Functions

func ConvertServices added in v0.3.0 

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

GetServiceHash computes and returns a hash that will identify a service. This hash will be then used to detect if the service definition/configuration have changed and needs to be recreated.

func Interpolate 

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

Interpolate replaces variables in a map entry

func InterpolateRawServiceMap added in v0.4.0 

func InterpolateRawServiceMap(baseRawServices *RawServiceMap, environmentLookup EnvironmentLookup) error

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

func IsValidRemote added in v0.3.0 

func IsValidRemote(remote string) bool

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

func Merge added in v0.3.0 

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 added in v0.3.0 

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 added in v0.3.0 

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

Types

type Config added in v0.3.0 

type Config struct {
	Version  string                 `yaml:"version,omitempty"`
	Services RawServiceMap          `yaml:"services,omitempty"`
	Volumes  map[string]interface{} `yaml:"volumes,omitempty"`
	Networks map[string]interface{} `yaml:"networks,omitempty"`
}

Config holds libcompose top level configuration

func CreateConfig added in v0.4.0 

func CreateConfig(bytes []byte) (*Config, error)

CreateConfig unmarshals bytes of a YAML manifest file and returns a new Config. Initialize any defaults that can't be parsed (but are optional) across various file formats. Most of these can remain unused.

This function only handles parsing YAML in the general case. Any other file format validation should be handled by the caller.
