Where Does Istio Store Mesh Configs?
Where Istio keeps configs in cluster etcd on Linux servers. Full paths are listed below. More below.
Last updated
Istio is service mesh with cluster storage. Your gateways, policies, and telemetry live in etcd through the API server. Nodes run Envoy sidecars with local cache.
Same etcd plus operators means same mesh. Exact CRD versions shift with releases. Keep YAML exports beside snapshots. One missing revision restores routes without history. For moves, freeze changes first to avoid split config during copies. When in doubt, verify paths inside the app before trusting a remembered folder. Screenshots of settings help when support asks for reproduction steps later.
Where Istio Mesh stores this, by platform
/var/lib/istio (pilot cache, configs in etcd)
Mesh configs live in cluster etcd with revisions attached. Back up etcd plus operator files. Match releases before restore. Sidecars cache locally.
Frequently asked questions
How do I migrate Istio to a new cluster?
Back up etcd snapshots plus IstioOperator files with services steady, then install the same release on the new cluster before restore. Mesh configs follow etcd. Mixed releases can refuse old schemas, so match versions first.
Does Istio back up mesh configs?
Yes, in cluster etcd per namespace with revision history attached. Nodes hold a working copy plus proxy cache. Views rebuild after restore. Export YAMLs from namespaces for records, since node files alone are runtime state.
