How to Login to Jenkins using commands and API?

Working commands for Login

# Method 1 - Login to Jenkins using CLI and Username and Password
$ java -jar jenkins-cli.jar -s http://13.235.81.87:8080/ -auth rajesh:1190c7e6cb8e3b65515f8495966814ad58 who-am-i
$ java -jar jenkins-cli.jar -s http://13.235.81.87:8080/ -auth rajesh:1190c7e6cb8e3b65515f8495966814ad58 delete-job test

##Command to know the status of Build?

$ curl http://myjenkins/job/myjob/lastBuild/api/json | grep --color result\":null
$ echo $?

##Trigger a Jenkins Job without authentication

$ wget http://yourserver/job/MyJobname/build?delay=0sec
$ wget -O - $HUDSON_URL/job/JOBNAME/build
$ curl http://jenkins:8080/job/my%20job/build

##Trigger a Jenkins Job with authentication

$ curl --user dbacher:$MY_API_TOKEN http://jenkins:8080/job/my%20job/build
$ curl --user <your_jenkins_username>:<your_jenkins_API_key>http://<jenkins_server_url>/job/<your_jenkins_job_name>/build

##Running commands against a secure Jenkins (basic auth or ssh keys)

$ java -jar jenkins-cli.jar -s http://myjenkins help --username me --password mypassword
$ java -jar jenkins-cli.jar -s http://myjenkins help -i ~/.ssh/id_rsa

##Triggering a job build against a secure Jenkins (avoiding a 1.5 year old open bug!)

$ java -jar jenkins-cli.jar -s http://myjenkins build 'My Awesome Jenkins Job' -i ~/.ssh/id_rsa
$ java -jar jenkins-cli.jar -s http://myjenkins build 'My Awesome Jenkins Job' -i ~/.ssh/id_rsa -s -v

##Passing parameters when triggering a job build

$ java -jar jenkins-cli.jar -s http://myjenkins build 'Deploy XYZ App' -i ~/.ssh/id_rsa -s -v -p target_env=api.cloudfoundry.com -p branch=master

How to get your_jenkins_API_key?

• Login to your Jenkins.
• Click on the username in the top right.
• Click on Configure.
• Click on ‘Show API Token’ button.
• You got it.
