环境要求

已安装docker并设置为开机自启
已安装Docker-Compose

Jenkins

基于docker安装Jenkins

jenkins官网

https://www.jenkins.io/

wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
yum -y install jenkins

编写docker-compose.yml文件

vi /usr/local/docker/jenkins_docker/docker-compose.yml

version: "3.1"
services:
  jenkins:
    image: jenkins/jenkins:2.401.2-lts
    container_name: jenkins
    ports:
      - 8080:8080
      - 50000:50000
    volumes:
      - ./data/:/var/jenkins_home/

首次启动会因为数据卷data目录没有权限导致启动失败，设置data目录写权限(/usr/local/docker/jenkins_docker/data)

chmod -R a+w data/

启动jenkins

在/usr/local/docker/jenkins_docker目录下执行

/usr/local/docker/jenkins_docker/docker-compose restart

访问地址

http://192.168.56.103:8080/

账号密码

root/root

配置源码拉取地址

点击构建下载源码

源码位置

/usr/local/docker/jenkins_docker/data/workspace

配置Maven构建代码

配置maven

配置jdk

新建任务

clean package -DskipTest

坑死人不偿命,有可能maven变了,地下的settings.xml不边,需要核对

发送到目标服务器

配置ssh

将spring-boot项目打包成docker镜像并在目标服务器运行

项目src同级添加docker目录,并在docker目录下创建DockerFile

FROM daocloud.io/library/java:8u40-jdk
COPY hello-jenkins-0.0.1-SNAPSHOT.jar /usr/local/
WORKDIR /usr/local
CMD java -jar hello-jenkins-0.0.1-SNAPSHOT.jar

解释:

FROM daocloud.io/library/java:8u40-jdk 基于aocloud.io/library/java:8u40-jdk镜像构建
COPY hello-jenkins-0.0.1-SNAPSHOT.jar /usr/local/ 将主机上得hello-jenkins-0.0.1-SNAPSHOT.jar复制到(生成的)容器内的/usr/local/ 目录下
WORKDIR /usr/local 容器的工作目录，这意味着后续的命令将在这个目录下执行。你的可执行JAR文件也位于这个目录中。
CMD java -jar hello-jenkins-0.0.1-SNAPSHOT.jar 容器启动时执行的默认命令
只需要修改一下jar即可

在docker目录下新建docker-compose.yml文件

version: "3.1"
services:
  hello-jenkins:
    build:
      context: ./
      dockerfile: DockerFile
    image: hello-jenkins:v1.0.0
    container_name: hello-jenkins
    ports:
      - 80:80

解释:

hello-jenkins：

这是服务的名称，你可以根据需要将其更改为你喜欢的名称。

遇到的坑:关闭防火墙之后拉去不到代码了,开启防火墙之后就正常了.

参数化构建

cd /var/jenkins_home/workspace/hello-jenkins-parameter
git checkout $release
/var/jenkins_home/maven/bin/mvn package -DskipTests

Harbor

Habor需要2G左右的磁盘,请确保磁盘够用

vim /etc/docker/daemon.json

{
    "registry-mirrors": [
       "https://d8b3zdiw.mirror.aliyuncs.com"
    ],
 
    "insecure-registries": [
       "192.168.56.103:80"
    ]
}

注意:80一定要写,要不然很有可能走443,然后报安全问题

重启docker

systemctl daemon-reload
systemctl restart docker

重启docker后harbor只启动了一下6个服务,需要重启harbor

harbor-jobservice
harbor-db
registry
redis
registryctl
harbor-log

cd /usr/local/harbor
docker-compose restart

完整的harbor服务

harbor-jobservice
nginx
harbor-core
harbor-portal
harbor-db
registry
redis
registryctl
harbor-log

登录仓库

docker login -u DevOps -p 1qaz@WSX 192.168.56.103:80

注意:80一定要写(默认端口不一定就是80还有443)

添加镜像tag

docker tag 66a03cc3266e 192.168.56.103:80/hello-jenkins/hello-jenkins:v1.0.0

REPOSITORY                                      TAG           IMAGE ID       CREATED         SIZE
192.168.56.103:80/hello-jenkins/hello-jenkins   v1.0.0        66a03cc3266e   28 hours ago    847MB
hello-jenkins                                   v1.0.0        66a03cc3266e   28 hours ago    847MB

推送镜像

docker push 192.168.56.103:80/hello-jenkins/hello-jenkins:v1.0.0

在jenkins内部使用宿主机docker

修改宿主机docker.sock权限：

chown root:root /var/run/docker.sock
chmod o+rw /var/run/docker.sock

为jenkins添加数据卷

vim /usr/local/docker/jenkins_docker/docker-compose.yml

version: "3.1"
services:
  jenkins:
    image: jenkins/jenkins:2.401.2-lts
    container_name: jenkins
    ports:
      - 8080:8080
      - 50000:50000
    volumes:
      - ./data/:/var/jenkins_home/
      - /usr/bin/docker:/usr/bin/docker
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/docker/daemon.json:/etc/docker/daemon.json

docker-compose up -d

补充:

docker-compose up -d 创建docker-compose中定义的服务,并启动容器.

docker-compose只会启动通过docker-compose up -d创建好的处于停止状态的容器

添加构建后操作

mv target/*.jar docker/
docker build -t hello-jenkins:$tag -f docker/DockerFile docker/
docker login -u admin -p Harbor12345 192.168.56.103:80
docker tag hello-jenkins:$tag 192.168.56.103:80/hello-jenkins/hello-jenkins:$tag 
docker push 192.168.56.103:80/hello-jenkins/hello-jenkins:$tag

/var/jenkins_home/workspace/hello-jenkins-parameter

默认会找Dockerfile,因为项目里面的名字是DockerFile所以要通过-f指定

部署

部署脚本

harbor_url=$1
harbor_project_name=$2
project_name=$3
tag=$4
port=$5

# 定义要追加输出的文件路径
output_file="/root/deploy.log"
imageName=$harbor_url/$harbor_project_name/$project_name:$tag

containerId=`docker ps -a | grep ${project_name} | awk '{print $1}'`
if [ "$containerId" != "" ] ; then
    docker stop $containerId
    docker rm $containerId 
    echo "Delete Container Success" | tee -a "$output_file"
fi

imageId=`docker images | grep ${project_name} | awk '{print $3}'`

if [ "$imageId" != "" ] ; then
    docker rmi -f $imageId
    echo "Delete Image Success" | tee -a "$output_file"
fi

docker login -u DevOps -p '1qaz@WSX' $harbor_url

docker pull $imageName

docker run -d -p $port:$port --name $project_name $imageName

echo "Start Container Success" | tee -a "$output_file"
echo $project_name | tee -a "$output_file"

添加构建后操作

Send build artifacts over SSH

deploy.sh 192.168.56.103:80 hello-jenkins ${JOB_NAME} $tag $container_port $port

k8s

# 修改 hostname
hostnamectl set-hostname k8smaster
# 查看修改结果
hostnamectl status
# 设置 hostname 解析
echo "127.0.0.1   $(hostname)" >> /etc/hosts
