[FIXED] How to invoke a jenkins pipeline A in another jenkins pipeline B in separate Jenkins master?

Issue

Important is separate Jenkins master. I expecting something like

script { build job: 'https://second_instance_jenkins.mycompany.com/jobs/alt_build_job', parameters: [] }

However this does not work, I cannot connect to other master server, neither I know how to properly AUTH using this syntax. There are tons of examples how to invoke another job within same Jenkins, but not at separate independent Jenkins master!

Thanks.

Solution

Found it. I have to use Parameterized-Remote-Trigger as described here

https://www.jenkins.io/doc/pipeline/steps/Parameterized-Remote-Trigger/

I also going to post my working pipeline step. I wish there are more examples in manual.

    steps {
        triggerRemoteJob auth: CredentialsAuth(credentials: '7f89634523-1b42-440d-8053-aa3d523523441d'), 
            enhancedLogging: true, 
            job: 'Build/my-integration', 
            remoteJenkinsUrl: 'https://second_instance_jenkins.mycompany.com/', 
            useCrumbCache: true,
            httpGetReadTimeout: 600,
            httpPostReadTimeout: 600,
            useJobInfoCache: true,
            parameters: '''
                PROJECT_NAME=core
                BUILD_TYPE=Debug
                PLATFORM=Linux
                '''
        }
