It's 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 the sh docker build . -t <tag> in your pipeline stage block to run the docker build command.

Docker run: you can use the 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 trainwithshubham/django-app:latest'
            }
        }
    }

Task 1

---

1) Create a docker-integrated Jenkins declarative pipeline

• Set up the Jenkins server.

• In Jenkins, Click on “New Item”, create a new pipeline job, and select "Pipeline" as the project type.

• In the configuration, In the pipeline script section, define your stages, steps, and parameters.

• Save and run the pipeline. You should see the pipeline execute each stage and run your application inside a Docker container.

• See the Console Output:

• 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

Task 2

---

• 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.

• See the Console Output:
