Tanzu Service Mesh 5.0.7
Released July 5, 2022
Release 5.0.7 includes support for external services as well as wildcards; external services (for example, third-party database services) located outside the VMware Tanzu Service Mesh are made accessible by services inside the Mesh's global namespace. External services can run on virtual machines, external Kubernetes clusters, Tanzu Application Service (TAS) environments, lambda functions or even on bare metal, and can be accessed over TCP, TLS, HTTP, or HTTPS. When connecting to the external service using an HTTPS or TLS protocol, a TLS certificate can be added if desired. Users can define multiple external endpoints for a single external service, and they can load balance them (round-robin scheme by default); they can also edit existing external services to add additional endpoints.
Each external server has a subdomain through which we can access the external service. Tanzu Service Mesh offers the ability to match subdomains of external service hostnames using wildcards; it is possible for services inside Tanzu Service Mesh global namespace to connect to external servers whose hostnames are in wildcard format (for example, *.google.com, *.wikipedia.com). With wildcard capabilities, you can select exactly which servers to connect to from a list of wildcard servers.
Users can view details about external services, including their configuration and performance metrics, which are useful for monitoring their performance. External service configuration can also be edited. Future releases will include support for traffic management and access control policies for external services.
Release 5.0.7 retains Istio 1.12.2. Istio 1.12.2 contains security updates and Telemetry customization. For the details contained in Istio 1.12.2, see the Istio 1.12 release notes and Istio 1.12.2 release notes.
Tanzu Service Mesh 5.0.7 components are outlined in the Data Plane Components table. This release retains the metrics proxy version 3.2.0 and Telegraf version 1.18.3.
Known issues include wildcards with external services that require a live www server in the list of external servers, and the service port and gateway port should not be the same for multiple endpoint configurations.

Tanzu Service Mesh 5.0.4 (Upgraded to 5.0.6)
Released March 29, 2022
Release 5.0.6 includes use of the public ECR registry as well as support for custom registries; custom registries are any registry under the user's control, such as private or local enterprise registries. In the event the custom registry requires authentication, users are required to create a secret in all namespaces requiring authentication to the custom registry in order to pull images; this includes vmware-tsm-system, istio-system, kube-system, and any new namespaces that will require pulling sidecar images. If credentials are required for a custom docker registry, the SECRET authentication type must be used.
When onboarding a new cluster with a custom registry definition, the Tanzu Service Mesh images (Istio and TSM agents) will be downloaded from that registry. At the current time, changes to the registry definition on already onboarded clusters aren't supported. Deleting a registry definition that has been used for onboarding clusters will result in a failed restart for certain pods; this is because the registry definition is no longer valid, and Tanzu Service Mesh does not support updating that definition at the moment. In case of deleting the registry definition, the affected clusters that were onboarded with it must be re-onboarded. A warning about this implication will show up when one tries to delete the definition. Future releases will include support for updating a registry definition.
Release 5.0.6 brings in Istio 1.12.2. Istio 1.12.2 contains security updates and Telemetry customization. Istio Telemetry is retained, but will be deprecated in future releases. For the details contained in Istio 1.12.2, see the Istio 1.12 release notes and Istio 1.12.2 release notes.
Tanzu Service Mesh 5.0.6 components are outlined in the Data Plane Components table. Metrics proxy has been updated to 3.2.0, and Istio has been updated to 1.12.2 with this release. The version has been patched with fixes for the Envoy OAuth filter.
A known issue is that Kubernetes CoreDNS ConfigMap customization would be lost after the upgrade of the TSM data plane. Read this article to find out more.
Kindly upgrade Tanzu Service Mesh data plane version 5.0.4 to 5.0.6. The upgraded version (5.0.6) contains fixes for Envoy OAuth vulnerability which became public on June 9, 2022. For more information, see CVE-2022-29226 Detail.
