Hello, I'm running Influxdb in docker container and trying to connect from logstash which is running locally.
I've enabled the influxdb-logstash plugin to connect to influxdb
```
output {
stdout {
codec => rubydebug
}
influxdb{
codec => json
host => "127.0.0.1:8086"
db => "influxtest"
user => "admin"
password => "admin"
measurement => "requests"
retention_policy => "two_weeks"
send_as_tags => ["stage","eventType","appId"]
use_event_fields_for_data_points => true
}
}
```
Here's the docker-compose file used to run influxDB in container
```
version: "2"
services:
grafana:
image: grafana/grafana
container_name: grafana
restart: always
ports:
- 3000:3000
networks:
- monitoring
volumes:
- grafana-volume:/var/lib/grafana
influxdb:
image: influxdb
container_name: influxdb
restart: always
ports:
- 8086:8086
networks:
- monitoring
volumes:
- influxdb-volume:/var/lib/influxdb
environment:
INFLUXDB_DB: influxtest
INFLUXDB_USER: test
INFLUXDB_USER_PASSWORD: test
INFLUXDB_ADMIN_ENABLED: "true"
INFLUXDB_ADMIN_USER: admin
INFLUXDB_ADMIN_PASSWORD: admin
networks:
monitoring:
volumes:
grafana-volume:
external: true
influxdb-volume:
external: true
```
Here's the stacktrace in logstash logs:

Any clue if thus a connection error or some config that i misplaced ?
