If you are using declarative pipeline and not the earlier DSL, you will need to disable the automatic Declarative Checkout SCM step. A continuous delivery (CD) pipeline is an automated expression of your process for getting software from version control right through to your users and customers. Docker can build images automatically by reading the instructions from a Dockerfile. In multibranch pipelines, it's not straight forward to tell the difference between tags, pull requests, and regular branch builds. Key give us access to out jenkins global variables. but i'll add as a placeholder for now. When Jenkins is in one project and the pipeline strategy build is in another project, the view log link in the OpenShift Container Platform web console points to the wrong URL because if cannot find the Jenkins service/route. branch - its the branch parameter which comes from the pipeline stage and we use stageParams to access that variable in the shared library. Then Jenkins runs on port 8080, and Artifactory runs on port 8081. Declarative Pipeline is a relatively recent addition to Jenkins Pipeline which presents a more simplified and opinionated syntax on top of the Pipeline sub-systems. My pipeline is declarative, not scripted, and I'm using Jenkins 2. 2 you can nest stages in the Declarative pipeline-- though it all needs to be in a "pipeline" block. Within the scripted pipeline it was vital to track currentBuild. In particular, such a variable will not be visible in other methods of the script. zip to nexus and pass on this artifact URL to further stages.
