Using testcontainers in a Jenkins Docker Agent: containers fail to start, NoRouteToHostException

Question

I\'m using a Jenkins declarative pipeline with Docker Agents to build and test my software, including running integration tests using testcontainers. I can run my testcontai

Answer 1

In my case it was enough to add two arguments to Docker agent options:

• Docker socket as volume
• add --group-add parameter with ID of docker group

pipeline {
    agent any
    stages {
        stage('Gradle build') {
            agent {
                docker {
                    reuseNode true
                    image 'openjdk:11.0-jdk-slim'
                    args  '-v /var/run/docker.sock:/var/run/docker.sock --group-add 992'
                }
            }

            steps {
                sh 'env | sort'
                sh './gradlew build --no-daemon --stacktrace'
            }
        }
    } // stages
} // pipeline
