Config holds all service configuration loaded from environment variables.

func DefaultConfig

func DefaultConfig() Config

DefaultConfig returns the standard defaults shared by all entry points.

func ExtensionDefaults

func ExtensionDefaults() Config

ExtensionDefaults returns defaults for the Lambda Extension entry point. Port 9090 (avoids conflict with host Lambda), health disabled.

func Load

func Load(defaults *Config, opts Options) (*Config, error)

Load reads configuration from environment variables with the given options. The config starts from the provided defaults, then env vars override.

func (*Config) SAKeyJSON

func (c *Config) SAKeyJSON() ([]byte, error)

SAKeyJSON returns the SA key JSON content, reading from file if necessary.

type Options

type Options struct {
	// Prefix for env var names (e.g., "GGS_" reads GGS_PORT instead of PORT).
	Prefix string
}

Options controls how config is loaded. Different entry points pass different options.
