Day 26 was all about a Declarative pipeline, now its time to level up things, let's integrate Docker and your Jenkins declarative pipeline

Use your Docker Build and Run Knowledge

docker build - you can use sh 'docker build . -t <tag>' in your pipeline stage block to run the docker build command. (Make sure you have docker installed with correct permissions.

docker run: you can use sh 'docker run -d <image>' in your pipeline stage block to build the container.

How will the stages look

How the Stages Look

Here's an example of how the stages might look in your Jenkins Declarative Pipeline:

pipeline
{
agent any
stages {
    stage('Build') {
        steps {
            sh 'docker build -t your-image-tag .'
        }
    }

    stage('Run') {
        steps {
            sh 'docker run -d your-image-tag'
        }
    }
    stage('Deploy') {
        steps {
            sh 'Deploy throught out cicd'
        }
    }
 }
}

Task 01: Create a Docker-Integrated Jenkins Declarative Pipeline

To create a Docker-integrated Jenkins Declarative Pipeline, follow these steps:

1. Log In: Log in to your Jenkins server and navigate to the Jenkins home page.

2. Create New Item: Click on the "New Item" button on the left-hand side of the screen to create a new Jenkins pipeline.

3. Enter Item Name: In the "Enter an item name" field, type in a name for your new pipeline and select "Pipeline" as the project type.

4. Continue: Click on the "OK" button to proceed.

5. Configure Pipeline: On the next page, scroll down to the "Pipeline" section and select "Pipeline script" as the Definition.

6. Define Pipeline Script: In the Script text area, use the following code and save it

   

   

   

pipeline
{
    agent any
    stages{
    stage("Code")
    {
        steps
        {
            git url : 'https://github.com/anand-raval-git/react_django_demo_app.git' , branch: 'main'
        }
    }
    stage("Build")
    {
        steps
        {
            sh 'docker build . -t anand-raval-git/react_django_demo_app'
        }
    }

    }
}

Step 2: Run the Jenkins Pipeline:

1. To run the pipeline, click on the pipeline name on the Jenkins home page.

2. Click on the "Build Now" button to start the pipeline.

   Check the output of the build:
