java后端容器化
思路：
了解在物理机虚拟机的部署流程，然后编写dockerfile进行容器化部署。
java项目，使用mvn进行构建，最终生成jar包，拷贝到jdk环境中启动即可，所以需要多阶段构建。
先启动容器，然后手动构建验证，最后在编写dockerfile进行构建。
# 1.进入maven环境，下载代码，构建得到jar包，pom.xml已经配置好了阿里云的mvn源
docker run --rm -ti aerialist7/maven-git sh #创建一个mvn 、jdk环境git clone https://gitee.com/yuco/eladmin.git
cd /eladminmkdir -p /root/.m2echo '<settings><mirrors><mirror><id>nexus-tencentyun</id><url>https://maven.aliyun.com/repository/public </url><mirrorOf>central</mirrorOf></mirror></mirrors></settings>' > /root/.m2/settings.xml #配置腾讯mvn源地址mvn clean package

编写dockerfile
根据手动编译，咱们已经知道了流程，
1、需要mvn java git环境
2、修改mvn源地址，编译源码
3、生成jar包，启动java -jar eladmin-system-2.6.jar
#准备源码
cd /opt
git clone https://gitee.com/yuco/eladmin.git
FROM aerialist7/maven-git as builderWORKDIR /opt/eladmin
COPY . .
RUN mvn clean packageFROM java:8u111
WORKDIR /opt/eladmin
COPY --from=builder /opt/eladmin/eladmin-system/target/eladmin-system-2.6.jar .
CMD [ "sh", "-c", "java -Dspring.profiles.active=prod -jar eladmin-system-2.6.jar" ]
如上的java参数-Dspring.profiles.active=prod是指可以有多个config.yml配置文件，以在不同的环境下测试。
#构建镜像
docker build -t eladmin:v1 .

要查看 MySQL 中 `test` 数据库的信息，你需要通过 MySQL 命令行工具或任何支持的图形界面工具连接到数据库。下面我会给你一个简单的步骤说明如何使用命令行查看数据库信息。**步骤 1: 连接到 MySQL 数据库**
首先，你需要使用 MySQL 命令行客户端连接到 MySQL 服务器。假设你已经有了适当的权限和认证信息，你可以使用以下命令：```bash
mysql -u username -p
```
这里 `username` 是你的 MySQL 用户名。输入命令后，系统会提示你输入密码。**步骤 2: 选择数据库**
连接成功后，你需要选择 `test` 数据库：```sql
USE test;
```**步骤 3: 查看数据库中的表**
要查看 `test` 数据库中所有的表，你可以使用以下 SQL 命令：```sql
SHOW TABLES;
```**步骤 4: 查看表的结构**
选择一个特定的表，比如 `example_table`，并查看其结构：```sql
DESCRIBE example_table;
```**步骤 5: 查询表中的数据**
查看表中的数据，可以使用 `SELECT` 语句。例如，查看 `example_table` 表中的所有记录：```sql
SELECT * FROM example_table;
```这些步骤将帮助你检查 `test` 数据库中的内容。如果你需要执行特定的查询或有关数据的更复杂的分析，请确保 SQL 语句符合你的需求。
创建redis
[root@localhost redis]# cat docker-compose.yaml

services:redis:command: redis-serverimage: 'redis:3.2'restart: alwayscontainer_name: redisports:- '6379:6379'

前端Vue构建
思路：
- 前端构建需要node环境，构建结果通常为dist静态文件，项目运行仅需要web服务器即可。因此采用多阶构建
- 确认基础镜像：
docker search vue-node - 验证构建，最终采用
codemantn/vue-node作为基础镜像
准备源码
git clone https://gitee.com/yuco/eladmin-web
cd eladmin-web/
修改npm源
npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
npm config set registry https://registry.npm.taobao.com #测试能不能用
npm install
npm run build:prod
生成dist静态文件，把文件内容放到nignx的/usr/share/nginx/html即可
编写dockerfile
FROM codemantn/vue-node AS builderLABEL maintainer="yanfei"# config npm
RUN npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/ && \npm config set registry https://mirrors.huaweicloud.com/repository/npm/WORKDIR /opt/eladmin-web
COPY . .# build
RUN ls -l && npm install && npm run build:prodFROM nginx:alpineWORKDIR /usr/share/nginx/htmlCOPY --from=builder /opt/eladmin-web/dist /usr/share/nginx/html/EXPOSE 80
修改前端代码，后端AIP地址
浏览器——前端——后端
需要在前端代码后面成后端的API地址
[root@localhost eladmin-web]# cat .env.production
ENV = 'production'# 如果使用 Nginx 代理后端接口，那么此处需要改为 '/'，文件查看 Docker 部署篇，Nginx 配置
# 接口地址，注意协议，如果你没有配置 ssl，需要将 https 改为 http
VUE_APP_BASE_API = 'http://192.168.199.142:8000'
# 如果接口是 http 形式， wss 需要改为 ws
VUE_APP_WS_API = 'ws://192.168.199.142:8000'
[root@localhost eladmin-web]# 构建镜像
