Infra side of ADR-0014: an mTLS gRPC consumer of Calico Goldmane's Flows API
that records the namespace-pair edge-set in CNPG and posts a daily new-edge
digest to #security. Adds the goldmane-edge-aggregator stack, the
pg-goldmane-edges Vault rotation role (Tier-0 vault state updated here), and the
namespace in the ghcr-credentials allowlist.
Cert: REUSES the operator-minted, Tigera-CA-signed whisker-backend client cert
(Goldmane verifies only the CA chain, not identity) instead of minting from the
Tigera CA private key. This avoids putting the CA key in TF state AND the
hashicorp/tls provider, which is incompatible with this repo's global
generate-providers/lockfile pattern (it broke every stack's lockfile).
Verified live: aggregator streaming flows, 174 edges in Postgres across 50x54
namespaces, db+slack ExternalSecrets synced, digest dry-run formats correctly,
private image pulls via the Kyverno-synced ghcr-credentials.
