What is stage block in Jenkins?
A stage block defines a conceptually distinct subset of tasks performed through the entire Pipeline (e.g. "Build", "Test" and "Deploy" stages), which is used by many plugins to visualize or present Jenkins Pipeline status/progress. [ 6]
Is Jenkinsfile the same as Pipeline?
While the syntax for defining a Pipeline, either in the web UI or with a Jenkinsfile is the same, it is generally considered best practice to define the Pipeline in a Jenkinsfile and check that in to source control .
Why use Jenkins pipeline?

Scripted Jenkins pipeline runs on the Jenkins master with the help of a lightweight executor. It uses very few resources to translate the pipeline into atomic commands. Both declarative and scripted syntax are different from each other and are defined totally differently.
What is Declarative Pipeline Syntax?
Declarative pipeline syntax offers an easy way to create pipelines. It contains a predefined hierarchy to create Jenkins pipelines. It gives you the ability to control all aspects of a pipeline execution in a simple, straight-forward manner.
What are the benefits of using Jenkinsfile?
The benefits of using JenkinsFile are: You can create pipelines automatically for all branches and execute pull requests with just one JenkinsFile. You can review your Jenkins code on the pipeline. You can audit your Jenkins pipeline. This is the singular source for your pipeline and can be modified by multiple users.
What does the red button mean in Jenkins?
When the Jenkins pipeline is running, you can check its status with the help of Red and Green status symbols. Red means the pipeline has failed, while green indicates success. In this Jenkins pipeline example, we see that the button is green. Hence, the pipeline is successful.

Stage. A “stage” is a step that calls supported APIs. Pipeline syntax is comprised of stages. Each stage can have one or more build steps within it. Familiarity with Jenkins terms such as “controller,” “agent”, and “executor” also helps with understanding how pipelines work. These terms are not specific to pipelines:

Integrate BitBucket & Jenkins
Connect Jenkins and Bitbucket. And trigger a job automatically in Jenkins when a new code is committed in Bitbucket.
1. Create Repo Using BitBucket
First, you need a BitBucket account. Register and log in to BitBucket using the given link.
2. Install the Bitbucket plugin in Jenkins
Log in to the Jenkins server and go to Manage Jenkins. If you don’t have Jenkins, please refer this link.
4. Push code to Jenkins when new code is committed using BitBucket webhooks
The final step of the integration is to configure the BitBucket to push the code changes to the Jenkins server whenever a new code is committed to the repository.
5. Test the BitBucket and Jenkins Integration
To test the integration, click the Build Now button in the Jenkins Job.
Summary
You can find many theories about the DevOps process on the internet. Only a few articles demonstrate how to use the DevOps tools in a real-time project. When I was new to DevOps I found only theories. I always want to contribute to the community of people. This article explains how to connect and trigger the job using Jenkins and Bitbucket.
