Decoupling canary deployments from DBs with Argo Rollouts
Argo Rollouts offers well-known strategies for stateless applications, but what about deploying stateful applications that use databases? How can teams ensure safe, consistent, and reversible database updates when rolling out new application versions? This talk answers by showing how to decouple database migrations from application deployments through backward compatible schema changes to the database that allow both old and new application versions to operate simultaneously during the rollouts. We’ll also explore practical strategies for common database refactoring scenarios, including adding new columns, renaming columns and tables, and introducing new data types gracefully.
Don't Panic! A Beginner's Guide to K8s Debugging
It’s 9 AM on Monday morning, and you’re eager to dig into the new feature you’ve been designing over the past weeks. You write the code, deploy to testing, send your first request, and… it doesn’t work. Now what?
If you’re new to Kubernetes, this kind of thing can be a showstopper. Kubernetes is powerful and capable, but complex enough that knowing where to look when things go wrong can be a real challenge. This session, we’ll give you what you need for a fighting chance. We’ll look at how Services, Deployments, and Pods hang together; logging and events (and their strengths and weaknesses); basic observability using a service mesh; health checking; and some common gotchas along the way. We’ll use Linkerd for our examples, but everything we show is applicable to other technologies as well. Join us and walk away with tools you can use immediately to make life easier!
Autoscaling and Progressive Delivery - a match made in heaven
Argo Rollouts is a Kubernetes controller for Progressive Delivery deployments. In the most basic scenario, Argo Rollouts supports advanced Kubernetes deployments such as blue/green and canaries. While this is great, the main selling point of a Kubernetes cluster is the autoscaling facilities it offers. Can you use canary deployments while still taking advantage of Horizontal (and Vertical) autoscalers?
The answer is yes! In this talk, we will see how you can combine these two worlds - progressive delivery and autoscaling - and explain how to perform advanced deployments even in the presence of autoscalers.
Stop deploying blind! Using Observability and Argo Rollouts to Light the Way
Are you tired of looking at metrics and logs after each deployment? Do you learn about failed deployments from unhappy customers? Did you always want to deploy on Friday afternoon and go straight to the pub?
Many teams perform “blind” deployments without any real insight into what will be affected by the new application version. Consequently, they don’t have enough data to understand the blast radius of a release and whether to decide if it was successful or not.
Even companies that have several metrics in place, don’t always use them in an automated manner. Wouldn’t it be great if you could see user behavior with new features in real time and identify performance bottlenecks before a full release?
In this talk, we will focus on common scenarios regarding Argo Rollouts and observability metrics, we will explain:
- Minimum requirements in terms of tools and metrics/traces/logs
- Well-known observability use cases
- Common automation pitfalls
- RED/USE metrics tradeoffs
Why Allyship Matters and Your Role in Creating a More Diverse Cloud Native Community
Despite many DEI initiatives, diversity in open source is still lacking. That's not only bad for underrepresented groups, it's also bad for OSS (studies have shown time and again that diverse teams produce better outcomes). While there isn't much you can do about the industry's hiring practices, you can help make a difference!
As companies scale back on DEI efforts, community-driven change becomes essential—and that’s where allies come in. Minorities are, by definition, in the minority, and their advocacy alone has limits. Allies have the power to amplify underrepresented voices, raise awareness among peers, and advocate for change. When allies take a stand for inclusivity, accessibility, and ethical responsibility, they hold the power to influence the industry's values and priorities.
Join this panel with CNCF Deaf and Hard of Hearing WG members to learn how you can drive meaningful change and contribute to a more diverse, inclusive, and innovative open-source community.
