Day 27 Task: Jenkins Declarative Pipeline with Docker

#90DAYSOFDEVOPSCHALLENGE

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.

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

How will the stages look

stages {
        stage('Build') {
            steps {
                sh 'docker build -t basanagoudapatil02/django-app:latest'
            }
        }
    }

Task-01

• Create a docker-integrated Jenkins declarative pipeline

1. Login to Jenkins and click on new item, Provide desired name and select “Pipeline” and click on “Ok” button.

2. Use the below-given syntax using sh inside the stage block

pipline {
    agent any 
    
    stages{
        stages('code'){
            steps{
                git url:'https://github.com/Basanagoudapatil02/django-todo.git',branch 'main'
            }
        }
        
        stage('Build'){
            Steps{
                sh'docker build . -t react-django-docker-img:latest'
            }
        }
        
        stage('Test'){
            Steps{
                echo "Testing"
            }
        }
        
        stage('Deploy'){
            Steps{
                sh "docker run -d react-django-docker-jenkins -p 8001:8001 react-django-docker-img:lastest"
            }
        }
    }   
}

3. Click on Save. Click on “Build Now”.

• You will face errors in case of running a job twice, as the docker container will be already created, so for that do task 2

1. Run the pipeline once again by clicking on the “Build Now” button from the dashboard.

2. Error will pop up when we run the same job twice.

Task-02

• Create a docker-integrated Jenkins declarative pipeline using the docker groovy syntax inside the stage block.

Click on Save and then click on Build Now.

Happy Learning:)
