Kubernetes自动化配置部署

news 2025/8/5 14:12:01

在新建工程中，使用k8s的devops服务，自动化部署项目

1、在搭建好k8s的集群中，确认已开启devops服务；

2、新建Maven项目之后，创建dockerfile、deploy和Jenkins文件

例如：

Dockerfile

FROM bairong.k8s.master1/br-sjzl/tomcat:9.0-jdk8-temurin-focalENV TZ=Asia/ShanghaiRUN mkdir /usr/local/tomcat/webapps/userfilesCOPY bairong-web/target/*.war /usr/local/tomcat/webapps/

Deploy.yaml
