我有一个在 Docker 容器中运行的 Rails 应用程序。我通过docker-compose up.

我让它运行我的容器并附加调试器。

但是每当我分离调试器时，整个容器都会崩溃。（退出代码 1）

它能做什么：

  • 开始docker-compose up
    • backend_1 | Fast Debugger (ruby-debug-ide 0.7.2, debase 0.2.4.1, file filtering is supported) listens on 0.0.0.0:1234
  • 在 http://localhost:3000 无法访问应用程序（我必须先附加调试器）
  • 我附上一个调试器
  • 我分离调试器
  • 容器崩溃（
  • 我必须server.pid手动删除（添加类似的脚本rm /app/tmp/pids/server.pid && $other_command$）不起作用。

它会做什么：

  • 启动 docker-compose
  • 应用程序应通过 http://localhost:3000 运行并可用
  • 每当需要时，我都会附加一个调试器
  • 如果不再需要调试器，只需分离调试器
  • 容器继续运行

我必须做的总是：

  • 重新运行/重启容器
  • rm -rf /app/tmp/pids/server.pid
  • 重新连接调试器

这是我的设置：

DockerCompose

services:
  backend:
    ports:
      - 3000:3000 # disabled otherwise port 3000 AND 5000 are occupied. maybe it's a bug
      - 1234:1234
      - 26162:26162
    command: sh -c "rm -f /app/tmp/pids/server.pid && bin/bundle exec rdebug-ide --debug --host 0.0.0.0 --port 1234 -- bin/bundle exec bin/rails s -p 3000 -b '0.0.0.0'"

Dockerfile

.
..
...
COPY . /usr/src/app
EXPOSE 3000 1234 26162
CMD "rm -f /rails/tmp/pids/server.pid && bin/web"

启动.json

}

  • 我想我必须以某种方式调整 launch.json 或 docker-compose#command 。

  • 有人有想法吗？

  • 这是通常的情况，我必须在分离调试器后重新启动容器吗？
