Functions ¶

func Filename ¶

func Filename() string

Filename returns the filename consulted for standard configuration.

Types ¶

type Config ¶

type Config struct {
	Project, Instance string                           // required
	Creds             string                           // optional
	AdminEndpoint     string                           // optional
	DataEndpoint      string                           // optional
	CertFile          string                           // optional
	UserAgent         string                           // optional
	TokenSource       oauth2.TokenSource               // derived
	TLSCreds          credentials.TransportCredentials // derived
}

Config represents a configuration.

func Load ¶

func Load() (*Config, error)

Load loads a .cbtrc file. If the file is not present, an empty config is returned.

func (*Config) CheckFlags ¶

func (c *Config) CheckFlags(required RequiredFlags) error

CheckFlags checks that the required config values are set.

func (*Config) RegisterFlags ¶

func (c *Config) RegisterFlags()

RegisterFlags registers a set of standard flags for this config. It should be called before flag.Parse.

func (*Config) SetFromGcloud ¶

func (c *Config) SetFromGcloud() error

SetFromGcloud retrieves and sets any missing config values from the gcloud configuration if possible possible

type GcloudCmdTokenSource ¶

type GcloudCmdTokenSource struct {
	Command string
	Args    []string
}

func (*GcloudCmdTokenSource) Token ¶

func (g *GcloudCmdTokenSource) Token() (*oauth2.Token, error)

Token implements the oauth2.TokenSource interface

type GcloudConfig ¶

type GcloudConfig struct {
	Configuration struct {
		Properties struct {
			Core struct {
				Project string `json:"project"`
			} `json:"core"`
		} `json:"properties"`
	} `json:"configuration"`
	Credential GcloudCredential `json:"credential"`
}

func LoadGcloudConfig ¶

func LoadGcloudConfig(gcloudCmd string, gcloudCmdArgs []string) (*GcloudConfig, error)

LoadGcloudConfig retrieves the gcloud configuration values we need use via the 'config-helper' command

type GcloudCredential ¶

type GcloudCredential struct {
	AccessToken string    `json:"access_token"`
	Expiry      time.Time `json:"token_expiry"`
}

func (*GcloudCredential) Token ¶

func (cred *GcloudCredential) Token() *oauth2.Token

type RequiredFlags ¶

type RequiredFlags uint

const (
	ProjectRequired RequiredFlags = 1 << iota
	InstanceRequired
)

const NoneRequired RequiredFlags = 0

const ProjectAndInstanceRequired RequiredFlags = ProjectRequired | InstanceRequired
