#Namespaces are intended for use in environments with many users spread across multiple teams, or projects. For clusters with a few to tens of users, you should not need to create or think about namespaces at all. Start using namespaces when you need the features they provide.
#Namespaces provide a scope for names. Names of resources need to be unique within a namespace, but not across namespaces.
#Namespaces are a way to divide cluster resources between multiple uses (via resource quota).
#In future versions of Kubernetes, objects in the same namespace will have the same access control policies by default.
#It is not necessary to use multiple namespaces just to separate slightly different resources, such as different versions of the same software: use labels to distinguish resources within the same namespace.

About

recvtty is a reference implementation of a consumer of runC's --console-socket API. It is automatically built when doing a make on the runc project.

Prereq

These instructions were tested on Ubuntu 16.04. Also go, git are required.

Install runC

go get github.com/opencontainers/runc
cd $GOPATH/src/github.com/opencontainers/runc
