This time around, the content is a bit heavier on cloud management and applications/operating systems, but still lots of good content all the way around (I hope, anyway). First, here’s a workaround to the fact that vCA doesn’t (yet) do cloud-init, which makes injecting SSH keys into Linux instances a bit difficult. Networking.
