最简单配置jenkins容器使用宿主机的docker方法

构建镜像和发布镜像到harbor都需要使用到docker命令。而在Jenkins容器内部安装Docker官方推荐直接采用宿主机带的Docker即可

设置Jenkins容器使用宿主机Docker

设置宿主机docker.sock权限

chown root:root /var/run/docker.sock

chmod o+rw /var/run/docker.sock

添加数据卷

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

添加构建操作

添加参数化部署，这里添加一个参数projectVersion，用来给镜像指定具体的版本

将原来使用over ssh推送jar及dockerFile文件的构建后操作步骤删除

在代码质量检测完成后执行镜像打包操作,并把镜像推送到目标服务器上

mv target/*.jar docker/
docker build -t mytest:${projectVersion} docker/
docker login -u admin -p Harbor12345 192.168.19.7:80
docker tag mytest:${projectVersion} 192.168.19.7:80/repo/mytest:${projectVersion}
docker push 192.168.19.7:80/repo/mytest:${projectVersion}

编写部署脚本

在代码部署的服务器上编写如下脚本deploy,并且将脚本移动环境变量中：

[root@localhost bin]# ls /usr/bin/ | grep deploy.sh
deploy.sh

[root@localhost bin]# cat /usr/bin/deploy.sh
harbor_url=$1
harbor_project_name=$2
project_name=$3
tag=$4
port=$5

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"
fi

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

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

docker login -u admin -p Harbor12345 $harbor_url

docker pull $imageName

docker run -d -p $port:8080 --name $project_name $imageName

echo "Start Container Success"
echo $project_name
