Jenkins: How do I lint Jenkins pipelines from the command line?

Question

I would like to be able to perform linting on Jenkins pipelines and it seems that Groovy linting is not enough.

How can I do this?

Answer 1

HTTP without crumb.

If you want to use HTTP and don't want to use CRUMB. just add your username and password using the '-u' parameter. Replace <username> and <password> with the username and password of your user. Also Check that the url of the jenkins server is correct.

 curl --user <username>:<password> -X POST -F "jenkinsfile=<Jenkinsfile" http://localhost:8080/pipeline-model-converter/validate

Answer 2

Looks like there are two options for linting pipeline scripts, one via the cli on the leader or an http POST call:

Linting via the CLI with SSH

# ssh (Jenkins CLI)
# JENKINS_SSHD_PORT=[sshd port on master]
# JENKINS_HOSTNAME=[Jenkins master hostname]
ssh -p $JENKINS_SSHD_PORT $JENKINS_HOSTNAME declarative-linter < Jenkinsfile

Linting via HTTP POST using curl

# curl (REST API)
# Assuming "anonymous read access" has been enabled on your Jenkins instance.
# JENKINS_URL=[root URL of Jenkins master]
# JENKINS_CRUMB is needed if your Jenkins master has CRSF protection enabled as it should
JENKINS_CRUMB=`curl "$JENKINS_URL/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,\":\",//crumb)"`
curl -X POST -H $JENKINS_CRUMB -F "jenkinsfile=<Jenkinsfile" $JENKINS_URL/pipeline-model-converter/validate
