I am trying to implement complete CICD pipe line. I am running jenkins/jenkins:2.361.1-lts-jdk11 image on docker. to run the docker image I use docker run -p 8080:8080 -p 50000:50000 -d -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock --privileged jenkins/jenkins:2.361.1-lts-jdk11

I have connected to the repo and download the src and build without any issue. Now I need to create a docker image though jenkins and publish in the docker hub. Below is my Jenkinsfile

pipeline{
    agent any
    tools{
        maven 'Maven-3.8.6'
    }
    stages{
    stage('checkout'){
                steps{
                    echo 'checkout the application'
                    git 'https://github.com/hvalola/demo_jenkins'
                }
            }
        stage('build'){
            steps{
                echo 'building the application'
                sh 'mvn package'
            }
        }
        stage('test'){
            steps{
                echo 'testing the application'
            }
        }
        stage('deploy'){
            steps{
                echo 'deploying the application'
            }
        }
        stage('Build docker image'){
            steps{
                script{
                    def dockerHome = tool 'demo-docker'
                    env.PATH = "${dockerHome}/bin:${env.PATH}"
                    sh 'docker build -t pubudurana/demo_jenkins .'
                }
            }
        }
    }
}

My Docker file contains below

FROM openjdk:11
EXPOSE 8090
ADD target/demo_jenkins.jar demo_jenkins.jar
ENTRYPOINT ["java","-jar","/devops-integration.jar"]

But at the time of job running below error occurs

• docker build -t pubudurana/demo_jenkins . Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http:///var/run/docker.sock/v1.29/build?buildargs={}&cachefrom=[]&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels={}&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=pubudurana/demo_jenkins&target=&ulimits=null: dial unix /var/run/docker.sock: connect: permission denied

please help to resolve this issue

CodePudding user response：

you will need to run the docker build command with sudo or otherwise add your user to the docker group.

sudo usermod -aG docker $USER
sudo reboot

I solved the problem by following the below post configuring jenkins

I had to add - DOCKER_HOST=tcp://host.docker.internal:2375 in my docker-compose file
