Making Application Collaboration Easier with Docker Application Packages
In the first blog post about the experimental Docker Application Packages, Gareth showed how our new open-source docker-app can be used to augment Compose files by adding metadata and separate settings.
Now that you know how to create an Application Package, how do you share it? Using a Docker registry solution like Docker Hub or Docker Enterprise of course! Let’s look at an example that works with the latest release of docker-app. Here’s a simple single-file format Application Package with the filename hello.dockerapp:
# This section contains your application metadata. version: 0.1.0 name: hello description: "A simple HTTP echo server" maintainers: - name: Chris Crone email: [email protected] targets: swarm: true kubernetes: true --- # This section contains the Compose file that describes your application services. version: '3.6' services: hello: image: hashicorp/http-echo:${version} command: ["-text", "${text}"] ports: - ${port}:5678 --- # This section contains the default values for your application settings. port: 5678 text: hello development version: latest
We can save this Application Package as a Docker image using the save command:
$ docker-app save Saved application as image: hello.dockerapp:0. Continue reading
Encryption Is Critical for the Australian Economy
On 17 July 2018, the Internet Society and its locally based chapter, Internet Australia, joined 75 organizations in signing a letter urging Australia not to pursue legislation that could undermine the security of encrypted services and devices used by Australians.
As Internet Society CEO Kathy Brown wrote last year, “strong encryption is an essential piece to the future of the world’s economy … it allows us to do our banking, conduct local and global business, run our power grids, operate communications networks, and do almost everything else”.
Encryption should be the norm for all Internet traffic and stored data.
The Internet Society recognizes the concerns of law enforcement and remains firm in its conviction that encryption is an important technical solution that all Internet users should use to protect their communications and data. Legal or technical measures that weaken encryption or other digital security tools will place the well-being of law-abiding Australians, and the Internet at large, at risk.
We urge you to stand with us in support of encryption.

Smart Shopping Starts Today!
Let’s face it – things are different now than when we were kids.
I grew up with technology. My weekends consisted of frantically switching out floppy disks while on 13-inch-green-screen missions to destroy cubism-esque dragons, orcs and whatever else I could with my wizard powers. It taught me critical reasoning, innovative thinking, and gave me the courage to try new things.
Now that I’m a mom, I’m an advocate for my kids to use tech. But today’s tech is different. Now the Internet is everywhere and it’s a part of our everyday lives, in everyday things. Coffeemakers, toothbrushes, toasters, televisions and, yes – even teeth.
Did you ever think we’d have connected homes, let alone bras that might detect breast cancer?
These everyday things are known as the Internet of Things – IoT for short. It’s already everywhere.
Manufacturers are building connected things faster than most of us can keep up. While that means there’s lots of cool things hitting the shelves, many haven’t been built with our security or privacy in mind. That’s why we hear stories ranging from the somewhat humorous to the terrifying.
But we’re hungry for IoT devices – buying them as fast as manufacturers can Continue reading

Visualizing real-time network traffic flows at scale
Particles provide an intuitive representation of network packets transiting the network from source to destination. The animation slows time so that the particle takes 10 seconds (instead of milliseconds) to transit the network. Groups of particles traveling the same path represent flows of packets between the hosts. Particle size and frequency are used to indicate the intensity of the traffic flowing on a path.
Particles don't follow straight lines, instead following quadratic Bézier curves around the center of the screen. Warping particle paths toward the center of the screen ensures that all paths are of similar length and visible - even if the start and end points are on the same axis.
The example above is from a site with over 500 network switches carrying hundreds of Gigabits of traffic. Internet, Customer, Site and Datacenter hosts have been assigned to the North, East, South and West sides respectively.

On the ‘net: The Tradeoffs of Information Hiding
I recently joined Ethan Banks for a Packet Pushers episode around the trade offs of hiding information in the control plane. This was a terrific show; you can listen to it by clicking on the link below.
Today on the Priority Queue, we’re gonna hide some information. Oh, like route summarization? Sure, like route summarization. That’s an example of information hiding. But there’s much more to the story than that. Our guest is Russ White. Russ is a serial networking book author, network architect, RFC writer, patent holder, technical instructor, and much of the motive force behind the early iterations of the CCDE program.
