Question

我正在学习gcloud应用程序部署的学习过程。我一直在努力从以下位置运行.net HelloWorld示例代码：

https://github.com/GoogleCloudPlatform/dotnet-docs-samples/tree/master/appengine/flexible/HelloWorld

当我使用Visual Studio启动该示例时，该示例在桌面上运行良好。但是，我无法超越从cmd窗口使用“ gcloud app deploy”运行。以下是两次运行的详细信息，首先是即用型，第二个是在添加doocker文件之后。

还有其他人能够像当前版本的gcloud sdk一样运行HelloWorld示例吗？

感谢您的帮助，

鲍勃

这是gcloud版本信息：

gcloud --version
Google Cloud SDK 299.0.0
bq 2.0.58
core 2020.06.26
gsutil 4.51

经过一番搜索，我发现了一个建议，以改用自定义运行时和一个docker文件。因此，我做了两个更改，一个在app.yaml文件中，然后添加了docker文件。

这是app.yaml文件。

runtime: custom
env: flex

# This sample incurs costs to run on the App Engine flexible environment. 
# The settings below are to reduce costs during testing and are not appropriate
# for production use. For more information, see:
# https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml
manual_scaling:
  instances: 1
resources:
  cpu: 1
  memory_gb: 4
  disk_size_gb: 10

env_variables:
  # The __ in My__Greeting will be translated to a : by ASP.NET.
  My__Greeting: Hello AppEngine!

readiness_check:
  app_start_timeout_sec: 600

这是Dockerfile。该文件来自以下位置：

https://github.com/dotnet/dotnet-docker/blob/50e95cd9af6458ce0db21e6ec952e29c3ee1fadf/2.1/aspnet/alpine3.10/amd64/Dockerfile

ARG REPO=mcr.microsoft.com/dotnet/core/runtime-deps
FROM $REPO:2.1-alpine3.10

# Install ASP.NET Core
ENV ASPNETCORE_VERSION 2.1.15

RUN wget -O aspnetcore.tar.gz https://dotnetcli.azureedge.net/dotnet/aspnetcore/Runtime/$ASPNETCORE_VERSION/aspnetcore-runtime-$ASPNETCORE_VERSION-linux-musl-x64.tar.gz \

    && echo "$aspnetcore_sha512  aspnetcore.tar.gz" | sha512sum -c - \
    && mkdir -p /usr/share/dotnet \
    && tar -zxf aspnetcore.tar.gz -C /usr/share/dotnet \
    && rm aspnetcore.tar.gz \
    && ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet

这是使用docker文件运行的结尾。

Answer 1

好的，我熟悉Google Cloud Platform，但现在（不）熟悉.NET。

我正在使用Linux（！）和Cloud Shell：

gcloud alpha cloud-shell ssh

我克隆了存储库，但没有其他更改。

我能够在本地运行项目并进行测试：

dotnet run

，然后从另一个shell：

curl localhost:8080
Hello World!

注意，该状态尚未声明（也许很明显），但是您必须dotnet run（最好是dotnet publish）来创建./bin/Debug目录。

我创建了一个项目，设置了帐单，创建了一个应用引擎应用程序：

PROJECT="[[YOUR-PROJECT-ID]]"
BILLING="[[YOUR-BILLING-ID]]"
REGION="[[YOUR-REGION]]"

gcloud projects create ${PROJECT}
gcloud beta billing projects link ${PROJECT} --billing-account=${BILLING}
gcloud app create --project=${PROJECT} --region=${REGION}

然后，根据文档：

dotnet publish

./bin/Debug/netcoreapp2.1/publish的内容：

     56 Jul  6 16:23 appsettings.json
    544 Jul  6 16:23 app.yaml
 223992 Jul  6 16:27 HelloWorld.deps.json
   8192 Jul  6 16:27 HelloWorld.dll
   1708 Jul  6 16:27 HelloWorld.pdb
    213 Jul  6 16:27 HelloWorld.runtimeconfig.json
    516 Jul  6 16:30 web.config

注意包含app.yaml和HelloWorld.deps.json

然后：

gcloud app deploy ./bin/Debug/netcoreapp2.1/publish/app.yaml \
--project=${PROJECT}

并且：

ENDPOINT=$(\
  gcloud app describe \
  --project=${PROJECT} \
  --format="value(defaultHostname)")

curl ${ENDPOINT}
Hello AppEngine!

然后，在./appengine/flexible/HelloWorld目录中，创建Dockerfile：

FROM mcr.microsoft.com/dotnet/core/sdk:2.1 AS builder
WORKDIR /source

COPY *.sln .
COPY *.csproj .
RUN dotnet restore

COPY . .
RUN dotnet publish -c release -o /app --no-restore

FROM mcr.microsoft.com/dotnet/core/aspnet:2.1
WORKDIR /app
COPY --from=builder /app ./
ENTRYPOINT ["dotnet", "HelloWorld.dll"]

注意，以this为指南。

注意我降级为2.1（而不是3.1）以避免dotnet构建错误，但这是由于我对运行时不熟悉。

我更改了Program.cs，以强制使用:8080：

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseUrls("http://0.0.0.0:8080")
        .Build();
}

我修改了app.yaml以使用自定义运行时：

runtime: custom
env: flex

然后：

gcloud app deploy --project=${PROJECT}

工作。
