help Oracle Container Engine for Kubernetes FAQ
Is Oracle Container Engine for Kubernetes a container runtime or a managed Kubernetes service?
Oracle's current product name is Oracle Kubernetes Engine, or OKE. It is a fully managed Oracle Cloud Infrastructure service for creating and operating Kubernetes clusters, while containerd and CRI-O are runtimes that run containers on worker nodes. [Oracle OKE documentation](https://docs.oracle.com/iaas/Content/ContEng/home.htm)
What runtime does OKE use on Oracle Linux worker nodes?
Oracle's documentation says Kubernetes 1.20 and later node pools using Oracle Linux 8 install and use CRI-O and crictl rather than Docker. The exact runtime depends on the selected node image and cluster setup. [Oracle worker-node image documentation](https://docs.oracle.com/en-us/iaas/Content/ContEng/Reference/contengimagesshapes.htm)
Can OKE use managed, virtual, or self-managed nodes?
Yes. Oracle documents virtual nodes, managed nodes, and self-managed nodes as worker-node choices, while Oracle manages the control plane for OKE clusters.
What does OKE manage for a production cluster?
OKE creates clusters and supports deployment, scaling, and management of containerized applications in Oracle Cloud Infrastructure. Its documentation also covers node pools, IAM access, add-ons, upgrades, secret encryption, and node lifecycle operations.
