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 GetServiceHash(name string, config *ServiceConfig) string

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

InterpolateRawServiceMap replaces varialbse in raw service map struct based on environment lookup

func IsValidRemote 

func IsValidRemote(remote string) bool

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

func Merge 

func Merge(existingServices *ServiceConfigs, environmentLookup EnvironmentLookup, resourceLookup ResourceLookup, file string, bytes []byte, options *ParseOptions) (string, map[string]*ServiceConfig, map[string]*VolumeConfig, map[string]*NetworkConfig, error)

Merge merges a compose file into an existing set of service configs

func MergeServicesV1 

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

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

func MergeServicesV2 

func MergeServicesV2(existingServices *ServiceConfigs, environmentLookup EnvironmentLookup, resourceLookup ResourceLookup, file string, datas RawServiceMap, options *ParseOptions) (map[string]*ServiceConfig, error)

MergeServicesV2 merges a v2 compose file into an existing set of service configs
