Logstash => influxdb authentication failed

[mibrahim (Mohamed Ibrahim Ali Ibrahim)]

I am trying to make my logstash report matrics to influxdb but i got authentication failed

Here is my config for logstash.conf:

input {
  exec {
    command => "echo 'Hello'"
    interval => 30
  }
}

output {
  influxdb {
    codec => json
    data_points => {}
    host => "influxdb2"
    port => 8086
    user => "admin"
    password => "adminPassword"
    db => "my-test-bucket"
    measurement => "my-logstash"
    retention_policy => "30days"
    use_event_fields_for_data_points => true
  }
  
  stdout { codec => rubydebug }
}

and here is my docker-compose.yml file with $ELK_VERSION=8.2.0 and $INFLUXDB_VERSION=2.2.0

version: '3.8'

services:

  logstash:
    build:
      context: logstash/
      args:
        ELK_VERSION: $ELK_VERSION
    volumes:

        source: ./logstash/config/logstash.yml
        target: /usr/share/logstash/config/logstash.yml
        read_only: true
      - type: bind

    depends_on:

  influxdb2:

      args:
        INFLUXDB_VERSION: $INFLUXDB_VERSION
    volumes:

    environment:

      - DOCKER_INFLUXDB_INIT_ORG=my-org

      - DOCKER_INFLUXDB_INIT_ADMIN_TOKEN=tokenValue
    restart: always
    ports:
      - 8083:8083
      - 8086:8086
      - 8088:8088
    privileged: true
    networks: [logstash-influx]


networks:
  logstash-influx:
    driver: bridge

and finally this is what i see in logstash logs:

[logstash.outputs.influxdb][main][01a059db918175277750b48ea961afe2cc3da4cb1ca2db4a7c55835b97214837] Authentication Error while writing to InfluxDB {:exception=>#<InfluxDB::AuthenticationError: > > > >
{"code":"unauthorized","message":"Unauthorized"}>}

{
"message" => "Hello\n",
"@timestamp" => 2022-05-21T03:46:17.408520Z,
"command" => "echo 'Hello'",
"host" => "c432d182d05e",
"@version" => "1"
}

I wonder why it fail in authentication and i am sure i am passing the correct username and password, any idea???
