Introduction

Setting up an OS to work with xhyve can be a bit tricky, but it's not impossible. These intructions should be generally applicable to most versions of Linux.

Create a disk image file

Xhyve will use a file as a logical disk. Be sure you have the filesize you need, because growing the file later is tricky to impossible (you could try to use qcow or similar to get around this, but qcow volumes can be tricky to mount).

dd if=/dev/zero of=hdd.img bs=1g count=32 # Create a 32 gig disk. Raise 'count' as desired

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

Go has excellent build tools that mitigate the need for using make. For example, go install won't update the target unless it's older than the source files.

However, a Makefile can be convenient for wrapping Go commands with specific build targets that simplify usage on the command line. Since most of the targets are "phony", it's up to you to weigh the pros and cons of having a dependency on make versus using a shell script. For the simplicity of being able to specify targets that can be chained and can take advantage of make's chained targets,

Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.
