How do you run pipeline stages in parallel in Jenkins?
⚡
Quick Answer
Wrap stages in a parallel block to execute them concurrently across agents.
Detailed Answer
parallel runs branches simultaneously — e.g. lint, unit tests, and integration tests at once — cutting total time. Each branch can target a different agent label. failFast: true aborts the rest if one branch fails.
Code Example
parallel {
stage('lint') { steps { sh 'make lint' } }
stage('test') { steps { sh 'make test' } }
}💡
Interview Tip
Mention failFast to abort on first failure.
