Adding an ECS to an ECS Group

Updated on 2022-09-23 GMT+08:00

Function

This API is used to add an ECS to an ECS group. The system automatically deploys the newly added ECS to a host that is different from the ones accommodating other ECSs in the ECS group.

Constraints

  • Only KVM ECSs can be added.
  • Only the anti-affinity policy is supported. ECSs in the same ECS group are deployed on different hosts, improving service reliability.
