Stable 2.14.0 (#11282)
This release introduces direct pod-to-pod multicluster service mirroring. When clusters are deployed on a flat network, Linkerd can export multicluster services in a way where cross-cluster traffic does not need to go through the gateway. This enhances multicluster authentication and can reduce the need for provisioning public load balancers. In addition, this release adds support for the [Gateway API](https://gateway-api.sigs.k8s.io/) HTTPRoute resource (in the `gateway.networking.k8s.io` api group). This improves compatibility with other tools that use these resources such as [Flagger](https://flagger.app/) and [Argo Rollouts](https://argoproj.github.io/rollouts/). The release also includes a large number of features and improvements to HTTPRoute including the ability to set timeouts and the ability to define consumer-namespace HTTPRoutes. Finally, this release includes a number of bugfixes, performance improvements, and other smaller additions. **Upgrade notes**: Please see the [upgrade instructions](https://linkerd.io/2/tasks/upgrade/#upgrade-notice-stable-2140). * Multicluster * Remove namespace field from cluster scoped resources to fix pruning * Added -o json flag for the `linkerd multicluster gateways` command (thanks @hiteshwani29) * Introduced `logFormat` value to the multicluster `Link` Helm Chart (thanks @bunnybilou!) * Added leader-election capabilities to the service-mirror controller * Added high-availability (HA) mode for the multicluster service-mirror * Added a new `remoteDiscoverySelector` field to the multicluster `Link` CRD, which enables a service mirroring mode where the control plane performs discovery for the mirrored service from the remote cluster, rather than creating Endpoints for the mirrored service in the source cluster * HTTPRoute * Fixed `linkerd uninstall` issue for HTTPRoute * Added support for `gateway.networking.k8s.io` HTTPRoutes in the policy controller * Added support for RequestHeaderModifier and RequestRedirect HTTP filters in outbound policy; filters may be added at the route or backend level * Added support for the `ResponseHeaderModifier` HTTPRoute filter * Added support for HTTPRoutes defined in the consumer namespace * Added support for HTTPRoute `parent_refs` that do not specify a port * CRDs * Patched the MeshTLSAuthentication CRD to force providing at least one identity/identityRef * Control Plane * Send Opaque protocol hint for opaque ports in destination controller * Replaced deprecated `failure-domain.beta.kubernetes.io/zone` labels in Helm charts with `topology.kubernetes.io/zone` labels (thanks @piyushsingariya!) * Replaced `server_port_subscribers` Destination controller gauge metric with `server_port_subscribes` and `server_port_unsubscribes` counter metrics * Proxy * Handle Opaque protocol hints on endpoints * Added `outbound_http_balancer_endpoints` metric * Fixed missing route_ metrics for requests with ServiceProfiles * Fixed proxy startup failure when using the `config.linkerd.io/admin-port` annotation (thanks @jclegras!) * Added distinguishable version information to proxy logs and metrics * CLI * The `linkerd diagnostics policy` command now displays outbound policy when the target resource is a Service * A fix for HA validation checks when Linkerd is installed with Helm.

# Changes

|
||||
## stable-2.14.0
|
||||
|
||||
This release introduces direct pod-to-pod multicluster service mirroring. When
|
||||
clusters are deployed on a flat network, Linkerd can export multicluster
|
||||
services in a way where cross-cluster traffic does not need to go through the
|
||||
gateway. This enhances multicluster authentication and can reduce the need for
|
||||
provisioning public load balancers.
|
||||
|
||||
In addition, this release adds support for the
|
||||
[Gateway API](https://gateway-api.sigs.k8s.io/) HTTPRoute resource (in the
|
||||
`gateway.networking.k8s.io` api group). This improves compatibility with other
|
||||
tools that use these resources such as [Flagger](https://flagger.app/) and
|
||||
[Argo Rollouts](https://argoproj.github.io/rollouts/). The release also includes
|
||||
a large number of features and improvements to HTTPRoute including the ability
|
||||
to set timeouts and the ability to define consumer-namespace HTTPRoutes.
|
||||
|
||||
Finally, this release includes a number of bugfixes, performance improvements,
|
||||
and other smaller additions.
|
||||
|
||||
**Upgrade notes**: Please see the
|
||||
[upgrade instructions](https://linkerd.io/2/tasks/upgrade/#upgrade-notice-stable-2140).
|
||||
|
||||
* Multicluster
|
||||
* Remove namespace field from cluster scoped resources to fix pruning
|
||||
* Added -o json flag for the `linkerd multicluster gateways` command (thanks
|
||||
@hiteshwani29)
|
||||
* Introduced `logFormat` value to the multicluster `Link` Helm Chart (thanks
|
||||
@bunnybilou!)
|
||||
* Added leader-election capabilities to the service-mirror controller
|
||||
* Added high-availability (HA) mode for the multicluster service-mirror
|
||||
* Added a new `remoteDiscoverySelector` field to the multicluster `Link` CRD,
|
||||
which enables a service mirroring mode where the control plane
|
||||
performs discovery for the mirrored service from the remote cluster, rather
|
||||
than creating Endpoints for the mirrored service in the source cluster
|
||||
* HTTPRoute
|
||||
* Fixed `linkerd uninstall` issue for HTTPRoute
|
||||
* Added support for `gateway.networking.k8s.io` HTTPRoutes in the policy
|
||||
controller
|
||||
* Added support for RequestHeaderModifier and RequestRedirect HTTP filters in
|
||||
outbound policy; filters may be added at the route or backend level
|
||||
* Added support for the `ResponseHeaderModifier` HTTPRoute filter
|
||||
* Added support for HTTPRoutes defined in the consumer namespace
|
||||
* Added support for HTTPRoute `parent_refs` that do not specify a port
|
||||
* CRDs
|
||||
* Patched the MeshTLSAuthentication CRD to force providing at least one
|
||||
identity/identityRef
|
||||
* Control Plane
|
||||
* Send Opaque protocol hint for opaque ports in destination controller
|
||||
* Replaced deprecated `failure-domain.beta.kubernetes.io/zone` labels in Helm
|
||||
charts with `topology.kubernetes.io/zone` labels (thanks @piyushsingariya!)
|
||||
* Replaced `server_port_subscribers` Destination controller gauge metric with
|
||||
`server_port_subscribes` and `server_port_unsubscribes` counter metrics
|
||||
* Proxy
|
||||
* Handle Opaque protocol hints on endpoints
|
||||
* Added `outbound_http_balancer_endpoints` metric
|
||||
* Fixed missing route_ metrics for requests with ServiceProfiles
|
||||
* Fixed proxy startup failure when using the `config.linkerd.io/admin-port`
|
||||
annotation (thanks @jclegras!)
|
||||
* Added distinguishable version information to proxy logs and metrics
|
||||
* CLI
|
||||
* The `linkerd diagnostics policy` command now displays outbound policy when
|
||||
the target resource is a Service
|
||||
* A fix for HA validation checks when Linkerd is installed with Helm. Thanks
|
||||
@mikutas!!
|
||||
* Viz
|
||||
* Add the `kubelet` NetworkAuthentication back since it is used by the
|
||||
`linkerd viz allow-scrapes` subcommand.
|
||||
* Fixed the `linkerd viz check` command so that it will wait until the viz
|
||||
extension becomes ready
|
||||
* Fixed an issue where specifying a `remote_write` config would cause the
|
||||
Prometheus config to be invalid (thanks @hiteshwani29)
|
||||
* Improved validation of the `--to` and `--from` flags for the `linkerd viz stat`
|
||||
command (thanks @pranoyk)
|
||||
* Added `-o jsonpath` flag to `linkerd viz tap` to allow filtering output fields
|
||||
(thanks @hiteshwani29!)
|
||||
* Fixed a Grafana error caused by an incorrect datasource (thanks @albundy83!)
|
||||
* Fixed missing "Services" menu item in the Spanish localization for the
|
||||
`linkerd-viz` web dashboard (thanks @mclavel!)
|
||||
* Extensions
|
||||
* Added missing label `linkerd.io/extension` to certain resources to ensure they
|
||||
pruned when appropriate (thanks @ClementRepo)
|
||||
* Added tolerations and nodeSelector support in extensions `namespace-metadata`
|
||||
Jobs (thanks @pssalman!)
|
||||
* Init Containers
|
||||
* Added an option for disabling the network validator's security context for
|
||||
environments that provide their own
|
||||
* CNI
|
||||
* Added --set flag to install-cni plugin (thanks @amit-62!)
|
||||
* Fixed missing resource-cni labels on linkerd-cni, this blocked the
|
||||
linkerd-cni pods from coming up when the injector was broken (thanks
|
||||
@migueleliasweb!)
|
||||
* Build
|
||||
* Build improvements for multi-arch build artifacts. Thanks @MarkSRobinson!!

||||
