Options directive (timeout, retry) in Jenkins - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the timeout option do in a Jenkins pipeline?

The timeout option stops the pipeline if it runs longer than the specified time. This helps avoid stuck or slow builds.

beginner

How does the retry option help in Jenkins pipelines?

The retry option tries to run a block of steps again if they fail, up to a set number of times. It helps handle temporary errors.

Show a simple Jenkins pipeline snippet using timeout and retry options.

pipeline { options { timeout(time: 10, unit: 'MINUTES') } stages { stage('Build') { steps { retry(3) { echo 'Building...' } } } } }

beginner

What happens if a Jenkins pipeline step exceeds the timeout duration?

Jenkins stops the pipeline and marks it as failed. This prevents wasting resources on stuck or very slow builds.

intermediate

Can the retry option be used inside a specific stage or only globally in Jenkins pipelines?

The retry option can be used inside specific stages or steps to retry only that part, or globally to retry the whole pipeline block.

What does the Jenkins timeout option control?

A Number of times to retry a failed step

B Maximum time a pipeline or stage can run before stopping

C The delay between pipeline runs

D The number of parallel builds allowed

The timeout option sets the maximum allowed time for a pipeline or stage to run before Jenkins stops it.

How many times will Jenkins retry a step if retry(3) is set and the step keeps failing?

A 4 times

B 2 times

C 1 time

D 3 times

The retry(3) option means Jenkins will try the step up to 3 times if it fails.

Where can the timeout option be placed in a Jenkins pipeline?

A Only inside stages

B Only inside steps

C Inside the options block at pipeline or stage level

D Only in the Jenkins global configuration

The timeout option is used inside the options block, which can be at the pipeline or stage level.

What happens if a step fails but no retry option is set?

A The pipeline fails immediately

B The pipeline pauses for manual input

C Jenkins retries automatically once

D The pipeline ignores the failure

Without retry, a failed step causes the pipeline to fail immediately.

Which unit can be used with the Jenkins timeout option?

A All of the above

B MINUTES

C HOURS

D SECONDS

Jenkins timeout supports units like SECONDS, MINUTES, and HOURS.

Explain how the timeout and retry options improve Jenkins pipeline reliability.

Think about how these options prevent failures and delays.

Describe where and how to use the timeout and retry options in a Jenkins pipeline script.

Consider the syntax and placement in the Jenkinsfile.
