Functions ¶
Types ¶
type Checksum ¶
func HashByRevision ¶
HashByRevision returns the checksum and revision. The checksum is of the live keyspace at a particular revision. It is equivalent to performing a range request of all key-value pairs can computing a hash of the data. If revision is 0, the latest revision is checksumed, else revision is checksumed. The resulting hash is consistent particular revision in the presence of compactions; so long as the revions itself has not been compacted, the hash never changes.
type ConstraintOp ¶
type ConstraintOp int
const (
Equals ConstraintOp = iota
)
func (ConstraintOp) String ¶
func (co ConstraintOp) String() string
type FieldConstraint ¶
type FieldConstraint struct {
// contains filtered or unexported fields
}
func (*FieldConstraint) BuildFilter ¶
func (fc *FieldConstraint) BuildFilter() (*FieldFilter, error)
func (*FieldConstraint) String ¶
func (fc *FieldConstraint) String() string
type FieldFilter ¶
type FieldFilter struct {
*FieldConstraint
// contains filtered or unexported fields
}
FieldFilter filters according to a field constraint.
func (*FieldFilter) Accept ¶
func (ff *FieldFilter) Accept(ks *KeySummary) (bool, error)
type Filter ¶
type Filter interface {
Accept(ks *KeySummary) (bool, error)
}
Filter declares an interface for filtering KeySummary results.
func ParseFilters ¶
ParseFilters parses a comma separated list of '<field>=<value>' filters where each field is specified in golang template format, e.g. '.Value.metadata.namespace'.
type KeySummary ¶
type KeySummary struct {
Key string
Version int64
Value interface{}
TypeMeta *runtime.TypeMeta
Stats *KeySummaryStats
}
KeySummary represents a kubernetes object stored in etcd.
func ListKeySummaries ¶
func ListKeySummaries(filename string, filters []Filter, proj *KeySummaryProjection, revision int64) ([]*KeySummary, error)
ListKeySummaries returns a result set with all the provided filters and projections applied.
func (*KeySummary) ValueJson ¶
func (ks *KeySummary) ValueJson() string
ValueJson gets the json representation of a kubernetes object stored in etcd.
type KeySummaryProjection ¶
KeySummaryProjection declares which optional fields to include in KeySummary results.
type KeySummaryStats ¶
type KeySummaryStats struct {
VersionCount int
KeySize int
ValueSize int
AllVersionsKeySize int
AllVersionsValueSize int
}
KeySummaryStats provides high level statistics on a a particular kubernetes object stored in etcd.
type PrefixFilter ¶
type PrefixFilter struct {
// contains filtered or unexported fields
}
PrefixFilter filter by key prefix.
func NewPrefixFilter ¶
func NewPrefixFilter(prefix string) *PrefixFilter
func (*PrefixFilter) Accept ¶
func (ff *PrefixFilter) Accept(ks *KeySummary) (bool, error)
