SKS Enhancements – Now Supporting Kubernetes 1.30 to 1.33 with Improved Security Defaults
We're excited to announce that Exoscale Scalable Kubernetes Service (SKS) now supports the following Kubernetes versions:
1.30.13
1.31.9
1.32.5
1.33.1
What's New
🔐 User Namespaces Enabled by Default in 1.33.1
Kubernetes 1.33.1 introduces user namespaces as a default feature in SKS. This critical security enhancement provides an extra isolation layer between containers and the host system, helping you run workloads more securely in multi-tenant and zero-trust environments.
User namespaces have been stable since Kubernetes 1.30.0, but with 1.33.1, we're enabling them out of the box.
Action required: To benefit from this security improvement, please upgrade your cluster nodes to version 1.33.1.

🛡️ AppArmor Enforcement Introduced
We've also introduced explicit AppArmor compatibility checks starting with this release.
While AppArmor has been usable in most past SKS versions, a recent regression highlighted the need for stricter validation. We now enforce prerequisites to ensure AppArmor is consistently available across all future Kubernetes versions on SKS.
