# FrostFS HTTP Gateway configuration file
|
|
|
|
This section contains detailed FrostFS HTTP Gateway configuration file description
|
|
including default config values and some tips to set up configurable values.
|
|
|
|
There are some custom types used for brevity:
|
|
|
|
* `duration` -- string consisting of a number and a suffix. Suffix examples include `s` (seconds), `m` (minutes), `ms` (
|
|
milliseconds).
|
|
|
|
|
|
# Reload on SIGHUP
|
|
|
|
Some config values can be reloaded on SIGHUP signal.
|
|
Such parameters have special mark in tables below.
|
|
|
|
You can send SIGHUP signal to app using the following command:
|
|
|
|
```shell
|
|
$ kill -s SIGHUP <app_pid>
|
|
```
|
|
|
|
Example:
|
|
|
|
```shell
|
|
$ ./bin/frostfs-http-gw --config config.yaml &> http.log &
|
|
[1] 998346
|
|
|
|
$ cat http.log
|
|
# ...
|
|
2022-10-03T09:37:25.826+0300 info frostfs-http-gw/app.go:332 starting application {"app_name": "frostfs-http-gw", "version": "v0.24.0"}
|
|
# ...
|
|
|
|
$ kill -s SIGHUP 998346
|
|
|
|
$ cat http.log
