[`tinc`][1] is a Virtual Private Network (VPN) daemon that uses tunnelling and
encryption to create a secure private network between hosts on the Internet.

This tiny image (6.74 MB) is based on `alpine` (5.254 MB).
To use this image, you need to:

- Have baisc knowledges of tinc
- Create a directory tree by hand ([tutor][2])
- Use `docker-compose` to manage

## directory tree
