Docker Online Meetup #41: Deep Dive into Docker 1.12 Networking

For this week’s Docker Online Meetup, Sr. Director, Networking at Docker, Madhu Venugopal, joined us to talk about Docker 1.12 Networking and answer questions.

Starting with Docker 1.12, Docker has added features to the core Docker Engine to make multi-host and multi-container orchestration simple to use and accessible to everyone. Docker 1.12 Networking plays a key role in enabling these orchestration features.

In this online meetup, we learned all the new and exciting networking features introduced in Docker 1.12:

• Swarm-mode networking
• Routing Mesh
• Ingress and Internal Load-Balancing
• Service Discovery
• Encrypted Network Control-Plane and Data-Plane
• Multi-host networking without external KV-Store
• MACVLAN Driver

The number of questions Madhu got at the end of the online meetup was amazing and because he did not have time to answer all of them, we’ve added the rest of the Q&A below:

Q: Will you address the DNS configuration in Docker? We have two apps created with docker compose and would like to enable communication and DNS resolution from containers in one of the apps to containers in the other app.

Check out the PTAL external network feature in docker compose in the Docker docs to get started. If that Continue reading

IDG Contributor Network: Shippable ships its newest thing: Industrial strength continuous deployment

Founded back in 2013, Shippable is one of the cool kids in the continuous deployment (CD) space. For those unaware, CD is a movement in which development teams deploy code frequently instead of in irregular and widely spaced occurrences. It is a movement popularized by organizations such as Facebook, Google and Twitter that deploy code many, many times a day.Shippable, therefore builds a platform to reduce friction and therefore allow software development teams to not only ship code fast, but far more frequently as well. DevOps, the movement that brought together the development and operations side of IT departments, aims to increase this velocity.To read this article in full or to leave a comment, please click here

Automation Gone Wild

My “this is why you need automation” blog post triggered numerous comments and tweets. I loved this one:

What if the mistake was embedded into the automation process/tool (designed by humans) in the first place? Now you have a video series titled "Automation Gone Wild".

I guess this tweet is a priceless answer to that question:

Facebook, Google, Twitter lax on terrorists’ misuse of their sites, say UK MPs

A panel of U.K. lawmakers has described as “alarming” that social networking companies like Facebook, Twitter and Google's YouTube have teams of only a few hundred employees to monitor billions of accounts for extremist content.“These companies are hiding behind their supranational legal status to pass the parcel of responsibility and refusing to act responsibly in case they damage their brands,” said a report released early Thursday in the U.K. by the Home Affairs Committee appointed by the House of Commons.To read this article in full or to leave a comment, please click here

This Android botnet relies on Twitter for its commands

Twitter users aren’t the only ones checking the microblogging service for important updates. Android malware is starting to do so, too.One maker of Android malware is using Twitter to communicate with infected smartphones, according to security firm ESET.The company discovered the feature in a malicious app called Android/Twitoor. It runs as a backdoor virus that can secretly install other malware on a phone.Typically, the makers of Android malware control their infected smartphones from servers. Commands sent from those servers can create a botnet of compromised phones and tell the malware on all the phones what to do.The makers of Android/Twitoor decided to use Twitter instead of servers to communicate with the infected phones.

Linux at 25: A retrospective

What a long, strange 25 years it’s beenImage by Reuters: USA Today Sports/Baz Ratner, WikimediaFrom its obscure origins to its present primacy, Linux is now old enough to rent a car without having to pay extra for insurance. It has also been described as the “the greatest shared technology asset in history,” and it’s the chassis upon which a sizeable proportion of all the software on the planet is built. Here’s a quick look back at Linux’s history.To read this article in full or to leave a comment, please click here

Why are SD-WANs taking off? Because they are secure, affordable and easy to use

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.Software-defined Wide Area Networking is red hot.  It is safe to assume that, going forward, every multi-location business will rely on SD-WAN for a cost-effective, high-quality, unified network solution.In fact, IDC recently released a report predicting SD-WAN revenue will reach $6 billion in 2020. Why?  Because SD-WANs are secure, affordable and easy-to-use. Those three magic words are enough to turn any CEO’s head, and the benefits go well beyond that.

When your government hacks you

There was a time when Cisco routers were unstoppable, and their deviations into proprietary protocols and constructions were accepted because Cisco could do no wrong. They were the smartest kids in networking protocols.But there is a crack in their armor, a glitch in the Teflon. Cisco may not be the only networking infrastructure vendor to now face an attack ostensibly from their own government, just the largest.Just as the U.S. government has taken Huwaei to task for an accusation of hidden code benefiting the Chinese government, other governments across the planet now know that their Cisco infrastructure can be cracked open—and no, it’s not easy, and requires an additional step of having hacked in from some place else.To read this article in full or to leave a comment, please click here

Worth Reading: One old guy’s advice

Having grown in my career since college, I have learned many lessons. I started out in computers back in 1986, at the precipice of the “Clone” era. I cut my teeth and my hands by installing chips on memory cards and motherboards, replacing 5.25” floppy discs, and dealing with the jumble of cables on Dual 5MB Winchester hard drives that cost and weighed an arm and a leg. —virtually tied to my desktop

Cisco vs. Arista: Shades of Gray

Yesterday was D-Day for Arista in their fight with Cisco over the SysDB patent. I’ve covered this a bit for Network Computing in the past, but I wanted to cover some new things here and put a bit more opinion into my thoughts.

Cisco Designates The Competition

As the great Stephen Foskett (@SFoskett) says, you always have to punch above your weight. When you are a large company, any attempt to pick on the “little guy” looks bad. When you’re at the top of the market it’s even tougher. If you attempt to fight back against anyone you’re going to legitimize them in the eye of everyone else wanting to take a shot at you.

Cisco has effectively designated Arista as their number one competitor by way of this lawsuit. Arista represents a larger threat that HPE, Brocade, or Juniper. Yes, I agree that it is easy to argue that the infringement constituted a material problem to their business. But at the same time, Cisco very publicly just said that Arista is causing a problem for Cisco. Enough of a problem that Cisco is going to take them to court. Not make Arista license the patent. That’s telling.
