type LocalMode ¶ added in v1.18.0
type LocalMode string

type ProxyMode ¶
type ProxyMode string
ProxyMode represents modes used by the Kubernetes proxy server.
Currently, two modes of proxy are available on Linux platforms: 'iptables' and 'ipvs'. One mode of proxy is available on Windows platforms: 'kernelspace'.
If the proxy mode is unspecified, the best-available proxy mode will be used (currently this is `iptables` on Linux and `kernelspace` on Windows). If the selected proxy mode cannot be used (due to lack of kernel support, missing userspace components, etc) then kube-proxy will exit with an error.
