Scripts for setting up and maintaining my home lab

Usage

Getting this Repository

Download this repository:

sudo yum install -y git
git clone https://github.com/hogepodge/symmetrical-memory.git

stage 1: setup

To get started, use the scripts in the setup directory to set up a base CentOS 7 system. The first script updates your installation and reboots (acquiring a new kernel if necessary). It also stops and disables the firewall daemon.

The second script installs the base requirements, including the Docker service. It configures a local registry, and downloads and installs Kolla in a virtual environment.

The third script, to be run as root, builds a set of OpenStack deployment containers for Kolla and loads them into the local repository.

Assumptions:

  • You're running CentOS.
  • The fixed IP address of the target host is 192.168.1.6.
  • Registry storage is at a preconfigured directory named /registry.
  • You want to run the registry on port 4000 rather than 5000, because Keystone.

stage 2: standalone ironic with docker

The docker directory contains a set of scrips to build and install a small local standable Ironic service. Note that many assumptions about my home lab are build into the container configuration, so you will need to modify the files for your installation. Just run the scripts in order. To tear down an installation, use the uninstall.sh script.

This set of scripts assumes a CentOS 7 installation

Limitations

So many, just a few off the top of my head:

  • In its current state, the application is heavily programmed for my working environment. I'm working on fixing this and making it a more generally useful system that works by configuration rather than magic variables in code. Sorry about that.
  • I've only verified that this works with Ironic agent_ipmitool, rather than Ironic pxe_impitool. What's the difference? To over-simplify, iSCSI. I have not yet successfully booted an instance using the pxe_ipmitool (which uses iSCSI on the conductor to send images over) vs the agent_ipmitool (which pulls image data and writes it to disk). This is a work in progress that will sadly stay in progress for a while, as the agent_ipmitool get the job I need done, done.
  • Security? What security? If you want this to be the base for a real operations tool, you have some work ahead of you. I believe that you can do it.

Acknowledgments

This work leans heavily on the efforts of the OpenStack Bifrost team, particularly the work and advice of Julia Kreger. Many thanks for her support and patience as I learned to install and operate Ironic.

Also thanks to the OpenStack Kolla team for getting me started down this path of using containers for operations.

This will always be a work in progress, and I'll modify to fit whatever my immediate needs are. I'm grateful to everyone for the support they've given to me, and any mistakes I've made with this project or bugs I've encoded are all my own.

If you find this useful, and want to help improve or maintain it, I welcome any and all issues or pull requests.
