在Windows Server 2019通过Docker Compose部署Asp.Net Core

2022-08-23 11:23:03

一、安装Docker Enterprise

安装文档是： https://docs.docker.com/install/windows/docker-ee/

安装完成后，如下图

二、首先，拉取一个Windows的镜像

这会将Microsoft的Nano Server Docker映像下载到您的环境中。该映像是最小的Windows服务器操作系统，打包后可作为Docker容器运行。您可以将其用作自己的应用程序的基础，也可以直接从中运行容器。

docker image pull mcr.microsoft.com/windows/nanoserver:1809

三、然后运行一个简单的容器测试

docker container run mcr.microsoft.com/windows/nanoserver:1809 hostname

这将从Windows Nano Server映像运行一个新容器，并告诉它运行hostname命令。输出是容器的机器名称，实际上是Docker设置的随机ID。重复该命令，您将每次看到一个不同的主机名。

四、将镜像推送到Docker Hub要先设置docker id（就是docker的账号）

设置docker id

$dockerId = ‘<your-docker-id>‘

五、测试生成DockerFile

Docker镜像是通过docker image build命令使用一个名为Dockerfile的简单脚本构建的。Dockerfile描述了应用程序及其所有依赖项的完整部署。

使用powershell生产DockerFile

‘FROM mcr.microsoft.com/windows/nanoserver:1809‘ | Set-Content Dockerfile
‘CMD echo Hello World!‘ | Add-Content Dockerfile

六、Build Image

现在运行docker image build，为图像提供一个标签，该标签使用您的Docker ID进行标识：

docker image build --tag $dockerId/hello-world .

注意：build后面的那个“.”是必须的。build的目录要是有权限的，最好是新建一个文件夹。不然就算能正确生产DockerFile也build不成功。猜测这里应该是没有管理员权限

七、运行容器

docker container run $dockerId/hello-world

八、推送镜像到Docker Hub

现在，有了一个用于简单Hello World应用程序的Docker映像。该映像是可移植单元-您可以将映像推送到Docker Hub，任何人都可以将其拉出并自己运行您的应用程序。

首先docker login使用您的凭据运行，以通过注册表进行身份验证。然后推送图像：

docker image push $dockerId/hello-world

没权限。。。先登陆

docker login -u 用户名 -p 密码

推送完了之后在我本地的windows上就可以看到如图

可以尝试本地拉取：

docker pull 13797054045/hello-world

九、使用Docker Compose部署

我拿了一个测试项目来做测试。先把项目通过git拉到了服务器上。

下载Docker Compose

Invoke-WebRequest https://github.com/docker/compose/releases/download/1.23.2/docker-compose-Windows-x86_64.exe -UseBasicParsing -OutFile $env:ProgramFiles\docker\docker-compose.exe

写DockerFile。我偷了个懒，通过VS自动生成的，然后修改的

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
WORKDIR /app
EXPOSE 8018  --我这里只改了端口

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY ["Gas.Monitoring.Web/Gas.Monitoring.Web.csproj", "Gas.Monitoring.Web/"]
COPY ["Gas.Monitoring.Business.Application/Gas.Monitoring.Business.Application.csproj", "Gas.Monitoring.Business.Application/"]
COPY ["Gas.Monitoring.Business.Repository/Gas.Monitoring.Business.Repository.csproj", "Gas.Monitoring.Business.Repository/"]
COPY ["ZB.Infrastructure.Base/ZB.Infrastructure.Base.csproj", "ZB.Infrastructure.Base/"]
COPY ["ZB.Infrastructure/ZB.Infrastructure.csproj", "ZB.Infrastructure/"]
COPY ["Gas.Monitoring.Business.Domain/Gas.Monitoring.Business.Domain.csproj", "Gas.Monitoring.Business.Domain/"]
COPY ["ZB.Infrastructure.FileSystem/ZB.Infrastructure.FileSystem.csproj", "ZB.Infrastructure.FileSystem/"]
COPY ["ProjectBuilder/ProjectBuilder.csproj", "ProjectBuilder/"]
COPY ["Gas.Monitoring.MP.Application/Gas.Monitoring.MP.Application.csproj", "Gas.Monitoring.MP.Application/"]
COPY ["Gas.Monitoring.MP.Repository/Gas.Monitoring.MP.Repository.csproj", "Gas.Monitoring.MP.Repository/"]
COPY ["Gas.Monitoring.MP.Domain/Gas.Monitoring.MP.Domain.csproj", "Gas.Monitoring.MP.Domain/"]
COPY ["ZB.UEditor.Core/ZB.UEditor.Core.csproj", "ZB.UEditor.Core/"]
RUN dotnet restore "Gas.Monitoring.Web/Gas.Monitoring.Web.csproj"
COPY . .
WORKDIR "/src/Gas.Monitoring.Web"
RUN dotnet build "Gas.Monitoring.Web.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "Gas.Monitoring.Web.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Gas.Monitoring.Web.dll"]

然后修改后。这里我改的时候碰了不少壁啊。还好都解决了。

FROM microsoft/dotnet:2.2-aspnetcore-runtime-nanoserver-1809 AS base
WORKDIR /biogas
EXPOSE 8018

FROM microsoft/dotnet:2.2-sdk-nanoserver-1809 AS build
WORKDIR /src
COPY ["Gas.Monitoring.Web/Gas.Monitoring.Web.csproj", "Gas.Monitoring.Web/"]
COPY ["Gas.Monitoring.Business.Application/Gas.Monitoring.Business.Application.csproj", "Gas.Monitoring.Business.Application/"]
COPY ["Gas.Monitoring.Business.Repository/Gas.Monitoring.Business.Repository.csproj", "Gas.Monitoring.Business.Repository/"]
COPY ["ZB.Infrastructure.Base/ZB.Infrastructure.Base.csproj", "ZB.Infrastructure.Base/"]
COPY ["ZB.Infrastructure/ZB.Infrastructure.csproj", "ZB.Infrastructure/"]
COPY ["Gas.Monitoring.Business.Domain/Gas.Monitoring.Business.Domain.csproj", "Gas.Monitoring.Business.Domain/"]
COPY ["ZB.Infrastructure.FileSystem/ZB.Infrastructure.FileSystem.csproj", "ZB.Infrastructure.FileSystem/"]
COPY ["ProjectBuilder/ProjectBuilder.csproj", "ProjectBuilder/"]
COPY ["Gas.Monitoring.MP.Application/Gas.Monitoring.MP.Application.csproj", "Gas.Monitoring.MP.Application/"]
COPY ["Gas.Monitoring.MP.Repository/Gas.Monitoring.MP.Repository.csproj", "Gas.Monitoring.MP.Repository/"]
COPY ["Gas.Monitoring.MP.Domain/Gas.Monitoring.MP.Domain.csproj", "Gas.Monitoring.MP.Domain/"]
COPY ["ZB.UEditor.Core/ZB.UEditor.Core.csproj", "ZB.UEditor.Core/"]
RUN dotnet restore "Gas.Monitoring.Web/Gas.Monitoring.Web.csproj"
COPY . .
WORKDIR "/src/Gas.Monitoring.Web"
RUN dotnet build "Gas.Monitoring.Web.csproj" -c Release -o /biogas/build

FROM build AS publish
RUN dotnet publish "Gas.Monitoring.Web.csproj" -c Release -o /biogas/publish

FROM base AS final
WORKDIR /biogas
COPY --from=publish /biogas/publish .
ENTRYPOINT ["dotnet", "Gas.Monitoring.Web.dll"]

这样改的好处是我服务器上是不用下任何环境的，.Net Core SDK和Runtime都在容器里面了。

然后，编写docker-compose.yml。因为我这里只有一个项目，比较简单。唯一要说的是空格要注意！！！

version: ‘3.4‘

services:
    biogas:
      image: biogas
      build:
        context: .
        dockerfile: Gas.Monitoring.Web/Dockerfile
      ports:
        - "8018:8018"

顺便贴一个多项目的

version: ‘3.4‘

services:
    yopm:
      image: yopm
      build:
        context: .
        dockerfile: YO.PM.Web/Dockerfile
      ports:
        - "8081:8081"

    yopmclub:
      image: yopmclub
      build:
        context: .
        dockerfile: YO.Clubs.Web/Dockerfile
      ports:
        - "8082:8082"

CD到你的项目目录执行命令
