Running Unifi Controller in systemd-nspawn with cloud-init

This uses Ubuntu's server cloud image as a stateless container to run the UBNT Unifi Controller software. Configuration data is stored in a directory outside the container. Cloud-init is used to automatically set up the container image, so a new version can be dropped in with minimal effort. This should work with pretty much any modern Linux distro with systemd.

Setup

Systemd-nspawn prefers to store its machines on btrfs, so if your /var/lib/machines is not currently btrfs, you should create one and mount it there. Otherwise it will automatically create an image file at /var/lib/machines.raw and mount it.

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

A boring function (6:22)

func boring(msg string) {

    fmt.Println(msg, i)

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	// Just before switching jobs:
	// Add one of these.
	// Preferably into the same commit where you do a large merge.

	// This started as a tweet with a joke of "C++ pro-tip: #define private public",
	// and then it quickly escalated into more and more evil suggestions.
	// I've tried to capture interesting suggestions here.
