packages/system/cilium/charts/cilium/templates/hubble-relay/configmap.yaml (1)

19-19: LGTM! The addition of trailing dot follows DNS best practices.

The change makes the peer-service address a fully qualified domain name (FQDN) by adding a trailing dot, which prevents unintended DNS search domain appendix and ensures deterministic DNS resolution.

Let's verify this change aligns with Cilium's documentation:

packages/system/cilium/charts/cilium/files/cilium-envoy/configmap/bootstrap-config.json (2)

55-78: LGTM: Configuration structure is consistent

The internal_address_config is properly structured and consistently applied across all three listeners, following Envoy's configuration schema.

Also applies to: 146-169, 236-259

---

55-78: Security enhancement: Internal network access restrictions added

The addition of internal_address_config to all listeners enhances security by explicitly defining trusted internal networks. This change restricts access to metrics, admin, and health endpoints to only private networks and loopback addresses.

Please verify that these CIDR ranges cover all your internal networks:

• Private networks: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
• Loopback: 127.0.0.1/32, ::1/128

Also applies to: 146-169, 236-259

packages/system/cilium/charts/cilium/values.yaml (9)

156-156: Version update looks good.

The Cilium agent version update from v1.16.4 to v1.16.5 is a patch release, which should maintain backward compatibility.

---

159-159: Image digest update is consistent.

The new SHA256 digest ensures the integrity of the Cilium agent image v1.16.5.

---

1317-1317: Hubble relay version is in sync.

The Hubble relay version matches the Cilium agent version (v1.16.5), maintaining consistency across components.

---

1319-1319: Hubble relay digest is updated correctly.

The new SHA256 digest ensures the integrity of the Hubble relay image v1.16.5.

---

2168-2168: Envoy version update is aligned.

The Envoy proxy version has been updated to match the new Cilium release.

---

2170-2170: Envoy digest is updated correctly.

The new SHA256 digest ensures the integrity of the Envoy proxy image.

---

2483-2483: Operator version is in sync.

The Cilium operator version matches the agent version (v1.16.5), maintaining consistency across components.

---

2485-2491: Operator digests are updated for all providers.

The SHA256 digests for all Cilium operator variants (Generic, Azure, AWS, and AlibabaCloud) have been updated to match v1.16.5.

---

Line range hint 156-2491: Verify no remaining references to the old version.

Let's ensure there are no remaining references to v1.16.4 in the codebase.

✅ Verification successful

Version update to v1.16.5 is complete and consistent

All Cilium components have been properly updated to v1.16.5 with their corresponding image digests. No references to the previous version remain in the codebase.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for any remaining references to the old version
# This helps ensure the update was complete and consistent

echo "Checking for any remaining v1.16.4 references..."
rg -i "v1\.16\.4" || echo "No old version references found."

echo "Verifying all expected v1.16.5 references are present..."
rg -i "v1\.16\.5"
