**Erik St. Martin:** And this is monthly? |
**Carlisia Thompson:** Yes. |
**Erik St. Martin:** Awesome. So before we move on, where should people go to sign up for that if they are not already signed up? |
**Carlisia Thompson:** It's basically the GoBridge blog, and I want to correct myself - her name is Amy Chan. We need to remember to say people's last name. So Amy Chan, thank you, you did an amazing job. People can sign up at the GoBridge Blog. |
**Erik St. Martin:** Awesome. So \#FreeSoftwareFriday. Today is Thursday, but we do it for Friday. We like to give shout outs to people or projects that are making our lives easier. Carlisia, do you wanna kick it off? |
**Carlisia Thompson:** Yes. |
**Erik St. Martin:** What do you have this week? |
**Carlisia Thompson:** I'm gonna mention a project that I actually solicited on the GoTime channel, because I didn't have one, but I definitely wanted to give a shout out to somebody. And now I didn't write his name here, I forgot, the person who mentioned it. The package is called Kinetic, and it's an easier way to ac... |
**Erik St. Martin:** Oh, interesting. |
**Carlisia Thompson:** Yeah. The official description says "high-performance AWS Kinesis Client for Go." |
**Nate Finch:** Nice. So my shout out is to Hugo, which was originally written by Steve Francia. It is the static website generator that I think most people know about, but that's what I use to pick my blog. Lots of people do, and there's been a ton of work on it. |
\[55:59\] Lately a lot of it is being done by Bjorn-somebody (Bjørn Erik Pedersen) Sorry, I don't have his name in front of me. It's gotten even faster, and it's really a great way to build a website. It looks nice and it's easy to update, and very usable. |
**Erik St. Martin:** Yeah, Hugo is really awesome. It's actually what the GopherCon and Gopher Academy sites are all running. And even if you're not familiar with Hugo itself, you're probably familiar with some other projects that came out of it. Cobra and Viper were both by spf13, which is Steve Francia. They are both... |
Mine today is actually called CNI, the Container Networking Interface. I wanna give a shout out to everybody who is involved in that project, because it's really cool for Kubernetes for networking logic; it allows you to inject your own executable into the flow to allocate an IP address or set up routes when containers... |
With that, we are out of time unfortunately. |
**Carlisia Thompson:** Can I make two quick thanks? |
**Erik St. Martin:** You certainly can! |
**Carlisia Thompson:** So many thanks... Huge shout out to everybody in Brazil who are there for GopherCon Brazil. |
**Erik St. Martin:** Yes... |
**Carlisia Thompson:** I already see people having a great time. The conference starts tomorrow, so it's tomorrow and Saturday. And Erik is giving a great talk about Kubernetes; Erik, you didn't mention that, so I have to. The talk is entitled -- I'm trying to find the name of the talk here... |
**Erik St. Martin:** It's called Kubernetes As Seen On TV. |
**Carlisia Thompson:** Yes! So check it out, it's gonna be at KubeCon November 8-9, but Erik's talk is on 9th November. |
**Erik St. Martin:** Speaking of which, because of that we won't have a show next week. I'm traveling for that, Brian is traveling - I think he's in Amsterdam next week... I think everybody's traveling, so we will be skipping next week's show unless we can find time to squeeze one in not live in off time, but let's ass... |
With that, I wanna thank everybody for being on the show today. Huge shout out to our sponsors, both to Stackimpact and Code School, thank you to all of our live listeners and future listeners. Definitely forward this to your friends. |
We are @GoTimeFM on Twitter, we have a GoTimeFM channel on the Gophers Slack. If you are not subscribed already, go to GoTime.fm, our website for email. If you wanna be on the show or you have ideas for guests or topics for this show, hit us up on github.com/gotimefm/ping. With that, everybody goodbye. |
**Carlisia Thompson:** Thank you, Nathan. Goodbye! |
**Nate Finch:** Thank you! |

• The intersection of sysadmin skills and coding, and how Kelsey brings his operational expertise to development roles |
• Kubernetes as a system that codifies ops people's expertise, requiring operational knowledge to deploy and maintain |
• Abstraction in Kubernetes: abstracting users from cluster operation concerns, but still requiring focus on retry logic, logging, etc. |
• Kelsey's analogy of Kubernetes as the runtime for infrastructure, much like Go's runtime for applications |
• The comparison of Kubernetes to a kernel or operating system, with potential implications for self-deploying applications and system call interfaces |
• The relationship between Golang and Kubernetes: how Go's strengths (cross-platform executables, concurrency) make Kubernetes special |
• Discussing the prevalence of Go-written tools in the Kubernetes ecosystem |
• Explaining Kubernetes' plugin architecture and how it allows for custom extensions without recompiling the system |
• Describing the concepts of desired state, reconciliation, and controllers/schedulers in Kubernetes |
• Comparing Kubernetes to other systems like Puppet, CFEngine, Chef, and Ansible in terms of declarative vs. imperative programming models |
• Discussing the use of labels and soft/hard requirements for scheduling in Kubernetes 1.4 |
• Kubernetes as a framework for building distributed systems |
• Kubernetes is not just about deploying containers, but can be used to build new systems and workflows |
• Core object types in Kubernetes (node, pod, controller, service) and how they enable extensions such as deployments and replica sets |
• Extending the system with user-defined types at runtime using third-party resources |
• Importance of abstraction layers on top of core objects to facilitate tasks and interactions with the cluster |
• Exploring and integrating Kubernetes into existing applications and workflows for developers who may not be familiar with DevOps tools |
• Docker vs Kubernetes: Developers may be less interested in cluster management and deployment, focusing on app development |
• Kubernetes concepts: Automated scheduling, resource allocation, scaling, and load balancing |
• Twelve-Factor App principles: Importance of decoupling from machine dependencies, using environment variables, logs to STDOUT |
• Integrating Twelve-Factor with Kubernetes: Using config maps and secrets for configuration injection |
• Containerization vs cluster management: Understanding the differences between Docker, Kubernetes, and DevOps practices |
• Kubernetes can be overkill for simple applications and comes with its own set of management tasks |
• Kelsey Hightower notes that even if a well-designed application doesn't need Kubernetes initially, it's becoming an expected feature as customers demand high uptime and availability |
• Google Cloud's GKE (Google Kubernetes Engine) is mentioned as a commercial offering of Kubernetes and provides deep integrations with the Google Cloud platform |
• The Pokémon GO example is cited as a real-world success story for Kubernetes in handling high traffic and revenue-generating workloads |
• Kelsey Hightower discusses his idea of self-deploying Go applications, where an app can automatically deploy itself on Kubernetes without manual YAML files or complex configuration |
• He showcases his prototype "Hello, Universe" which demonstrates this concept by allowing users to scale and manage their application across multiple clusters with ease. |
• Kubernetes allows users to submit a configuration for a channel lineup or cable television and have the system manage it without worrying about hardware or software details |
• The system provides concurrency capabilities "for free" in terms of not requiring additional setup or infrastructure |
• Cluster Federation is a new feature that enables managing multiple clusters as a single cluster, making it easier to handle large, complex deployments |
• Live demos can be an effective way for presenters to demonstrate concepts and inspire others to try them themselves |
• Kelsey's ability to explain complex topics in an engaging way |
• Support and development of the Go language for projects like Kubernetes |
• Native vendoring directory and third-party dependency management |
