conduit v20.10.3 Release Notes

Release Date: 2020-10-15 // over 3 years ago

  • edge-20.10.3

    🚀 This edge release is a release candidate for stable-2.9.0. It overhauls the
    discovery and routing logic implemented by the proxy, simplifies the way that
    🔗 Linkerd stores configuration, and adds new Helm values to configure additional
    labels, annotations, and namespace selectors for webhooks.

    • ➕ Added podLabels and podAnnotations Helm values to allow adding additional
      labels or annotations to Linkerd control plane pods (thanks @tustvold!)
    • ➕ Added namespaceSelector Helm value for configuring the namespace selector
      👉 used by admission webhooks (thanks @tustvold!)
    • Expanded the 'linkerd edges' command to show TCP connections
    • Overhauled the discovery and routing logic implemented by the proxy:
      • The l5d-dst-override header is no longer honored
      • When the application attempts to connect to a pod IP, the proxy no
        longer load balances these requests among all pods in the service.
        The proxy will now honor session-stickiness as selected by an
        application-level load balancer
      • TrafficSplits are only applied when a client targets a service's IP
      • The proxy no longer performs DNS "canonicalization" to translate
        relative host header names to a fully-qualified form
    • 🔧 Simplified the way that Linkerd stores its configuration. Configuration is
      now stored as Helm values in the linkerd-config ConfigMap
    • 📇 Renamed the --addon-config flag to --config to clarify this flag can be used
      to set any Helm value
