Jenkins fails to build with docker - docker

Question

I'm trying to build my Maven project with Jenkins and Docker.
I prepared following Jenkinsfile inside my repository.
pipeline {
agent none
stages {
stage('3-jdk-8') {
agent {
docker {
registryUrl 'https://registry.hub.docker.com'
registryCredentialsId 'docker-hub'
image 'maven:3-jdk-8'
args '-v $HOME/.m2:/root/.m2'
reuseNode true
}
}
steps {
sh 'mvnw -B clean build'
}
}
stage('3-jdk-11') {
agent {
docker {
registryUrl 'https://registry.hub.docker.com'
registryCredentialsId 'docker-hub'
image 'maven:3-jdk-11'
args '-v $HOME/.m2:/root/.m2'
reuseNode true
}
}
steps {
sh 'mvnw -B clean build'
}
}
}
}
When I trigger the item, I got this.

Jenkins (Docker Daemon) cannot find the image. Or in other words cannot find the registry.
+ docker pull registry.hub.docker.com/maven:3-jdk-8
Error response from daemon: unauthorized: authentication required
You just need to modify the registry URL in the config with docker.io like this.
stage('3-jdk-8') {
agent {
docker {
registryUrl 'https://docker.io'
registryCredentialsId 'docker-hub'
image 'maven:3-jdk-8'
args '-v $HOME/.m2:/root/.m2'
reuseNode true
}
}
Or you can omit the registryUrl and registryCredentialsId since the maven image is in the public registry (Docker Hub). And Jenkins will try to pull it from there by default.
stage('3-jdk-8') {
agent {
docker {
image 'maven:3-jdk-8'
args '-v $HOME/.m2:/root/.m2'
reuseNode true
}
}
