Constraints on Clusters

Before creating a service mesh, ensure that you have an available cluster. Cluster versions and mesh versions must meet the adaptation rules listed in Table 1.

Table 1 Adaptation rules between ASM and cluster versions

v1.21, v1.23, v1.25, or v1.27

Containers on the node running Ubuntu 22.04 in a CCE Turbo cluster cannot be added to a service mesh earlier than v1.18.
