Announcing Docker 17.06 Community Edition (CE)

Today we released Docker CE 17.06  with new features, improvements, and bug fixes. Docker CE 17.06 is the first Docker version built entirely on the Moby Project, which we announced in April at DockerCon. You can see the complete list of changes in the changelog, but let’s take a look at some of the new features.

We also created a video version of this post here:

Multi-stage builds

The biggest feature in 17.06 CE is that multi-stage builds, announced in April at DockerCon, have come to the stable release. Multi-stage builds allow you to build cleaner, smaller Docker images using a single Dockerfile.

Multi-stage builds work by building intermediate images that produce an output. That way you can compile code in an intermediate image and use only the output in the final image. So for instance, Java developers commonly use Apache Maven to compile their apps, but Maven isn’t required to run their app. Multi-stage builds can result in a substantial image size savings:

REPOSITORY          TAG                 IMAGE ID                CREATED              SIZE

Creating a wireless smart infrastructure: 4 expert recommendations

The mobile internet was a simpler infrastructure to design than the one that will be needed for the smart city, smart grid, smart health and smart transportation. Smartphones are homogeneous with relatively powerful processors and batteries driving transmission and reception. Designed to bring the internet to smartphones, 3G and 4G networks could be simpler. But IoT devices will span a range of heteroneous designs.The range of heterogeneity of the IoT is defined today by autonomous vehicles, which have thousands of sensors powered by high-capacity batteries that frequently communicate at high speed and low latency to simple sensors. Those sensors are powered by ambient power sources, sending a few infrequent bytes to communicate state (on/off, temperature, vibration amplitude and phase, etc.).To read this article in full or to leave a comment, please click here

Let’s Think Differently to Shape ‪Tomorrow

In 2015 the world made one of the biggest promises to itself in the form of 17 Global Goals set out by the United Nations. These goals – the Sustainable Development Goals (SDGs) – are aimed at achieving extraordinary things in the next 15 years. They are dedicated to fighting injustice and inequalities, ending climate change, beating discrimination, bringing in sustainable energy, and making sure no one goes hungry.

Docker at Nutanix .NEXT Conference – Visit us at Booth #S11

Today marks the start of Nutanix .NEXT Conference in Washington, D.C., the annual conference for Nutanix customers and partners. One of the major themes of the conference is hybrid cloud, and Docker will be there to demonstrate how Docker Enterprise Edition delivers application portability across different infrastructure platforms through a complete enterprise-ready Container as a Service (CaaS) solution for IT.

Docker and Nutanix will also be highlighting the Nutanix Docker Volume Plug-in (DVP), a Docker Certified Plugin available in the Docker Store. This plugin connects Docker containers to enterprise-grade persistent storage from Nutanix even as the container is powered on, powered off, or moved to a new host. As part of the certification process, Docker and Nutanix validate that the plugin is built with Docker recommended best practices and passes an additional suite of API compliance testing and vulnerability scanning. Docker EE customers also have access to support from both Docker and Nutanix.

 

Watch a Demo of Docker EE at Nutanix .NEXT

For those heading to Nutanix .NEXT, be sure to swing by booth #S11 to learn more about this plugin as well as other IT use cases for EE. Watch a demo and Continue reading

Stupidly Simple DDoS Protocol (SSDP) generates 100 Gbps DDoS

Last month we shared statistics on some popular reflection attacks. Back then the average SSDP attack size was ~12 Gbps and largest SSDP reflection we recorded was:

  • 30 Mpps (millions of packets per second)
  • 80 Gbps (billions of bits per second)
  • using 940k reflector IPs

This changed a couple of days ago when we noticed an unusually large SSDP amplification. It's worth deeper investigation since it crossed the symbolic threshold of 100 Gbps.

The packets per second chart during the attack looked like this:

The bandwidth usage:

This packet flood lasted 38 minutes. According to our sampled netflow data it utilized 930k reflector servers. We estimate that the during 38 minutes of the attack each reflector sent 112k packets to Cloudflare.

The reflector servers are across the globe, with a large presence in Argentina, Russia and China. Here are the unique IPs per country: 

$ cat ips-nf-ct.txt|uniq|cut -f 2|sort|uniq -c|sort -nr|head
 439126 CN
 135783 RU
  74825 AR
  51222 US
  41353 TW
  32850 CA
  19558 MY
  18962 CO
  14234 BR
  10824 KR
  10334 UA
   9103 IT
   ...

The reflector IP distribution across ASNs is typical. It pretty much follows the world’s largest residential ISPs:

$ cat ips-nf-asn.txt |uniq|cut -f 2|sort|uniq  Continue reading

Worth Reading: The blue disco ball

We deal with procurement departments every day. It’s a fact of modern day corporate life. But this week, I’ve had to respond to so many RFPs asking for “blue disco balls,” (my metaphoric name for a specific kind of middle management error that most vendors, suppliers and even solutions providers love most), I’m thinking about hanging one over my desk. What is a “blue disco ball?” Here’s a story I wrote last year about every senior executive’s worst nightmare and every vendor’s holiday bonus all rolled into a budget-busting good time. —Shelly Palmer

How do you troubleshoot UCaaS problems? Put a ThousandEyes on it

Cisco Live kicked off this week in Las Vegas. The annual event is where Cisco shows off its latest and greatest innovations, such as the intent-based networking system Cisco announced last week.However, it’s also a forum for many of Cisco’s technology partners to show off their wares in the World of Solutions Expo Hall. One of the more interesting vendors there was ThousandEyes, which demonstrated their network monitoring solution, as well as their new Unified Communications monitoring and management capabilities that provide visibility into the performance and connectivity across Unified Communications as a Service (UCaaS), on premises and hybrid VoIP deployments. To read this article in full or to leave a comment, please click here

Cisco upgrades one IoT platform and announces another

Following Cisco's launch last week of its Digital Network Architecture (DNA), which delivers intent-based networking solutions and services, this week’s Cisco Live event in Las Vegas was highly focused on networking. Only a few announcements were made, but the Internet of Things (IoT) made the cut.Cisco’s approach to IoT has been difficult to grasp because it crosses so many divisions. Its largest IoT unit, Cisco Jasper, is exclusively focused on cellular-connected devices.To read this article in full or to leave a comment, please click here

New Petyawrap Ransomware Attack Again Highlights Critical Need For Security Processes

Whenever there's a new attack on a global scale, the world trusts the Internet a little less. Today we are concerned with the many reports about this new ransomware attack called "Petyawrap", "Petrwrap" or an older name of "Petya."

The sad fact is: this new attack exploits the same vulnerabilities in Windows systems as last month's WannaCry attack. 

Fixes have been available for most Windows systems since March 2017!

The same tips Niel Harper provided last month to protect against ransomware also apply here.

Patching Not Enough to Stop Petya

Voluminous amounts of information have already been disseminated regarding the “Petya” (or is it “NotPetya”? [1]) ransomware that hit the Ukraine hard [2] along with organizations such as “the American pharmaceutical giant Merck, the Danish shipping company AP Moller-Maersk, the British advertising firm WPP, Saint-Gobain […]

What Cisco’s new programmable switches mean for you

To help ring in the 2017 New Year, CNN wanted to do a live shot from a Royal Caribbean cruise ship, but had an issue: “They were concerned about being out at sea, would they have the ability to live-stream?” says Royal Caribbean’s CIO Mike Giresi.The answer was yes, and the live-shot went off without a hitch, in part because the ship’s Cisco network gear was programmable to prioritize the video trafficAs an early implementer, Royal Caribbean has found benefits from regarding Cisco’s programmable infrastructure as a flexible asset that can be driven by software. “There are huge advantages to looking at the network as a software layer,” Giresi says. “It gives us the ability to create products, drive an experience and deliver services that are integrated with the infrastructure.”To read this article in full or to leave a comment, please click here

Giving Out Grades For Exascale Efforts

Just by being the chief architect of the IBM’s BlueGene massively parallel supercomputer, which was built as part of a protein folding simulation grand challenge effort undertaken by IBM in the late 1990s, Al Gara would be someone whom the HPC community would listen to whenever he spoke. But Gara is now an Intel Fellow and also chief exascale architect at Intel, which has emerged as the second dominant supplier of supercomputer architectures alongside Big Blue’s OpenPower partnership with founding members Nvidia, Mellanox Technologies, and Google.

It may seem ironic that Gara did not stay around IBM to help this …
