Functions

func Backoff

func Backoff(baseDelay, maxDelay time.Duration, retries int) time.Duration

Backoff returns a value in [0, maxDelay] that increases exponentially with retries, starting from baseDelay.

func Clean

func Clean(ctx context.Context, r runner.Runner) error

Clean removes left-over containers, networks, and volumes from a previous run of the local builder. This happens when ctrl+c is used during a local build. Each cleaning is defined by a get command, a warning to print if the get command returns something, and a delete command to apply in that case.

func ParseSubstitutionsFlag

func ParseSubstitutionsFlag(substitutions string) (map[string]string, error)

ParseSubstitutionsFlag parses a substitutions string into a map.

func RefreshDuration

func RefreshDuration(expiration time.Time) time.Duration

RefreshDuration calculates when to refresh the access token. We refresh a bit prior to the token's expiration.

func SubstituteAndValidate

func SubstituteAndValidate(b *pb.Build, substMap map[string]string) error

SubstituteAndValidate merges the substitutions from the build config and the local flag, validates them and the build.

Types

type TokenTransport

type TokenTransport struct {
	Ts oauth2.TokenSource
}

TokenTransport is a RoundTripper that automatically applies OAuth credentials from the token source.

func (*TokenTransport) RoundTrip

func (t *TokenTransport) RoundTrip(req *http.Request) (*http.Response, error)

RoundTrip executes a single HTTP transaction, obtaining the Response for a given Request.
