  • 1.28.0-gke.1
  • 1.27.0-gke.4
  • 1.26.0-gke.7

Starting from 1.28, clusters require outbound HTTPS connectivity to {GCP_LOCATION}-gkemulticloud.googleapis.com. Ensure your proxy server and/or firewall allows for this traffic.

1.28.0-gke.1

Removed the need to explicitly add Google IAM bindings for most features:

  • No longer need to add any bindings for gke-system/gke-telemetry-agent when creating a cluster.
  • No longer need to add any bindings for gmp-system/collector or gmp-system/rule-evaluator when enabling managed data collection for Google Managed Service for Prometheus.
  • No longer need to add any bindings for gke-system/binauthz-agent when enabling binary authorization.

1.28.0-gke.1, 1.27.0-gke.4 and 1.26.0-gke.7

Enhanced Cloud Logging's ingestion of logs from Anthos attached clusters:

  • Fixed an issue in timestamp parsing.
  • Assigned the correct severity level to the anthos-metadata-agent's error logs.

October 30, 2023

This release includes the following Anthos attached clusters platform versions:

  • 1.25.0-gke.8
  • 1.26.0-gke.6
  • 1.27.0-gke.3

1.25.0-gke.8, 1.26.0-gke.6, and 1.27.0-gke.3

Added support for attaching any CNCF-conformant Kubernetes cluster, in addition to EKS and AKS clusters. To attach a cluster, specify the distribution type as "generic".

1.27.0-gke.3

Removed deployment of Fluent Bit when logging is disabled.

October 02, 2023

This release includes the following Anthos attached clusters platform versions:

  • 1.25.0-gke.7

  • 1.27.0-gke.2

1.25.0-gke.7, 1.26.0-gke.5, and 1.27.0-gke.1

Resolved an issue affecting EKS environments in which Kubernetes resource metrics weren't successfully scraped from the kubelet when a node's name within the cluster didn't match that same node's hostname.

1.25.0-gke.7 and 1.26.0-gke.5

This release fixes the following vulnerabilities:

September 06, 2023

This release includes the following Anthos attached clusters platform versions:

  • 1.25.0-gke.6
  • 1.26.0-gke.4
  • 1.27.0-gke.1

1.27.0-gke.1

  • Added Binary Authorization support which is a deploy-time security control that ensures only trusted container images are deployed. With Binary Authorization, you can require images to be signed by trusted authorities during the development process and then enforce signature validation when deploying. By enforcing validation, you can gain tighter control over your container environment by ensuring only verified images are integrated into the build-and-release process. For details about how to enable Binary Authorization on your clusters, see How to enable Binary Authorization.

  • Added the authorization.admin_groups field. This allows users to specify Google groups as cluster-admins through the management plane.

  • Enabled gzip compression for fluent-bit's ingestion of logs into Cloud Logging. This improves the efficiency of log transfer for both the control plane and workloads.

  • Added proxy support for attaching AKS/EKS clusters. For details, see Connect to your EKS cluster and Connect to your AKS cluster.

This release fixes the following vulnerabilities:

August 03, 2023

This release includes the following Anthos attached clusters platform versions:

  • 1.24.14-gke.2700
  • 1.25.10-gke.1400
  • 1.26.5-gke.1400

July 12, 2023

Added support for managing Anthos attached clusters in the Google Cloud console. You can now use a user-friendly graphical interface to manage your Amazon Elastic Kubernetes Service (EKS) and Azure Kubernetes Service (AKS) clusters on the Anthos platform. Using the Google Cloud console, you can view cluster status, update attached cluster components, and detach clusters.
