Kubernetes Quick Wins and Migration Best Practices: RingCentral Example
summary
RingCentral describes a multi-year Kubernetes migration that yields concrete practices: greenfield analytics launched in four months, five‑nines production SLA maintained, and daily deploys enabled by Flux + GitOps. Toolchain details include Flagger canaries, testkube for in-cluster tests, Kyverno policy enforcement, NixOS + Bazel for hermetic builds, and GitLab for orchestration. They package manifests as OCI images, apply OCI image signing with multiple signatures to gate promotions, and report the workflow reduces human error and supports asynchronous safe rollouts.
