Overview ¶
Package workload builds dataplane workloads. The Unbounded operator deploys them; the controller only observes and authenticates them.
Index ¶
Constants ¶
const ( DataplaneDaemonSetName = "racer-dataplane" PodNetworkDaemonSetName = "racer-dataplane-podnet" )
const DataplaneMemoryRequest = "1Gi"
DataplaneMemoryRequest is the default memory request for the dataplane container. It covers the fixed overhead (a checkpoint working set of up to 64 MiB by default, metadata, and runtime) plus the admission floors of a handful of I/O workers (roughly 115 MiB of byte budgets per worker), so the scheduler reserves a realistic baseline on every node.

Functions ¶
func DataplaneAffinity ¶ added in v0.17.0
DataplaneAffinity is the default node affinity of dataplane Pods. Workloads that must share nodes with the dataplane reuse it.
func DesiredDaemonSets ¶
DesiredDaemonSets builds steady-state placement, not a safe migration plan. The operator must additionally exclude occupied destination nodes until every source Pod, including terminating Pods, has disappeared.
func ManagedNames ¶
ManagedNames contains only the explicitly configured workload.
Types ¶
type Config ¶
type Config struct {
Cluster wire.ClusterID
Namespace string
ControlURL string
BootstrapTrustConfigMap string
DataplaneImage string
PeerPort uint16
HostNetwork bool
PodNetworkNodes []string
// Zero selects the automatic diagnostics port (9090, or 9091 when the peer
// port is 9090).
DiagnosticsPort uint16
DataplaneServiceAccount string
DaemonSetName string
}
Config contains only the inputs needed to build the dataplane DaemonSet. Controller limits, rotation policy, serving TLS, and durable state are independent.
func ConfigFromLookup ¶
ConfigFromLookup reads operator deployment wiring without loading or validating controller runtime configuration. Shared settings retain the same defaults.
type NodePlacement ¶ added in v0.17.0
type NodePlacement struct {
// Affinity carries only node affinity. Pod affinity and anti-affinity
// are relative to dataplane Pods, so a rule such as hostname
// anti-affinity against racer-dataplane would otherwise exclude the
// copying workload from every dataplane node.
Affinity *corev1.Affinity
NodeSelector map[string]string
Tolerations []corev1.Toleration
}
NodePlacement holds the node-level scheduling constraints of a dataplane Pod. Workloads that must run on every node that serves a cache, such as cache origins, copy it so they follow the dataplane, including user overrides applied to the live DaemonSet.
func PlacementOf ¶ added in v0.17.0
func PlacementOf(pod *corev1.PodSpec) NodePlacement
PlacementOf returns a deep copy of the node-level scheduling constraints of a Pod spec.
