Excluding Draft PRs from Jenkins - jenkins

I will like to be able to choose to only run Jenkins build on PRs who are not marked as draft. Is there currently a way to do that?
I found something like this: https://github.com/jenkinsci/github-branch-source-plugin/pull/416, but cannot seem to find any place in the Jenkins dashboard that will allow me to exclude draft PRs.
Thanks!

The GitHub API allows you to view details of a PR and see if the PR is a draft:
Request:
curl \
-H "Accept: application/vnd.github+json" \
-H "Authorization: token <TOKEN>" \
https://api.github.com/repos/OWNER/REPO/pulls/PULL_NUMBER
Response:
{
"url": "https://api.github.com/repos/octocat/Hello-World/pulls/1347",
"id": 1,
"node_id": "MDExOlB1bGxSZXF1ZXN0MQ==",
...
"auto_merge": null,
"draft": false, <---- This is what you want
"merged": false,
...
"deletions": 3,
"changed_files": 5
}
You will have to modify the Jenkins job itself to perform this API call, parse the response and get the value of draft, and continue or abort the build depending on the value.

Creating / Getting a Cloud Run Job using the Python API Client Library

I created a Cloud Run Job using command line:
gcloud --verbosity=debug beta run jobs create my-job \
--image=us-docker.pkg.dev/cloudrun/container/job:latest
When I can list the jobs using the API Client library, my-job is returned:
import googleapiclient.discovery
with googleapiclient.discovery.build('run', 'v1') as client:
request = client.namespaces().jobs().list(parent=f'namespaces/my-project')
response = request.execute()
print(response)
However, when I try to get the job using the following snippet, I get 404 "Requested entity was not found":
...
request = client.namespaces().jobs().get(name='namespaces/my-project/jobs/my-job')
response = request.execute()
...
I am also unable to create a job using the following snippet, this again return 404 "Requested entity was not found":
request = client.namespaces().jobs().create(parent=f'namespaces/my-project',
body={
"metadata": {
"name": "my-job2",
},
"spec": {
"template": {
"spec": {
"template": {
"spec": {
"containers": [{
"image": "us-docker.pkg.dev/cloudrun/container/job:latest"
}],
}
}
}
}
},
})
I have Cloud Run Admin permissions for the project.
What am I missing?
Looking into the API reference, it appears you are using the call correctly 1, 2. When doing the get call, you need to specify the correct regional endpoint. So, it might happen that you are using the global endpoint for the list, create and get calls. However, make sure that you use the regional endpoint for the get and create call.
The global endpoint has this documentation for v14: "For v1, this endpoint only supports Global List: use regional endpoints instead."
You can see an example using this command from cloud shell. (This assumes your region is 'us-central1', if not that needs to be updated).
curl -X GET
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token)
https://us-central1-run.googleapis.com/apis/run.googleapis.com/v1/namespaces/my-project/jobs/my-job
curl -X GET
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token)
https://run.googleapis.com/apis/run.googleapis.com/v1/namespaces/my-project/jobs/my-job

Resource not found - Triggering BitBucket Pipeline using curl

I created a new project and added a repository to it in my workspace. Further, I added a bitbucket-pipelines.yml to build a pipeline. I am able to trigger the pipeline manually however while trying to execute it using BitBucket API using curl, I get the below error every time:
Can anyone suggest what I am missing here?
NOTE: The same curl command (below) is able to run other pipelines in different repositories in the same workspace, so do I need to enable something in my current repository to access pipeline using BitBucket APIs. TIA
Error:
{"type": "error", "error": {"message": "Resource not found"}}%
cURL command:
curl -X POST -is -u username:password \
-H 'Content-Type: application/json' \
https://api.bitbucket.org/2.0/repositories/workspace-name/repo-name/pipelines/ \
-d '
{
"target": {
"type": "pipeline_ref_target",
"ref_type": "branch",
"ref_name": "master",
"selector": {
"type": "custom",
"pattern": "create-tenant"
}
}}'
So the tokens I was using in the curl weren't added to Repository Settings -> User and group access. Got them added and was able to execute it successfully.

Unable to get the payload from GitHub web hook trigger in jenkins pipeline

I have configured a Github web hook with the below settings:
Payload URL: https:///github-webhook/
Content Type: application/x-www-form-urlencoded
Events : Pushes, Pull Requests
The Jenkins job that I have, is a pipeline job that has the below enabled:
Build Trigger: GitHub hook trigger for GITScm polling
With the above configuration, I see that in response to an event ie; push/PR in GitHub, the jenkins job gets triggered successfully. In GitHub, under Recent Deliveries for the web hook, I see the details of the payload and a successful Response of 200.
I am trying to get the payload in Jenkins Pipeline for further processing. I need some details eg: PR URL/PR number, refs type, branch name etc for conditional processing in the Jenkins Pipeline.
I tried accessing the "payload" variable (as mentioned in other stack overflow posts and the documentations available around) and printing it as part of the pipeline, but I have had no luck yet.
So my question is, How can I get the payload from GitHub web hook trigger in my Jenkins Pipeline ?
You need to select Content type: application/json in your webhook in GitHub. Then you would be able to access any variable from the payload GitHub sends as follows: $. pull_request.url for pr url, for example.
Unsure if this is possible.
With the GitHub plugin we use (Pipeline Github), PR number is stored in the variable CHANGE_ID.
PR URL is pretty easy to generate given the PR number. Branch name is stored in the variable BRANCH_NAME. In case of pull requests, the global variable pullRequest is populated with lots of data.
Missing information can be obtained from Github by using their API. Here's an example of checking if PR is "behind", you can modify that to your specific requirements:
def checkPrIsNotBehind(String repo) {
withCredentials([usernamePassword(credentialsId: "<...>",
passwordVariable: 'TOKEN',
usernameVariable: 'USER')]) {
def headers = ' -H "Content-Type: application/json" -H "Authorization: token $TOKEN" '
def url = "https://api.github.com/repos/<...>/<...>/pulls/${env.CHANGE_ID}"
def head_sha = sh (label: "Check PR head SHA",
returnStdout: true,
script: "curl -s ${url} ${headers} | jq -r .head.sha").trim().toUpperCase()
println "PR head sha is ${head_sha}"
headers = ' -H "Accept: application/vnd.github.v3+json" -H "Authorization: token $TOKEN" '
url = "https://api.github.com/repos/<...>/${repo}/compare/${pullRequest.base}...${head_sha}"
def behind_by = sh (label: "Check PR commits behind",
returnStdout: true,
script: "curl -s ${url} ${headers} | jq -r .behind_by").trim().toUpperCase()
if (behind_by != '0') {
currentBuild.result = "ABORTED"
currentBuild.displayName = "#${env.BUILD_NUMBER}-Out of date"
error("The head ref is out of date. Please update your branch.")
}
}
}

Jenkins Webhook Header as Argument to Shell script

I'm trying to trigger a Jenkins job through the webhook using the curl command whenever there is EC2 Spot Instance Interruption Warning with below sample event. All this will be done in AWS lambda from CloudWatch Event Trigger.
{
"version": "0",
"id": "1e5527d7-bb36-4607-3370-4164db56a40e",
"detail-type": "EC2 Spot Instance Interruption Warning",
"source": "aws.ec2",
"account": "123456789012",
"time": "1970-01-01T00:00:00Z",
"region": "us-east-1",
"resources": [
"arn:aws:ec2:us-east-1b:instance/i-0b662ef9931388ba0"
],
"detail": {
"instance-id": "i-0b662ef9931388ba0",
"instance-action": "terminate"
}
}
My aim is to get the instance-id from the event and pass it as a header to the jenkins webhook where the jenkins job gets triggered and this header has to be sent as an argument to the underlying python script in the jenkins job.
I tried the below approach which didn't give me success. And am not sure if this is how it is done. :)
curl -H 'param: instance' https://jenkins.url/generic-webhook-trigger/invoke\?token\=jenkins-job
Generic Jenkins webhook trigger is configured as below.
The final python script in the job is configured as below.
python maintenance.py $.param
I'm trying to get the final script similar to below. Please let me know if you know of any approach how can I get this done. TIA
python maintenance.py i-0b662ef9931388ba
I fixed this by adding the following.
Add string parameter under This project is parameterized as shown below.
Next under Generic Webhook Trigger I have added Header parameters
Now, we can directly pass this param in the build command using $param.
The curl command is now modified to below.
curl --location --request POST 'https://jenkins.url/generic-webhook-trigger/invoke\?token\=jenkins-job' --header 'Content-Type: application/json' --header "param: $EVENT_DATA" --data-raw ''
What did I learn from this?
I was too lazy to read the documentation and finally figured it out only after reading it.

How to post a custom comment back to a Github PR from jenkins build

I am basically looking at how i can post a comment to a GitHub PR using jenkins multibranch pipeline job. Everything works for me and PRs are triggered and any commit to the source branch also triggers the PR build for that branch. Also the variables are getting substituted just fine, but somehow the script fails while doing a post of the custom comment from the build. Here is my sample declarative Jenkinsfile.
def PULL_REQUEST = env.CHANGE_ID
pipeline {
agent {
label "pod-custom"
}
stages {
stage('Checkout') {
steps {
checkout scm
}
}
stage('Test Plan') {
steps {
withCredentials([string(credentialsId: 'github-api', variable: 'GITHUB_TOKEN')]) {
sh "curl -s -H \"Authorization: token ${GITHUB_TOKEN}\" -X POST -d '{\"body\": \"This is my first test comment from jenkins\",\"commit_id\": \"4d0f019b93c11f1fabc8313da4c461dbdbde1fd5\",\"path\": \"Jenkinsfile\",\"position\": 4}' \"https://github.***.com/api/v3/repos/***/${env.GIT_URL.tokenize("/")[-1].tokenize(".")[0]}/pulls/${PULL_REQUEST}/comments\""
}
}
}
}
}
Here is the error i see :-
Running shell script
+ curl -s -H 'Authorization: token ****' -X POST -d '{"body": "This is my first test comment from jenkins","commit_id": "4d0f019b93c11f1fabc8313da4c461dbdbde1fd5","path": "Jenkinsfile","position": 4}' https://github.***.com/api/v3/repos/***/***/pulls/4/comments
{
"message": "Validation Failed",
"errors": [
{
"resource": "PullRequestReviewComment",
"code": "invalid",
"field": "path"
}
],
"documentation_url": "https://developer.github.com/enterprise/2.14/v3/pulls/comments/#create-a-comment"
}
I am wondering what is the GitHub API looking for as far as this error is concerned. My use case is just that i need to be able to post a comment to the PR i am pulling in the build as you can see, and this comment should be a straight comment to the PR and not the issue in GitHub.
Any help/suggestions here will be greatly appreciated as always.
i was able to figure this out by following the below post :-
Create comment on pull request. I think i wasn't quite understanding that github treats every PR as an issue while not vice-versa, and so what you could achieve by doing a POST /repos/:owner/:repo/issues/:number/comments, is exactly what i was looking here. I could test this just fine using the below :-
def PULL_REQUEST = env.CHANGE_ID
withCredentials([string(credentialsId: 'github-api', variable: 'GITHUB_TOKEN')]) {
sh "curl -s -H \"Authorization: token ${GITHUB_TOKEN}\" -X POST -d '{\"body\": \"This is my first test comment from jenkins\"}' \"https://github.***.com/api/v3/repos/***/${env.GIT_URL.tokenize("/")[-1].tokenize(".")[0]}/issues/${PULL_REQUEST}/comments\""
}
This posted the comment "This is my first test comment from jenkins" just fine under the PR conversation tab, which is what i needed.
