Types

type AgentDeployConfig

type AgentDeployConfig struct {

	Image string
	// DefaultPeriod is the default period for jobs.
	DefaultPeriod time.Duration
	// DefaultSeccompProfileEnabled if seccomp profile should be defaulted to RuntimeDefault for the daemonsets.
	DefaultSeccompProfileEnabled bool
	// PingEnabled if ping checks are enabled (needs NET_ADMIN capabilities).
	PingEnabled bool
	// IgnoreAPIServerEndpoint if the check of the API server endpoint should be ignored.
	IgnoreAPIServerEndpoint bool

	PriorityClassName string
	// K8sExporterEnabled if node conditions and events should be updated/created.
	K8sExporterEnabled bool
	// K8sExporterHeartbeat if K8sExporterEnabled sets the period of updating the node condition `ClusterNetworkProblems` or `HostNetworkProblems`.
	K8sExporterHeartbeat time.Duration
	// K8sExporterMinFailingPeerNodeShare if > 0, reports node conditions `ClusterNetworkProblems` or `HostNetworkProblems` for node checks only if minimum share of destination peer nodes are failing. Valid range: [0.0,1.0].
	K8sExporterMinFailingPeerNodeShare float64
	// AdditionalAnnotations adds annotations to the daemonset spec template.
	AdditionalAnnotations map[string]string
	// AdditionalLabels adds labels to the daemonset spec template.
	AdditionalLabels map[string]string

	DisableAutomountServiceAccountTokenForAgents bool
	// MaxPeerNodes if != 0 restricts number of peer nodes used as destinations for checks (nodes are selected randomly, but stable in this case).
	MaxPeerNodes int

AgentDeployConfig contains configuration for deploying the nwpd agent daemonset.
