Semantic can do semantic deep equality checks for core objects. Example: apiequality.Semantic.DeepEqual(aPod, aPodWithNonNilButEmptyMaps) == true Copied from https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/apis/core/helper/helpers.go#L92-L114

Functions

func AddOrUpdateDaemonPodTolerations

func AddOrUpdateDaemonPodTolerations(spec *corev1.PodSpec)

AddOrUpdateDaemonPodTolerations apply necessary tolerations to DaemonSet Pods, e.g. node.kubernetes.io/not-ready:NoExecute. Copied from https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/controller/daemon/util/daemonset_util.go#L47-L102

func AddOrUpdateTolerationInPodSpec

func AddOrUpdateTolerationInPodSpec(spec *corev1.PodSpec, toleration *corev1.Toleration) bool

AddOrUpdateTolerationInPodSpec tries to add a toleration to the toleration list in PodSpec. Returns true if something was updated, false otherwise. Copied from https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/apis/core/v1/helper/helpers.go#L290-L316

func NewPod

func NewPod(ds *appsv1.DaemonSet, nodeName string) *corev1.Pod

NewPod creates a new pod Copied from https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/controller/daemon/daemon_controller.go#L1238-L1293

func NodeShouldRunDaemonPod

func NodeShouldRunDaemonPod(node *corev1.Node, ds *appsv1.DaemonSet) (bool, bool)

NodeShouldRunDaemonPod checks a set of preconditions against a (node,daemonset) and returns a summary. Returned booleans are:

• shouldRun: Returns true when a daemonset should run on the node if a daemonset pod is not already running on that node.
• shouldContinueRunning: Returns true when a daemonset should continue running on a node if a daemonset pod is already running on that node.
