|
||
|
|
--max-iteration-time duration How long to wait at most between iterations (default 1m0s)
|
||
|
|
-i, --max-iterations uint Maximum number of retries (0 = infinite)
|
||
|
|
-t, --max-total-time duration Deadline for overall executions (0 = infinite)
|
||
|
|
--min-iteration-time duration How long to wait before first retry (default 100ms)
