Redis Enterprise for Kubernetes 8.0.10-21 Released with ARM Support and OSS Cluster API
Redis released the 8.0.10-21 build of Redis Enterprise for Kubernetes in February 2026, adding ARM64 architecture support and OSS Cluster API compatibility for external clients.
Redis released version 8.0.10-21 of its Redis Enterprise Kubernetes operator in February 2026. The release is based on Redis Software 8.0.10-64 and introduces two significant additions for teams running Redis Enterprise on Kubernetes: native ARM64 architecture support and OSS Cluster API support for external clients.
ARM64 Architecture Support
The 8.0.10-21 release adds multi-architecture container images that transparently serve the correct image based on the node's architecture. When pulling images from Docker Hub or other registries, the registry automatically selects the AMD64 or ARM64 variant based on the host node. This enables Redis Enterprise to run on ARM-based Kubernetes nodes — including AWS Graviton instances, Azure Cobalt instances, and ARM-based on-premises servers — without changes to operator configuration or deployment manifests.
OSS Cluster API for External Clients
The release adds OSS Cluster API support for external clients, allowing Redis Cluster-aware client libraries to connect to Redis Enterprise databases from outside the Kubernetes cluster. Previously, clients connecting externally needed to route through a single endpoint, limiting the cluster topology visibility available to the client. With OSS Cluster API enabled, standard Redis Cluster clients receive accurate slot mapping and connect directly to the appropriate shard, eliminating the need for additional proxy configuration in cross-cluster topologies.
Bug Fixes and Known Limitations
The release resolves an issue with invalid containerStatuses indexing caused by incorrect ordering assumptions in the operator reconciliation loop. A separate fix removes unnecessary update calls from the services trigger to load balancers during normal cluster operation, reducing spurious API server load.
Several known limitations remain in this build, including issues with creating databases with duplicate names and warnings during operator bundle installation in certain environments. Organizations should review the full release notes in the Redis documentation before upgrading production clusters.
