Docker v1.1.2 and a presentation

If you’re upgrading from Docker v1 on a Mac, there’s now a formal Docker installer. But if you’ve previously used Brew like me, I would ensure you do:-

boot2docker stop
boot2docker delete
brew unlink docker
brew unlink boot2docker

before installing, otherwise you’ll end up with a bunch of EOF messages when you use the Docker command.

I had trouble with the latest CentOS base image (‘centos:latest’) – it doesn’t play nice and won’t install OpenJDK7-jdk because of a dependency on system.d which doesn’t want to install. Use Ubuntu or use ‘centos:centos6’ as your base image. I updated my GitHub repository to reflect this.

And finally, here’s my Coffee and Code presentation which I presented to colleagues – Intro to Docker.
