Docker Compose部署微服务项目上线功能
作者:Bug 终结者
这篇文章主要介绍了Docker Compose部署微服务项目上线,需求是这样的编写一个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,本文给大家分享实现思路,需要的朋友可以参考下
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
