Constants

const (
	// DefaultConfigFileName denotes the default application configuration file name.
	DefaultConfigFileName = "fly.toml"
	// Config is versioned, initially, to separate nomad from machine apps without having to consult
	// the API
	NomadPlatform    = "nomad"

}

type Config

type Config struct {
	AppName     string                 `toml:"app,omitempty"`
	Build       *Build                 `toml:"build,omitempty"`
	HttpService *HttpService           `toml:"http_service,omitempty"`
	VM          *VM                    `toml:"vm,omitempty"`
	Definition  map[string]interface{} `toml:"definition,omitempty"`
	Path        string                 `toml:"path,omitempty"`
	Services    []api.MachineService   `toml:"services"`
	Env         map[string]string      `toml:"env" json:"env"`
	Metrics     *api.MachineMetrics    `toml:"metrics" json:"metrics"`
	// contains filtered or unexported fields
}

Config wraps the properties of app configuration.

func ConfigFromContext

func ConfigFromContext(ctx context.Context) *Config

ConfigFromContext returns the Config ctx carries.

func LoadConfig

func LoadConfig(ctx context.Context, path string, platformVersion string) (cfg *Config, err error)

LoadConfig loads the app config at the given path.

func NewConfig

func NewConfig() *Config

func (*Config) DeterminePlatform
