Getting Started with Cluster API using Docker
Cluster API (CAPI) is a relatively new project aimed at deploying Kubernetes clusters using a declarative API (think YAML). The official documentation (a.k.a. the Cluster API book), does a very good job explaining the main concepts and goals of the project. I always find that one of the best ways to explore new technology is to see how it works locally, on my laptop, and Cluster API has a special “Docker” infrastructure provider (CAPD) specifically for that. However, the official documentation for how to setup a docker managed cluster is very poor and fractured. In this post, I’ll try to demonstrate the complete journey to deploy a single CAPI-managed k8s cluster and provide some explanation of what happens behind the scene so that its easier to troubleshoot when things go wrong.
Prerequisites
Two things must be pre-installed before we can start building our test clusters:
- kind - a tool to setup k8s clusters in docker containers, it will be used as a management (a.k.a. bootstrap) cluster.
- clusterctl - a command line tool to interact with the management cluster.
We’re gonna need run a few scripts from the Cluster API Github repo, so let’s get a copy Continue reading

Our Work to Make the Internet for Everyone Marches On
Over the past several months the Internet Society has been working on a transaction to sell Public Interest Registry (PIR), operator of .ORG and other top-level domains, to Ethos Capital. Under PIR’s registry agreements, the Internet Corporation for Assigned Names and Numbers (ICANN) had to consent to this indirect change of control. ICANN has now announced that it does not consent to the transaction.
I am, of course, disappointed by ICANN’s decision, though I am pleased it was finally reached. ICANN took much longer than it should have done to vote on the transaction. In my view, ICANN stepped outside its remit by acting as a regulator it was never intended to be. What began as a routine change of indirect control – the type ICANN has expeditiously approved on multiple occasions in the past – resulted in months and months of review and analysis. The outcome does not seem consistent with ICANN’s prior decisions in similar cases. It should concern the Internet community that ICANN has shown itself to be much more susceptible to political pressure than its limited mandate would recommend.
Nevertheless, ICANN has now rendered a clear decision. This brings to a close a period Continue reading

Failure Is Fine, Learning Is Mandatory
“Failure is a harsh teacher because it gives the test first and the lesson afterward.” — Vernon Law
I’m seeing a thread going around on Twitter today that is encouraging people to share their stories of failure in their career. Maybe it was a time they created a security hole in a huge application. Perhaps it was creating a routing loop in a global corporation. Or maybe it was something as simple as getting confused about two mailboxes and deleting the wrong one and realizing your mail platform doesn’t have undelete functionality.
We fail all the time. We try our hardest and whatever happens isn’t what we want. Some of those that fail just give up and assume that juggling isn’t for them or that they can never do a handstand. Others keep persevering through the pain and challenge and eventually succeed because they learn what they need to know in order to complete their tasks. Failure is common.
What is different is how we process the learning. Some people repeat the same mistakes over and over again because they never learn from them. In a professional setting, toggling the wrong switch when you create someone’s new account has Continue reading

Now Is Not the Time to Put Everyone’s Security on the Line
This opinion piece was originally published in SC Magazine.
With social distancing the norm, we’re spending more time on the Internet doing more important things than ever – eg, working, learning, banking, trading, shopping, seeing the doctor and having family time – as well as streaming, gaming and interacting with our connected speakers.
Shouldn’t we be certain, especially now, that no one is eavesdropping, stealing or modifying our data?
Encryption is the primary means of accomplishing that goal. Using encryption, data is scrambled so that only the intended people can see the data. It’s right there under the covers most of the time when you’re on Wi-Fi, Bluetooth, 4G and browsing most websites.
Unfortunately, most online services today still do encryption in a piecemeal manner. Sections along the path are encrypted, but typically there are points along the way where the data is unencrypted and processed in some way before being re-encrypted and sent along.
The good news is that many messaging services – eg, WhatsApp, Telegram and Signal – offer end-to-end encryption, where only the sender and intended recipient can “see” the message. Everyone else along the path – even the company providing the service – can’t see inside. The Continue reading
