Setup modern.ie vagrant boxes

Setup modern.ie vagrant boxes

Since modern.ie released vagrant boxes, it' no longer necessary to manually import the ova file to virtualbox, as mentioned here.

However, the guys at modern.ie didn't configured the box to work with WinRM. This how-to addresses that, presenting steps to proper repackage these boxes, adding WinRM support. Additionally configures chocolatey package manager and puppet provisioner.

FreeBSD on a MacBook Pro

FreeBSD on a MacBook Pro

Since 2008 or 2009 I work on Apple hardware and OS: back then I grew tired of Linux desktop (which is going to be MASSIVE NEXT YEAR, at least since 2001), and switched to something that Just Works. Six years later, it less and less Just Works, started turning into spyware and nagware, and doesn't need much less maintenance than Linux desktop — at least for my work, which is system administration and software development, probably it is better for the mythical End User person. Work needed to get software I need running is not less obscure than work I'd need to do on Linux or othe Unix-like system. I am finding myself turning away from GUI programs that I used to appreciate, and most of the time I use OSX to just run a terminal, Firefox, and Emacs. GUI that used to be nice and unintrusive, got annoying. Either I came full circle in the last 15 years of my computer usage, or the OSX experience degraded in last 5 years. Again, this is from a sysadmin/developer ki

How to compile nsinit for Docker to access a shell in a running container.

Docker nsinit

nsinit provides a handy way to access a shell inside a running container's namespace. This is useful for learning about how containers work, debugging your system without worrying about sshd daemons, and even hot fixes in production all you sad pandas!

:p

Running the docker daemon with the lxc driver allows you to use lxc-attach to do this. But now that docker deafults to the new native libcontainer driver, nsinit is probably the best way to go. jpetazzo's blog has a great high level summary.

The new issue is that the libcontainer .json format is under heavy development so you need to keep an nsinit binary built from the exact release tag from the the docker github repo. The tricky part for me was understanding that golang is designed with certain assumptions about dependencies vs versioning with regards to when you push to master, push to a topic branch, and fork a project.
