Docker-撰写未能读取 Docker 文件

Question

从昨天 (01.12.) 开始，我的 compose 遇到了一个奇怪的问题，我的 docker-compose 无法读取 Docker 文件。这个问题突然出现，因为代码没有改变，但构建开始失败。

我的docker-撰写：

service1:
image: service1-image
build:
  context: ${SERVICE1_DIR}
  dockerfile: \src\Service1.Service\Service1.Service.Web\Dockerfile-Development
ports:
  - "${HTTP_SERVICE1_PORT}:80"
  - "${HTTPS_SERVICE1_PORT}:443"
environment:
  - ASPNETCORE_ENVIRONMENT=Development
  - ASPNETCORE_URLS=https://+;http://+
  - ASPNETCORE_HTTPS_PORT=${HTTPS_SERVICE1_PORT}
  - ASPNETCORE_ConnectionStrings__SQLServer=Server=sqlserver;Database=Service1;User ID=sa;Password=****
  - ASPNETCORE_Kestrel__Certificates__Default__Password=${CERT_PASSWORD}
  - ASPNETCORE_Kestrel__Certificates__Default__Path=${SERVICE1_CERT_PATH}
volumes:
  - ${DOCKER_DIR}\https:/https/:ro

Dockerfile-Development 本身没有问题，因为我可以使用 docker build 命令直接构建映像。另外，如果我将其更改为 Dockerfile，错误是相同的。

SERVICE1_DIR is the path to the root of the folder (solution) and then I am extending the path to dockerfile which is located where my Web API project is. There are a couple of Class Library project on which my API has a dependency on. All of which I am referencing in my dockerfile without any issue.

我的环境：

docker-合成文件版本：3.4
docker 版本：Docker 版本 20.10.11，build dea9396

我正在使用 .NET SDK 6.0 和 ASPNET 6.0 运行时。

这是错误：

** 更新解决方案 **

解决了在 build

中将路径的缺失部分添加到 dockerfile 的问题

工作docker-撰写文件：

service1:
    image: service1-image
    build:
      context: ${SERVICE1_DIR}
      dockerfile: ${SERVICE1_DIR}\src\Service1.Service\Service1.Service.Web\Dockerfile-Development
    ports:
      - "${HTTP_SERVICE1_PORT}:80"
      - "${HTTPS_SERVICE1_PORT}:443"
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+;http://+
      - ASPNETCORE_HTTPS_PORT=${HTTPS_SERVICE1_PORT}
      - ASPNETCORE_ConnectionStrings__SQLServer=Server=sqlserver;Database=Service1;User ID=sa;Password=****
      - ASPNETCORE_Kestrel__Certificates__Default__Password=${CERT_PASSWORD}
      - ASPNETCORE_Kestrel__Certificates__Default__Path=${SERVICE1_CERT_PATH}
    volumes:
      - ${DOCKER_DIR}\https:/https/:ro

在你的 docker-compose.yaml 中你有 dockerfile 和 \src\Service1.Service\Service1.Service.Web\Dockerfile-Development 这是 Windows 解析为 C:\src... 的绝对路径.除非您的应用程序在此目录中，否则 docker-compose.yaml 中的 dockerfile 路径是不正确的，应该是相对于 docker-compose.yaml 的。可能 ${SERVICE1_DIR}\Service1.Service.Web\Dockerfile-Development 或类似。
