DevOps’ish 187

Normally, I don’t like to highlight military uses of Kubernetes (people have feelings about that; I do too, for that matter). But, this week, something rather significant happened out in Utah: U-2 Federal Lab achieves flight with Kubernetes. “The U-2 Federal Laboratory successfully leveraged Kubernetes during a local training sortie on a U-2 Dragon Lady assigned to the 9th Reconnaissance Wing at Beale Air Force Base, Sept. 22. This represents the first time Kubernetes has flown on an operational major weapon system in the Department of Defense.”

Yes, OpenShift and Kubernetes are in use in ground systems across the US Department of Defense. But, I’ve not heard of Kubernetes running on actual airframes until this week. The fact the team on the U-2 did this is quite stunning. Remember, U-2s were critical intelligence gathering sources on overflight missions during the Cuban Missile Crisis in 1962.

The U-2 program is a very old and sensitive program to the US government. As high and overarching as my clearances were, I never got close to the U-2 program (compartmentalization works). The U-2 is a critical C4ISR platform used in humanitarian and war fighting missions the globe over. The fact the U-2 program is leaning forward with containers and cloud native thinking makes me ask the same question I asked folks about DevOps and the US nuclear weapons program. “If they can do it, why can’t you?”

K8sContributors Twitter Account
Powered by Kubernetes SIG-Contributor-Experience; this is the Twitter account maintained by the Kubernetes Upstream Marketing Team (which you join by showing up to the meetings on Fridays). And yes, we’ve made the process to send a tweet conform to community governance (using GitHub approvals, etc.). It’s a great system that’s only going to get better with time thanks to the efforts of those on the Kubernetes Upstream Marketing Team. Follow K8sContributors and stay informed!

Microsoft is letting more employees work from home permanently
I’ve been working from home non-stop for two years and had several jobs that allowed for it prior to that. Your home office is something you have to invest in making a space you enjoy and appreciate. I need to do a lot of work and flip things on my desk at some point so I can get more natural lighting in my field of view. It’s just the next thing on the list. After that, there will be something small I can do to improve things. You don’t get a dope setup overnight unless you win the lottery.

Building Better Communication for Kubernetes Contributors with Marketing - Matthew Broberg, Red Hat, Kaslin Fields, Google & Rajula Vineet Reddy, CERN
The KubeCon + CloudNativeCon 2020 schedule has been posted. I would encourage everyone to attend this talk as everyone in the community will likely want to have something written about or given some more exposure at some point in their Kubernetes contributor journey.

Fixing our broken internet
“In unusually stark terms, Mozilla is trying to rally the troops to take back the internet from the forces of evil—or at least “misinformation, corruption and greed”—that have overtaken it. In a September 30 blog post, the organization behind the Firefox web browser warned that “the internet needs our love”. While there is lots to celebrate about the internet, it is increasingly under threat from various types of bad actors, so Mozilla is starting a campaign to try to push back against those threats.” Mozilla in trying to Unfck the internet.

One lone hero in production is not sustainable-not for you, not for high-functioning teams, and not for customers who depend on your service. Collaborate well by instrumenting observability from the very beginning, and enable more resilient teams to build more reliable systems sustainably.

IBM to spin off new company, will focus on $1 trillion cloud ‘opportunity’
”‘Now is the right time to create two market-leading companies focused on what they do best,’ said IBM Chief Executive Arvind Krishna in a statement. ‘IBM will focus on its open hybrid cloud platform and AI [artificial intelligence] capabilities. NewCo will have greater agility to design, run and modernize the infrastructure of the world’s most important organizations.‘” When I boss called me and asked if I’d heard the news that morning I said no. After he told me, I asked if there was an email announcement? He said, “Dude, it’s IBM. Check the internet.” To my credit, I was in the process of making coffee. But, that’s a very valid point. If Red Hat did this, no one would care. IBM does it and it’s a sea change.

Two wonderful comics from Julia Evans this week I’d like to highlight:

Download today: Kubernetes security ebook - tips, tricks, best practices
The rapid adoption of Kubernetes to manage containerized workloads is driving great efficiencies in application development, deployment, and scalability. However, when security becomes an afterthought, you risk diminishing the greatest gain of containerization - agility. Download this ebook to learn how to (1) build secure images and prevent untrusted/vulnerable code, (2) configure RBAC, network policies, and runtime privileges, (3) detect unauthorized runtime activity, and (4) secure your Kubernetes infrastructure components such as the API server.

Managing cgroups with systemd
“Find out how much easier cgroup management is with systemd in this four-part series finale covering cgroups and resource management.”

Measuring the Memory Overhead of a Postgres Connection
Everything comes at a cost.

Continuous Availability and Active-Active Bucket Replication
“One of the key requirements driving enterprises towards cloud-native object storage platforms is the ability to consume storage in a multi-data center setup. Multiple data centers provide resilient, highly available storage clusters, capable of withstanding the complete failure of one or more of those data centers. Multi-data center support brings private and hybrid cloud infrastructure closer to how the public cloud providers architect their services to achieve high levels of resilience.”

How Alibaba Cloud uses Cilium for High-Performance Cloud-Native Networking
Cilium is making a big push of late to highlight the platforms they support. I would expect to see them on openshift.tv at some point in the near future.

Memory Safe ‘curl’ for a More Secure Internet
“ISRG is funding Daniel to work on adding support for Hyper as an HTTP back-end for curl. Hyper is a fast and safe HTTP implementation written in Rust.”

Accurics Enables Self-healing Infrastructure with GitHub App
“It provides a library of more than 500 policies aligned with compliance standards such as the CIS benchmark. New commits and pull requests are automatically scanned for policy violations, and when security risks are found they are added to the PR and/or repo as issues. To help your team quickly eliminate them, you can even trigger new PRs with automatically-generated code to fix the issues.” Slick.

dheera/magicimport.py
“The idea of magicimport.py is to allow an arbitrary piece of Python code to fetch its own dependencies and versions at runtime and “just run”, no questions asked, without fuss. Behind the hood it uses virtualenv to create a virtual environment and install its dependencies there without messing with your system Python packages.”
