No crash, it's only to monitore the docker container with the docker's healthcheck feature.

ok, is it possible you can use curl instead? many OS's/dists/docker bases already have curl, so it might be nicer than wget

[dgtlmoon]

tries=1 is also far too low

Done.

Currently not in standalone with your debian version. I use apt for it.

It's a wget feature. But the retry is on the healthcheck feature: https://docs.docker.com/engine/reference/builder/#healthcheck 3 retry by default.
