Day-2 Operations in OKE

Now that we have our cluster up and running we can start deploying whatever we want to it!

There are a few more things to be aware of if you’re trying to avoid spending any money on the cluster, which I’ll lay out in this article. Most of these are based on things I ran into myself when I first built my cluster, so there’s a chance you might discover surprises that won’t be covered here. I’ll assume you have a basic knowledge of core Kubernetes concepts wherever they come into play.

This is the 2nd part of our series on running a completely free multi-node Kubernetes cluster in Oracle Cloud. If you haven’t already read Part 1 I’d recommend starting there.

Summary

We’ve successfully created an Oracle Cloud (OCI) account and upgraded it to Pay-As-You-Go billing to remove any limitations on what we’re able to use. Now we get to move onto the fun part of actually building something.

I often see people asking for advice on how to get hands-on practice with Kubernetes in a cloud environment, but understandably, they don’t want to spend much money. While it’s true that the long-term cheapest way to run K8s is on a spare computer at home, there are also some shortcomings - upgrades can be trickier, autoscaling is next to impossible, if you want to access your cluster from the public internet you might not want to expose your home network’s public IP address (or might not know how to do so securely), and many more. Also, if your goal in doing this is to get a job in DevOps or SRE you might want to work with cloud-hosted services alongside your Kubernetes cluster.

About Me

Mon, 01 Jan 0001 00:00:00 +0000

I’ve been working in Tech in some form or another since 2014 when I got my start as a Systems Administrator. I started learning about Cloud and DevOps technologies on my own and was immediately excited by their possibilities for solving interesting technical problems. I’ve worked in a wide variety of industries including non-profit, venture capital, cloud consulting, online sportsbetting, and consumer startups.

When I’m not working or playing with technology I enjoy traveling, cooking, getting outdoors with my wife and our dog, playing video games, and checking out breweries wherever I happen to be.
