While trying to deploy a new infiniband radar stack to monitor our Infinband setup over docker swarm, the API container is failing with the following errors obtainable from docker service logs :

It seems like the API cannot connect to our influxDB service (which is working fine, and is currently used by other part of our monitoring stack) Based on the query in error, it seems to me that you try to authenticate on the influxDB API by using root as user and password (yikes for that also), which is not doable with influxDB v2 anymore, as you can only set a password that have at least 8 characters on the influx v1 authentication compatibility layer. Do you know what needs to be edited to modify the authentication parameters for influxDB ?
