Bootstrapping Servers into Ansible
As part of a lab rebuild I’ve been doing over the last few weeks (funny how hardware failures can lead to a lab rebuild), I’ve been expanding the use of Ansible for configuration automation. In this post, I’m going to share the process I’ve created for bootstrapping newly-built servers into Ansible.
I developed this Ansible bootstrapping process to work in conjunction with the fully automated Ubuntu installation method that I described in an earlier post. The idea is that I would be able to boot a new server (virtual or physical), choose a configuration from the PXE menu, and a few minutes later have a built Ubuntu system. Then, with a single command, I could “bootstrap” the server into an Ansible configuration automation system. This latter part—configuring systems to work with Ansible—is what I’ll be describing here.
First, a (very) brief overview of Ansible. Ansible is a configuration automation tool that leverages standard SSH connections to remote devices in order to perform its work. Ansible is agentless, so no software has to be pre-installed on the managed servers, but this means Ansible has to authenticate against remote systems in order to establish these SSH connections. This authentication should, in ideal Continue reading
