If you are new to Jenkins then Please go through from basic:

Jenkins-Basic

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

stages {
        stage('Build') {
            steps {
                sh 'docker build -t chanchal8765/jenkins-docker-image:latest'
            }
        }
    }

Task-01

Create a docker-integrated Jenkins declarative pipeline. Use the above-given syntax using sh inside the stage block. 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

Step 1: Create a new job.

Step 2: Enter the name of the pipeline and select "pipeline".

Step 3: Write the Script for the pipeline and click on "Save".

Step 4: Run the pipeline by clicking on "Build Now".

Step 5: After running the pipeline Check the Console Output.

It's failing because that port is already assigned to a particular container.

Step 6: Pipeline Status "failed".

Task-02

Create a docker-integrated Jenkins declarative pipeline using the docker Groovy syntax inside the stage block. Complete your previous projects using this Declarative pipeline approach.

Step 1: For running the pipeline with docker groovy syntax, required to install plugins related to docker.

Go on Dashboard --> Manage Jenkins --> Plugins --> Click on Serach --> Search docker --> Click on checks --> Click on "Install"

Step 2: Go to pipeline with the same job and use this after that click on "Save".

Step 3: Run the pipeline by clicking on "Build Now".

Step 4: Check Pipeline Status.

Congratulations! Now you can run your pipeline multiple times. It's not giving an error even container exists.
