# 第一章介绍

本套系统搭建在k8s之上，采用kubesphere进行管理

之前为了方便，有介绍过kubesphere基础组件的搭建，比如redis、nacos等，这里将会直接从服务部署开始

# 第二章网关流水线创建

流水线流程分为一下及步

拉取代码
编译打包
Build Docker镜像，镜像打标签
上传镜像到阿里云
部署

# 2.1 镜像拉取凭证

部署时需要拉取镜像，这里配置相关秘钥

信息输入完成可以点击验证测试

# 2.2 流水线凭证

流水线在编写时需要登录阿里云镜像，所以需要相关凭证

# 2.3 工程中添加Dockerfile

FROM openjdk:8-jdk
LABEL maintainer=zhishun.cai


#docker run -e PARAMS="--server.port 9090"
# ENV PARAMS="--server.port=8080 --spring.profiles.active=prod --spring.cloud.nacos.discovery.server-addr=nacos.wogua-cloud:8848 --spring.cloud.nacos.config.server-addr=nacos.wogua-cloud:8848 --spring.cloud.nacos.config.namespace=prod --spring.cloud.nacos.discovery.namespace=prod --spring.cloud.nacos.config.file-extension=yml"
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone

COPY target/*.jar /app.jar
EXPOSE 8080

#
ENTRYPOINT ["/bin/sh","-c","java -Dfile.encoding=utf8 -Djava.security.egd=file:/dev/./urandom -jar app.jar"]

# 2.4 Gateway配置多环境

Gateway Pom文件中添加

在流水线打包时指定相应环境即可

在工程先创建文件夹config

在config中创建deploy.yml文件
