Making it Easier to Get Started with Cluster API on AWS

I’ve written a few articles about Cluster API (you can see a list of the articles here), but even though I strive to make my articles easy to understand and easy to follow along many of those articles make an implicit assumption: that readers are perhaps already somewhat familiar with Linux, Docker, tools like kind, and perhaps even Kubernetes. Today I was thinking, “What about folks who are new to this? What can I do to make it easier?” In this post, I’ll talk about the first idea I had: creating a “bootstrapper” AMI that enables new users to quickly and easily jump into the Cluster API Quick Start.

Normally, in order to use the Quick Start, there are some prerequisites that are needed first (these are all clearly listed on the Quick Start page):

• You need kubectl installed
• You need kind (which in turn requires Docker) or an existing Kubernetes cluster up and running

For Linux users (like myself), these prerequisites are pretty easy/simple to handle. But what if you’re a Windows or Mac user? Yes, you could use Docker Desktop and then install kind (or use docker-machine, if you’re feeling adventurous). Then you’d Continue reading

The Pursuit Of Storage That Spans The Clouds

Every IT supplier has cloudy envy. And not just because utility-style pricing has become normalized by the big public clouds, but because they want to have a more regular, annuity-like revenue stream rather than always chasing the next deal. …

How To Manage Docker Hub Organizations and Teams

Docker Hub has two major constructs to help with managing users access to your repository images. Organizations and Teams. Organizations are a collection of Teams and Teams are a collection of DockerIDs.

There are a variety of ways of configuring your Teams within your Organization. In this blog post we’ll use a fictitious software company named Stark Industries which has a couple of development teams. One which works on the front-end of the application and the other that works on the back-end of the application. They also have a QA team and a DevOps team. 

We’ll want to set up our Teams so that each engineering team can push and pull the images that they create. We’ll give the DevOps team access privileges to pull images from the dev teams repos and the ability to push images to the repos that they own. We’ll also give the QA team read-only access to all the repos.

Organizations

In Docker Hub, an organization is a collection of teams. Image repositories can be created at the organization level. We are also able to configure notifications and link to source code repositories.

Let’s set up our Organization.

NTC – Security and Networking

The increased rate of change in networking isn’t just impacting the operational models used to run networks. Network security posture, infrastructure, and operations are having to adapt quickly as well. In this episode we sit down with Henry Jiang, CISO of Diligent Corporation, to talk about how security is adapting to current infrastructure trends.

High Availability Load Balancers with Maglev

Background

We run many backend services that power our customer dashboard, APIs, and features available at our edge. We own and operate physical infrastructure for our backend services. We need an effective way to route arbitrary TCP and UDP traffic between services and also from outside these data centers.

Previously, all traffic for these backend services would pass through several layers of stateful TCP proxies and NATs before reaching an available instance. This solution worked for several years, but as we grew it caused our service and operations teams many issues. Our service teams needed to deal with drops of availability, and our operations teams had much toil when needing to do maintenance on load balancer servers.

Goals

With the experience with our stateful TCP proxy and NAT solutions in mind, we had several goals for a replacement load balancing service, while remaining on our own infrastructure:

1. Preserve source IPs through routing decisions to destination servers. This allows us to support servers that require client IP addresses as part of their operation, without workarounds such as X-Forwarded-For headers or the PROXY TCP extension.
2. Support an architecture where backends are located across many racks and subnets. This prevents solutions that cannot Continue reading

How Should Network Architects Deal with Network Automation

A network architect friend of mine sent me a series of questions trying to figure out how he should approach network automation, and how deep he should go.

There is so much focus right now on network automation, but it’s difficult for me to know how to apply it, and how it all makes sense from an Architect’s PoV.

A network architect should be the bridge between the customer requirements and the underlying technologies, which (in my opinion) means he has to have a good grasp of both as opposed to fluffy opinions glanced from vendor white papers, or brushed off so-called thought leaders.

MANRS Fellowship Program Now Open

The first-ever MANRS (Mutually Agreed Norms for Routing Security) Fellowship Program is now accepting applications. If you are an emerging leader eager to improve the well-being of the Internet’s global routing system, apply now.

The program gives highly motivated individuals the chance to work alongside MANRS ambassadors, who are industry leaders participating in the Ambassador Program. Together, they will train diverse communities on good routing practices, analyze routing incidents, research into ways to secure routing, and survey the global policy landscape.

Fellows will improve their skills and bring new perspectives and ideas to MANRS. They will also gain valuable insights and networking opportunities from well-respected professionals called MANRS Ambassadors under the MANRS Ambassadors Program. The selection process for this program is currently underway.

The Internet Society supports this program as part of its work to reduce common routing threats and establish norms for network operations.

You can apply for a fellowship in three different areas: training, research, and policy. Each fellow will receive a stipend of $750 a month. There is no age requirement and you can apply for more than one category but will only be selected for one of them.

Creating a Multi-AZ NAT Gateway with Pulumi

I recently had a need to test a configuration involving the use of a single NAT Gateway servicing multiple private subnets across multiple availability zones (AZs) within a single VPC. While there are notable caveats with such a design (see the “Caveats” section at the bottom of this article), it could make sense in some use cases. In this post, I’ll show you how I used TypeScript with Pulumi to automate the creation of this design.

For the most part, if you’re familiar with Pulumi and using TypeScript with Pulumi, this will be pretty straightforward. The code I’ll show you makes a couple assumptions:

1. It assumes you’ve already created the VPC and the subnets earlier in the code. I’ll reference the VPC object as vpc.
2. I’ll assume you’ve already created subnets in said VPC, and that the subnet-to-AZ ratio is 1:1 (exactly one subnet of each type—public or private—in each AZ). The code will reference the subnet IDs as pubSubnetIds (for public subnets) or privSubnetIds (for private subnets). (How to create the subnets and capture the list of IDs is left as an exercise for the reader. If you’d be interested in seeing how I do it, let me know. Continue reading
