Why Cannot I Create a Service Mesh for My Cluster?

Symptom

I cannot create a service mesh for my cluster.

Analysis

Currently, clusters earlier than v1.21 cannot be managed by service meshes.

Solution

1. Check the cluster version. Currently, only clusters v1.21 or later can be managed by service meshes.
2. Check your browser. Chrome is recommended. The button for service mesh creation may be unavailable when you are using other browsers, such as Firefox, due to adaptation problems.
