问题

I am creating container app than uses a Docker container.

> ASPNETCORE_ENVIRONMENT="Staging"

我正在创建一个容器应用程序,它使用一个Docker容器。

ASPNETCORE_ENVIRONMENT="Staging"

I figured I could reference this docker environment file with --env-file dockerfile-staging.conf

我想我可以使用 --env-file dockerfile-staging.conf 来引用这个Docker环境文件。

"Docker": {
"commandName": "Docker",
"launchBrowser": true,
"launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}/swagger",
"DockerfileRunArguments": "--env-file dockerfile-staging.conf",
"publishAllPorts": true,
"useSSL": true
}

The environment variable ASPNETCORE_ENVIRONMENT is not set and by default is Development.

环境变量 ASPNETCORE_ENVIRONMENT 未设置,默认为 Development。

I do not see any errors.

我没有看到任何错误。

If I use the following the aspnetcore environment variable is set as Staging correctly.

如果我使用以下内容,则 aspnetcore 环境变量将正确设置为 Staging。

"DockerfileRunArguments": "-e ASPNETCORE_ENVIRONMENT=Staging"

  "publishAllPorts": true,
  "useSSL": true
}

Any Idea why may be wrong?

"DockerfileRunArguments": "-e ASPNETCORE_ENVIRONMENT=Staging",

--env-file dockerfile-staging.conf 没有生效,因为 VS 在 docker run 中传递了 -e ASPNETCORE_ENVIRONMENT=Development,而 Docker 优先使用命令行中的值。使用 -e 的原因是相同的。

作为替代方案,您可以使用以下方式:

"Docker": {
  "commandName": "Docker",
  "launchBrowser": true,
  "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}/swagger",
  "publishAllPorts": true,
  "useSSL": true,
  "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Staging"
  }
}

environmentVariables 中的值仅适用于该进程,因此即使在容器工具窗口中看不到该值,您也会在您的进程中看到它。

英文:

--env-file dockerfile-staging.conf isn't working b/c VS is passing -e ASPNETCORE_ENVIRONMENT=Development as part of the docker run and docker prioritizes the value from the command line over that in the env file. Using -e is working for the same reason.

As an alternative you can use:

"Docker": {
  "commandName": "Docker",
  "launchBrowser": true,
  "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}/swagger",
  "publishAllPorts": true,
  "useSSL": true,
  "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Staging"
  }
}

The values in environmentVariables are set for just the process, so even if you don't see the value in the container tools window, you will see it in your process.
