Actual behavior build failed in jenkins docker pipeline

Expected behavior build success in jenkins docker pipeline

To Reproduce 1、create jenkinsfile

        CONTAINER_IMAGE_NAME = 'demo'
        CONFIG = credentials('kaniko-auth')
    }

    stages {
        stage('Clone') {
            steps {
                git branch: "${env.GIT_BRANCH}", credentialsId: "${env.GIT_CREDENTIALSID}", url: "${env.GIT_URL}"
            }
        }

        stage('Build_source') {
            agent {
                docker {
                    image 'docker.io/library/maven:latest'
                    args "-v $HOME/.m2:/root/.m2"
                }
            }
            steps {
                sh "mvn -v"
            }
        }

        stage('build_push_image') {
            agent {
                docker {
                    image "${env.BUILDER_IMAGE}"
                    args "--entrypoint="
                    reuseNode true
                }
            }
            steps {
                script {
                    withCredentials([file(credentialsId: 'kaniko-auth1', variable: 'DOCKER_CONFIG1')]) {
                        sh """
                            export DOCKER_CONFIG=/kaniko/docker/
                            mkdir -p /kaniko/docker/
                            cp $DOCKER_CONFIG1 /kaniko/docker/config.json
                            /kaniko/executor --context=dir://. --dockerfile=./Dockerfile --destination=${env.CONTAINER_REGISTRY_URL}/${env.CONTAINER_IMAGE_NAME}:${env.BUILD_NUMBER} --insecure
                        """
                    }
                }
            }
        }
    }
}

2、Dockerfile

RUN apt update -y

I just ran into the same error you described: error building image: error building stage: failed to get filesystem from image: error removing bin to make way for new symlink: unlinkat //bin/sh: permission denied and my problem was that my kaniko pods needed to run as root.

Check if your pipeline is making it running as root here? Since apt-get is a root command, its needs root to be succesful.
