Easy way to upgrade Docker

by Andreas Mosti

If you use a system with a strickt package repository (like Debian stable, CentOS, RedHat etc.) chances are new releases of Docker won't be pushed right after release. A sweet trick I use on my CentOS machines is to just wget down the new binary like so: 

    service docker stop
    wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O /usr/bin/docker
    service docker start

Since Docker has released with quite a steady pace (and I like latest and greatest) I have eaven made an alias for the job - 

    alias getLatestDockerBinary='sudo wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O /usr/bin/docker'

Hope this might help somebody save time in the future.
