kubernetesUsing Rancher Fleet for GitOps‑driven Multi‑Cluster Deployments
Learn how Rancher Fleet uses GitOps to keep multiple Kubernetes clusters in sync, with a step‑by‑step NGINX Ingress example, trade‑offs, and verification steps.
Protecting Rancher Itself: Encrypted rancher-backup Schedules to S3 and Restore Rehearsals
Rancher is the front door to your clusters. Learn how to schedule encrypted rancher-backup backups to S3-compatible storage, verify the result, and rehearse a restore while keeping downstream etcd and app backups separate.
Choosing Between Rancher Built‑In Monitoring and a Self‑Managed Stack
Decide whether to use Rancher’s built‑in monitoring or a self‑managed stack, compare resource overhead and flexibility, then follow a step‑by‑step enable‑and‑verify procedure.

Learn how to use the Rancher agent to import existing Kubernetes clusters into a centralized management plane, reducing configuration drift and simplifying multi-cluster RBAC.
Choosing Between RKE2 and K3s for Rancher-Managed Production Clusters
A decision guide for choosing between RKE2 and K3s for Rancher-managed clusters, with a comparison table, trade-off analysis, and a concrete validation workflow.
Safely Upgrading Kubernetes Clusters at Scale with Rancher’s Built‑in Upgrade Workflow
Learn how Rancher’s built‑in upgrade workflow turns risky, manual Kubernetes version bumps into a controlled, auditable operation—complete with a step‑by‑step example, limitations, and verification steps.
Rancher External Identity Providers: A Minimal SAML/OIDC Architecture for Multi-Cluster SSO
An architecture note on wiring Rancher 2.x to a SAML or OIDC identity provider: the minimal design, trust boundaries around etcd, verification steps, and the failure modes that actually bite.
Rancher Multi-Cluster Management: What Centralizing Your Clusters Actually Buys You
Rancher's multi-cluster management centralizes auth, RBAC, and GitOps delivery across imported and provisioned clusters — but the management plane itself becomes a dependency you must design for.
