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

Kubernetes clusters using preemtible instances

Motivation

People experimenting with kubernetes clusters on the GKE not necessarily have money to keep a full cluster on at all time. GKE clusters can be easily resized, but this still incurs in the full instance cost when the cluster is up.

Google has added preemptible instances that are ideal for many

Requirements

no upfront installation/agents on remote/slave machines - ssh should be enough
application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
configuration templating
environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
deployment process run from Jenkins

Solution

How to implement a custom search for Hugo usig Gruntjs and Lunrjs.

Requirements

Setup

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

How to setup your own CA with OpenSSL

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

First things first

Lets get some context first.
