Minimal DevStack VirtualBox setup

This is a very concise quickstart guide to setup an OpenStack DevStack limited to Keystone in a VirtualBox VM using Ubuntu Server LTS as the guest operating system. By limiting the DevStack to primarily deploy Keystone only, installation is quick and the machine does not take up much resources.

As the time of writing it uses up about 11 GB of disk space and 1 GB of RAM running Keystone.

This is meant for testing authentication and IDM-related things with OpenStack Keystone while disregarding other components. It can easily be extended by further components by adjusting the local.conf accordingly.

MinIO w/ MinIO's certgen, as a S3 backup target for Harvester

MinIO and MinIO's certgen

There are a lot of ways to set up a MinIO Server depending on the need. As a quick example this just demonstrates an ability for MinIO to be running the server as a single executable binary downloaded from MinIO's site, as well as continuing to use MinIO's open source suite with the great little self-signed TLS cert tool called certgen. Then how to leverage both elements with Harvester as an S3 backup target.

My discord was lagging increasingly during long calls on my Manjaro installation. I searched a bit on the Wiki but the fix shared there didn't work for. What worked for me is this answer on the Discord support forum, that I will detail a bit here. Start by moving to the right folder:

cd ~/.config/discord/<your_version>/modules/discord_desktop_core

Then, depending on whether you are a javascript developer or not, you may need to install the npm package of your distribution. On Arch/Manjaro, yay -S npm will do. Once this is done, unpack the core.asar file with

npx asar extract core.asar core

	This is kinda a pain, the SSL part was hard to get down / understand.
	(it took forever troubleshooting

	The Binary of both Minio & Certgen is probably the easiest to work with.
	x86-64, from minio
	- certgen: https://github.com/minio/certgen

	The loadout will have:
	- single drive leveraged as a folder for storage since that's common place
	- SSL outta the box, since that's ABSOLUTELY NEEDED when building custom RKE2 clusters that have backups created... plainly, we can't have minio without SSL if we're planning to use MinIO for RKE2 Backups...
