type Filter ¶

type Filter struct {
    // Namespace is the namespace to apply to the inputs
    Namespace string `yaml:"namespace,omitempty"`

    // FsSlice contains the FieldSpecs to locate the namespace field
    FsSlice types.FsSlice `json:"fieldSpecs,omitempty" yaml:"fieldSpecs,omitempty"`

    // UnsetOnly means only blank namespace fields will be set
    UnsetOnly bool `json:"unsetOnly" yaml:"unsetOnly"`

    // SetRoleBindingSubjects determines which subject fields in RoleBinding and ClusterRoleBinding
    // objects will have their namespace fields set. Overrides field specs provided for these types, if any.
    // - defaultOnly (default): namespace will be set only on subjects named "default".
    // - allServiceAccounts: namespace will be set on all subjects with "kind: ServiceAccount"
    // - none: all subjects will be skipped.
    SetRoleBindingSubjects RoleBindingSubjectMode `json:"setRoleBindingSubjects" yaml:"setRoleBindingSubjects"`
    // contains filtered or unexported fields

func (Filter) Filter ¶

func (ns Filter) Filter(nodes []*yaml.RNode) ([]*yaml.RNode, error)

func (*Filter) WithMutationTracker ¶

func (ns *Filter) WithMutationTracker(callback func(key, value, tag string, node *yaml.RNode))

WithMutationTracker registers a callback which will be invoked each time a field is mutated
