Continuous Delivery with Docker and Jenkins

Use shared library in Jenkinsfile

Finally, we can use the shared library in the Jenkinsfile script.

Let's have a look at the example:

pipeline {   agent any   stages {       stage("Hello stage") {           steps {           sayHello 'Rafal'         }       }   }}

If "Load implicitly" hadn't been checked in the Jenkins configuration, then we would need to add "@Library('example') _" at the beginning of the Jenkinsfile script.

As you can see, we can use the Groovy code as a pipeline step sayHello. Obviously, after the pipeline build completes, in the console output, we should see Hello Rafal!.

Shared libraries are not limited to one step. Actually, with the power of the Groovy language, they can even act as templates for entire Jenkins pipelines.
