func IsHostname ¶
IsHostname checks the string is valid DNS hostname.
func IsInterfaceName ¶
IsInterfaceName validates a real network interface name.
func IsListenAddress ¶
IsListenAddress returns a validator for a listen address.
func IsMultipleOfUnit ¶

func IsNetworkAddress ¶
IsNetworkAddress validates an IP (v4 or v6) address string.
func IsNetworkAddressCIDR ¶
IsNetworkAddressCIDR validates an IP address string in CIDR format.
func IsNetworkAddressCIDRV4 ¶
IsNetworkAddressCIDRV4 validates an IPv4 address string in CIDR format.
func IsNetworkAddressCIDRV6 ¶
IsNetworkAddressCIDRV6 validates an IPv6 address string in CIDR format.
func IsNetworkAddressV4 ¶
IsNetworkAddressV4 validates an IPv4 address string.
func IsNetworkAddressV6 ¶
IsNetworkAddressV6 validates an IPv6 address string.
func IsNetworkMAC ¶
IsNetworkMAC validates an Ethernet MAC address. e.g. "00:00:5e:00:53:01".
Example ¶
package main
import (
"fmt"
"github.com/canonical/lxd/shared/validate"
)
func main() {
tests := []string{
"00:00:5e:00:53:01",
"02:00:5e:10:00:00:00:01", // too long
"00-00-5e-00-53-01", // invalid delimiter
"0000.5e00.5301", // invalid delimiter
"invalid",
"",
}
for _, v := range tests {
err := validate.IsNetworkMAC(v)
fmt.Printf("%s, %t\n", v, err == nil)
}
}
Output: 00:00:5e:00:53:01, true 02:00:5e:10:00:00:00:01, false 00-00-5e-00-53-01, false 0000.5e00.5301, false invalid, false , false
func IsNetworkMTU ¶
IsNetworkMTU validates MTU number >= 1280 and <= 16384. Anything below 68 and the kernel doesn't allow IPv4, anything below 1280 and the kernel doesn't allow IPv6. So require an IPv6-compatible MTU as the low value and cap at the max ethernet jumbo frame size.
func IsNetworkPort ¶
IsNetworkPort validates an IP port number >= 0 and <= 65535.
func IsNetworkPortRange ¶
IsNetworkPortRange validates an IP port range in the format "port" or "start-end".
func IsNetworkRange ¶
IsNetworkRange validates an IP range in the format "start-end".
func IsNetworkRangeV4 ¶
IsNetworkRangeV4 validates an IPv4 range in the format "start-end".
func IsNetworkRangeV6 ¶
IsNetworkRangeV6 validates an IPv6 range in the format "start-end".
func IsPCIAddress ¶
IsPCIAddress validates whether a value is a PCI address.
Example ¶
package main
import (
"fmt"
"github.com/canonical/lxd/shared/validate"
)
func main() {
tests := []string{
"0000:12:ab.0", // valid
"0010:12:ab.0", // valid
"0000:12:CD.0", // valid
"12:ab.0", // valid
"12:CD.0", // valid
"0000:12:gh.0", // invalid hex
"0000:12:GH.0", // invalid hex
"12:gh.0", // invalid hex
"12:GH.0", // invalid hex
"000:12:CD.0", // wrong prefix
"12.ab.0", // invalid format
"",
}
for _, v := range tests {
err := validate.IsPCIAddress(v)
fmt.Printf("%s, %t\n", v, err == nil)
}
}
Output: 0000:12:ab.0, true 0010:12:ab.0, true 0000:12:CD.0, true 12:ab.0, true 12:CD.0, true 0000:12:gh.0, false 0000:12:GH.0, false 12:gh.0, false 12:GH.0, false 000:12:CD.0, false 12.ab.0, false , false
func IsRequestURL ¶

"1,2,3", // valid
"1-3", // valid
"1-3,4-6", // valid
"1-3,4", // valid
"abc", // invalid syntax
"1-", // invalid syntax
"1,", // invalid syntax
"-1", // invalid syntax
",1", // invalid syntax
"1,2,3,3", // invalid: Duplicate CPU
"1-2,2", // invalid: Duplicate CPU
"1-2,2-3", // invalid: Duplicate CPU
}
for _, t := range tests {
err := validate.IsValidCPUSet(t)
fmt.Printf("%v\n", err)
}
}
Output: <nil> <nil> <nil> <nil> <nil> Invalid CPU limit syntax Invalid CPU limit syntax Invalid CPU limit syntax Invalid CPU limit syntax Invalid CPU limit syntax Cannot define CPU multiple times Cannot define CPU multiple times Cannot define CPU multiple times
func IsX509Certificate ¶
IsX509Certificate checks if the value is a valid x509 PEM Certificate.
func Optional ¶
Optional wraps Required() function to make it return nil if value is empty string.
Example ¶
package main
import (
"fmt"
"github.com/canonical/lxd/shared/validate"
)
func main() {
tests := []string{
"",
"foo",
"true",
}
for _, v := range tests {
f := validate.Optional()
fmt.Printf("%v ", f(v))
f = validate.Optional(validate.IsBool)
fmt.Printf("%v\n", f(v))
}
}
Output: <nil> <nil> <nil> Invalid value for a boolean "foo" <nil> <nil>
func ParseNetworkVLANRange ¶
ParseNetworkVLANRange parses a VLAN range in the form "number" or "start-end". Returns the start number and the number of items in the range.
func ParseUint32Range ¶
ParseUint32Range parses a uint32 range in the form "number" or "start-end". Returns the start number and the size of the range.
func Required ¶
Required returns function that runs one or more validators, all must pass without error.
Example ¶
package main
import (
"fmt"
"github.com/canonical/lxd/shared/validate"
)
func main() {
tests := []string{
"",
"foo",
"true",
}
for _, v := range tests {
f := validate.Required()
fmt.Printf("%v ", f(v))
f = validate.Required(validate.IsBool)
fmt.Printf("%v\n", f(v))
}
