上一篇聊到用兩個(gè)物理機(jī)（一個(gè)win,一個(gè)mac）來(lái)部署dapr和服務(wù) ，實(shí)現(xiàn)order調(diào)用pay的負(fù)載均衡。本篇說(shuō)一下在windows上的docker部署這三個(gè)服務(wù)，達(dá)到與上一篇的效果。

三個(gè)服務(wù)的部署架構(gòu)是這樣的

首先要把OrderSystem(服務(wù)端口80)項(xiàng)目docker化，Dockerfile內(nèi)容為：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base WORKDIR /app EXPOSE 80FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build WORKDIR /src COPY ["/OrderSystem/OrderSystem.csproj", "OrderSystem/"] RUN dotnet restore "OrderSystem/OrderSystem.csproj" COPY . . WORKDIR "/src/OrderSystem" RUN dotnet build "OrderSystem.csproj" -c Release -o /app/buildFROM build AS publish RUN dotnet publish "OrderSystem.csproj" -c Release -o /app/publishFROM base AS final WORKDIR /app COPY --from=publish /app/publish . ENTRYPOINT ["dotnet", "OrderSystem.dll"]

其實(shí)要把PaymentSystem(服務(wù)端口80)項(xiàng)目docker化，Dockerfile內(nèi)容為：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base WORKDIR /app EXPOSE 80FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build WORKDIR /src COPY ["/PaymentSystem/PaymentSystem.csproj", "PaymentSystem/"] RUN dotnet restore "PaymentSystem/PaymentSystem.csproj" COPY . . WORKDIR "/src/PaymentSystem" RUN dotnet build "PaymentSystem.csproj" -c Release -o /app/buildFROM build AS publish RUN dotnet publish "PaymentSystem.csproj" -c Release -o /app/publishFROM base AS final WORKDIR /app COPY --from=publish /app/publish . ENTRYPOINT ["dotnet", "PaymentSystem.dll"]

同時(shí)再添加一個(gè)docker-compose項(xiàng)目(右鍵 OrderSystem或PaymentSystem，Add，選擇Container Orchestrator Support即可)，命名為B2C，目錄結(jié)構(gòu)如下：

其中docker-compose.yml內(nèi)容如下

version: '3.4'services:ordersystem:image: ${DOCKER_REGISTRY-}ordersystembuild:context: ../dockerfile: /OrderSystem/Dockerfileports:- "3500:3500"volumes: - ../OrderSystem:/OrderSystem ordersystem-dapr:image: "daprio/daprd:latest"command: [ "./daprd", "-app-id", "order", "-app-port", "80" ]depends_on:- ordersystemnetwork_mode: "service:ordersystem"paymentsystem1:image: ${DOCKER_REGISTRY-}paymentsystembuild:context: ../dockerfile: /PaymentSystem/Dockerfileports:- "3601:3500"volumes: - ../PaymentSystem:/PaymentSystem paymentsystem1-dapr:image: "daprio/daprd:latest"command: [ "./daprd", "-app-id", "pay", "-app-port", "80" ]depends_on:- paymentsystem1network_mode: "service:paymentsystem1"paymentsystem2:image: ${DOCKER_REGISTRY-}paymentsystembuild:context: ../dockerfile: /PaymentSystem/Dockerfilevolumes: - ../PaymentSystem:/PaymentSystem ports:- "3602:3500"paymentsystem2-dapr:image: "daprio/daprd:latest"command: [ "./daprd", "-app-id", "pay", "-app-port", "80" ]depends_on:- paymentsystem2network_mode: "service:paymentsystem2"

為了使PaymentSystem部署多個(gè)副本，我在docker-compose.yml中配置了paymentsystem1和paymentsystem2，它們使用的都是PaymentSystem項(xiàng)目的信息。關(guān)于docker-compose就不多說(shuō)了。

進(jìn)入B2C目錄，啟動(dòng)三個(gè)服務(wù)，命令如下：

docker-compose?up?-d

就會(huì)在docker中啟動(dòng)三個(gè)服務(wù)，一個(gè)order，兩個(gè)pay，如下：

看一下結(jié)果吧，同樣是postman，輸入localhost:3500/v1.0/invoke/order/method/order，就會(huì)看到pay會(huì)輪詢調(diào)用。

paymentsystem1

paymentsystem1

總結(jié)
