Cloud-Init may not create a user literally called admin even though the configuration might be valid.

cat /var/log/cloud/cloud-init.log
cat /var/log/cloud/cloud-init-output.log

InfluxDBv2 UI behind Traefik Reverse-Proxy

Render your InfluxDB v2 UI behind a Traefik Reverse-Proxy

InfluxDBv2 does not provide any configuration flags / environment variables that can help render the UI as paths e.g. /influxdb. However, there is a potential way to circumvent this problem but using Host in Traefik.

NOTE: PLEASE DO NOT DEPLOY THIS STACK IN PRODUCTION.
