OptionalexponentiationExponentiation factor applied to the delay after each failed attempt. Default 2.
OptionalinitialInitial delay. A number is interpreted as milliseconds. Default 10 milliseconds.
OptionalmaxMaximum delay. A number is interpreted as milliseconds. Default 120_000 milliseconds.
Reconnect backoff policy. Between reconnect attempts the engine waits a jittered exponential delay: it starts at initialInterval, grows by exponentiationFactor per failed attempt, is capped at maxInterval, and resets after a connection stays up long enough to be considered stable. Intervals accept a Duration or a number of milliseconds.
The field names mirror the invocation and ingress retry policies. Note the tunnel reconnect loop is unbounded — there is no
maxAttempts; it redials forever until a connection succeeds or the tunnel is shut down.
