When working with potentially dangerous, unverified, or simply raw software, developers often use sandboxes. These are special environments that isolate or restrict programs and code from accessing data outside the environment. Sandboxes limit the software’s network access, OS interactions, and information from IO devices.
Lately, people have been turning more and more towards containers for launching unverified and non-secure software. Read more
Today we’ll be continuing our containerization blog series with a discussion about runC, a tool for launching containers according to Open Container Initiative (OCI) specifications. The initiative’s mission is to develop a single standard for containerization technology and is supported by such companies as Facebook, Google, Microsoft, Oracle, EMC, and Docker. The OCI Runtime Specifications were published in the summer of 2015.
Modern containerization tools already implement runC. The latest versions of Docker (starting with version 1.11) have been made according to OCI specifications and are built on runC. The libcontainer library, which is essentially a part of runC, has replaced LXC in Docker as of version 1.8.
In this article, we’ll show you how you can create and manage containers using runC.

These operating systems are useful for managing a large number of applications in containers and for using different container clustering systems, like Kubernetes, Docker Swarm, Apache Mesos, etc.
