• in order to run keycloak in a docker container, run the below command:

docker run -p 8080:8080 -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=admin quay.io/keycloak/keycloak:latest start-dev

Overview

This is just a simple script that I use to generate self-signed certificates. It's suited for general use of course, however it also includes v3 extensions which are required for container registries like Quay. This is my "easy button" for PoCs that can use temporary self-signed certificates.

Useage

1. Download the script

   curl -L https://gist.githubusercontent.com/v1k0d3n/08b9a1d37a06e90ff39646e1b09417d8/raw/certgen.sh -o certgen.sh
   

2. Make it executable

You may run into an issue (at some point) where your directories are "insucure" either through a homebrew install or update. If this happens, you can do the following to fix the issue correctly, wihtout setting compinit to ignore errors (which I've seen recommended in some forums).

Example:

Last login: $D $MO $H:$M%S on $TTYS

[WARNING]: Console output during zsh initialization detected.

When using Powerlevel10k with instant prompt, console output during zsh
initialization may indicate issues.

NOTE: These proceedures are only for OpenShift SNO-Deployments. I will create a loop command later for multi-node environments.

❯ oc get pods -n openshift-etcd | grep etcd
etcd-itamae                4/4     Running     20         8d

ETCD_SNO_ENDPOINT=$(oc get pods -n openshift-etcd | grep etcd | awk '{print $1}')
echo $ETCD_SNO_ENDPOINT

Methods of Signing with a GPG Key on MacOS

Last updated September 21, 2022

This Gist explains how to do this using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

There has been a number of comments on this gist regarding some issues around the pinentry-program and M1 Macs. I've finally gotten a chance to try things out on an M1 and I've updated the documentation in 2-using-gpg.md to reflect my findings.
