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 #mermaid-svg-umLaLgpTmVOoIQYy {font-family:"trebuchet

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 ServiceECS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
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 docker build -t multiplication:1.0.0 .

...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 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

Spring Boot和Buildpacks
Spring Boot支持云原生的Buildpacks来构建Open Container InitiativeOCI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
[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 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 #mermaid-svg-ZTHAWJqzkUMDCeTw {font-family:"trebuchet ms",verdana,arial,sans-serif;font-size:16px;fill:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .error-icon{fill:#552222;}#mermaid-svg-ZTHAWJqzkUMDCeTw .error-text{fill:#552222;stroke:#552222;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edge-thickness-normal{stroke-width:2px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edge-thickness-thick{stroke-width:3.5px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edge-pattern-solid{stroke-dasharray:0;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edge-pattern-dashed{stroke-dasharray:3;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edge-pattern-dotted{stroke-dasharray:2;}#mermaid-svg-ZTHAWJqzkUMDCeTw .marker{fill:#333333;stroke:#333333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .marker.cross{stroke:#333333;}#mermaid-svg-ZTHAWJqzkUMDCeTw svg{font-family:"trebuchet ms",verdana,arial,sans-serif;font-size:16px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .label{font-family:"trebuchet ms",verdana,arial,sans-serif;color:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .cluster-label text{fill:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .cluster-label span{color:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .label text,#mermaid-svg-ZTHAWJqzkUMDCeTw span{fill:#333;color:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .node rect,#mermaid-svg-ZTHAWJqzkUMDCeTw .node circle,#mermaid-svg-ZTHAWJqzkUMDCeTw .node ellipse,#mermaid-svg-ZTHAWJqzkUMDCeTw .node polygon,#mermaid-svg-ZTHAWJqzkUMDCeTw .node path{fill:#ECECFF;stroke:#9370DB;stroke-width:1px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .node .label{text-align:center;}#mermaid-svg-ZTHAWJqzkUMDCeTw .node.clickable{cursor:pointer;}#mermaid-svg-ZTHAWJqzkUMDCeTw .arrowheadPath{fill:#333333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edgePath .path{stroke:#333333;stroke-width:2.0px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .flowchart-link{stroke:#333333;fill:none;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edgeLabel{background-color:#e8e8e8;text-align:center;}#mermaid-svg-ZTHAWJqzkUMDCeTw .edgeLabel rect{opacity:0.5;background-color:#e8e8e8;fill:#e8e8e8;}#mermaid-svg-ZTHAWJqzkUMDCeTw .cluster rect{fill:#ffffde;stroke:#aaaa33;stroke-width:1px;}#mermaid-svg-ZTHAWJqzkUMDCeTw .cluster text{fill:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw .cluster span{color:#333;}#mermaid-svg-ZTHAWJqzkUMDCeTw div.mermaidTooltip{position:absolute;text-align:center;max-width:200px;padding:2px;font-family:"trebuchet ms",verdana,arial,sans-serif;font-size:12px;background:hsl(80, 100%, 96.2745098039%);border:1px solid #aaaa33;border-radius:2px;pointer-events:none;z-index:100;}#mermaid-svg-ZTHAWJqzkUMDCeTw :root{--mermaid-font-family:"trebuchet ms",verdana,arial,sans-serif;} REST API调用8000 获取HTML/JS3000 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 ./mvnw spring-boot:build-imageDocker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
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 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
spring:rabbitmq:host: rabbitmqcloud: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 consul kv export config/ consul-kv-docker.json文件内容如下
[{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
FROM consul:1.11.1
COPY ./consul-kv-docker.json /usr/src/consul/

ENV CONSUL_HTTP_ADDRconsul: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 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
version: 3services:consul-dev:image: consul:latestcontainer_name: d_consulports:- 8500:8500- 8600:8600/udpcommand: agent -dev -nodelearnmicro -client0.0.0.0 -log-levelINFOnetworks:- microservicesrabbitmq-dev:image: rabbitmq:managementcontainer_name: d_rabbitmqports:- 5672:5672- 15672:15672networks:- microservicesnetworks: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 docker-compose upDocker 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 docker-compose up

[] 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
version: 3services:consul-importer:image: consul-importer:1.0depends_on:- consul-devnetworks:- microservicesconsul-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 docker-compose up
...

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 docker-compose ps

version: 3services:frontend:image: challenge-frontend:1.0ports:- 3000:80consul-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_ACTIVEdocker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

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。
