We need to create a GitHub hook in such a way that, if anyone merges the branch create pull request and merge itthen it should trigger the Jenkins job.

We do not use multibranch pipeline, we use just pipeline jobs i. Then i have enabled scm polling in Jenkins job for that particular job. But, the issue is the job is getting triggered for a commit to the xyz branch and also if we merge the pull request.

But, the expected behavior is, the job should be triggered only for the merge. The action that was performed. Now what token should i give there? I am very new to github please help. But here it will scan the repository in jenkins. So if you can search how to trigger specific jenkins job will be great help. I don't know if you still need help but at least the next person to look on this page might benefit. I have just managed to do this.

So I literally just set up the branch I wanted to trigger a Jenkins build with the 'Just push the event' option and the gitscm option on Jenkins like you normally set up auto-build for a push event. Turns out it works when a PR is merged into the branch in question without any additional settings. Hope this helps. Turn on suggestions.

The issue is that my jenkins build itself will make create a tag for the release candidate and pushes it to bitbucket.

Is there a way to limit the trigger to a specific branch? For example the webhook triggers on a push to master but not when a tag is pushed. Is there no way for you to change your build such that it only pushes a tag to Bitbucket for a specific branch?

The webhook from Bitbucket has to include the name of the branch. I'm no PM, but I would imagine that one has more flexibility to write scripts how they please on the Jenkins side and hence perhaps the challenge of filtering branches is better tackled there. You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in. I'm not sure what you mean by pushing a tag for a specific branch.

In Git tags are objects like commits and branches. Pushing can involve any of them. Once the call to the API is made, it will trigger a build.

I'll continue looking for a way to prevent Jenkins from building on trigger if the desired branch has not changed. I totally didn't phrase that right. What I'm getting at is that when Jenkins starts a build after being triggered by a BB webhookit must run some script that you wrote that then does the tagging and pushing.

From what I understand, the problem you're facing is that push from the build triggers yet another webhook etc. But I suspect that you can break the loop from your own script using some sort of pre-condition that must be satisfied before your script decides to tag the release candidate and push the tag.

Does you build script have access to the payload of the webhook?

If so, the payload contains what was pushed. You should be able to then notice that the push only contained a tag and that the name of the tag matched the pattern you must use for your release candidates.

Based on that pre-condition, you could choose to not tag again and push the tag. There does not seem to be an answer because I have looked for the same information but never found a solution.

From the documentation it is not clear how do you use Generic Webhook plugin in combination with Multibranch pipeline, and in scripted pipeline there is reference variable is used, but declarative has ref defined not clear is that variable has some affect on which branch build to perform execution.

The naming of ref and reference is just names of a variable. I'll change it to same name to avoid confusion. You may try changing your Jenkinsfile to this in all branches :. Now I can see more jobs identified with the same request:.

Thanks again tomasbjerre. Still it should be, other way around:. Hey tomasbjerreI have kind of related question to that, since it's still not closed issue, I hope you wouldn't mind if I address it here.

So everything above is working ok, but I have an issue when I am trying now to do the same with Pull Requests, I have "Suppress automatic SCM triggering" option enabled within the multi-branch pipeline, so it's not get triggered whenever new PR is opened within the github repo, but on my request using generic-webhook-trigger-pluginbut still creating job id's by indexing the repo.

And it seems, it could not identify those jobs until they're not run at least once, but that's not good for the fresh PR's, since they will be never triggered. So I wonder, if I'm missing something again, or I always should do some kind of "fake" run within my pipeline, so generic-webhook-trigger-plugin can index such type of jobs afterwards? Im not sire exactly what you are doing and if it is possible.

I configure this plugin with job dsl and the pipeline is just using whatever values i resolve. I usually create one pr pipeline per repo or just one global for any repo. Oh wow, thanks for the fast reply! Ok, I'll try to explain on more simple example. Also, as to your example you've given - when you create a new item jobare you able to trigger it with the generic-webhook-trigger-pluginright after? So, let's skip the multibranch pipeline. I've just created simple pipeline job, with the same pipeline we discussed above, from the very beginning, to make it simple.

And at this point, it's never launched:. But after I execute job once, manually, and trigger it with the same request again, I get it listed:. So it seems, it should be indexing pipeline, at least once, before it gets visible for generic-webhook-trigger-plugin?

Yes that is my understanding. You are creating a pipeline that configures properties of the job.Single-tenant, high-availability Kubernetes clusters in the public cloud.

Fast and secure way to containerize and deploy enterprise workloads in Kubernetes clusters. Build, deploy and manage your applications across cloud- and on-premise infrastructure. Back to blog. March 25, by Graham Dumpleton. In contrast to OpenShift 2 where one would use git to push up the code for your application into OpenShift, with that triggering a new build and deployment, OpenShift 3 will instead pull your code from your source code repository.

This difference means that under OpenShift 3, pushing changes up to your code repository will not by default automatically trigger a new build and deployment. To enable automatic builds when code changes are pushed up to your code repository, it is necessary to link your source code repository and OpenShift using a webhook integration.

If you were for example using GitHub to host the code repository for your application, you would configure GitHub to trigger a GitHub webhook on a push, where the target URL is a special URL exposed by the OpenShift cluster where your application is hosted.

That way when a push is performed, OpenShift will be notified by GitHub and a new build triggered automatically. Veer Muchandi has demonstrated how to do this previously in a video on this blog and further information can be found in our documentation about using the GitHub webhook mechanism.

What though if you didn't want to trigger a new build immediately after code was pushed to GitHub and instead you wished to have the code passed through a service such as Travis-CI which would run code tests first.

For this case you would need to use a Generic webhook. In this blog post I am going to walk you through setting up this scenario using a webhook proxy service to mediate between Travis-CI and OpenShift.

A webhook in web development is a method of augmenting or altering the behaviour of a web application, through the use of custom callbacks.

The idea behind a webhook is that when you update some resource on a web site or via a web service, it can trigger some further action by initiating a HTTP request against a special URL of yet another web service. Great in concept, but one downside of webhooks are that their uses are so varied that it is hard to develop standards as to what information may be carried by the URL for the request, in request headers, or the payload of the request itself.

What tends to happen is that the producers of the webhook callback, define their own specification as to the data they will send. If you as a consumer want to allow for maximum interoperability, you have two choices. You either try and support all the different formats for webhook producers you may want to interoperate with, or you define your own format for what you expect and then rely on others to use that format or create a webhook proxy which translates callbacks from one format to another.

In the case of OpenShift it takes the middle ground. It provides builtin support for the most popular webhook producers it would need to deal with, such as GitHub, accepting the GitHub webhook format, but also defines its own format for a Generic webhook. If you are not familiar with Travis-CIit is a continuous integration service used to build and test software projects hosted at GitHub.

It is especially popular due to its free tier offering for projects which are released as Open Source. Whether you are running a web site related to an Open Source project, or are a commercial organisation using its paid service, you may wish to use it to run tests on your application code and only deploy the updated code if it passes all your tests.Build, deploy and manage your applications across cloud- and on-premise infrastructure.

Toggle nav. When defining a BuildConfigyou can define triggers to control the circumstances in which the BuildConfig should be run. The following build triggers are available:. OpenShift Container Platform webhooks currently only support their analogous versions of the push event for each of the Git based source code management systems SCMs. All other event types are ignored. When the push events are processed, a confirmation is made as to whether the branch reference inside the event matches the branch reference in the corresponding BuildConfig.

If they match, then the exact commit reference noted in the webhook event is checked out for the OpenShift Container Platform build. If they do not match, no build is triggered. For all webhooks, you must define a Secret with a key named WebHookSecretKey and the value being the value to be supplied when invoking the webhook. The webhook definition must then reference the secret. The secret ensures the uniqueness of the URL, preventing others from triggering the build. The value of the key will be compared to the secret provided during the webhook invocation.

The secret is then defined as follows. Note that the value of the secret is base64 encoded as is required for any data field of a Secret object. GitHub webhooks handle the call made by GitHub when a repository is updated.

When defining the trigger, you must specify a secretwhich will be part of the URL you supply to GitHub when configuring the webhook. The secret used in the webhook trigger configuration is not the same as secret field you encounter when configuring webhook in GitHub UI.

The former is to make the webhook URL unique and hard to predict, the latter is an optional string field used to create HMAC hex digest of the body, which is sent as an X-Hub-Signature header. Now, whenever you push a change to your GitHub repository, a new build will automatically start, and upon a successful build a new deployment will start.

Gogs supports the same webhook payload format as GitHub. Therefore, if you are using a Gogs server, you can define a GitHub webhook trigger on your BuildConfig and trigger it via your Gogs server also. Given a file containing a valid JSON payload, such as payload. The -k argument is only necessary if your API server does not have a properly signed certificate. GitLab webhooks handle the call made by GitLab when a repository is updated.

As with the GitHub triggers, you must specify a secret. Bitbucket webhooks handle the call made by Bitbucket when a repository is updated. Similar to the previous triggers, you must specify a secret.You can configure your workflows to run when specific activity on GitHub happens, at a scheduled time, or when an event outside of GitHub occurs.

For more information, see " GitHub's products. You can configure your workflow to run when webhook events are created from activity on GitHub.

Workflows can use more than one webhook event to trigger a workflow run. For more information, see " Webhooks " in the GitHub Developer documentation. For more information about the on syntax, see " Workflow syntax for GitHub Actions.

An event occurs on your repository, and the resulting event webhook has an associated commit SHA and Git ref. The workflow files must be present in that commit SHA or Git ref to be considered. For example, if the event occurred on a particular repository branch, then the workflow files must be present in the repository on that branch. The workflow files for that commit SHA and Git ref are inspected, and a new workflow run is triggered for any workflows that have on: values that match the triggering event.

The workflow runs on your repository's code at the same commit SHA and Git ref that triggered the event. For more information, see " Using environment variables. For more information, see " Triggering new workflows using a personal access token. If you need to specify activity types or configuration for an event, you must configure each event separately.

You must append a colon : to all events, including events without configuration. You can configure your workflow to run when webhook events are created on GitHub.

Some events have more than one activity type that triggers the event. If more than one activity type triggers the event, you can specify which activity types will trigger the workflow to run. More than one activity type triggers this event. Note: This event will only trigger a workflow run if the workflow file is on the master or default branch.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Sign in to your account. Is it possible to configure the webhook to be triggered if there is a change to a specific branch? For example, I would like to trigger a jenkins job only if there is a push to a branch called "release". There is not support for this at this time. The easiest setup here would be to configure your Jenkins job to build for only certain branches.

If this isn't a potential solution for you, let me know, as I'd like to understand more of your use case. I'd prefer to keep that logic in Jenkins, as it's already there and can cause confusion for others as configuration is then occurring in two different systems. So when a change to a branch, say "xyz" triggers the jenkins job, jenkins builds "release" branch again as it sees a commit in "release" which was just a release number change which I don't want to build.

So because we want the version number of our pom pushed back to "release" just relying on jenkins to build "release" is not sufficient. We need to stop the webhook from firing if the change is not pushed to a pre-configured branch name. I'm kinda wondering how that isn't causing an infinite loop there. Infinite loop is prevented as we always commit back the version update in pom from a specific user and use the feature in the webhook to ignore specific users. I think this feature was introduced in v2 of webhook.

So that works and we don't get into an infinite loop. Makes sense. I'll go ahead and add this to the to-do list. I wouldn't expect it to last very long, but may be a few days. For you right now, would you prefer to whitelist or blacklist branches to trigger? Figured I'd start with one and go from there. On 18 MaratMichael Irwin notifications github.

No worries. I was hoping to get it done thus past weekend but got hit with bronchitis, which just knocked me out for a few days. Can we shoot for Wednesday? That work for you? You up for trying out a snapshot version? If so, I have it linked below. Go into your plugin management, uninstall the old version, then upload the jar.

Don't worry After installation, you should see the new branch options in the Advanced Configuration section. I was able to plug in both whitelist and blacklist functionalities. If you could try out your use case, I'd be happy to hear if labeling makes sense, it's easy to use, etc. Any feedback at all would be greatly appreciated. Thanks a ton. I should be able to get this tried tomorrow. I am not the stash admin at our company, but I should be able to speak to the right person and get this tested.

I shall get back to you.
