Software Rollout at Scale: Using GitOps to Scale Kubernetes Rollouts

The reconciliation based paradigm of GitOps gives us a very convenient way of rolling out resources to a Kubernetes cluster, both applications and infrastructure. But how do we go from using GitOps to manage a single cluster to managing 10s, 100s or maybe even more clusters while still mitigating the risk if a rollout fails. This talk shows an opinionated way to manage rollouts at scale based on GitOps while still mitigating possible risk of failure. The talk is based on the experiences we gained scaling up at Netic.
