Functions

func ParseDockerDaemonHost

func ParseDockerDaemonHost(defaultTCPAddr, defaultTLSHost, defaultUnixAddr, defaultAddr, addr string) (string, error)

ParseDockerDaemonHost parses the specified address and returns an address that will be used as the host. Depending of the address specified, will use the defaultTCPAddr or defaultUnixAddr defaultUnixAddr must be a absolute file path (no `unix://` prefix) defaultTCPAddr must be the full `tcp://host:port` form

func ParseKeyValueOpt

func ParseKeyValueOpt(opt string) (string, string, error)

ParseKeyValueOpt parses and validates the specified string as a key/value pair (key=value)

func ParseLink(val string) (string, string, error)

ParseLink parses and validates the specified string as a link format (name:alias)

func ParsePortRange

func ParsePortRange(ports string) (uint64, uint64, error)

ParsePortRange parses and validates the specified string as a port-range (8000-9000)

func ParseRepositoryTag

func ParseRepositoryTag(repos string) (string, string)

ParseRepositoryTag gets a repos name and returns the right reposName + tag|digest The tag can be confusing because of a port in a repository name.

Ex: localhost.localdomain:5000/samalba/hipache:latest
Digest ex: localhost:5000/foo/bar@sha256:bc8813ea7b3603864987522f02a76101c17ad122e1c46d790efc0fca78ca7bfb

func ParseTCPAddr

func ParseTCPAddr(tryAddr string, defaultAddr string) (string, error)

ParseTCPAddr parses and validates that the specified address is a valid TCP address. It returns a formatted TCP address, either using the address parsed from tryAddr, or the contents of defaultAddr if tryAddr is a blank string. tryAddr is expected to have already been Trim()'d defaultAddr must be in the full `tcp://host:port` form

func ParseUintList

func ParseUintList(val string) (map[int]bool, error)

ParseUintList parses and validates the specified string as the value found in some cgroup file (e.g. `cpuset.cpus`, `cpuset.mems`), which could be one of the formats below. Note that duplicates are actually allowed in the input string. It returns a `map[int]bool` with available elements from `val` set to `true`. Supported formats:

7
1-6
0,3-4,7,8-10
0-0,0,1-7
03,1-3      <- this is gonna get parsed as [1,2,3]
3,2,1
0-2,3,1

func ParseUnixAddr

func ParseUnixAddr(addr string, defaultAddr string) (string, error)

ParseUnixAddr parses and validates that the specified address is a valid UNIX socket address. It returns a formatted UNIX socket address, either using the address parsed from addr, or the contents of defaultAddr if addr is a blank string.

func PartParser

func PartParser(template, data string) (map[string]string, error)

PartParser parses and validates the specified string (data) using the specified template e.g. ip:public:private -> 192.168.0.1:80:8000
