Welcome to haconiwa - the (m)Ruby on Container

In the current tech scene, many developers use so-called Container-based virtualization such as Docker or LXC.

The speaker will talk about Linux container technologies and his tools. He develops haconiwa (, a tool helping developers combine container features such as cgroup, namespaces and capabilities which they want to use.

The speaker has about 2 years experiences on Docker (in-house CI basis) and LXC (PaaS service). The talk has background of (some) issues found in these experiences, and includes why he's creating a new container in Ruby and why he switched to *m*ruby.
