Can I add nodes that support Intel Software Guard Extensions (Intel SGX) to an existing cluster?
To add nodes that support Intel SGX to an existing cluster, the cluster must meet the following conditions:
- The Kubernetes version is 1.14.0 or later.
- The network plug-in is Flannel.
- The operating system is set to AliyunLinux 2.xxxx when you create the cluster. Do not select custom images when you add nodes to the cluster.
