func FromFile ¶
FromFile returns config file with `name` read from `fileHandler` by parsing it as YAML. You should prefer config.New to read env vars and validate config in a consistent manner.
func New ¶ added in v2.3.0
New creates a new config by: 1. Reading config file via provided fileHandler from file with name. 2. Read secrets from environment variables. 3. Validate config.

func (*Config) GetProvider ¶
func (c *Config) GetProvider() cloudprovider.Provider
GetProvider returns the configured cloud provider.
func (*Config) HasProvider ¶
func (c *Config) HasProvider(provider cloudprovider.Provider) bool

func (c *Config) UpdateMeasurements(newMeasurements Measurements)
UpdateMeasurements overwrites measurements in config with the provided ones.
type Digests ¶ added in v2.5.0
type Digests = idkeydigest.IDKeyDigests
