前面的微服务都是在本地环境下执行的，包括微服务、RabbitMQ、Consul、前端等，需要安装JDK、相关的服务器等，随着架构的发展，可能需要引入其他工具和服务，这些工具和服务有自己的安装过程，具体取决于操作系统及其版本。

总体而言，想在各种环境中运行后端系统，无论是什么OS版本，理想情况下，希望能受益于"一次构建，随处部署"策略，并避免在所部署系统的每种环境中重复执行所有配置和安装步骤，而且，部署尽可能简单。

原来，打包系统的一种方法是创建虚拟机（VM）。有几种创建和运行虚拟机的解决方案，称为虚拟机监控程序。其优点是一台管理机可以同时运行多个VM，共享硬件资源，每个VM都需要自己的操作系统，然后通过该监控程序将其连接到主机的CPU、RAM和硬盘等。

这个方案中，可以从Linux发行版开始创建一个VM，并在其中设置和安装运行系统所需的工作和服务：Consul、RabbitMQ、Java运行时、JAR应用程序等。一旦虚拟机正常工作，就可以将其转移到运行了虚拟机监控程序的其他任何计算机上。其层次结构如图所示：
虚拟机 Gateway Consul RabbitMQ Multiplication Gamification Logs Linux OS（安装了Java）虚拟机监控程序主机的操作系统
（如果运行裸机监控程序，则不需要）主机的硬件

但是，将所有程序放到一个虚拟机中并不灵活，如果要扩展，则必须进入虚拟机，添加新实例，并确保分配更多CPU、内存等，需要了解所有组件的工作原理，部署过程不再那么容易。

更动态的方法是为每个服务和工具配备独立的虚拟机，然后，添加一些网络配置，确保它们可以互相连接。由于使用服务发现和动态扩展，可以添加更多运行了微服务的虚拟机实例，并透明地使用。这些新实例只要使用其地址在Consul中注册即可。层次结构如图所示。这比单个VM更好，但考虑到每个虚拟机都需要自己的操作系统，会浪费大量资源，而且，在虚拟机编排方面带来很多挑战：监视、创建新实例、配置网络、存储等。

随着虚拟化技术的发展，虚拟机已经被废弃了，容器成为主流的应用程序虚拟化方式。因为容器不需要安装操作系统，体积要小得多，占用资源也更少。另外，像Docker这样的容器化平台大大简化了云和本地部署，并提供易于使用的工具来打包应用程序，将它们作为容器运行并在公共注册表中共享。

Docker

容器在业界存在很多年了，但Docker的流行使容器重焕光彩，因此许多容器的定义和观点都是从Docker的架构中产生的。Docker实在太流行了，以至于容器化也称为Docker化。Docker是一个基于Linux内核的、构建、传输和运行轻量级容器的平台。Docker默认支持Linux平台。借助在Virtual Box之上运行的Boot2Docker, Docker也支持Mac和Windows平台。亚马逊的EC2 Container Service（ECS）默认支持在AWS EC2实例上运行Docker。Docker可以安装在裸机上，也可以安装在传统的虚拟机上，比如VMWare或Hyper-V。

在Docker中，可将应用程序及其可能需要的任何支持组件打包为映像（image），这些映像可以基于从Docker注册表中提取的其他现有映像，可以重复使用并节省时间，映像的官方注册表是Docker Hub。例如，Multiplication微服务的映像可以基于JDK 21映像，然后，可在其上添加Spring Boot打包的JAR文件。要创建一个映像，需要编写一个Dockerfile文件，其中包含Docker CLI工具命令。Multiplication微服务的Dockerfile文件如下所示：

dockerfile 复制代码

FROM openjdk:21
COPY ./target/multiplication-0.0.1-SNAPSHOT.jar z:/_Docker/multiplication
WORKDIR z:/_Docker/multiplication
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "multiplication-0.0.1-SNAPSHOT.jar"]

这些命令告诉Docker使用官方映像opendjk的21版为基础，然后将可分发的.jar文件复制到文件夹z:/_Docker/multiplication，接着设置工作目录为拷贝到的目标文件夹z:/_Docker/multiplication，再使用EXPOSE开放8080端口来提供REST API访问，最后通过ENTRYPOINT运行命令，启动服务。

注意：这里使用Windows下的Docker，所以目录是Windows的访问方式，Linux下使用Docker更方便。

要构建映像，必须使用Docker CLI工具，该工具随标准Docker安装包一起提供，安装了Docker工具后，通常就可以使用。在使用Dockerfile文件构建映像时，有一个前提，就是要生成./target/multiplication-0.0.1-SNAPSHOT.jar文件，可以使用maven来生成，命令如：./mvnw clean package。有了基础，就可以执行构建命令了，过程如下所示：

bash 复制代码

使用docker images命令，就可以看到映像已经创建，如下所示：

bash 复制代码

> docker images
REPOSITORY                                             TAG          IMAGE ID       CREATED         SIZE
multiplication                                         1.0.0        ee8506662365   2 minutes ago   571MB
...

构建映像后，就可以在本地使用了，可将其作为容器运行，该容器是映像的运行实例，运行容器的命令如下所示：

bash 复制代码

> docker run -it -p 18080:8080 multiplication:1.0.0

如果本地镜像不可用，Docker的run命令会从服务器获取镜像（如果服务器存在该镜像）并运行。当容器执行时，这个容器无法正常执行，查看日志可以看到如下错误：

bash 复制代码

因为容器无法正常连接Consul和RabbitMQ，默认情况下，Spring Boot会与Consul一样尝试在localhost上查找RabbitMQ主机。在容器中，localhost指容器自己，而不是其他，要想正确设置后端系统在Docker中运行，必须将RabbitMQ和Consul部署为容器，并使用Docker网络将其连接起来，层次结构如图所示：
虚拟机容器 Logs 容器 RabbitMQ 容器 Consul 容器 Multiplication 容器 Gamification 容器 Gateway Docker 主机的操作系统
（如果运行裸机监控程序，则不需要）主机的硬件

下面就来看看Spring Boot如何构建Docker映像，这样就不需要自己创建Dockerfile了。

Spring Boot和Buildpacks

Spring Boot支持云原生的Buildpacks来构建Open Container Initiative（OCI）镜像，旨在帮助打包应用程序以将其部署到任何云提供商的项目，可在Docker和其他容器平台中运行生成的镜像。

Buildpacks插件可以基于项目的Maven配置准备一个计划，然后打包一个准备部署的Docker镜像，此外，以某种方式将镜像分层组织，以便未来的应用程序版本甚至使用该工具构建的其他微服务镜像（例如，包含所有Spring Boot核心库的层）都可以重用，有助于快速测试和部署。

如果从命令行运行build-image目标，就可以看到Buildpacks在执行：
./mvnw spring-boot:build-image

在Gamification项目文件夹下，执行上述命令，就可以看到相应的构建镜像的日志，如果一切顺利，可以在最后看到如下日志：

bash 复制代码

[INFO] Building image 'docker.io/library/gamification:0.0.1-SNAPSHOT'
...

Docker标记设置为pom.xml文件gamification:0.0.1-SNAPSHOT中指定的Maven工件的名称和版本，docker.io/library/是所有公共Docker镜像的默认值，也可以自定义选项。

可以像前面执行镜像一样运行容器，命令如下：

bash 复制代码

> docker run -it -p 18081:8081 gamification:0.0.1-SNAPSHOT

类似地，会出现相同的错误，应用程序无法连接到RabbitMQ和Consul，它们需要两种服务。

如果想完全控制要构建的内容以及要包含在镜像中的工具和文件，最后自定义Dockerfile命令，这并不难。

在Docker中运行系统

现在，将系统的每个组件构建或找到一个Docker镜像，以便进行容器化部署：

Multiplication、Gamification、Gateway和Logs微服务：将使用Spring Boot的Maven插件和Buildpacks来生成这些Docker镜像。
RabbitMQ：前面就已经使用Docker来部署了。
Consul：前面也采用了Docker的镜像来提供服务了。
前端：如果想在Docker中部署整个系统，还需要Web服务器来托管React构建生成的HTML/Javascript文件。可以使用Nginx这样的轻量级静态服务器，使用Docker官方镜像。

整个系统计划6个不同的Docker镜像并使用两个公共的Docker镜像，如下所示：
REST API调用
8000 获取HTML/JS
3000 Consul的
配置导入器 consul-importer:1.0
(based consul:1.11.1) 集中式日志 logs:0.0.1
(Buildpacks) Consul consul:1.11.1 RabbitMQ rabbitmq:3-
management Gamification gamification:0.0.1
(Buildpacks) Multiplication multiplication:0.0.1
(Buildpacks) 前端的Web服务器 challenge-frontend:1.0
(based on nginx:1.21.5) 网关 gateway:0.0.1
(Buildpacks) 浏览器

Docker化微服务

首先为Spring Boot应用程序构建所有镜像，在每个项目文件夹下执行以下命令：

bash 复制代码

> ./mvnw spring-boot:build-image

Docker化前端

在前端项目创建一个Dockerfile文件，只要两条命令，指定基本的nginx镜像，将build文件夹复制到容器目录下，如下所示：

bash 复制代码

FROM nginx:1.25.3
COPY build /usr/share/nginx/html

在创建Docker镜像前，先执行npm run build命令，编译React项目，生成build文件夹，就可以创建Docker镜像了，命令如下：

bash 复制代码

> docker build -t challenge-frontend:1.0 .

Docker化配置导入器

还需要一个Docker镜像来加载预定义的集中式配置，已经有一个运行服务器的Consul容器，通过运行一个额外的容器来执行Consul CLI来加载一些KV数据：一个Docker配置文件。这样，可以在Docker中运行微服务时使用预加载的配置文件配置，因为需要不同的RabbitMQ参数。

想要在文件中加载配置，可在本地Consul服务器中创建该配置，然后，通过CLI命令将其导出。使用UI创建config根目录，并创建一个名为defaults,docker的子文件夹。在内部，创建一个名为application.yml的键，其配置如下所示：

yml 复制代码

spring:
  rabbitmq:
    host: rabbitmq
  cloud:
    consul:
      discovery:
        instance-id: ${spring.application.name}-${random.int(1000)}

该配置执行如下操作：

将RabbitMQ主机设为rabbitmq，覆盖默认的localhost，要确保消息代理的容器在该地址可用。
覆盖分配给正在运行的服务的实例标识符，以在服务注册表中使用。默认的Spring Consul配置将应用程序名称与端口号连接在一起，该方法对容器无效。在Docker中运行同一服务的多个实例时，都使用相同的内部端口，因此会有相同的标识符。为解决这个问题，可使用随机数为后缀。

下图显示了Consul用户界面添加的配置：

然后将配置导出到文件，可在Consul终端执行如下命令：

bash 复制代码

> consul kv export config/ > consul-kv-docker.json

文件内容如下：

json 复制代码

[
        {
                "key": "config/",
                "flags": 0,
                "value": ""
        },
        {
                "key": "config/defaults,docker/application.yml",
                "flags": 0,
                "value": "c3ByaW5nOgogIHJhYmJpdG1xOgogICAgaG9zdDogcmFiYml0bXEKICBjbG91ZDoKICAgIGNvbnN1bDoKICAgICAgZGlzY292ZXJ5OgogICAgICAgIGluc3RhbmNlLWlkOiAke3NwcmluZy5hcHBsaWNhdGlvbi5uYW1lfS0ke3JhbmRvbS5pbnQoMTAwMCl9"
        }
]

现在，需要创建一个docker文件夹，存放Dockerfile文件，以及所导出的json配置，便于创建Docker镜像，Dockerfile如下：

Dockerfile 复制代码

FROM consul:1.11.1
COPY ./consul-kv-docker.json /usr/src/consul/
WORKDIR /usr/src/consul
ENV CONSUL_HTTP_ADDR=consul:8500
ENTRYPOINT until consul kv import @consul-kv-docker.json; do echo "正在启动 Consul"; sleep 2; done

这个镜像使用Consul为基础，将json文件复制到镜像内部，并将工作目录设置为与文件相同，然后，使用ENV命令设置环境变量，以使用远程主机访问服务器，这里是consul:8500，最后，是一个内联的shell脚本，遵循until ... done模式，直到运行命令成功为止，两次尝试之间的间隔为2秒，主命令是consul kv import @consul-kv-docker.json，将文件内容导入KV存储器，需要循环执行，因为此时，Consul服务器可能尚未启动。

现在，就可用构建容器了：

bash 复制代码

> docker build -t consul-importer:1.0 .

Docker Compose

构建完所有镜像后，需要将系统作为一组容器运行，下面就来看看然后启动这些容器并通信。

可使用单个Docker命令来启动所有必需的容器，并设置网络以使它们彼此连接，但是，如果要告诉其他人如何启动系统，需要向其传递包含所有这些命令和说明的脚本或文档。Docker有更好的方法可用对容器配置和部署指令进行分组：Docker Compose。

通过Compose，使用YAML文件来定义基于多个容器的应用程序，然后，使用命令docker-compose来运行所有服务。需要创建一个docker-compose.yml配置文件，下面给出了RabbitMQ和Consul的配置：

yaml 复制代码

version: "3"

services:
  consul-dev:
    image: consul:latest
    container_name: d_consul
    ports:
      - '8500:8500'
      - '8600:8600/udp'
    command: 'agent -dev -node=learnmicro -client=0.0.0.0 -log-level=INFO'
    networks:
      - microservices
  rabbitmq-dev:
    image: rabbitmq:management
    container_name: d_rabbitmq
    ports:
      - '5672:5672'
      - '15672:15672'
    networks:
      - microservices

networks:
  microservices:
    driver: bridge

这里定义了两个服务：consul-dev和rabbitmq-dev，可以用任何名称，-dev后缀，表明都在开发模式下运行（没有集群的独立节点）。这两个服务使用的是没有创建的Docker容器，使用Docker Hub中的公共镜像。container_name指定了容器名称，其他容器可以通过名称来找到它，这意味着应用程序可以使用地址d_rabbitmq:5672而不是默认的localhost:5672连接到RabbitMQ服务器。一旦指定了名称，就无法将服务扩展到多个容器了。

这里还定义了一个类型为bridge的网络，名称为microservices，驱动程序的类型为默认类型，用于连接独立的容器。然后，在每个服务定义中使用参数networks将microservices网络设置为可以访问的网络，这意味着这些服务可以互相连接，因为它们属于同一网络。Docker网络与主机网络是隔离的，除了使用ports参数显示公开的服务之外，无法访问任何服务。

现在，使用这个docker-compose.yml文件来运行Consul和RabbitMQ容器，需要执行命令：

bash 复制代码

> docker-compose up

Docker Compose会自动获取docker-compose.yml而不指定名称，这是默认文件名，所有容器的输出都会附加到当前终端和容器。如果要在后台将其作为守护进程，只需要在命令中添加-d标志即可。执行命令后，可以看到如下日志：

bash 复制代码

> docker-compose up

要停止Docker Compose的Docker容器，执行如下命令：

bash 复制代码

> docker-compose down -v
[+] Running 3/3
 ✔ Container d_rabbitmq          Removed                                                                           6.4s
 ✔ Container d_consul            Removed                                                                           0.3s
 ✔ Network docker_microservices  Removed                                                                           0.2s

下一步将配置加载到Consul KV中，进行修改docker-compose.yml文件：

yml 复制代码

version: "3"

services:
  consul-importer:
    image: consul-importer:1.0
    depends_on:
      - consul-dev
    networks:
      - microservices
  consul-dev:
    # ...
  rabbitmq-dev:
    # ...

networks:
  microservices:
    driver: bridge

这里利用前面构建的consul-importer:1.0镜像来进行Consul KV存储的导入，使用参数depends_on在compose文件中建立依赖关系，让它在consul-dev容器之后启动。无论如何，不能保证consul-importer运行时Consul服务器已经就绪。原因是Docker只知道容器何时启动，不知道Consul服务器何时启动并准备接受请求，这是要在导入程序镜像中添加脚本的原因，该脚本会重试导入，直到导入成功为止。

当再次运行docker-compose up时，会看到相应的输出，加载了配置并成功退出，如下所示：

bash 复制代码

> docker-compose up
...
consul-importer-1  | Imported: config
consul-importer-1  | Imported: config/defaults,docker/application.yml
consul             | 2023-12-31T00:47:17.155Z [INFO]  agent: Synced node info
consul             | 2023-12-31T00:47:17.273Z [INFO]  agent.server: federation state anti-entropy synced
consul-importer-1 exited with code 0
...

consul-importer容器是作为函数而不是连续运行的服务，这里使用简单地加载配置然后完成的命令替换了Consul镜像中的默认命令，命令在Dockerfile中定义，将服务器作为进程运行，Docker知道命令已退出，容器无事可做，因此不必保持容器处于活动状态。

还可以查看docker-compose配置中正在运行的容器是哪些，可使用docker-compose ps命令，如下所示：

bash 复制代码

> docker-compose ps
NAME         IMAGE                 COMMAND                  SERVICE        CREATED          STATUS          PORTS
consul       consul:1.11.1         "docker-entrypoint.s..."   consul-dev     18 minutes ago   Up 18 minutes   8300-8302/tcp, 8600/tcp, 8301-8302/udp, 0.0.0.0:8500->8500/tcp, 0.0.0.0:8600->8600/udp
d_rabbitmq   rabbitmq:management   "docker-entrypoint.s..."   rabbitmq-dev   18 minutes ago   Up 18 minutes   4369/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, 15671/tcp, 15691-15692/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp

使用浏览器访问http://localhost:8500/，就可以进入Consul界面，导航到KV选项卡，就可以看到config条目，进一步可以看到已加载的配置，如下所示：

接着向Docker Compose中添加前端定义，只需要添加基于Nginx构建的镜像，并公开重定向到内部端口的端口3000，默认情况下基本镜像的端口为80，可以更改公开的端口，但要相应地调整Gateway中的CORS配置，docker-compose.yml添加如下：

yml 复制代码

version: "3"

services:
  frontend:
    image: challenge-frontend:1.0
    ports:
      - '3000:80'
  consul-importer:
    # ...
  consul-dev:
    # ...
  rabbitmq-dev:
    # ...

networks:
  microservices:
    driver: bridge

为了使整个系统正常运行，需要将Spring Boot微服务添加到Docker Compose文件中，将它们配置为使用之前创建的同一网络，这些容器都需要到达consul和d_rabbitmq容器才能正常工作，有两种不同的策略：

对于Consul设置，Spring中的集中式配置功能要求服务在引导阶段知道服务器所在的位置。需要覆盖属性spring.cloud.consul.host，将其指向consul容器，这可以通过环境变量来实现，在Spring Boot中，如果设置的环境变量与现有属性匹配或遵循某种命名约定，将覆盖本地配置。
对于RabbitMQ配置，将使用docker配置文件。假设微服务连接到Consul，并且配置服务器具有defaults,docker的一个预加载条目，那么它们都将使用其中的属性。要注意，在配置文件中RabbitMQ主机改为了d_rabbitmq了。要激活每个微服务中的docker配置文件，使用Spring Boot属性来通过环境变量SPRING_PROFILES_ACTIVE=docker来传递。

另外，在compose中配置Spring Boot容器时需要注意：

不在localhost:8000上将后端服务直接公开给主机（Gateway服务除外），因此，不会将ports部分添加到Multiplication、Gamification和Logs服务中。
对后端容器使用depends_on参数，以等待consul-importer运行，因此，在Spring Boot应用程序启动时，docker配置的Consul配置将可用。
将rabbitmq作为这些服务的依赖项，但这不能保证RabbitMQ服务器在应用程序启动前就已准备就绪，但Spring Boot默认情况下会重试连接到服务器，系统最终将会稳定。

完整的配置如下：

现在就可用测试完整的Docker部署系统了，运行docker-compose up命令，就可以在输出中看到许多日志，这些日志由启动的多个服务生成。可能会看到，某些后端服务在尝试连接到RabbitMQ时会抛出异常，这是预期的情况，因为RabbitMQ服务启动需要更长的时间，在rabbitmq服务启动就绪后，将恢复正常。

可能还会遇到没有足够的内存或CPU来同时运行所有容器而产生的错误，这不是异常，因为每个微服务容器最多可以占用1GB的RAM。

要了解系统状态，可以使用Docker提供的聚合日志（附加输出）或logs容器的输出。可以从终端使用另一个docker-compose logs [container_name]来查看对应的日志，下面就是检查logs日志的输出：

bash 复制代码

> docker-compose logs logs

现在Consul中检查服务，可以看到运行状况检查是否通过，这意味着服务已经运行并连接到RabbitMQ了，如下所示：

点击一项服务（如multiplication），可以看到docker网络中容器的地址，如图所示：

使用浏览器访问http://localhost:3000/，就可以使用应用程序了，如下所示：

数据持久化，应该考虑添加卷来存储数据库文件。

使用Docker扩展系统

使用docker compose，还可以使用单个命令来扩展服务。

首先，启动系统（docker-compose up），然后，从另一个终端再次运行带有scale参数的命令，指出服务名称和希望获取的实例数，可在单个命令中多次使用scale参数，如下所示：

bash 复制代码

> docker-compose up --scale multiplication=2 --scale gamification=2

现在，查看终端日志，就可以看到Docker Compose为multiplication和gamification服务启动了额外的实例，也可以在Consul服务中看到，如下所示：

从Consul中可以看到其中的变化，借助Consul发现、网关模式、Spring Cloud负载均衡器和RabbitMQ消费者的负载均衡，系统会再次在多个实例之间适当地负载均衡，可使用HTTPie命令来进行尝试：

bash 复制代码

> http POST :8000/attempts factorA=50 factorB=60 userAlias=noise10 guess=3000

在日志中可以看到实例如何处理来自API的请求，如下所示：

bash 复制代码

共享Docker镜像

目前为止，所有镜像都存储在本地计算机中，这不能实现"一次构建，随处部署"的策略。

Docker Hub是一个公共注册表，从中下载的RabbitMQ和Consul官方镜像，以及微服务的基础镜像。如果在这里上传自己的镜像，每个人就都可以使用了。

关于如何使用Docker Hub上传镜像，这里不再介绍，感兴趣的请自己查找相关资料。

小结

文章介绍了Docker容器化技术，有助于将微服务部署到多个环境中；简述了Spring Boot应用程序如何构建Docker镜像，并使用Docker Compose实现对Docker容器集群的快速编排，这样使多个容器相互配合来完成整个应用系统，可以轻松、高效的管理容器，提高效率。
