Jenkins官网实例----Build a Java app with Maven
Build a Java app with Maven
来自 <https://www.jenkins.io/doc/tutorials/build-a-java-app-with-maven/>
先创建network
docker network create jenkins
运行容器jenkins-docker，网络别名为docker。
docker run \
--name jenkins-docker \
--rm \
--detach \
--privileged \
--network jenkins \
--network-alias docker \
--env DOCKER_TLS_CERTDIR=/certs \
--volume jenkins-docker-certs:/certs/client \
--volume jenkins-data:/var/jenkins_home \
--publish 2376:2376 \
--publish 3000:3000 --publish 5000:5000 \
docker:dind \
--storage-driver overlay2
vi Dockerfile
FROM jenkins/jenkins:2.387.1
USER root
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
https://download.docker.com/linux/debian \
$(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean docker-workflow"
构建
docker build -t myjenkins-blueocean:2.387.1-1 .
修改版：
FROM jenkins/jenkins:2.387.1
USER root
ENV http_proxy=http://deb.debian.org/debian/dists/bullseye/InRelease
ENV https_proxy=https://deb.debian.org/debian/dists/bullseye/InRelease
ENV http_proxy=http://deb.debian.org/debian-security/dists/bullseye-security/InRelease
ENV https_proxy=https://deb.debian.org/debian-security/dists/bullseye-security/InRelease
ENV http_proxy=http://deb.debian.org/debian/dists/bullseye-updates/InRelease
ENV https_proxy=https://deb.debian.org/debian/dists/bullseye-updates/InRelease
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
https://download.docker.com/linux/debian \
$(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean docker-workflow"
排错参考：
Docker Error: Could not connect to deb.debian.org (111: Connection refused) [closed]
实测无效，后面重启服务器后正常。
第8步有点慢
Run your own myjenkins-blueocean:2.387.1-1 image as a container in Docker
docker run \
--name jenkins-blueocean \
--detach \
--network jenkins \
--env DOCKER_HOST=tcp://docker:2376 \
--env DOCKER_CERT_PATH=/certs/client \
--env DOCKER_TLS_VERIFY=1 \
--publish 8080:8080 \
--publish 50000:50000 \
--volume jenkins-data:/var/jenkins_home \
--volume jenkins-docker-certs:/certs/client:ro \
--volume "$HOME":/home \
--restart=on-failure \
--env JAVA_OPTS="-Dhudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true" \
myjenkins-blueocean:2.387.1-1
Display the Jenkins console log with the command:
docker logs jenkins-blueocean
git clone github后推到自己的gitlab
克隆并推送到gitlab
git clone https://github.com/jenkins-docs/simple-java-maven-app.git
git remote -v
origin https://github.com/jenkins-docs/simple-java-maven-app.git (fetch)
origin https://github.com/jenkins-docs/simple-java-maven-app.git (push)
git remote remove origin
git remote add origin http://192.168.1.143/root/simple-java-maven-app.git
git remote -v
origin http://192.168.1.143/root/simple-java-maven-app.git (fetch)
origin http://192.168.1.143/root/simple-java-maven-app.git (push)
git push -u origin --all
在根目录创建文件Jenkinsfile并重新推送
cat Jenkinsfile
pipeline {
agent {
docker {
image 'maven:3.9.0-eclipse-temurin-11'
args '-v /root/.m2:/root/.m2'
}
}
options {
skipStagesAfterUnstable()
}
stages {
stage('Build')
{
steps {
sh 'mvn -B -DskipTests clean package'
}
}
stage('Test')
{
steps {
sh 'mvn test'
}
post {
always {
junit 'target/surefire-reports/*.xml'
}
}
}
stage('Deliver')
{
steps {
sh './jenkins/scripts/deliver.sh'
}
}
}
}
git add .
git commit -m "add Jenkinsfile"
git push
Jenkins创建流水线
simple-java-maven-app
排错
构建失败
修改DNS不成功
[root@localhost jenkins]# docker exec -it 0e48a9cc38b1 /bin/bash
jenkins@0e48a9cc38b1:/$ cat /etc/resolv.conf
nameserver 127.0.0.11
options ndots:0
修改为以下，也无效。
docker run \
--name jenkins-blueocean \
--detach \
--network jenkins \
--env DOCKER_HOST=tcp://docker:2376 \
--env DOCKER_CERT_PATH=/certs/client \
--env DOCKER_TLS_VERIFY=1 \
--publish 8080:8080 \
--publish 50000:50000 \
--volume jenkins-data:/var/jenkins_home \
--volume jenkins-docker-certs:/certs/client:ro \
--volume "$HOME":/home \
--restart=on-failure \
--env JAVA_OPTS="-Dhudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true" \
--dns=8.8.8.8 \
myjenkins-blueocean:2.387.1-1
经检查是容器jenkins-docker（网络别名为docker）停用了导致了！
上面报错显示是从此地址去获取镜像 https://docker:2376
--network-alias docker \
Makes the Docker in Docker container available as the hostname docker within the jenkins network.
