Changes

This release removes the initial delay for the policy controller, allowing for faster control-plane startups, quietens the policy controller's reconciliation logs, and adds logging to make it clear which policy-controller pod is responsible for updating statuses.

What's Changed

  • build(deps) update go linkerd2-proxy-api to v0.15.0 by @olix0r in #13396

Changes

In this release, the proxy emits new request_frame_size and response_frame_size metrics with information about TCP frame distributions, correctly accounts for closed connections in route metrics, and fixes a (rare) panic for resources in which managedFields has no timestamp. Additionally, linkerd check checks to be sure that your Link resources match your CLI version, keywords in docker build now use correct cases (thanks, Derek Brown!), and we now test Linkerd on Kubernetes 1.31.

N/A

Changes

This release fixes a bug (issue 13327) where Linkerd could constantly re-update the status clause of HTTPRoute if another Gateway API controller was present in the system (thanks Derek Brown!), ensures that all of the proxy-injector's logs are valid JSON when JSON logging is enabled (thanks, Micah See!), and cleans up HTTPRoute validation to make sure that if a backendRef is a Service, it must have a valid port.

N/A

Changes

edge-24.11.3 brings local rate limiting to Linkerd! Using the new HTTPLocalRateLimitPolicy resource, you can attach rate limits to Servers to protect workloads from being overwhelmed by excessive traffic. Additionally, it improves metrics for TCPRoute and TLSRoute egress control, correctly handles the case where a Route type changes parents (fixing [issue #13280]), allows linkerd diagnostics endpoints to correctly handle workloads with multiple endpoints, and removes unneeded references to linkerd-base from the linkerd-control-plane chart README (thanks, Brandon Ros!).

NOT RECOMMENDED

Overall status: NOT RECOMMENDED, use edge-24.11.3 instead

Cautions

linkerd diagnostics endpoints may not correctly show all endpoints for federated Services. We recommend using edge-24.11.3 instead, which fixes this issue.

Changes

edge-24.11.2 brings federated Services to Linkerd multicluster setups! Every federated Service appears exactly the same from every cluster (rather than having names like svc-cluster) and Linkerd seamlessly handles everything to gather the relevant endpoints from all clusters, without requiring application changes or HTTPRoute configuration.

Changes

edge-24.11.1 brings egress monitoring and control to Linkerd! Using the new EgressNetwork CRD as a parentRef for an HTTPRoute, GRPCRoute, TCPRoute, or TLSRoute, you can see which workloads are making egress calls and set policy on what's allowed and what isn't.

RECOMMENDED

Overall status: RECOMMENDED

Cautions

As of edge-24.10.5, if you configure a timeout on a GRPCRoute, a request that hits the timeout will correctly return a DEADLINE-EXCEEDED gRPC status rather than an UNAVAILABLE gRPC status.

Changes

edge-24.10.5 fixes a bug where requests that hit GRPCRoute timeouts would return gRPC status UNAVAILABLE instead of DEADLINE-EXCEEDED.

edge-24.10.4 disables automountServiceAccountToken in favor of explicitly-configured projected volumes for the ServiceAccountTokens we need (thanks, Aran Shavit!) and updates the deprecation text for Server v1beta1 (thanks, @patest-dev!).
