Requests any URL, any given number of time with client timeout set to be exponentially high with each iteration.
Use the binary from the release page or container image adimania/exponential-backoff
git clone https://github.com/adimania/exponential-backoff.git
cd exponential-backoff
go build -tags netgo -a -v exponential.go # note that tags are important for static linking of net package
git clone https://github.com/adimania/exponential-backoff.git
cd exponential-backoff
docker build .
The exponential binary supports a couple of flags. If you miss the flags, appropriate defaults are in place so things should work smoothly.
# ./exponential -help
Usage of ./exponential:
-URL string
URL to open (default "https://httpbin.org/delay/3")
-iterations int
Number of attempts (default 3)
To attempt a GET request 5 times for https://httpbin.org/delay/8, execute the following
# ./exponential -URL https://httpbin.org/delay/8 -iterations 5
For Docker, execute
# docker run adimania/exponential-backoff /usr/local/bin/exponential -URL https://httpbin.org/delay/8 -iterations 5
Note that both -URL and -iterations flags are optional. The binary on release page is build for Linux and might not work for other environments. Please use docker container.
Yes. If the request succeeds, then the subsequent iternations are not executed. To override this behaviour comment line 40 and rebuild binary (and container).
