Greenfield Rancher install

Pre-Rancher Steps

Kubernetes Persistent Storage

Head to your synology/freenas and setup a new NFS share just for your kubernetes persistent storage. Make sure to turn off authentication.

Networking - Create a vlan just for your VMs

Create a vlan (10.0.X.1 or 192.168.X.1) just for your VMs in your Unifi Controller, dont worry about firewall or traffic shaping. What I typically do is once I have created the vlan, I go to the Unifi Switch configuration area, and assign the port that the server is being plugged-into as being mapped to my VM-VLAN.
Create a vlan for your Ingress Controller/Metallb. Just create the vlan and we'll worry about the rest later.

Building oc-cli for ARM Architectures

ARM64/AARCH64 (Jetson Nano) or RPi 4

cd $GOPATH

sudo apt install libgpgme-dev -y 
mkdir -p src/github.com/openshift
mv origin src/github.com/openshift/

Jetson Nano Cheatsheet

Below are my personal notes related to the Nvidia Jetson Nano Dev-board.

Performance Management

Nvidia allows your to fine tune the performance of your Jetson nano. More on this here.
