如何在这些构建步骤中使用 Jenkinsfile？

Question

I'm learning how to use Jenkins and working on configuring a Jenkins file instead of the build using the Jenkins UI.

The source code management step for building from Bitbucket:

The build step for building a Docker container:

The build is of type multi configuration project:

Reading the Jenkins file documentation athttps://www.jenkins.io/doc/book/pipeline/jenkinsfile/index.html and creating a new build using Pipeline :

I'm unsure how to configure the steps I've configured via the UI: Source Code Management & Build . How to convert the config for Docker and Bitbucket that can be used with a Jenkinsfile?

The SCM will not be changed, regardless if you are using UI configuration or a pipeline, although in theory you can do the git clone from the steps in the pipeline, if you really insist convert the SCM steps in pure pipeline steps.

The pipeline will can have multiple stages, and each of the stages can have different execution environment. You can use the Docker pipeline plug-in , or you can use plain sh to issue the docker commands on the build agent.

Here is small sample from one of my manual build pipelines:

pipeline {
    agent none
    stages {
        stage('Init') {
            agent { label 'docker-x86' }
            steps {
                checkout scm
                sh 'docker stop demo-001c || true'
                sh 'docker rm demo-001c || true'
            }
        }
        stage('Build Back-end') {
            agent { label 'docker-x86' }
            steps {
                sh 'docker build -t demo-001:latest ./docker'
            }
        }
        stage('Test') {
            agent {
                docker { 
                    label 'docker-x86' 
                }
            }
            steps {
                sh 'docker run --name demo-001c demo-001:latest'
                sh 'cd test && make test-back-end'
            }
        }
    }
}

You need to create a Pipeline type of a project and specify the SCM configuration in the General tab. In the Pipeline tab, you will have option to select Pipeline script or Pipeline script from SCM . It's always better to start with the Pipeline script while you are building and modifying your workflow. Once it's stabilized, you can add it to the repository.
