Migrating your CI/CD pipelines from Jenkins to Bitbucket Pipelines

According to RedHat

A continuous integration and continuous deployment (CI/CD) pipeline is a series of steps that must be performed in order to deliver a new version of software. CI/CD pipelines are a practice focused on improving software delivery throughout the software development life cycle via automation. 

Both Jenkins and Bitbucket have their own implementation of Pipeline features. Jenkins historically used to have Freestyle builds. But, a few years ago, Jenkins embraced Pipeline builds as a more modern, up-to-date paradigm for CI/CD. Suppose you are migrating from a Jenkins Pipeline to a Bitbucket Pipeline. In that case, it is mostly a matter of translating the Jenkinsfile syntax to the bitbucket-pipeline.yml file described in the BitBucket documentation.

Here is an example of a simple Jenkinsfile:

				
					pipeline {
    agent any
 
    stages {
        stage('Build') {
            steps {
                echo 'Building..'
            }
        }
        stage('Test') {
            steps {
                echo 'Testing..'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying....'
            }
        }
    }
}
				
			

Here is an example of a simple bitbucket-pipeline.yml: 

				
					pipelines:
  branches:
  master:
    - step:
      name: Build
      script:
      - echo 'Building..'
- step:
      name: Test
      script:
      - echo 'Testing...'
- step:
      name: Deploy
      script:
      - echo 'Deploying....'
				
			

The examples for each tool above were intentionally kept simple for readability. Below you will find are some key, high-level differences between both tools:

Suppose you are ready to migrate to Bitbucket Pipelines. In that case, you should also reference some of the other key concepts, as shown visually in the diagram below and documented on this page
