Constants

View Source 
const (
	ManagedPostgresStatusReady  = "ready"
	ManagedPostgresStatusFailed = "failed"
	ManagedPostgresStatusError  = "error"
)

Statuses a Managed Postgres cluster reports while provisioning. The API documents "failed" as the terminal failure status; "error" is declared too because the service behind it reports that spelling for the same state.

Variables

View Source 
var ErrFlapsGone = &FlapsError{ResponseStatusCode: http.StatusGone}

ErrFlapsGone is returned when the API reports a resource as gone (HTTP 410). Managed Postgres returns it for a cluster that has already been deleted.

var ErrFlapsNotFound = &FlapsError{ResponseStatusCode: http.StatusNotFound}

Functions

func GetErrorRequestID 

func GetErrorRequestID(err error) string

func GetErrorTraceID added in v0.1.5 

func GetErrorTraceID(err error) string

func IsNameTakenError added in v0.9.5 

func IsNameTakenError(err error) bool

IsNameTakenError reports whether err is a rejection of an app name that is already in use.

Prefer this over matching the error's text: it reads the status code the API sets, and falls back to the message only when there is no code at all. The fallback covers two cases and is not vestigial:

  • a client running against a Fly.io API that predates the status code, and
  • app creation that never went through the Machines API at all, such as the extension providers that create their apps over GraphQL, where nothing sets a status code in the first place.

Note what the fallback deliberately does not match: a collision that races past the validation and trips the database constraint instead is reported with a generic message covering every unique constraint the platform has, not just app names. Telling that one apart needs context only the server has, so the API classifies it there and reports it here as the name_taken code.

func Retry added in v0.1.19 

func Retry(ctx context.Context, op func() error) error

Types

func NewWithOptions 

func NewWithOptions(ctx context.Context, opts NewClientOpts) (*Client, error)

func (*Client) AcquireLease

func (*Client) AppNameAvailable added in v0.1.67 

func (f *Client) AppNameAvailable(ctx context.Context, name string) (bool, error)

AppNameAvailable reports whether name is free to use for a new app.

App names are a single global namespace, so a name can be taken by an app this client cannot see. The API does not hide that: it looks the name up globally and then refuses the read, so a name held by another organization comes back as a 403 and counts as taken just as much as an app we can read. Only a 404 means the name is free.

Any other failure is returned as-is, alongside a false that means "not available" rather than "taken", because such a failure says nothing either way about the name. That includes a 401, which is what an unauthenticated or unusable token gets: reporting it as "taken" would tell the caller their name is in use when the truth is that nobody asked the question successfully.
