使用Dokcer+SpringCloud+Consul+Fabio搭建微服务

SpringBoot: 2.1.1
SpringCloud: Greenwich.M3
Consul: consul:1.3.0
Fabio: fabiolb/fabio:1.5.5-go1.9.2

具体的pom.xml和application-dev.yml文件内容可以参考我的GitHub项目

1. Consul

1.1 安装

docker pull consul:1.3.0

1.2 启动

docker run -d -t -p 8300:8300 -p 8301:8301 -p 8302:8302 -p 8500:8500 -p 8600:8600 --name test-consul consul:1.3.0

2. Fabio

2.1 安装

docker pull fabiolb/fabio:1.5.5-go1.9.2

2.2 启动

docker run -d -t -p 9998:9998 -p 9999:9999 --link test-consul:consul -e 'registry_consul_addr=consul:8500' fabiolb/fabio:1.5.5-go1.9.2

3. Docker部署SpringBoot应用

3.1 打包

请参考使用Docker打包SpringBoot并Push到DockerHub文章中的打包.并对pom.xml和application-dev.yml、application-test.yml进行如下修改:

在pom.xml中添加如下内容:

<!--<properties>标签中-->
<spring-cloud.version>Greenwich.M3</spring-cloud.version>

<!--<dependencies>标签中-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-consul-discovery</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<dependency>
    <groupId>com.netflix.feign</groupId>
    <artifactId>feign-httpclient</artifactId>
    <version>8.18.0</version>
</dependency>

<!--与<dependencies>标签同级-->
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
<repositories>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

在application-dev.yml中添加如下内容:

spring:
  application:
    name: rest-api-mybatis
  cloud:
    consul:
      host: 127.0.0.1
      port: 8500
      discovery:
        register: true
        tags: urlprefix-/rest strip=/rest

3.2 启动

docker run --name rest_api --net=host -t star936/rest-api-mybatis:0.0.1

• -t参数: Docker打包应用的镜像名:tag

4. 验证

4.1 查看consul ui

访问http://localhost:8500,查看是否注册上服务,如下图所示:

4.2 请求

向 http://localhost:9999/rest/{controller的URL} 发送请求,如果返回数据,则表示成功.
