Upgrading Kubernetes Cluster with Kops, and Things to Watch Out For

Alright! I'd like to apologize for the inactivity for over a year. Very embarrassingly, I totally dropped the good habit. Anyways, today I'd like to share a not so advanced and much shorter walkthrough on how to upgrade Kubernetes with kops.

At Buffer, we host our own k8s (Kubernetes for short) cluster on AWS EC2 instances since we started our journey before AWS EKS. To do this effectively, we use kops. It's an amazing tool that manages pretty much all aspects of cluster management from creation, upgrade, updates and deletions. It never failed us.

How to start?

Okay, upgrading a cluster always makes people nervous, especially a production cluster. Trust me, I've been there! There is a saying, hope is not a strategy. So instead of hoping things will go smoothly, I always have bias that shit will hit the fan if you skip testing. Plus, good luck explaining to people

Building pgModeler in MacOS with Homebrew

The official installation instructions for pgModeler recommends installing Xcode and the Enterprise DB distribution of Postgres to fulfill its build requirements. Luckily, Homebrew's got us covered!

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Background

I believe Ubuntu 16.04 comes with PostgreSQL 9.5. Thats good for a start, but it is a matter of time before you have the need of a PostgreSQL 9.6 cluster. For me it was to import a PG backup from Heroku.

The procedure couldn't have been any easier and is described below. If you are interested in upgrading your old cluster to 9.6 afterwards, you may be interested in this.

Instructions

This gist has been moved to its own Github repo, so it's easier to contribute with additions and corrections. Please open a PR there if you see any mistake, I don't track comments on here as there's no notification system for gists AFAIK. Thanks.
