Docker Compose部署微服务项目上线功能

目录一、需求说明二、效果图三、项目结构四、核心源码♻️Java依赖与接口♨️Docker相关源码五、部署项目⛵小结

一、需求说明

编写一个SpringBoot + Redis 的微服务项目，并提供 hello接口，每访问一次接口，计数器+1

二、效果图

三、项目结构

目录说明

docker-compose.yml ：项目的启动文件，配置编排等

Dockerfile：项目上线所需要的依赖，以及启动方式

四、核心源码

♻️Java依赖与接口

依赖文件

pom.xml

<?xml version=”1.0″ encoding=”UTF-8″?> <project xmlns=”http://maven.apache.org/POM/4.0.0″ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd”> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.5.5</version> <relativePath/> <!– lookup parent from repository –> </parent> <groupId>org.example</groupId> <artifactId>demo</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> <exclusions> <exclusion> <groupId>io.lettuce</groupId> <artifactId>lettuce-core</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> </resource> <resource> <directory>libs/</directory> <targetPath>libs</targetPath> <includes> <include>**/*.jar</include> </includes> </resource> </resources> </build> </project>

接口

HelloController

package com.wanshi.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.StringRedisTemplate; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; /** * @author whc * @date 2022/6/9 10:06 */ @RestController public class HelloController { @Autowired private StringRedisTemplate redisTemplate; @GetMapping(“/hello”) public String hello() { Long views = redisTemplate.opsForValue().increment(“views”); return “hello, xiaowang, views:” + views; } }

配置文件

application.yml

server: port: 8080 spring: redis: host: redis

♨️Docker相关源码

Dockerfile

FROM java:8 COPY *.jar /app.jar CMD [“–server.port=8080”] EXPOSE 8080 ENTRYPOINT [“java”, “-jar”, “/app.jar”]

docker-compose.yml

version: 3.8 services: xiwoangapp: build: . image: xiaowangapp depends_on: – redis ports: – “8080:8080” redis: image: “redis:3.0.7”

五、部署项目

打包后端项目通过命令

mvn clean package

jar包与配置文件上传至Linux服务器，新建指定文件夹（通过Filezilla上传文件）

执行命令启动

docker-compose up

部署成功后我们查看服务是否启动

docker ps

本机进行访问

curl localhost:8080/hello
