I’ll admit right up front that this post is more “science experiment” than practical, everyday use case. It all started when I was trying some Cluster API-related stuff that leveraged KinD (Kubernetes in Docker). Obviously, given the name, KinD relies on Docker, and when running Docker on macOS you generally would use Docker Desktop. At the time, though, I was using Docker Machine, and as it turns out KinD doesn’t like Docker Machine. In this post, I’ll show you how to make KinD work with Docker Machine.
By the way, it’s worth noting that, per the KinD maintainers, this isn’t a tested configuration. Proceed at your own risk, and know that while this may work for some use cases it won’t necessarily work for all use cases.
These instructions assume you’ve already installed both KinD and Docker Machine, along with an associated virtualization solution. I’ll be using VirtualBox, but this should be largely the same for VMware Fusion or Parallels (or even HyperKit, if you somehow manage to get that working). I’m also assuming that you have jq installed; if not, get it here.

In these uncertain times we know the Internet is so much more than a tool. It’s a way for people to stay connected, informed, and educated. It shortens distances, spurs innovation, and fosters social and economic development. It empowers us and frees us.
It is a lifeline.
Yet, nearly 50% of the world still remains unconnected – and globally the Internet faces threats, each with the power to undermine the core of its existence. Now more than ever we must ensure the Internet remains open, globally connected, and secure.
The world is counting on it.
As we looked back at our work in 2019, an inspiring theme emerged: a global society driven by the idea that the Internet should be a resource for all, and persevering against odds to make this vision a reality. This society recognizes the Internet’s power as a way to stay in touch, to empower, to enable, and to create. Collectively, we are not just helping to bridge the digital divide, we are taking action to ensure the Internet remains resilient and trusted – a force for good.
Our 2019 Impact Report highlights the work of the Internet Society – our Chapters, Organization Members, individual members, Continue reading

This week, like many of you reading this article, I am working from home. I don’t know about you, but I’ve found it hard to stay focused when the Internet is full of news related to the coronavirus.
CNN. Twitter. Fox News. It doesn’t matter where you look, everyone is vying for your attention. It’s totally riveting…
… and it’s really hard not to get distracted.
It got me annoyed enough that I decided to do something about it. Using Cloudflare’s new product, Cloudflare Gateway, I removed all the online distractions I normally get snared by — at least during working hours.
This blog post isn’t very long, but that’s a function of how easy it is to get Gateway up and running!
To get started, you’ll want to set up Gateway under your Cloudflare account. Head to the Cloudflare for Teams dashboard to set it up for free (if you don’t already have a Cloudflare account, hit the ‘Sign up’ button beneath the login form).
If you are using Gateway for the first time, the dashboard will take you through an onboarding experience:
The onboarding flow will help you set up your first location. A location is Continue reading
To move ahead in your career and achieve the goals you set for yourself at the start of your career is going to involve taking some risks. However, not every risk you take in your career is a wise and healthy risk that will lead to the rewards you are seeking. Before you take any risk in your career, you first need to define healthy risk taking behavior.
Healthy risk taking behavior can be defined as risk taking that is planned and calculated after weighing the pros and cons of taking that risk. You can also define healthy risk taking behavior as taking a risk to reach your career goals, knowing that taking that risk can lead to failure, but can also lead to great success.
Risk taking helps you to overcome your fear and take action in the pursuit of a higher goal. When engaging in healthy risk taking, there are some things you need to consider.
What will be the possible outcomes of taking certain risks? For example, will changing from one company to another result in getting you a step closer to your career goals, or will the outcome Continue reading
In this week's IPv6 Buzz episode, Ed and Tom discuss deploying end-user wireless IPv6 with Charlie Clemmer, a principal network engineer with HPE/Aruba and regular WLPC presenter. We talk about how to get started, key tools and utilities to help with deployment, and more.

This may sound like a weird title, but hear me out. You’d think keepalives would always be helpful, but turns out reality isn’t always what you expect it to be. It really helps if you read Why does one NGINX worker take all the load? first. This post is an adaptation of a rather old post on Cloudflare’s internal blog, so not all details are exactly as they are in production today but the lessons are still valid.
This is a story about how we were seeing some complaints about sporadic latency spikes, made some unconventional changes, and were able to slash the 99.9th latency percentile by 4x!
I'm going to focus only on two parts of our edge stack: FL and SSL.
Here’s a diagram:
These days we route all traffic through SSL for simplicity, but in the grand scheme of things it’s not going to matter much.
Each of these processes is not itself a single process, but rather a master process and a collection of Continue reading
One of the first roadblocks you’ll hit in your “let’s master Ansible” journey will be a weird error deep inside a Jinja2 template. Can we manage that complexity somehow… or as one of the participants in our Building Network Automation Solutions online course asked:
Is there any recommendation/best practices on Jinja templates size and/or complexity, when is it time to split single template into function portions, what do you guys do? And what is better in terms of where to put logic - into jinja or playbooks
One of my friends described the challenge as “Debugging Ansible is one of the most terrible experiences one can endure…” and debugging Jinja2 errors within Ansible playbooks is even worse, but there are still a few things you can do.

This is an urgent call for expert help to quickly test a possible method to sterilize used N95 masks.
In many places, hospital staff, first responders and others are at grave risk due to inadequate supplies of N95 masks. Already, some hospitals even in the U.S. report running out of N95 masks and face reusing possibly contaminated masks. My local fire department has about 20 N95 masks total available, as they face transporting patients to the hospital. People are faced with reusing masks without sterilization. I offer an idea that might alleviate the critical shortage. I have run this idea past my pulmonary care doctor of many years who believes that the idea may be viable, but everyone on the front lines of the epidemic are already working flat out.
I sent the letter below to Dr. Anthony Fauci that sets the context.
People with the right expertise are needed to vet the idea and ensure that it is safe and effective as quickly as possible.
Dear Dr. Fauci,
N95 masks are in critically short supply. Sterilization of disposable masks N95 could be a Continue reading
