Is GitOps a Broken Experience - Where Is the Ops in GitOps ? - Rajalakshmi Kamath V, Walmart Global Tech

Wednesday December 11, 2024 2:55pm - 3:30pm IST

Room 5

Imagine the k8s resource model only had “spec” and not the “status”. How operationally challenging would it have been to infer this critical information from out of band approaches? While Gitops frameworks work very well to translate a pre-defined intended state, it fails to provide visibility into the actual state of the system. This entails a need to build tools to improve infrastructure observability. Gitops, also fails to address immediate operational control and recovery in the event of outages and offers a broken experience. Gitops has been the primary developer experience for Walmart running over 200k workloads and 10k deployments per day on 1000s of k8s clusters across public and private cloud. This talk highlights our learnings on building various ops tooling which provides deployment/running state of the workloads to complement our Gitops based deployment pipelines.

Modernizing Network Automation: Embracing Cloud-Native Excellence for Scalable Automation Platforms - Diana Appanna & Srivatsa Srinivasa, Nokia

Thursday December 12, 2024 11:30am - 12:05pm IST

Room 2

Traditionally, Network Management System (NMS) are very important and complex systems designed to help network operators from large service providers to small enterprises handling new service deployment, device lifecycle management, and fault management. However, their monolithic architecture combined all functions into one system, causing scalability issues and inefficiencies. The siloed design also impeded network management by isolating functions and restricting real-time monitoring. To address these constraints, we transitioned to a cloud-native architecture. We leveraged a comprehensive suite of open-source and CNCF technologies, including service mesh (Istio), container orchestration (Kubernetes), observability stack (Prometheus, Grafana, OpenSearch, Fluent Bit), and ingress gateway solutions (MetalLB, NGINX). This transformation resolved legacy issues while future-proofing our customers' networks, ensuring they stay agile, efficient, and prepared for future challenges.

A Debugging Journey from Coredns to Coreutils - Akhil Mohan & Humble Devassy Chirammal, VMware by Broadcom

Thursday December 12, 2024 11:30am - 12:05pm IST

Room 4

It all started when CoreDNS pods entered a crash loop backoff state soon after the cluster was deployed. The only change was an unprivileged execution desired in the latest coreDNS image. The issue occurred only in worker nodes, not in control plane nodes, and refreshing the image by deleting and pulling it again resolved the issue. It happened in one OS distribution flavor but not in another. We investigated Docker build, setcap, and libc, and found that the required capability was missing in nodes during the issue. The stack was complex, involving FIPS/CGO, build system, runtime configuration, and binary packaging in OVA. Debugging included CoreDNS binary, containerd, runc, SELinux, AppArmor, Photon OS, and the kernel... lots of learning which could be useful for many developers/admins or cluster operators to debug unprivileged pod execution. Finally, we discovered something interesting in the bootstrapping scripts. Let's debug.

Dynamic Management of X509 Certificates Using Kubernetes Certificate Operator - Abhidnya Joshi & Senthil Ponnuswamy, Dell Technologies

Thursday December 12, 2024 2:55pm - 3:30pm IST

Room 3

Security is non-negotiable area and Kubernetes based environments are no exception! Usage of x509 certificates is the key thing. Be it K8s deployments in private or public cloud, ensuring availability of "right" X509 certificate for a service is very important. If this service is getting connected from external (apps/clients which are outside of K8s cluster) clients, this is even more important! But what is really the "right" x509 certificate and how can we ensure that is always remains "right"? Can we make corrections dynamically? Can we also ensure easy propagation of certificates imported from outside the cluster? Propagation of Certificate revocation lists to ensure services can deny revoked certificates? This talk helps describe the strategy K8s based products can use to dynamically generate, make correction and propagation of X509 certificates within K8s cluster using K8s operator design pattern and makes use of well-known CNCF projects such as cert-manager and trust-manager.

Scaling Beyond Autoscaling: How We Grew Our Kubernetes Clusters - Bhavin Gandhi & Ruturaj Kadikar, InfraCloud Technologies

Thursday December 12, 2024 4:50pm - 5:25pm IST

Room 4

Picture this: Your startup just landed a big client, and as your business starts to grow, so does your Kubernetes cluster. The number of microservices and the traffic that they serve has started increasing. You configure auto-scaling of Nodes and Pods. Do you think that is enough, or do you need to look into other areas? What other components need scaling? What strategies should be devised? How do we verify whether there will not be any impact during scaling? In this session, we answer all these questions and come up with a blueprint for scaling a Kubernetes cluster from our experience with scaling our production cluster from merely 20-25 nodes to around 250 nodes with more than 5000 pods. We will touch base on the issues we faced and their resolution that will form a good prescription for those who want to scale their Kubernetes infrastructure.

Unleashing Observability: Enabling Distributed Tracing in gRPC with OpenTelemetry - Purnesh Dixit, Google

Thursday December 12, 2024 5:40pm - 6:15pm IST

Room 4

gRPC is often chosen for its high-performance communication, making it crucial to minimize latency. Distributed tracing helps identify and diagnose latency bottlenecks in gRPC calls, ensuring that the performance benefits of gRPC are fully realized. Setting up tracing from scratch for gRPC applications is complex and warrants significant maintenance overhead. Moreover, there is not much literature on how to do it properly, resulting in bespoke and suboptimal solutions. In this talk, Purnesh Dixit from the gRPC team will talk about the best practices for utilizing distributed tracing effectively in gRPC environments by configuring the new OpenTelemetry plug-in, created by the gRPC team in google.

Expedia Group's journey to implement GitOps with ArgoCD is a story of innovation, scalability, and overcoming challenges. Our GitOps journey involved migrating from KubeFed to ArgoCD, focusing on extensive scalability testing across hundreds of virtual clusters, set up using open source tool, vcluster. We proactively identified potential challenges and prepared comprehensive test cases tailored to different application flavors. We created three types of applications for testing, with sizes varying between 15-30 resources, including CRDs and jobs, small applications containing 15 resources and large applications containing 30 resources. We experimented with multiple test scenarios, using permutation and combination of applications tested on 300 vclusters, scaling approximately 1,000 applications to 30,000+ across these clusters. We concluded this initiative with determining optimal settings for various tunable parameters in the ArgoCD controllers.

Ensuring Reliability of Production Ready Kubernetes Operators Using Envtest - Aniruddha Basak, Syself GmbH & Richard Case, Stealth Startup

Thursday December 12, 2024 5:40pm - 6:15pm IST

Room 5

We need to keep in mind many principles & techniques while writing a Kubernetes operator and especially so when used in production. Projects like kubebuilder go a long way to help in building operators. However, talks focus on how to write operators. But in this talk, you will learn how testing can help you create Kubernetes operators that are reliable and resilient to failure and give you the confidence to deploy them to production clusters. Often writing unit tests is not enough for an operator that manages infrastructure. Introducing e2e tests will help, but writing and running e2e tests are time-consuming. This session will share how a user can use envtest to simulate an environment very similar to a real environment and run the tests on behalf of that. In addition, you’ll learn what to keep in mind while writing the tests, such as it doesn’t support garbage collection, and a user must be very careful while creating objects and deleting them after a test suite is done.
