Blocking (would cause production incidents):
- env var prefix: LUX_* → LUXD_* (27 vars). Viper reads only LUXD_*;
LUX_* silently ignored → node would start with default config on every env.
- admin API enabled + sybil disabled defaults: explicit LUXD_API_ADMIN_ENABLED=false
and LUXD_SYBIL_PROTECTION_ENABLED=true in base ConfigMap.
- bootstrap peer config absent in new overlays: added LUXD_BOOTSTRAP_IPS /
LUXD_BOOTSTRAP_IDS keys to base ConfigMap; overlays/operator populate per-env.
Defense-in-depth additions:
- ServiceAccount `luxd` with automountServiceAccountToken: false (no API access).
- PodDisruptionBudget maxUnavailable=1 (works at 5 → 100 validator scales).
- NetworkPolicy: ingress 9631/TCP from any (P2P), 9630/TCP cluster-only
(HTTP), 9090/TCP monitoring-namespace only (metrics).
- podAntiAffinity preferredDuringScheduling by hostname — spread across nodes.
- updateStrategy: OnDelete — operator drains one pod at a time.
- podManagementPolicy: Parallel — validators start in any order.
Swarm verdict was NO-GO until these fixes. Addresses red critical #1 (admin
API), #2 (sybil), high #4 (gateway bypass via direct LB), medium #7 (no
NetworkPolicy/RBAC), and scientist blockers on env prefix + bootstrap.
Single ghcr.io/luxfi/node image now includes luxd + EVM plugin +
all 11 chain VM plugins (aivm, bridgevm, dexvm, graphvm, identityvm,
keyvm, oraclevm, quantumvm, relayvm, thresholdvm, zkvm) built from
github.com/luxfi/chains.
Dockerfile: added plugin-builder stage that clones luxfi/chains and
builds each VM as a static binary placed at the CB58-encoded VM ID
path under /luxd/build/plugins/.
compose.yml: single-node local dev config (network-id=3, sybil off,
sample=1) replacing the stale docker/compose.yml.
k8s: replaced ad-hoc mainnet-only manifests with kustomize base +
4 overlays (localnet, devnet, testnet, mainnet). Each overlay patches
replicas, resources, storage class, network-id, and image tag.
Deleted: docker/Dockerfile, docker/compose.yml, docker/compose.genesis.yml,
k8s/luxd-statefulset.yaml, k8s/mainnet/ (entire directory).
