Error in plugin: Got permission denied while trying to connect to the Docker daemon socket

Hello I'm hitting an issue while trying to setup InfluxDB with Telegraf
```
ls -ln /var/run/docker.sock | awk '{print $4}'

1
```

THIS IS MY telegraf docker-compose part
```
telegraf:
image: telegraf:1.19
container_name: telegraf
user: telegraf:1
volumes:
- ./telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:rw
- /var/run/docker.sock:/var/run/docker.sock
env_file:
- .env
depends_on:
- influxdb
```

and my error
```
telegraf | 2023-05-09T16:23:00Z E! [inputs.docker] Error in plugin:
Got permission denied while trying to connect to the Docker daemon socket
at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.21/containers/json?

dial unix /var/run/docker.sock: connect: permission denied
```

Start with the telegraf service in the provided docker-compose configuration and inspect how its user, group, and /var/run/docker.sock volume are set. Reproduce the inputs.docker startup and verify the Docker socket permissions. Done means Telegraf can query the Docker daemon without the permission-denied error.
