This example shows how to generate something like a random password and keeping it consistent during upgrades.
IF YOU CAN, you should let helm generate a random secret during every upgrade and update the app to rotate the password from old one to new one. There are many options available by means of jobs and hooks to figure this out.
Create a new helm chart with with no templates.

Mac OS uses LibreSSL. Getting OpenSSL can be done with brew:
brew install openssl
After which, an alias can be used for openssl commands:
ls -lah $(echo /opt/homebrew/Cellar/openssl@*/*/bin/openssl)
alias openssl=/opt/homebrew/Cellar/openssl@1.1/1.1.1s/bin/openssl

Some notes for Microstack that I expanded upon from https://gist.github.com/meetmatt/da9e7364dec04a43465e20c430fb58df and https://connection.rnascimento.com/2021/03/08/openstack-single-node-microstack/
These notes were compiled from a fresh installation on Ubuntu 20.04. The resulting Openstack installation is really just good for local development.
The network was on Google Wifi pucks. There is some additional notes about how to handle accessing the Openstack network in the routes section
My network network details are as follows.
- Gateway
192.168.86.1 - Subnet
192.168.86.0/24 - Host IP
192.168.86.152 -
- This was through DHCP and will cause problems if the computer ever loses it's lease.

User accounts are a part of the user.openshift.io group. The kinds available are
groups / group
identities / identity
users / user
useridentitymappings / useridentitymapping
Users have identities mapped directly on the user CR. The useridentitymapping CR seems to be just API related.
This is a script I wrote to automatically restart godoc whenever Go code is updated on my Macbooks. It is stored at ~/bin/godoc and ~/bin/ is a part of my Linux path.
