Common Mistakes

Using 'Docker' with uppercase D instead of 'docker'.

Selecting a label that does not exist.

The label 'docker' selects agents that have Docker installed or are tagged accordingly.

💡 Hint

Common Mistakes

Using uppercase 'Windows' which does not match the label.

Using shorthand labels like 'win' that are not defined.

Labels are case-sensitive; 'windows' in lowercase matches the agent label correctly.

4fill in blank

hard

Fill both blanks to run the pipeline on an agent with label 'linux' and specify the stage name as 'Build'.

Jenkins

pipeline {
  agent { label '[1]' }
  stages {
    stage('[2]') {
      steps {
        echo 'Building project'
      }
    }
  }
}

💡 Hint

Common Mistakes

Mixing up stage names with labels.

Using incorrect labels like 'windows' for a Linux agent.

The agent label is 'linux' and the stage name is 'Build' as required.

5fill in blank

hard

Fill all three blanks to run the pipeline on an agent with label 'docker', name the stage 'Test', and print 'Running tests'.

Jenkins

pipeline {
  agent { label '[1]' }
  stages {
    stage('[2]') {

        echo '[3]'
