(TODO: We need a derived version appropriate to send to cncf-maintainers list) # To CNFC Maintainers Sub: You're invited to the Kubernetes Contributor Celebration in one week! TL;DR we would love to have fellow cloud native contributors to join in the fun. Register now to be the first to join our Discord and we'll see you next week! https://forms.gle/51tqQgxuHxLaeU1P8 The Kubernetes community would normally celebrate this year by meeting in person, and that's not in the cards for us. So we decided to throw something fun online. With a change of venue, and with a lack of physical room limitations there’s no reason we can’t grow this to include all our friends and family! All we ask is that you register for logistical purposes. Here's the overview: - WHO: Everyone cloud native - WHAT: Games, competitions, and prizes! - WHEN: Friday, Dec 11th-Sunday Dec 13th* - WHERE: Discord (Register for an invitation) - WHY: Because it's nice to get to know each other out of code bases and Slack channels. \* We are opening up the Discord server Thursday night to get things started, so be sure to sign up before then. We have plenty of ad hoc space for all of you to group up and play games, or work, or do whatever you want. Friendly interproject rivalries are strongly encouraged. Hope to see you there.

"Doors open" Dec 10th (Thursday) for some early social fun, with events officially starting Dec 11th (Friday) and going into the weekend for the 12th and 13th! The plan is to hop onto Discord and have a good time filled with games, quiz shows, emojis, and prizes. **Only those who register will have access to the Discord Server** to avoid spam.

These are direct nominations from our SIG Chairs and Tech Leads, and from seeing the list of nominations this year we promise you won't want to miss the things out community has accomplished this year. # Everyone in Cloud Native is invited! We're scaling up! Due to our (over)commitment to automation and lack of physical room limitations there's no reason we can't grow this event! We're opening invites up to other cloud native projects as well and friends and family! From Helm maintainers to Prometheus contributors to Rust library authors in our space, please extend the invitation to them. All we ask is for you to send them to the registration form for logistical purposes. Bring a friend! We have plenty of ad hoc space for all of you to group up and play games, or work, or do whatever you want. Friendly interproject rivalries are strongly encouraged. # The Most Excellent Kubernetes Challenge and the Great Cloud Native Bake Off We have two(2!) sessions of the DevOpsParty game, one on Friday and one on Saturday, graciously hosted by Jeremy Meiss and Ian Coldwater. We will be giving away tons of prizes to the audience so you will for sure want to come. If you are an expert of the arcane parts of K8s and want to help us come up with blisteringly difficult questions, let Jeremy, Ian, or myself know directy or raise your hand in the #contributor-summit Slack channel. There will also be a 3 hour bakeoff on Saturday inspired by Great British Bakeoff! And Sarah Novotny confirmed she's baking! Join in for the baked goods, smack talk, and fun competition. Reach out to Paul Czarkowski to join in. Details here # Other Fun Things We have games like Among Us, Destiny, Fall Guys, and a variety of web games to choose from, along with sessions like Jonas Rosland's Video Game preservation talk. Lots of you have come to us with talk ideas but don't want to commit quite yet, this is fine! But please consider talking to us to put a fun session on the schedule if you're interested. https://k8s.dev/celebration On behald of Contributor Celebration Events team

Lessons Learned from 3 years of Kubernetes Office Hours

Date: 23 August 2020 Authors: Jorge Castro (VMware), Josh Berkus (Red Hat), Chris Carty (Google), Dan "POP" Papandrea (Sysdig), David McKay (Equinix Metal) Today we celebrate three years of the Kubernetes Office Hours. This is a monthly event where we take a panel of volunteers, stick them on a live stream, and then see how many questions we can field from the community. I started the show for one reason. I had recently started my Kubernetes journey and was learning all these new concepts while rewiring my traditional sysadmin brain to be more cloud native. So the idea was if I'm going to dig into this stuff and bother my new coworkers with silly questions, we might as well do it together and on the air to share our experiences and do it in a way that is fun and useful for others. Give away some tshirts, fame and fortune would surely follow. After 65 episodes we've decided to take a look at some of the more common problem areas that we've been tackling, and put together a quick summary for you on things where you might want to invest your attention. You will find many articles on "Top X things to know about Kubernetes". We've specifically avoided those and went back into our archives because what people think you need to know and what you actually need to know can be different.

EU Edition Panelists Person: Andrew Question: We're writing a controller with controller-runtime, and trying to use the Generation/ObservedGeneration pattern to avoid reconciling if there isn't any change (not using the predicate provided by controller-runtime for that purpose yet though). My question is how can that work with the possibility of a stale cache? When we write the ObservedGeneration to the Status of our CR, it triggers another reconcile immediately, but in some cases, the cache is stale and the CR it "Get"s still has the old Status, and therefore the old ObservedGeneration. What is the recommended strategy of dealing with this? Thanks! Person: Simone Baracchi Question: I'd like to configure my small cluster as "highly available" with no single master / single point of failure and make the best use of all the cluster resources. My current plan is to make 3 nodes run as masters and be able to schedule pods on the masters. From my research the issues in doing so are 1) security issues about sensitive data on master which could be read from malicious pods and 2) pods competing for resources (especially in case of a node failure). I'm not too concerned about security atm, and I can think of limiting the max number of pods / resources used. Is there any other red flag in doing so? Person: Jesper Berg Axelsen
