Request Forwarding
It specifies the service forwarding modes. Two service forwarding modes are available:
- iptables: traditional kube-proxy mode, which uses iptables rules to implement service load balancing. In this mode, too many iptables rules will be generated when many Services are deployed. Additionally, non-incremental updates will cause latency and obvious performance issues in the case of heavy service traffic.
- ipvs: optimized kube-proxy mode with higher throughput and faster speed. This mode supports incremental updates and maintains uninterrupted connections during Service updates. It is suitable for large-sized clusters.
Value Range
iptables or ipvs
Default Value
None
Modifiable
No. This parameter can only be configured during initialization.
Scope
CCE standard and CCE Turbo clusters
Suggestions
Select a forwarding mode based on the estimated number of Services used by clusters. If there are a great number of Services in use, set the parameter to ipvs.
