Jenkins+Kubernetes CI/CD
Jenkins + Kubernetes CI/CD
步骤如下
- 安装Kubernetes集群
- 开通容器镜像服务，创建镜像仓库，如ycdocker/demo
- 在集群外的ECS上安装Jenkins
-
在Jenkins所在ECS安装kubectl，用以访问Kubernetes集群
wget https://dl.k8s.io/v1.10.6/kubernetes-client-linux-amd64.tar.gz tar -xvf kubernetes-client-linux-amd64.tar.gz cd kubernetes/client/bin chmod +x ./kubectl sudo mv ./kubectl /usr/local/bin/kubectl mkdir /root/.kube vi /root/.kube/config -
安装Docker
# step 1: 安装必要的一些系统工具 sudo apt-get update sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common # step 2: 安装GPG证书 curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add - # Step 3: 写入软件源信息 sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" # Step 4: 更新并安装 Docker-CE sudo apt-get -y update sudo apt-get -y install docker-ce - 安装maven
apt-get install maven -y -
选择Spring Boot Demo项目，Dockerfile放根目录
FROM openjdk:8-jdk-alpine VOLUME /tmp ARG JAR_FILE COPY ${JAR_FILE} app.jar ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] - 上传代码到Git
- 登陆Jenkins，创建free style项目
- 配置Jenkins从Git取代码
- 添加构建步骤，Shell脚本如下
mvn clean package
docker build --build-arg JAR_FILE=target/gs-spring-boot-docker-0.1.0.jar -t registry.cn-beijing.aliyuncs.com/ycdocker/demo:$BUILD_NUMBER .
docker login --username=***** --password=***** registry.cn-beijing.aliyuncs.com
docker push registry.cn-beijing.aliyuncs.com/ycdocker/demo:$BUILD_NUMBER
kubectl set image deployment/demo demo=registry.cn-beijing.aliyuncs.com/ycdocker/demo:$BUILD_NUMBER- 修改代码测试效果
