【问题描述】：

我无法使用自签名证书在 https 上为 asp.net core 3 api 运行 docker-compose。我已按照 ms docs 上的说明进行操作，但在尝试了数小时后我已经放弃了： https://docs.microsoft.com/en-us/aspnet/core/security/docker-https?view=aspnetcore-2.2

dotnet dev-certs https -ep %USERPROFILE%\.aspnet\https\aspnetapp.pfx -p { password here }
dotnet dev-certs https –trust

我的 docker compose 在这里：

version: '3.7'

networks:
  localdev:
    name: localdev

services:
  main-api:
    container_name: main-api
    build: 
      context: .
      dockerfile: Dockerfile
    #restart: always
    ports:
      - "5000:5000"
      - "5001:5001"

    depends_on:
      - db-server
    networks:
      - localdev

    volumes:
      - $USERPROFILE/.aspnet/https:/https/

    environment:
        ASPNETCORE_Kestrel__Certificates__Default__Password: "Passw0rd!"
        ASPNETCORE_Kestrel__Certificates__Default__Path: "$USERPROFILE/.aspnet/https/aspnetapp.pfx"

  db-server:
    image: mariadb:latest
    container_name: db-server
    environment:
      - MYSQL_ROOT_PASSWORD=Password! 
    ports: 
      - "13306:3306" 
    networks: 
      - localdev

docker-compose 日志在这里：

$ ls -l %USERPROFILE%\.aspnet\https\aspnetapp.pfx
-rw-r--r-- 1 tig28 197609 2652 Dec 17 23:07 %USERPROFILE%.aspnethttpsaspnetapp.pfx

使用 Linux 语法：

$ ls -l $USERPROFILE/.aspnet/https/aspnetapp.pfx
-rw-r--r-- 1 tig28 197609 2652 Dec 17 11:15 'C:\Users\tig28/.aspnet/https/aspnetapp.pfx'

【问题讨论】：

这和 docker-compose 有什么关系？
看看你是否在你的 Dockerfile 中使用 docker 命令得到同样的错误
ASPNETCORE_Kestrel__Certificates__Default__Path 应该只包含有效的文件路径。请从中删除无效部分。
如果我将路径更改为只有一个路径，我会得到相同的没有这样的文件：ASPNETCORE_Kestrel__Certificates__Default__Path: "%USERPROFILE%\\.aspnet\\https\\aspnetapp.pfx"
根据您上面粘贴的输出，您正在尝试构建 Linux Docker 映像，其中只有 Windows 的环境变量（例如 %USERPROFILE%）通常是无效的。

【解决方案1】：

对您的 docker-compose 文件进行微小更改，此处的路径将是容器 /root/.aspnet/https/ApiHost.pfx 的挂载路径。

environment:
  ASPNETCORE_HTTPS_PORT: 6001
  ASPNETCORE_ENVIRONMENT: Development
  ASPNETCORE_Kestrel__Certificates__Default__Path:/root/.aspnet/https/ApiHost.pfx
  ASPNETCORE_Kestrel__Certificates__Default__Password: <password>
volumes:
  - ${USERPROFILE}\.aspnet\https:/root/.aspnet/https

【解决方案2】：

如果您的项目使用 .net 6，则映射到卷的本地路径如下所示

参考：Hosting ASP.NET Core images with Docker Compose over HTTPS

dotnet dev-certs https -ep %USERPROFILE%\.aspnet\https\aspnetapp.pfx -p { password here }
dotnet dev-certs https --trust

version: '3.4'

services:
  webapp:
    image: mcr.microsoft.com/dotnet/core/samples:aspnetapp
    ports:
      - 80
      - 443
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
      - ASPNETCORE_Kestrel__Certificates__Default__Password=<password>
      - ASPNETCORE_Kestrel__Certificates__Default__Path=/https/aspnetapp.pfx
