in_unix plugin does not work with --under-supervisor (permission denied with var/run/fluent/fluent.sock) #4333
Open
Description
Describe the bug
We run fluentd without any the command line option(automatically with --under-supervisor). the in_unix plugin didn't work because the socket file's permission was insufficient.
$ ls -l /var/run/fluent/fluent.sock
srwxr-xr-x 1 _fluentd _fluentd 0 Oct 26 08:27 /var/run/fluent/fluent.sock
To Reproduce
- Install fluent with the following command
# fluent-package 5 (LTS)
curl -fsSL https://toolbelt.treasuredata.com/sh/install-ubuntu-jammy-fluent-package5-lts.sh | sh
- add configuration
<source>
@type unix
path /var/run/fluent/fluent.sock
</source>
- restart fluentd with the following command
$ sudo systemctl restart fluentd.service
- The created
/var/run/fluent/fluent.sockfile can not be written
$ ls -l /var/run/fluent/fluent.sock
srwxr-xr-x 1 _fluentd _fluentd 0 Oct 26 08:27 /var/run/fluent/fluent.sock
Expected behavior
The permission should be srwxrwxrwx.
