NAME/build?token=YOUR_TOKEN
Set YOUR_TOKEN at job configuration -> build triggers -> Trigger builds remotely.
Solution 7 - Jenkins
There is a good sample of using the above API from Python. The project is called Python Jenkins, and you may find it here: link
Solution 8 - Jenkins
Jenkins has a documented REST API. You can make your little web service invoke it.
Solution 9 - Jenkins
With curl if you have multiple arguments to pass like a token and a parameter you might have to quote on Linux shell:
curl -H POST "http://USERNAME:PASSWORD@JENKINS_HOST:PORT/job/JOB_NAME/build?token=YOUR_TOKEN&PARAMETER=VALUE"
Solution 10 - Jenkins
Install Generic Webhook Trigger plugin. Select generic webhook trigger in build trigger actions. Generate a random string and paste in token. Now your job can be triggered with a http request to the following url.
http://JENKINS_URL/generic-webhook-trigger/invoke?token=TOKEN_VALUE
replace your jenkins url and token value
