## 一：环境准备
#### 1.kubernetes集群环境
集群环境检查
```shell
[root@master ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
master Ready control-plane,master 11d v1.23.1
node-1 Ready <none> 11d v1.23.1
node-2 Ready <none> 11d v1.23.1
node-3 Ready <none> 11d v1.23.1
```
#### 2.harbor环境
harbor环境检查

## 二：项目准备
#### 1.项目包
#### 2.项目端口准备
| 服务 | 内部端口 | 外部端口 |
| :---------------------: | :------: | -------- |
| tensquare_eureka_server | 10086 | 30020 |
| tensquare_zuul | 10020 | 30021 |
| tensquare_admin_service | 9001 | 30024 |
| tensquare_gathering | 9002 | 30022 |
| mysql | 3306 | 30023 |
## 三：项目部署
#### 1.eureka部署
application.yml文件修改
```
spring:
application:
name: EUREKA-HA
---
#单机配置
server:
port: 10086
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
#defaultZone: http://pod主机名称.service名称:端口/eureka/
```
Dockerfile创建：
```shell
[root@nfs-harbor jdk]# ls
Dockerfile tensquare_eureka_server-1.0-SNAPSHOT.jar jdk-8u211-linux-x64.tar.gz
[root@nfs-harbor jdk]# cat Dockerfile
FROM xingdian
MAINTAINER "xingdian" <xingdian@gmail.com>
ADD jdk-8u211-linux-x64.tar.gz /usr/local/
RUN mv /usr/local/jdk1.8.0_211 /usr/local/java
ENV JAVA_HOME /usr/local/java/
ENV PATH $PATH:$JAVA_HOME/bin
COPY tensquare_eureka_server-1.0-SNAPSHOT.jar /usr/local
EXPOSE 10086
CMD java -jar /usr/local/tensquare_eureka_server-1.0-SNAPSHOT.jar
```
镜像构建：
```shell
[root@nfs-harbor jdk]# docker build -t eureka:v2022.1 .
```
上传到镜像仓库：
```shell
[root@nfs-harbor jdk]# docker tag eureka:v2022.1 10.0.0.230/xingdian/eureka:v2022.1
[root@nfs-harbor jdk]# docker push 10.0.0.230/xingdian/eureka:v2022.1
```
仓库验证：

#### 2.tensquare_zuul部署
Dockerfile创建：
```shell
[root@nfs-harbor jdk]# cat Dockerfile
FROM xingdian
MAINTAINER "xingdian" <xingdian@gmail.com>
ADD jdk-8u211-linux-x64.tar.gz /usr/local/
RUN mv /usr/local/jdk1.8.0_211 /usr/local/java
ENV JAVA_HOME /usr/local/java/
ENV PATH $PATH:$JAVA_HOME/bin
COPY tensquare_zuul-1.0-SNAPSHOT.jar /usr/local
EXPOSE 10020
CMD java -jar /usr/local/tensquare_zuul-1.0-SNAPSHOT.jar
```
