在 open-jdk 容器中运行时，sh 命令在 Jenkins 管道中挂起

Question

I am hoping someone can provide me some guidance here:

I'm using jenkins (2.289.3) as a docker container to run some CI jobs in my macbook Monterey. Here is my docker command

docker run -d  \
  -u root \
  --name jenkins \
  -p 9080:8080 \
  -v ./jenkins_home:/var/jenkins_home \
  -v "$HOME":/home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  jenkins

I'm using Jenkinsfile to build a project. Below is the code:

#!/usr/bin/env groovy

node {
    def workspace = pwd()
    
    stage('checkout') {
        checkout scm
        sh "echo checkout" ## this works fine!
    }

    docker.image('openjdk:17-jdk-alpine').inside('-u root -e MAVEN_OPTS="-Duser.home=./my-service/"') {
        stage('check java') {
            sh "java -version" ## this fails!
        }

        stage('artifact build and deploy') {
        
            configFileProvider([configFile(fileId: 'gcRepositoryCred', variable: 'GC_MVN_REPOSITORY_CREDENTIAL'),configFile(fileId: 'maven-settings', variable: 'MAVEN_SETTINGS')]) {
                
                sh "chmod +x my-service/mvnw"
                sh "./my-service/mvnw -f my-service/pom.xml clean deploy -DskipTests -s $MAVEN_SETTINGS"
            }
        }

    }
   
}

It fails at line sh "java -version" inside the open jdk container. Basically it hangs for a while and I get the below error code:

Update The same code works in my another laptop (Mac running Big Sur). The main difference I see is the docker version. Big Sur mac has version 20.10.8 and the machine where it doesn't work has the docker version of 20.10.12.

The another key difference is the log from the working mac. Instead of logging Jenkins does not seem to be running inside a container it says Jenkins is running inside a container . Not sure if they both are related in some way.

I got it working with the following instructions: https://www.jenkins.io/doc/book/installing/docker/

Looks like with the new updates, I need to use docker:dind container to run docker commands and create my own Dockerfile with the provided instructions in the link above.
