Я пытаюсь смонтировать каталог хоста в контейнер Docker, чтобы любые обновления, сделанные на хосте, отражались в контейнерах Docker. Я не смог добиться успеха после поиска в Google и чтения ссылок на тома Docker.

Где я делаю что-то не так. Вот что я сделал:

kishore$ cat Dockerfile<p></p>

<pre><code>FROM ubuntu:trusty
RUN apt-get update
RUN apt-get -y install git curl vim
CMD ["/bin/bash"]
WORKDIR /test_container
VOLUME ["/test_container"]
</code></pre>

kishore$ tree
.
├── Dockerfile
└── main_folder
    ├── tfile1.txt
    ├── tfile2.txt
    ├── tfile3.txt
    └── tfile4.txt<p></p>

1 directory, 5 files
kishore$ pwd
/Users/kishore/tdock
kishore$ docker build --tag=k3_s3:latest .<p></p>

I don't know how to check boot2docker version


Questions, issues facing:


How do I need to link the main_folder to the test_container folder present inside the docker container?
I need to make this automatically. How do I to do that without really using the run -d -v command?
What happens if the boot2docker crashes? Where are the Docker files stored (apart from Dockerfile)?
