一、Jenkins + K8S + Gitlab构建RLEASE打包发布更新流水线到K8S集群¶
1.1 Jenkins + K8S + Gitlab构建RLEASE打包发布更新流水线到K8S集群¶
获取运行中deploy的yaml -> 上传到gitlab -> 更新Container Image （打包jar包 -> 创建新的Image -> 上传Image到Docker Hub） -> 上传到gitlab (yaml) -> 将新的yaml apply 到集群中
1.2 配置Prod-Release流水线构建镜像¶
1.2.1 Release测试流水线¶
- 代码 -> 编译 -> 单测 -> 打包 -> 扫描 -> 接口测试 -> 镜像 -> 发布 -> 生成版本文件 -> 邮件通知
1.2.2 Docker in Docker配置¶
你可以在K8S 集群中 Run K8S Pod as Agent
- name: dockersock
hostPath:
path: /var/run/docker.sock
- name: dockercmd
hostPath:
path: /usr/local/bin/docker
1.2.3 创建一个凭据存储registry仓库的账号和密码¶
ID: docker-registry-admin
1.2.4 添加Dockerfile到 项目中demo-maven-service¶
Dockerfile
FROM openjdk:8-alpine
MAINTAINER devops
ADD target/*.jar /app.jar
## 执行命令
ENTRYPOINT ["java","-jar","/app.jar"]
1.2.5 创建BuildImage pipeline¶
stage("BuildImages"){
steps{
script{
env.serviceName = "${JOB_NAME}".split("_")[0]
withCredentials([usernamePassword(credentialsId: 'docker-registry-admin', passwordVariable: 'password', usernameVariable: 'username')]) {
env.dockerImage = "nyjxi/${serviceName}:${branchName}"
sh """
docker login -u ${username} -p ${password}
docker build -t nyjxi/${serviceName}:${branchName} .
sleep 1
docker push nyjxi/${serviceName}:${branchName}
sleep 1
#docker rmi nyjxi/devopstest/${serviceName}:${branchName}
"""
}
}
}
}
