Functions

func GetConflictFreeLabels 

func GetConflictFreeLabels(labels []string) ([]string, error)

GetConflictFreeLabels validates Labels for conflict In swarm the duplicates for labels are removed so we only take same values here, no conflict values If the key-value is the same we will only take the last label

func MaskCredentials 

func MaskCredentials(rawURL string) string

MaskCredentials masks credentials that are in an URL.

func ParseGenericResources 

func ParseGenericResources(value []string) ([]swarm.GenericResource, error)

ParseGenericResources parses and validates the specified string as a list of GenericResource

func Reload 

func Reload(configFile string, flags *pflag.FlagSet, reload func(*Config)) error

Reload reads the configuration in the host and reloads the daemon and server.

func Validate 

func Validate(config *Config) error

Validate validates some specific configs. such as config.DNS, config.Labels, config.DNSSearch, as well as config.MaxConcurrentDownloads, config.MaxConcurrentUploads and config.MaxDownloadAttempts.

func ValidateMinAPIVersion 

func ValidateMinAPIVersion(ver string) error

ValidateMinAPIVersion verifies if the given API version is within the range supported by the daemon. It is used to validate a custom minimum API version set through DOCKER_MIN_API_VERSION.
