How do I trigger builds remotely?
I followed some tutorial and ready with this below:
Curl user `sanveen:585da82e7d3df2991dea3533ea794d06 `
The M link format is http://localhost:8080/jenkins/job/triggerbuild/build?token=gitbitsolution6789
The authentication token set in the jenkins-plugins section.
But where do I call this and trigger the build?
Let's suppose you have two machines A and B. On machine A Jenkins is configured. And your purpose is to trigger builds from machine B. In order to do that you configure Jenkins to allow builds using scripts. And make HTTP POST requests to machine A from machine B.
To send POST requests to machine B, you can make use of curl and create a Bash script to trigger a build.
For example,
curl -X POST http://API_TOKEN_USER_ID:API_TOKEN#your-jenkins.com/job/JobName/build?token=AUTHENTICATION_TOKEN

We're using BitBucket to host our Git repositories.
We have defined build jobs in a locally-hosted Jenkins server.
We are wondering whether we could use BitBucket pipelines to trigger builds in Jenkins, after pull request approvals, etc.
Triggering jobs in Jenkins, through its REST API is fairly straightforward.
1: curl --request POST --user $username:$api_token --head http://jenkins.mydomain/job/myjob/build
This returns a location response header. By doing a GET on that, we can obtain information about the queued item:
2: curl --user $username:$api_token http://jenkins.mydomain/queue/item/<item#>/api/json
This returns JSON describing the queued item, indicating whether the item is blocked, and why. If it's not, it includes the URL for the build. With that, we can check the status of the build, itself:
3: curl -–user $username:$api_token http://jenkins.mydomain/job/myjob/<build#>/api/json
This will return yet more json, indicating whether the job is currently building, and if it's completed, whether the build succeeded.
Now BitBucket pipeline steps run in Docker containers, and have to run on Linux. Our Jenkins build jobs run on a number of platforms, not all of which are Linux. But BitBucket shouldn't care. Making the necessary REST API calls can be done in Linux, as I am in the examples above.
But how do we script this?
Do we create a single step that runs a shell script that runs command #1, then repeatedly calls command #2 until the build is started, then repeatedly calls command #3 until the build is done?
Or do we create three steps, one for each? Do BitBucket pipelines provide for looping on steps? Calling a step, waiting for a bit, then calling it again until it succeeds?
I think you should either use Bitbucket pipeline or Jenkins pipeline. Using both will give you to many options and make the project more complex than it should be.
(I'm new to Jenkins and curl, so please forgive any imprecision below.)
I am running a Jenkins job on one network that sends a curl command to a second network that is used to start a Jenkins job on that second network.
Sometimes I have to log onto that second network and restart the job using the Rebuild button provided by the Rebuild plugin.
I need to know how to determine whether the job on the second network was started by the original curl command or restarted via the Rebuild plugin, without the user having to do anything but restart the job with the same parameters.
I could use an extra boolean-parameter in the job on the second network that can be set to true by the curl command and to false when using the Rebuild button, but that requires the user to manually change the value of that parameter. I don't want the user to have to do that.
I think this only possible by using different users, or lets say an own user for the remote invocation. Anything more informative would have to be done manually for instance by an own paramter for the job. Normally jobs are started by developers, schedulers, hooks or by other jobs on the same instance. If triggered remotelly the job is triggered by a user as well, without authentication its the anonymus user who triggers the job.
Do you know the Jenkins CLI, could replace your curl commands?

I would like to access variables from the Jenkins job console output on a different server using REST API.
How can I archive this.
Jenkins job runs on server A and I would like to read or get all variables on Server B. There is no connection between server A and server B.
There is no connection between server A and server B.
Hopefully, there is enough a connection to allow a curl.
That would allow to curl a property file that server A job would have generated, in order to write the variables (and for the curl to fetch them)
See this solution as an example, using the publisher artifact method of the Jenkins Job DSL API.
You can do it with the API of the EnvInject plugin with:
curl <jenkins-host>/job/<job_name>/<buildNumber>/injectedEnvVars/export

I'd like to configure bitbutcket to trigger a jenkins build.
I've spent some time researching this and all the answers are from a few years ago, and have not found any guides because things seem to have changed since.
What I'm trying to do:
A bitbucket push to a particular branch triggers a build.
What I've got:
Bitbucket web hooks which fires HTTP request to Jenkins on a push to any branch. I've also installed the Bitbucket plugin on Jenkins which adds a check box in the job config Build when a change is pushed to BitBucket. This checkbox doesnt seem to work (maybe I set it up wrong? minimal docs for this), despite me pushing to the configured branch in the SCM section.
Problem 1: Bitbucket does not fire a GET, but another request which causes a 403. I tested with postman, and it works with a GET, but not a POST.
Problem 2: This HTTP build request is fired on pushes to any branch. While the build is still restricted to a particular branch, it seems unnecessary to be rebuilding all the time.
How do i address these issues? Bitbucket does not seem to be very flexible in customizing this. The Jenkins plugin for bitbucket has a lot of 'bad' reviews. How are developers currently doing this?
SPECIFIC solution for Jenkins CI server--Webhook to Jenkins for Bitbucket plugin has been commercialized in latest version of Bit-Bucket and the current price is around $4800 which was earlier a free offering, because of this, guys who want to save their bucks, can go to the alternative solution by using webhooks feature of bit-bucket:-
Steps to create a webhook:-
BitBucket Side
1) Go to your bitbucket repo, click on Repository Setting, under WORKFLOW got for WEBHOOKS option and create a webhook.
a) creation of webhook:- URL https://JenkinsserverURL/git/notifyCommit?url=https://bitbucket.repository-link/repository.git
b) In the name tab, give any name of your choice
c) click on TEST CONNECTION before saving it. Make sure you get http status 200
d) View details your logs, check your request and response is correct.
Things to take care of from
Jenkins Side:-
1) Make sure repository mentioned in bitbucket webhook is used in Jenkins job.
2) In SCM option, activate/select Poll SCM option, don't mention anything in the schedule, leave it blank.
3) configure rest job,
Whenever your git repo observes any change an automatic build will get triggered in Jenkins. By default push trigger is activated and if you want to activate other action, please select those events while creating webhook.
***to specify the branch in repository webhook:-
http://yourserver/git/notifyCommit?url=<URL of the Git repository>[&branches=branch1[,branch2]*][&sha1=<commit ID>]
Cheers,
Is your Jenkins URL accessible from your bitbucket server? If yes that it should be fairly simple to do it. You add the webhook in your repository as http://<url-of-jenkins>/git/notifyCommit?url=<url-of-repository>. When jenkins receives this POST, it automatically triggers builds on those jobs that use this git repo with that URL you give in webhook.
But you also need to make sure your Build Schedule is set to empty for those jobs. otherwise it wont get triggered. You can specify a branch in webhook URL too
See the Push Notification from repository here
https://wiki.jenkins.io/display/JENKINS/Git+Plugin
For anyone here after July 2022, here are the simple steps I followed to make it work.
Create a live Jenkins URL
First, create a tunnel from a live URL to your local Jenkins URL using ngrok because using locahost:8080 directly as your webhook URL on bitbucket will simply not work as bitbucket does not recognize your local computer.
ps: ngrok claims to be the fastest way to put anything on the internet and I agree,
you can use it beyond Jenkins once you know the trick,
such as quickly handling out your localhost react app for testing by your friends
out of your local network
To do this is simple. For Linux:
Install ngrok snap install ngrok
Add authtoken ngrok config add-authtoken <token>
Don't have an auth token, sign up
Start a tunnel on your Jenkins port eg ngrok http 8080
To know more and for other OS, check ngrok download page
You will then get a response like
ngrok (Ctrl+C to quit)
Hello World! https://ngrok.com/next-generation
Session Status online
Account <your email>#<domain>.com (Plan: <plan type>)
Version 3.0.6
Region Europe (eu)
Latency 162ms
Web Interface <web interface url>
Forwarding https://<your-assigned-host>.ngrok.io -> http://localhost:8080
Basically, the web interface URL on click gives you a web interface to inspect all the requests being tunnelled from your ngrok live URL to your local host.
Forwarding URL is basically a proxy to your localhost, so when you want to configure webhook, instead of using locahost:8080, you replace it with ngrok URL eg https://syue-162-34-12-01.eu.ngrok.io and all requests get tunnelled to localhost:8080
Hook up the URL on bitbucket cloud
Secondly, configure your Bitbucket repository with a Webhook, using URL JENKINS_URL/bitbucket-hook/ (no need for credentials but do remember the trailing slash) eg https://syue-162-34-12-01.eu.ngrok.io/bitbucket-hook/
If you are using bitbucket server and not cloud or you want to know more, the bitbucket plugin documentation for Jenkins is pretty straightforward and easily understandable, see bitbucket plugin
then you can inspect all your webhook requests on the web interface URL or via your terminal as well as check your build logs on Jenkins via your localhost port or ngrok live url.
Disclaimer: I have not figured out how to enable build only when a specific branch change but you can configure jenkins to only build a specific branch or any branch created as your need may demand, check Source Code Management and Build Triggers
I have a repo in phabricator and cloned in my local machine.
Now I want to create a new Jenkins job automatically after creating a new repo in Phabricator. Jenkins API is available to create a new job remotely.
According to Jenkins:
To create a new job, post config.xml to this URL with query parameter name=JOBNAME. You need to send a Content-Type: application/xml header.
I can create a job by the following command using terminal.
curl -X POST -H "Content-Type:application/xml" -d "<project><builders/><publishers/><buildWrappers/></project>" "http://ip:port/createItem?name=AA_TEST_JOB1"
Question: How can I run the command by Harbormaster to create a Jenkins job and also send config.xml file for the configuration of that new job?
Guy Warner (http://www.guywarner.com/) has done a lot of work to show how this is possible. You can visit his blog post for more details: http://www.guywarner.com/2014/05/integrating-jenkins-and-phabricator.html (part 1) and http://www.guywarner.com/2014/06/part-2-integrating-phabricator-and.html (part 2).
The basic idea is that your Harbormaster Build Plan will make an HTTP request to your Jenkins instance.
We used his tutorials to setup almost 100 builds that trigger from Phabricator based on different types of changes.
Actually, there is no settings or automatic way to create a Jenkins job after creating a new repo in Phabricator.
I've solved this editing Phabricator php codes. Simple way is to call the Jenkins API from php codes after creating a repo.
