A Real-world CD Pipeline with Jenkins Workflow

Development Production

Jenkins Workflow

Pipeline as Code● Introduce “pipeline” as a new type in Jenkins● Codify an implicit series of stages into an explicit

.Jenkinsfile in your source repository● Resumability/durability of the pipeline state● Extend the DSL with your own steps

github.com/jenkinsci/pipeline-examples

Pipeline DSLnode('docker') { checkout scm

/* Grab the abbreviated SHA1 of our pipeline’s commit. */ sh 'git rev-parse HEAD > GIT_COMMIT' def shortCommit = readFile('GIT_COMMIT').take(6)

stage 'Build' def image = docker.build("jenkinsciinfra/bind:build-${shortCommit}")

stage 'Deploy' image.push()}
