Functions ¶
func GetLoggingOptions ¶
func PushCNIEvent ¶
func TestLoadArgs ¶
Validate k8sArgs struct works for unmarshalling kubelet args This is important for CNI plugin conformance
Types ¶
type CNIEventClient ¶
type CNIEventClient struct {
// contains filtered or unexported fields
}
An udsCore write entries to an UDS server with HTTP Post. Log messages will be encoded into a JSON array.
type Config ¶
type Config struct {
types.NetConf
// Add plugin-specific flags here
LogLevel string `json:"log_level"`
LogUDSAddress string `json:"log_uds_address"`
CNIEventAddress string `json:"cni_event_address"`
AmbientEnabled bool `json:"ambient_enabled"`
Kubernetes Kubernetes `json:"kubernetes"`
}
Config is whatever you expect your configuration json to be. This is whatever is passed in on stdin. Your plugin may wish to expose its functionality via runtime args, see CONVENTIONS.md in the CNI spec.
type InterceptRuleMgr ¶
InterceptRuleMgr configures networking tables (e.g. iptables or nftables) for redirecting traffic to an Istio proxy.
func IptablesInterceptRuleMgr ¶
func IptablesInterceptRuleMgr() InterceptRuleMgr
Constructor for iptables InterceptRuleMgr
type K8sArgs ¶
type K8sArgs struct {
types.CommonArgs
K8S_POD_NAME types.UnmarshallableString // nolint: revive, stylecheck
K8S_POD_NAMESPACE types.UnmarshallableString // nolint: revive, stylecheck
K8S_POD_INFRA_CONTAINER_ID types.UnmarshallableString // nolint: revive, stylecheck
}
K8sArgs is the valid CNI_ARGS used for Kubernetes The field names need to match exact keys in containerd args for unmarshalling https://github.com/containerd/containerd/blob/ced9b18c231a28990617bc0a4b8ce2e81ee2ffa1/pkg/cri/server/sandbox_run.go#L526-L532
type Kubernetes ¶
type Kubernetes struct {
Kubeconfig string `json:"kubeconfig"`
ExcludeNamespaces []string `json:"exclude_namespaces"`
}
Kubernetes a K8s specific struct to hold config
