Security Notices​

Palette Enterprise​

Features​

  • Palette now supports edit and delete operations on Cluster Profile Variables in non-Edge and connected Edge clusters. Additionally, you can now review and edit the values of Cluster Profile Variables when they are applied to existing clusters. This feature has now exited Tech Preview and is ready to use for production workloads. Check out the Cluster Profile Variables guide to learn more about this feature.

  • Self-hosted Palette installations now offer complete brand customization. System operators can apply custom logos and color schemes to the instances they manage by using the Customize interface tab in the Administration panel of the system console. Refer to the Customize Interface guide to learn more.

Improvements​

  • The rate limit for Palette API endpoints with a prefix of /v1/cloudconfigs has been increased to 50 requests per second per IP address, and the maximum burst has been increased to 250 requests per second per IP address.

  • The propagation of Azure cloud credentials has been improved to ensure that Palette automatically updates cluster secrets. This improvement ensures that clusters with expired credentials are updated immediately to prevent disruptions.

Edge​

Features​

  • Technical preview feature badgeTechnical preview feature badge Palette now supports a two-node architecture, which provides a High Availability (HA) mode. Users can enable this feature by toggling the high availability mode during cluster configuration. In HA mode, etcd is replaced with Postgres and Kine. Refer to the Two-Node Architecture page for further details.

VerteX​

Features​

  • Includes all Palette features, improvements, breaking changes, and deprecations in this release. Refer to the Palette section for more details.

  • Palette VerteX now offers complete brand customization. System operators can apply custom logos and color schemes to the instances they manage by using the Customize interface tab in the Administration panel in the system control. Refer to the Customize Interface guide to learn more.

Automation​

Features​

  • Terraform version 0.23.0 of the Spectro Cloud Terraform provider is available. For more details, refer to the Terraform provider release page.

  • All Terraform cluster resources now support Cluster Profile Variables management in non-Edge and connected Edge clusters. For more information, refer to the Spectro Cloud Terraform provider documentation.

  • A new Terraform resource, spectrocloud_resource_limit, is now available for managing Palette resource limits. By default, a resource limit is configured in Palette with default values. Users can now update the limits with Terraform. For more information, refer to the Spectro Cloud Terraform provider documentation.

Improvements​

  • Palette will now automatically use the most recent Pack version when no version is specified in Terraform resources. This improvement streamlines the user process of identifying and pulling the latest pack versions directly. Versions can still be defined explicitly. For more information, refer to the Spectro Cloud Terraform provider documentation.

  • The --validate flag of the Palette EC command now supports validation of airgapped environments. Previously, only environments that had internet access were supported. Refer to the Validate Environment section for further information.

  • The Terraform OCI registry resource, spectrocloud_registry_oci, now supports Zarf and Pack OCI Registry types. Previously, only Helm registries were supported. For more information, refer to the Spectro Cloud Terraform provider documentation.

Virtual Machine Orchestrator (VMO)​

Improvements​

  • The Virtual Machine Migration Assistant now allows TLS configuration for ingress resources, enhancing security through HTTPS access. This capability provides a unified and secure setup experience for users managing virtual machine migrations. Refer to the Create a VM Migration Assistant Profile guide to learn more.

  • The KubeVirt version in use is now v1.4.0. Other minor maintenance updates in support of Kubevirt 1.4.0 are also included.

Packs​

Pack Notes​

  • Palette's support for MicroK8s 1.29 and 1.30 has been enhanced to provide airgap support, as well as deployments on MAAS and AWS. Additionally, this update validates multi-node control planes.

  • Due to Google's decision to deprecate the gcr.io container registry, we have added a new image registry that Palette agents will use to pull images. The new registry is us-docker.pkg.dev. This was announced as part of the Palette 4.5.3 release. If you have network restrictions in place, ensure that the new registry is allowed. The migration of images to this new registry is now complete. Redirects from the old registry to the new registry are in place, so no user actions are required at this time. Refer to the Proxy Requirements for a complete list of domains that must be allowed.

  • The Palette eXtended Kubernetes (PXK) version 1.32.1 pack does not currently support AWS and GCP cluster deployments.
