Functions

func CapabilitiesMap 

func CapabilitiesMap(caps []string) map[string]bool

CapabilitiesMap normalizes the given capabilities and converts them to a map.

func ConvertKVStringsToMap 

func ConvertKVStringsToMap(values []string) map[string]string

ConvertKVStringsToMap converts ["key=value"] to {"key":"value"}

func ConvertKVStringsToMapWithNil 

func ConvertKVStringsToMapWithNil(values []string) map[string]*string

ConvertKVStringsToMapWithNil converts ["key=value"] to {"key":"value"} but set unset keys to nil - meaning the ones with no "=" in them. We use this in cases where we need to distinguish between 

FOO=  and FOO

where the latter case just means FOO was mentioned but not given a value

func ConvertPortToPortConfig 

func ConvertPortToPortConfig(
	port nat.Port,
	portBindings map[nat.Port][]nat.PortBinding,
) ([]swarm.PortConfig, error)

ConvertPortToPortConfig converts ports to the swarm type

func EffectiveCapAddCapDrop 

func EffectiveCapAddCapDrop(add, drop []string) (capAdd, capDrop []string)

EffectiveCapAddCapDrop normalizes and sorts capabilities to "add" and "drop", and returns the effective capabilities to include in both.

"CapAdd" takes precedence over "CapDrop", so capabilities included in both lists are removed from the list of capabilities to drop. The special "ALL" capability is also taken into account.

Note that the special "RESET" value is only used when updating an existing service, and will be ignored.

Duplicates are removed, and the resulting lists are sorted.

func NormalizeCapability 

func NormalizeCapability(cap string) string

NormalizeCapability normalizes a capability by upper-casing, trimming white space and adding a CAP_ prefix (if not yet present). This function also accepts the "ALL" magic-value, as used by CapAdd/CapDrop.

This function only handles rudimentary formatting; no validation is performed, as the list of available capabilities can be updated over time, thus should be handled by the daemon.

func ParseCPUs 

func ParseCPUs(value string) (int64, error)

ParseCPUs takes a string ratio and returns an integer value of nano cpus

func ParseEnvFile 

func ParseEnvFile(filename string) ([]string, error)

ParseEnvFile reads a file with environment variables enumerated by lines

“Environment variable names used by the utilities in the Shell and Utilities volume of IEEE Std 1003.1-2001 consist solely of uppercase letters, digits, and the '_' (underscore) from the characters defined in Portable Character Set and do not begin with a digit. *But*, other characters may be permitted by an implementation; applications shall tolerate the presence of such names.” -- http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html

As of #16585, it's up to application inside docker to validate or not environment variables, that's why we just strip leading whitespace and nothing more.

func ParseHost 

func ParseHost(defaultToTLS bool, val string) (string, error)

ParseHost and set defaults for a Daemon host string 

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

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 ReadKVEnvStrings 

func ReadKVEnvStrings(files []string, override []string) ([]string, error)

ReadKVEnvStrings reads a file of line terminated key=value pairs, and overrides any keys present in the file with additional pairs specified in the override parameter. If a key has no value, it will get the value from the environment.

func ReadKVStrings 

func ReadKVStrings(files []string, override []string) ([]string, error)

ReadKVStrings reads a file of line terminated key=value pairs, and overrides any keys present in the file with additional pairs specified in the override parameter

func ValidateDNSSearch 

func ValidateDNSSearch(val string) (string, error)

ValidateDNSSearch validates domain for resolvconf search configuration. A zero length domain is represented by a dot (.).

func ValidateEnv 

func ValidateEnv(val string) (string, error)

ValidateEnv validates an environment variable and returns it. If no value is specified, it obtains its value from the current environment

As on ParseEnvFile and related to #16585, environment variable names are not validated, and it's up to the application inside the container to validate them or not.

The only validation here is to check if name is empty, per #25099

func ValidateExtraHost 

func ValidateExtraHost(val string) (string, error)

ValidateExtraHost validates that the specified string is a valid extrahost and returns it. ExtraHost is in the form of name:ip where the ip has to be a valid ip (IPv4 or IPv6).

func ValidateHost 

func ValidateHost(val string) (string, error)

ValidateHost validates that the specified string is a valid host and returns it.

func ValidateIPAddress 

func ValidateIPAddress(val string) (string, error)

func ValidateLabel 

func ValidateLabel(val string) (string, error)

ValidateLabel validates that the specified string is a valid label, and returns it.

Labels are in the form of key=value; key must be a non-empty string, and not contain whitespaces. A value is optional (defaults to an empty string if omitted).

Leading whitespace is removed during validation but values are kept as-is otherwise, so any string value is accepted for both, which includes whitespace (for values) and quotes (surrounding, or embedded in key or value).

TODO discuss if quotes (and other special characters) should be valid or invalid for keys TODO discuss if leading/trailing whitespace in keys should be preserved (and valid) 

func ValidateLink(val string) (string, error)

ValidateLink validates that the specified string has a valid link format (containerName:alias).
