GitHub and Jenkins Pull Request Check - github

I have a question regarding GitHub checks for Pull Request. I have an integration between GitHub and Jenkins, which each time a Pull Request is opened it will trigger a Jenkins jobs to run. But how do I configure it so that if the Jenkins job is successful, it will pass back a Check validation back to GitHub Pull Request as a success as shown in below image?
I created a GitHub App and the Jenkins job is able to trigger during Pull Request, but no status is pass back. I think I am missing a step somewhere, but not sure which.

Showing ConcourseCI build status on github pull requests

I currently have a fully functioning pipeline that's been deployed to a concourse server. It will receive push events from a github repo, and run the pipeline as such.
I have a webhook that's also able to talk from github to the concourseCI server.
It looks something like this:
https://concourse.myorganization.app/api/v1/teams/my_team/pipelines/git-repo-name/resources/git-repo-pull-requests/check/webhook?webhook_token=some_token
I have it dropped into the settings of the Github repo as a webhook, and it's returning 2xx after each push to a pull request. How can I get the status of the build in ConcourseCI to show up on the pull request like this
GitHub build status is independent from the webhook: the webhook goes from GitHub to Concourse, while here we need the opposite direction: from Concourse to GitHub. Also, it cannot be synchronous, since the webhook triggers a build that takes time to complete.
You need to signal the build status with a Concourse resource. The one I prefer (since I wrote it :-) is https://github.com/Pix4D/cogito.

Triggering Jenkins Multibranch Pipeline automatically if a PR is raised on GitHub

I am using Jenkins Multibranch pipeline.
I've configured the APIs (github-webhook and ghprbhook) on GitHub.
Currently, If I click on "Scan Repository Now/Scan Repository Log" in Jenkins, the Jenkins will go through the GitHub and creates a new PR job in Jenkins if there are any PR on GitHub.
So I need to trigger this Multibranch pipeline whenever there is a Pull Request raised on GitHub. I want this pipeline to trigger automatically when there is a PR on GitHub.
What do I need to do to achieve this approach?
Is it possible to trigger Multibranch pipeline automatically whenever a PR is raised on GitHub?
To achieve this, I have selected only "Push and Pull Request" under "Let me select individual events" section of GitHub Webhooks.
PS: The GitHub branches are automatically detected in Jenkins.
Du you use the GitHub pull request builder plugin?
This Jenkins plugin builds pull requests from GitHub and will report the results directly to the pull request via the GitHub Commit Status API
When a new pull request is opened in the project and the author of the pull request isn't whitelisted, builder will ask Can one of the admins verify this patch?. One of the admins can comment ok to test to accept this pull request for testing, test this please for one time test run and add to whitelist to add the author to the whitelist.
If an author of a pull request is whitelisted, adding a new pull request or new commit to an existing pull request will start a new build.
A new build can also be started with a comment: retest this please.

Showing Jenkins pipeline status against pull requests in GitHub

I have recently started using Jenkins Pipelines and have a multibranch job configured which is happily picking up Jenkinsfile on one of my branches.
I have seen in screenshots on posts\articles that Jenkins can report back to pull requests in GitHub the status of whether the branch has passed\failed checks performed in the pipeline.
I am not seeing any such feedback for my pull request I have opened, I can see in Jenkins it has triggered a pipeline build which has passed.
How can I get the notification to show the pipeline checks have passed in GitHub. Do I need to configure something else?
I found out this was simply down to me using the Git instead of GitHub sources option when configuring the multibranch pipeline job in Jenkins.
The docs for the GitHub Branch Source plugin gave me the clues!
I now get status messages on my pull requests showing whether pipeline checks are pending\failed\passed.
Check out the Github Pull Request Builder Plugin, it should do what you require: https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin

Setup rules/alerts before raising a PR in Github

Basically whenever somebody raises a PR on my repository, I want to ensure that the person raising the PR has performed some actions (running a script etc.)
So is there a way to set up some rule or some alert so as to remind the person to perform that action before raising the PR.
You should use something called integration. Here you can see the GitHub Integrations Directory.
My favorite is Travis CI–you set it up using a .travis.yml file and then after the commits are pushed the tests are run and Travis sends the status response which will be visible to in the Pull request.
However, this can't stop the user to submit the pull request.
Like I mentioned, you cannot stop the user to open pull requests but you can tell him/her the steps how to contribute using the CONTRIBUTING.md in your project. Then when somebody opens a pull request or issue will see this alert:
