Multi-arch build, what about CircleCI?

Following the previous article where we saw how to build multi arch images using GitHub Actions, we will now show how to do the same thing using another CI. In this article, we’ll consider CircleCI, which is one of the most used CI SaaS.

To start building your image with CircleCI, you will first need to create .circleci/config.yml file:

version: 2
jobs:
  build:
    docker:
      - image: docker:stable
    steps:
      - checkout
      - setup_remote_docker:
          version: 18.09.3
      - run: docker version

You may notice that we specified using version 18.09.3 of the Docker Engine because buildx requires version 18.09 or later but CircleCI doesn’t provide any version above 18.09.3.

At this point we are able to interact with the Docker CLI but we don’t yet have the buildx plugin installed. To install it, we will download a build from GitHub.

version: 2
jobs:
  build:
    docker:
      - image: docker:stable
    steps:
      - checkout
      - setup_remote_docker:
          version: 18.09.3

Interesting: Measuring End-to-End Latency in Web Browser

CloudFlare launched yet another service: transfer speed- and latency measurements done from a web browser. While it’s pretty obvious how you could measure transfer speed (start an asynchronous transfer, register for the JavaScript onreadystatechange event to notice out when it has completed, and compute the transfer rate), measuring latency seems like a bit of black magic. After all, you can’t do a ping from a web browser, can you?

VMware Announces Intent to Acquire Lastline

By Tom Gillis, SVP and GM, Networking and Security Business Unit, VMware

EDITORIAL UPDATE: On June 18, 2020 VMware officially closed its acquisition of Lastline. The blog post below has been amended to reflect that announcement.

VMware announced its intent to acquire Lastline, a pioneer in anti-malware research and AI-powered network detection and response, and on June 18, 2020 the acquisition closed. This is an important step forward for VMware’s vision of Intrinsic Security, as it allows us to further take advantage of the intrinsic attributes of our virtualization platform to yield innovative security capabilities. Our aim is not to replicate that which exists today, but rather to build security solutions that we can uniquely deliver, spanning from the heart of the data center to users in a branch office and all the way to mobile users at home or on the road.

In the security industry, the nature of threats changes so rapidly that security technology is constantly being re-invented. In this context, it is not the algorithms per se that matter; it is the people that make the algorithms. Great people build great products, and great products build great companies. And that’s why we are so Continue reading

Enabling IPv6 in AWS Deployments

IPv6 is old enough to buy its own beer (in US, not just in Europe), but there are still tons of naysayers explaining how hard it is to deploy. That’s probably true if you’re forced to work with decades-old boxes, or if you handcrafted your environment with a gazillion clicks in a fancy GUI, but if you used Terraform to deploy your application in AWS, it’s as hard as adding a few extra lines in your configuration files.

Nadeem Lughmani did a great job documenting the exact changes needed to get IPv6 working in AWS VPC, including adjusting the IPv6 routing tables, and security groups. Enjoy ;)

Stack Overflow Survey Reconfirms Developer Love for Docker

The 2020 Stack Overflow Developer Survey confirms what we already knew: there’s a lot of developer love out there for Docker and it is continuing from last year.

Docker was the #1 most wanted platform and #2 most loved platform, according to the survey results published last week. We also ranked as the #3 most popular platform.

That’s no fluke. The results are based on nearly 65,000 people who code. And it’s the second year running we’ve acquitted ourselves so admirably in the annual survey. As we shared with you here last summer, developers ranked Docker as the #1 most wanted platform, #2 most loved platform and #3 most broadly used platform in the 2019 Stack Overflow Developer Survey. Those responses came from nearly 90,000 developers from around the world.

• This year, in the most wanted platform category, nearly 25 percent of developers expressed interest in developing with Docker, ahead of AWS (20.2 percent), Kubernetes (18.5 percent) and Linux (16.6 percent).

• In the most loved platform category, 73.6 percent of developers expressed interest in continuing to develop with Docker, trailing only first-placed Linux (76.9 percent), and leading Kubernetes (71.1 percent) and AWS (66. Continue reading
