For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

CoreOS mdadm RAID1 for ROOT

• Setup SoftwareRAID for the CoreOS root partition without data-loss.
• Only for ext4!
• The Trick is to use the right volume label and fs-types :)
• We assume CoreOS is on /dev/sdaX and the second RAID Device is /dev/sdb
• Drawback: only / gets mirrored, Node goes down when sda fails

1. Boot into any recovery system like Grml
2. If not already done: install CoreOS

# Usage ./k8s-service-account-kubeconfig.sh ( namespace ) ( service account name )

TEMPDIR=$( mktemp -d )

trap "{ rm -rf $TEMPDIR ; exit 255; }" EXIT

SA_SECRET=$( kubectl get sa -n $1 $2 -o jsonpath='{.secrets[0].name}' )

AnnoyingTechnology

I was ready to throw it away, I opened it up and didn't find anything wrong with it. After a quick Google Search, turns out Apple fucked up their users (again) and locked this drive to only one laptop : the MacBook Air.

Bellow is the tweak (found online) to make it usable on Linux

# Debian/linux only - Linux SCSI generic driver
sudo apt install sg3-utils -y

Force recent MacOS to listen for screen sharing on localhost only, keeping SIP on

All the following has been validated on MacOS Mojave 10.14.6

Problems

While there is a command line preference to accept only local VNC connections, that setting still doesn't prevent the daemon from listening to the wildcard address, and advertise the service on Bonjour. I haven't actually tried to see if it restricted anything in modern versions of the operating system, but here it is for reference:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement.plist VNCOnlyLocalConnections -bool yes

How to push tagged Docker releases to Google Artifact Registry with a GitHub Action

Here's how I configured a GitHub Action so that a new version issued by GitHub's release interface will build a Dockerfile, tag it with the version number and upload it to Google Artifact Registry.

Before you attempt the steps below, you need the following:

• A GitHub repository that contains a working Dockerfile
• The Google Cloud SDK tool gcloud installed and authenticated
