Functions

func ConvertServices 

func ConvertServices(v1Services map[string]*ServiceConfigV1) (map[string]*ServiceConfig, error)

ConvertServices converts a set of v1 service configs to v2 service configs

func GetServiceHash

func Interpolate 

func Interpolate(key string, data *interface{}, environmentLookup EnvironmentLookup) error

Interpolate replaces variables in a map entry

func InterpolateRawServiceMap 

func InterpolateRawServiceMap(baseRawServices *RawServiceMap, environmentLookup EnvironmentLookup) error

func IsValidRemote 

func IsValidRemote(remote string) bool

IsValidRemote checks if the specified string is a valid remote (for builds)

func MergeServicesV1 

func MergeServicesV1(existingServices *ServiceConfigs, environmentLookup EnvironmentLookup, resourceLookup ResourceLookup, file string, datas RawServiceMap) (map[string]*ServiceConfigV1, error)

MergeServicesV1 merges a v1 compose file into an existing set of service configs
