Your Guide to KubeCon + CloudNativeCon EU

Following on the heels of DockerCon SF, the team is packing their bags and heading to Barcelona for KubeCon + CloudNativeCon EU from May 20- 23. Docker employees, community members and Docker captains will be there speaking about and demonstrating Docker and Kubernetes.

Stop by Booth G14 to learn more about our Docker Kubernetes Services (DKS), which is part of the recently announced Docker Enterprise 3.0. Docker Enterprise 3.0 is the only container platform that provides a simple and integrated desktop-to-cloud experience for both Docker and Kubernetes.

Get Involved with Open Source

Get involved in and learn more about some of the projects Docker has been working on with the Kubernetes community:

  • containerd – the core container runtime that was recently graduated from the CNCF and is in use by millions of users
  • Notary/TUF –  a project designed to address the key security challenge for enterprises working with containers
  • Docker Compose on Kubernetes – a recently open-sourced project that enables users to take a Docker Compose file and translates it into Kubernetes resources.

Also, there is an opportunity to join Docker and Microsoft in contributing to the Cloud Native Application Bundle (CNAB) specification – an Continue reading

Microsoft issues fixes for non-supported versions of Windows Server

Microsoft took the rare step of issuing security fixes for both the server and desktop versions of Windows that are long out of support, so you know this is serious.The vulnerability (CVE-2019-0708) is in the Remote Desktop Services component built into all versions of Windows. RDP, formerly known as Terminal Services, itself is not vulnerable. CVE-2019-0708 is pre-authentication and requires no user interaction, meaning any future malware could self-propagate from one vulnerable machine to another.CVE-2019-0708 affects Windows XP, Windows 7, Windows Server 2003, Windows Server 2008 R2, and Windows Server 2008. It does not impact Microsoft’s newest operating systems; Windows 8 through 10 and Windows Server 2012 through 2019 are not affected.To read this article in full, please click here

HPE to buy Cray, offer HPC as a service

HPE has agreed to buy supercomputer-maker Cray for $1.3 billion, a deal that the companies say will bring their corporate customers high-performance computing as a service to help with analytics needed for artificial intelligence and machine learning, but also products supporting high-performance storage, compute and software.In addition to bringing HPC capabilities that can blend with and expand HPE’s current products, Cray brings with it customers in government and academia that might be interested in HPE’s existing portfolio as well.[ Now read: Who's developing quantum computers ] The companies say they expect to close the cash deal by the end of next April.To read this article in full, please click here

Another week, another devastating, industry-shaking, cybersecurity threat. This week’s is particularly haunting, though — the resurrected corpse of the Spectre and Meltdown vulnerabilities, aptly known as ZombieLoad. —Another week, another devastating, industry-shaking, cybersecurity threat. This week’s is particularly haunting, though — the resurrected corpse of the Spectre and Meltdown vulnerabilities, aptly known as ZombieLoad.

Today sees the publication of a range of closely related flaws named variously RIDL, Fallout, ZombieLoad, or Microarchitectural Data Sampling. The many names are a consequence of the several groups that discovered the different flaws. From the computer science department of Vrije Universiteit Amsterdam and Helmholtz Center for Information Security, we have “Rogue In-Flight Data Load.” —Peter Bright

Academic researchers today disclosed details of the newest class of speculative execution side-channel vulnerabilities in Intel processors that impacts all modern chips, including the chips used in Apple devices. —Swati Khandelwal

Researchers have discovered a severe vulnerability in Cisco products that could allow attackers to implant persistent backdoor on wide range devices used in enterprises and government networks, including routers, switches, and firewalls. —Mohit Kumar

Intel’s struggles to get its 10 nanometer processors out the door has forced the company to do some serious soul-searching. And while Continue reading

ngrok on Cumulus Linux

If you’ve landed on this page, you likely already have a good idea of what ngrok is and what it does. For those that don’t, the reader’s digest version is that it’s a simple way to securely tunnel to a device that sits behind a firewall/NAT device. It’s a slick implementation that is easy to install and allows a few different tunneling options. For the purpose of this blog, we’re using ssh and eliminating the need for port forwarding on the firewall.

Here are step-by-step instructions for turning up ngrok ssh services on Cumulus Linux. Note that these instructions work on the default VRF. You’ll need to take additional configuration steps to get this to work on Cumulus Linux with mgmt VRF enabled.

First, install the unzip package from the repo

Then wget the ngrok application, or optionally add the appropriate repo to your /etc/apt/sources.list and use apt to pull the package. You’ll obviously want to find the appropriate package for your switch (x86 or ARM).

If you don’t know the download link, navigate to https://dashboard.ngrok.com/get-started and copy the link address on the web link of the download section (right click the download link to snag the Continue reading

History of Networking: Pseudowires

Gone Fishin’

Well, not exactly Fishin', but I'll be on a month long vacation starting today. I won't be posting new content, so we'll all have a break. Disappointing, I know. Please use this time for quiet contemplation and other inappropriate activities.

 

If you really need a not so quick fix there's always the back catalog of Stuff the Internet Says. Odds are there's a lot you didn't read—yet.

You Don’t Want To Be A Rock Star

When I say “rock star”, you probably have all kinds of images that pop up in your head. Private planes, penthouse suites, grand stages, and wheelbarrows full of money are probably on that list somewhere. Maybe you’re a purist and you think of someone dedicated to the craft of entertaining the masses and trying to claw their way to fame one note at a time. But I’m also sure in both of those cases you also think about the negative aspects of being a rock star. Like ego. And lack of humility. I want to touch on some of that as it pertains to our jobs and our involvement in the community.

Great Like Elvis. Without The Tassels.

The rock star mentality at work is easy to come by. Perhaps you’re very good at what you do. You may even be the best at your company or even at the collection of companies that are your competitors. You’re the best senior architect there is. You know the products and the protocols and you can implement a complex project with your eyes closed. That’s how people start looking at you. Larger than life. The best. One of a kind.

And that Continue reading
