Playing with kubectl output

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

HOWTO Lightroom sync with s3 windows/macos

HOWTO Lightroom sync with s3 windows/macos

1. The pitch

As I am an avid photographer & travelling quite a lot, I wanted to sync my Adobe Lightroom library from Macbook to my Microsoft Windows desktop at home with very little/no human intervention. It is also a good thing that both Lightroom versions (mac & windows) share a common file system/structure, this helped alot in synchronizing data from one environment to another.

This HOWTO assumes you already have an AWS account created and running with an IAM user configured.

Put together, the solution would look as such (pardon my poor diagram skills):

                                  _  
macbook pro                     (`  ).                     windows desktop
