Functions

func EmptyError

func EmptyError() string

EmptyError returns a string explanation of a "must not be empty" validation failure.

func InclusiveRangeError

func InclusiveRangeError(lo, hi int) string

InclusiveRangeError returns a string explanation of a numeric "must be between" validation failure.

func IsCIdentifier

func IsCIdentifier(value string) []string

IsCIdentifier tests for a string that conforms the definition of an identifier in C. This checks the format, but not the length.

func IsConfigMapKey

func IsConfigMapKey(value string) []string

IsConfigMapKey tests for a string that is a valid key for a ConfigMap or Secret

func IsDNS1035Label

func IsDNS1035Label(value string) []string

IsDNS1035Label tests for a string that conforms to the definition of a label in DNS (RFC 1035).

func IsDNS1123Label

func IsDNS1123Label(value string) []string

IsDNS1123Label tests for a string that conforms to the definition of a label in DNS (RFC 1123).

func IsDNS1123Subdomain

func IsDNS1123Subdomain(value string) []string

IsDNS1123Subdomain tests for a string that conforms to the definition of a subdomain in DNS (RFC 1123).

func IsDomainPrefixedPath added in v0.18.0

func IsDomainPrefixedPath(fldPath *field.Path, dpPath string) field.ErrorList

IsDomainPrefixedPath checks if the given string is a domain-prefixed path (e.g. acme.io/foo). All characters before the first "/" must be a valid subdomain as defined by RFC 1123. All characters trailing the first "/" must be valid HTTP Path characters as defined by RFC 3986.

func IsEnvVarName

func IsEnvVarName(value string) []string

IsEnvVarName tests if a string is a valid environment variable name.

func IsFullyQualifiedDomainName added in v0.17.0

func IsFullyQualifiedDomainName(fldPath *field.Path, name string) field.ErrorList

IsFullyQualifiedDomainName checks if the domain name is fully qualified. This is similar to IsFullyQualifiedName but only requires a minimum of 2 segments instead of 3 and accepts a trailing . as valid.

func IsFullyQualifiedName

func IsFullyQualifiedName(fldPath *field.Path, name string) field.ErrorList

IsFullyQualifiedName checks if the name is fully qualified. This is similar to IsFullyQualifiedDomainName but requires a minimum of 3 segments instead of 2 and does not accept a trailing . as valid. TODO: This function is deprecated and preserved until all callers migrate to IsFullyQualifiedDomainName; please don't add new callers.

func IsHTTPHeaderName

func IsHTTPHeaderName(value string) []string

IsHTTPHeaderName checks that a string conforms to the Go HTTP library's definition of a valid header field name (a stricter subset than RFC7230).

func IsInRange

func IsInRange(value int, min int, max int) []string

IsInRange tests that the argument is in an inclusive range.

func IsQualifiedName

func IsQualifiedName(value string) []string

IsQualifiedName tests whether the value passed is what Kubernetes calls a "qualified name". This is a format used in various places throughout the system. If the value is not valid, a list of error strings is returned. Otherwise an empty list (or nil) is returned.

func IsValidGroupID

func IsValidGroupID(gid int64) []string

IsValidGroupID tests that the argument is a valid Unix GID.

func IsValidIP

func IsValidIP(value string) []string

IsValidIP tests that the argument is a valid IP address.

func IsValidIPv4Address added in v0.17.0

func IsValidIPv4Address(fldPath *field.Path, value string) field.ErrorList

IsValidIPv4Address tests that the argument is a valid IPv4 address.

func IsValidIPv6Address added in v0.17.0

func IsValidIPv6Address(fldPath *field.Path, value string) field.ErrorList

IsValidIPv6Address tests that the argument is a valid IPv6 address.

func IsValidLabelValue

func IsValidLabelValue(value string) []string

IsValidLabelValue tests whether the value passed is a valid label value. If the value is not valid, a list of error strings is returned. Otherwise an empty list (or nil) is returned.

func IsValidPercent

func IsValidPercent(percent string) []string

IsValidPercent checks that string is in the form of a percentage

func IsValidPortName

func IsValidPortName(port string) []string

IsValidPortName check that the argument is valid syntax. It must be non-empty and no more than 15 characters long. It may contain only [-a-z0-9] and must contain at least one letter [a-z]. It must not start or end with a hyphen, nor contain adjacent hyphens.

Note: We only allow lower-case characters, even though RFC 6335 is case insensitive.

func IsValidPortNum

func IsValidPortNum(port int) []string

IsValidPortNum tests that the argument is a valid, non-zero port number.

func IsValidSocketAddr

func IsValidSocketAddr(value string) []string

IsValidSocketAddr checks that string represents a valid socket address as defined in RFC 789. (e.g 0.0.0.0:10254 or [::]:10254))

func IsValidUserID

func IsValidUserID(uid int64) []string

IsValidUserID tests that the argument is a valid Unix UID.

func IsWildcardDNS1123Subdomain

func IsWildcardDNS1123Subdomain(value string) []string
