spingboot 容器项目完成CICD部署

部署介绍

传统的项目持续集成，通常由gitlab+jenkins完成项目的持续集成部署。随着容器化技术的日益成熟，很多项目都采用容器化部署管理，本章节则会给大家介绍怎么完成docker项目的持续集成部署

部署架构

部署准备

项目docker化

以springboot项目test-service为例说明，首先需要新建一个Dockerfile文件，内容如下：

FROM java:8
ENV LANG=C.UTF-8
ENV TZ=Asia/Shanghai
ADD test-service.jar   app.jar

CMD ["sh","-c","java -Xmx512m -Xms256m -XX:SurvivorRatio=4 -XX:+UseG1GC -XX:MaxGCPauseMillis=50 -jar -XX:InitiatingHeapOccupancyPercent=70 -Xloggc:/var/log/java_gc.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps app.jar "]

制作生成镜像制品和执行运行容器的脚本

docker images | grep test-service/latest &> /dev/null

if [ $? -ne 0 ]
then
    echo "test-service/latest is not existed,we will docker build it!!!"
    docker build -t test-service/latest .

else
    echo "test-service/latest is existed!!!"
	docker rmi -f test-service/latest
	docker build -t test-service/latest .
fi


docker ps -a| grep test-service &> /dev/null
if [ $? -ne 0 ]
then
    echo "test-service is not up,we will start up it!!!"

   docker run -d -p 8099:8099   --name test-service test-service/latest

else
	docker rm -f  metadata-service
	docker run -d -p 8099:8099   --name test-service metadata-service/latest
    echo "test-service is up!!!"
fi

Jenkins部署配置

构建环境

其中clean的参数说明如下图所示：

构建配置

执行的脚本如下：

cd /home/data/
        rm -rf test-service
        mkdir test-service
        cp /var/lib/docker/volumes/jenkins_data/_data/workspace/test-service/test-service/target/test-service.jar /home/data/test-service
        cp /var/lib/docker/volumes/jenkins_data/_data/workspace/test-service/test-service/Dockerfile /home/data/test-service
        cp /var/lib/docker/volumes/jenkins_data/_data/workspace/test-service/test-service/dockerBuild.sh /home/data/test-service
        cd /home/data/test-service
        chmod -R 777 dockerBuild.sh
        ./dockerBuild.sh
