Functions

func DefaultBool

func DefaultBool(b *bool, def bool) bool

DefaultBool returns the value of the bool pointer b if not nil, otherwise the default value specified.

func DefaultIP

func DefaultIP(i *net.IP, def string) string

DefaultIP returns the IP as string if not nil, otherwise the default value specified.

func DefaultInt64

func DefaultInt64(i *int64, def int64) int64

DefaultInt64 returns the value of the int64 pointer b if not nil, otherwise the default value specified.

func DefaultString

func DefaultString(s *string, def string) string

DefaultString returns the value of the string pointer s if not nil, otherwise the default value specified.

func EllipString

func EllipString(s string, maxLen int) string

EllipString truncates the string s with an ellipsis character if longer than maxLen.

func ForEachZone

func ForEachZone(zones []string, f func(zone string) error) error

ForEachZone executes the function f for each specified zone, and return a multierror.Error containing all errors that may have occurred during execution.

func GetInstancesAttachedToEIP

func GetInstancesAttachedToEIP(ctx context.Context, client *v2.Client, elasticIPID, zone string) ([]*v2.Instance, error)

func GetInstancesInSecurityGroup

func GetInstancesInSecurityGroup(ctx context.Context, client *v2.Client, securityGroupID string) ([]*v2.Instance, error)

func IsEmptyStringPtr

func IsEmptyStringPtr(s *string) bool

func IsInList

func IsInList(list []string, v string) bool

IsInList returns true if v exists in the specified list, false otherwise.

func NonEmptyStringPtr

func NonEmptyStringPtr(s string) *string

NonEmptyStringPtr returns a non-nil pointer to s if the string is not empty, otherwise nil.

func RandStringBytes

func RandStringBytes(n int) (string, error)

RandStringBytes Generate random string of n bytes

func SliceToMap

func SliceToMap(v []string) (map[string]string, error)

SliceToMap returns a map[string]string from a slice of KEY=VALUE formatted strings. This function is used to obtain a map[string]string from CLI flags, as the current CLI flags parsing module used (github.com/spf13/pflag) implements a "StringToString" type flag but doesn't support passing empty values, which we need in some cases (e.g. resetting labels).

func VersionIsNewer

func VersionIsNewer(old, new string) bool

VersionIsNewer returns true if new version has potential deprecation

func VersionMajor

func VersionMajor(version string) uint32

VersionMajor returns major part of a version number (given "x.y(.z)", returns "x"). If the input version is not in semver format, returns 0.

func VersionMinor

func VersionMinor(version string) uint32

VersionMinor returns minor part of a version number (given "x.y(.z)", returns "y"). If the input version is not in semver format, returns 0.

func VersionsAreEquivalent

func VersionsAreEquivalent(a, b string) bool

VersionsAreEquivalent returns true if new and old versions both have same major and minor numbers
