Azure Linux: A container host OS for Azure Kubernetes Service (AKS) Q&A
summary
Azure Linux is now GA on AKS as an RPM‑based container host built from source (CBL Mariner code on GitHub), deployed internally across ~300 services and used by ~100 enterprise preview customers; it supports ARM64 and x86_64, defaults to cgroup v1 with v2 available, keeps a small footprint (base VHD ≈350 MB, node image ≈30 GB), offers weekly image updates and a 72-hour CVE SLA for critical kernel fixes, and migrates simply by adding a node pool then cordon/drain old nodes.
