Setup Docker with Vagrant

Get the vagrant-based docker env from DockerRoot Vagrant Box, which is tiny (only 12 MB) and contains the lastest version of docker (Linux kernel v4.1.6 and GLIBC, Docker v1.8.1). The direct download address is https://atlas.hashicorp.com/ailispaw/boxes/docker-root/versions/1.0.0/providers/virtualbox.box).

P.S. Some mini linux disto: Tiny Core Linux(on which boot2docker is based), yoctoproject, BusyBox, Buildroot.

Data-Only Container (Container-as-Volumn Pattern)

Tiny Docker Pieces, Loosely Joined:

Since I’ve spelled it out in such exhaustive detail, this may all seem like much ado about nothing…but, now that I finally grok the idea, I can see how data-only containers are so useful.

• It’s the simplest way to share data among multiple containers.
• It makes it easy to upgrade the application (or process) that operates on the data. For example, say we wanted to generate PDF files in addition to HTML files. All we need to do to accomplish that is to create an updated pandoc-convert Docker image.
• Adding additional processes that operate on the data is equally easy. What if you wanted to push the HTML files to an Amazon S3, in addition to serving them locally? Just create a new s3sync Docker image.
