一、Compose入門案例

流程：

需要定義一個docker-compose.yml文件----工程

需要在docker-compose文件配置依賴服務(wù)

docker-compose up 執(zhí)行該文件

1. 依賴

創(chuàng)建springboot項(xiàng)目

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.1</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>

2. 實(shí)體類

package com.gblfy.entity;import com.baomidou.mybatisplus.annotation.TableName; import lombok.*;/**** @Author gblfy* @Date 2022-03-20 8:18**/ @Data @ToString @EqualsAndHashCode @AllArgsConstructor @NoArgsConstructor @TableName("docker_compose_entity") public class DockerComposeEntity {private Integer id;private String name; }

3. mapper接口

package com.gblfy.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.gblfy.entity.DockerComposeEntity;/**** @Author gblfy* @Date 2022-03-20 8:17**/ public interface DockerComposeMapper extends BaseMapper<DockerComposeEntity> { }

4. 啟動類

package com.gblfy;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication @MapperScan("com.gblfy.mapper") public class DockerComposeApplication {public static void main(String[] args) {SpringApplication.run(DockerComposeApplication.class, args);}}

5. yml配置

spring:datasource:url: jdbc:mysql://mysql:3306/docker-compose-boot?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTCusername: rootpassword: 123456driver-class-name: com.mysql.cj.jdbc.Driver server:###端口號port: 8080servlet:##設(shè)置springboot項(xiàng)目訪問路徑context-path: /gblfy

6. 測試案例

package com.gblfy;import com.gblfy.entity.DockerComposeEntity; import com.gblfy.mapper.DockerComposeMapper; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;/**** @Author gblfy* @Date 2022-03-20 8:16**/ @RestController public class DockerComposeController {@Resourceprivate DockerComposeMapper dockerComposeMapper;@PostMapping("/insert")public String insert() {DockerComposeEntity dockerComposeEntity = new DockerComposeEntity();dockerComposeEntity.setId(1);dockerComposeEntity.setName("zhangsan");dockerComposeMapper.insert(dockerComposeEntity);return "success";} }

7. 打包

mvn clean package -Dmaven.test.skip=true

二、制作 DockerFile和docker-compose.yml

2.1. 制作 DockerFile

# Docker image for springboot file run #VERSION 0.0.1 #Author: GBLFY # 基礎(chǔ)鏡像使用java FROM java:8 # 作者 MAINTAINER gblfy.com # VOLUME 指定了臨時文件目錄為/tmp。 # 其效果是在主機(jī) /var/lib/docker 目錄下創(chuàng)建了一個臨時文件，并鏈接到容器的/tmp,測試可以這樣，企業(yè)中這里建議docker真實(shí)目錄并賦予權(quán)限 VOLUME /tmp # 將jar包添加到容器中并更名為docker-compose-boot.jar ADD docker-compose-0.0.1-SNAPSHOT.jar docker-compose-boot.jar # 運(yùn)行jar包 RUN bash -c 'touch /docker-compose-boot.jar' ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/docker-compose-boot.jar"] #暴露8080端口 EXPOSE 8080

2.2. docker-compose.yml

version: "3.0" services:mysql: # mysql服務(wù)image: mysql:5.7command: --default-authentication-plugin=mysql_native_password #解決外部無法訪問ports:- "3306:3306" #容器端口映射到宿主機(jī)的端口environment:MYSQL_ROOT_PASSWORD: 'root'MYSQL_ALLOW_EMPTY_PASSWORD: 'no'MYSQL_DATABASE: 'docker-compose-boot'MYSQL_USER: 'gblfy'MYSQL_PASSWORD: '123456'networks:- gblfy_webdocker-compose-boot-web: #自己單獨(dú)的springboot項(xiàng)目hostname: gblfybuild: ./ #需要構(gòu)建的Dockerfile文件ports:- "38000:8080" #容器端口映射到宿主機(jī)的端口depends_on: #web服務(wù)依賴mysql服務(wù)，要等mysql服務(wù)先啟動- mysqlnetworks:- gblfy_web networks: ## 定義服務(wù)的橋gblfy_web:

這里演示為了看測試效果，關(guān)鍵的目錄映射沒有設(shè)置，企業(yè)中是需要把數(shù)據(jù)目錄和日志目錄映射到宿主機(jī)目錄，簡言之，目錄掛載

三、打包部署

3.1. 資料上傳

docker-compose-0.0.1-SNAPSHOT.jar docker-compose.yml Dockerfile

3.2. 啟動docker-compose

cd /app/docker-compose-boot docker-compose up

日志（拉取mysql5.7鏡像和jdk8鏡像我已經(jīng)操作過了，下面日志是將springboot項(xiàng)目打包成鏡像）

3.3. 創(chuàng)建表

3.4. 接口測試

http://192.168.92.134:38000/gblfy/insert

3.5. 數(shù)據(jù)驗(yàn)證

3.6. Compose常用命令

docker-compose -h # 查看幫助docker-compose up # 創(chuàng)建并運(yùn)行所有容器 docker-compose up -d # 創(chuàng)建并后臺運(yùn)行所有容器 docker-compose -f docker-compose.yml up -d # 指定模板 docker-compose down # 停止并刪除容器、網(wǎng)絡(luò)、卷、鏡像。docker-compose logs # 查看容器輸出日志 docker-compose pull # 拉取依賴鏡像 dokcer-compose config # 檢查配置 dokcer-compose config -q # 檢查配置，有問題才有輸出docker-compose restart # 重啟服務(wù) docker-compose start # 啟動服務(wù) docker-compose stop # 停止服務(wù)
