docker.io 0.8.1+dfsg1-1 (armhf binary) in ubuntu trusty

 Docker complements LXC with a high-level API which operates at the process
 level. It runs unix processes with strong guarantees of isolation and
 repeatability across servers.
 Docker is a great building block for automating distributed systems:
 large-scale web deployments, database clusters, continuous deployment systems,
 private PaaS, service-oriented architectures, etc.
 .
 This package contains the daemon and client. Using docker.io on non-amd64
 hosts is not supported at this time. Please be careful when using it on
 anything besides amd64.
 .
 Also, note that kernel version 3.8 or above is required for proper operation of
 the daemon process, and that any lower versions may have subtle and/or glaring
 issues.
