无法使用 Visual Studio 2017 调试我的 Docker 容器

Question

我无法使用 Visual Studio 2017 调试我的 Docker 容器。

我正在使用 Docker 18.06.1-ce 和 VS 15.8.8。

在 VS (control + F5) 中启动调试会话时，容器启动正常，但未附加 VS。容器也保持运行并且没有以dev 模式启动。如果我想杀死它，我必须使用docker stop a76244870ffe。

运行docker container ls:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
a76244870ffe        myapplication       "dotnet MyApplicat.."    25 minutes ago      Up 4 minutes        0.0.0.0:80->80/tcp   dockercompose10819768170563966978_myapplicatio_1

docker-compose.yml:

version: '3.4'

services:
  myapplication:
    image: ${DOCKER_REGISTRY}myapplication
    build:
      context: .
      dockerfile: dockerfile
    ports:
     - "80:80"
    environment:
     - ASPNETCORE_ENVIRONMENT=local

在 VS 中构建输出：

Answer 1

将Solution Configuration 设置为调试并按<CTRL + F5> 构建您的docker image 并在本地运行。

点击<F5>开始调试。

Answer 2

Ctrl + F5 是在没有调试器的情况下启动的快捷方式。尝试不带 Ctrl 的 F5。
