OPC UA .NET Standard — Kubernetes Distributed Server Integration

OPCFoundation.NetStandard.Opc.Ua.Redundancy.Kubernetes adds opt-in Kubernetes integration to OPCFoundation.NetStandard.Opc.Ua.Redundancy.Server.

Overview

The package keeps Kubernetes concerns outside the base high-availability package. It provides Lease-backed leader election, peer discovery from EndpointSlices, an HTTP readiness/liveness bridge driven by OPC UA ServiceLevel, and a strongly-consistent multi-node Raft consensus wiring (UseKubernetesRaftConsensus, RaftCs over NanoMsg with an optional file WAL).

Getting started

services.AddOpcUa()
    .AddServer(...)
    .UseDistributedAddressSpace(options => options.UseLeaderElection = true)
    .UseKubernetesLeaderElection(options => options.LeaseName = "opcua-ha")
    .UseKubernetesPeerDiscovery(options => options.ServiceName = "opcua-ha-headless")
    .UseKubernetesReadiness(options => options.Port = 8080);

For strong consistency, wire a Raft cluster from the StatefulSet ordinals and compose it with UseRedundancyConsistency:

services.AddOpcUa()
    .AddServer(...)
    .UseKubernetesRaftConsensus(o =>
    {
        o.HeadlessServiceName = "opcua-ha-headless";
        o.ReplicaCount = 3;                      // static membership; odd for quorum
        o.StoragePath = "/var/lib/opcua/raft";   // PersistentVolume mount for the WAL
    })
    .UseRedundancyConsistency(RedundancyConsistencyMode.Strong);

Target frameworks

net8.0, net9.0, net10.0. .NET Framework and netstandard consumers use the base distributed package without Kubernetes integration.

See the Kubernetes high availability deployment guide for RBAC, Service, StatefulSet, readiness, and time-sync guidance.
