 * `--http-probe` - enables HTTP probing (disabled by default)
 * `--http-probe-cmd` - additional HTTP probe command [zero or more]
 * `--http-probe-cmd-file` - file with user defined HTTP probe commands
+* `--http-probe-retry-count` - number of retries for each HTTP probe (default: 5)
+* `--http-probe-retry-wait` - number of seconds to wait before retrying HTTP probe (doubles when target is not ready; default: 8)
+* `--http-probe-ports` - explicit list of ports to probe (in the order you want them to be probed; excluded ports are not probed!)
+* `--http-probe-full` - do full HTTP probe for all selected ports (if false, finish after first successful scan; default: false)
 * `--show-clogs` - show container logs (from the container used to perform dynamic inspection)
 * `--show-blogs` - show build logs (when the minified container is built)
 * `--remove-file-artifacts` - remove file artifacts when command is done (note: you'll loose autogenerated Seccomp and Apparmor profiles)
