Task 1

• Create a docker-integrated pipeline with docker

  1. Docker builds: use sh 'docker build. -t <tag> ' to run the docker build command.

  2. Docker run: use sh 'docker run -d <image>' in your pipeline

     to stage block to run the container.

• Now, Steps to do it.Let's Start

  1. create a pipeline

     

  2. use sh syntax in stage block

       pipeline{
            agent any
     
            stages{
                stage("Code Clone"){
                    steps{
                        git branch : 'master', url:'https://github.com/sri766/node-todo-cicd.git'
                    }
                }
            stage("Code Build"){
                    steps{
                        sh 'docker build . -t django-node-todo:latest ' 
                    }
                }
            stage("Code Testing"){
                    steps{
                      echo 'testing'  
                    }
                }
            stage("code Deploy"){
                    steps {
                        sh 'docker run -d -p 8000:8000 django-node-todo:latest'
                    }
                }
            }
        }
     

  3. save and run the pipeline.

     

     console output -

app Is running at port 8000.

Task 2

we can create declarative pipeline with docker by using groovy syntax.

1. replacing deploy code with docker compose up and down command.

     stage("code Deploy"){
                  steps {
                      sh 'docker-compose down'
                      sh 'docker-compose up'
                  }
              }
   

   #possible error may come:

   1. permission denied to run docker commands: just give sudo permission to jenkins by adding sudo to sh commands.

   2. webhooks 403 error: it can be managed. go to manage userProfile-> configure ->generateToken

      copy it and add it to secret while adding webhooks to github.
