Continuous Delivery with Docker and Jenkins

Testing agents

No matter which agent configuration you chose, we should now check if it works correctly.

Let's go back to the hello world pipeline. Usually, the builds last longer than the hello-world example, so we can simulate it by adding sleeping to the pipeline script:

pipeline {     agent any     stages {          stage("Hello") {               steps {                    sleep 300 // 5 minutes                    echo 'Hello World'               }          }     }}

After clicking on Build Now and going to the Jenkins main page, we should see that the build is executed on an agent. Now, if we click on build many times, then different agents should be executing different builds (as shown in the following screenshot):
