InfluxDB on Traefik 2.0 is missing the user on the API callback

[killua99]

Do you want to request a feature or report a bug?

Bug

Did you try using a 1.7.x configuration for the version 2.0?

• Yes
• No

What did you do?

I'm trying to use influxdb as metric but the http API callback might has change, because it get a 403 user is require

The error log is quite simple, the user is missing, it might be because the API has change on the endpoing or what?

time="2019-09-28T00:20:55Z" level=error msg="Error while writing to InfluxDB: {\"error\":\"user is required to write to database \\\"db_influxdb\\\"\"}\n" metricsProviderName=influxdb

I've setup everything as the documentation said for docker.

What did you expect to see?

Just a normal entry on influxdb for metrics

What did you see instead?

An error on traefik log:

time="2019-09-28T00:20:55Z" level=error msg="Error while writing to InfluxDB: {\"error\":\"user is required to write to database \\\"db_influxdb\\\"\"}\n" metricsProviderName=influxdb

Closed by #5531.

Hi @killua99 , as you asked in the associated PR:

How this MR will fix the API callback? I was talking about the API callback the user is missing or at > least that's the error I get.

could you try your setup with the right casing for the options in Traefik:

traefik.yml:

...
metrics:
  influxDB:
    address: http://192.168.1.170:8086
    protocol: http
    database: db_influxdb
    username: irrelevant 
    password: irrelevantx2
...

and let us know here if it works for you please?

[killua99]

there's a way to compile this to be a docker image ? I'm running it with the latest image traefik:montdor or ... perhaps copy the Docker file, and build the image locally (that sometimes take ages with docker buildx) and try with that ?

[dduportal]

Hi @killua99 , there is no need to :) The scope of the pull request #5531 is only documentation: nothing was changed.

Initially, the documentation was mentioning the configuration item to be metrics.influxdb in lower case, which you did right.

But in fact, Traefik v2 is expecting the configuration item to be metrics.influxDB (with DB in upper case), so the pull request fixed the documentation.

Now what I'm asking to you is to ensure that, with the version of Traefik you have (2.0.0 or even 2.0.1) to edit your configuration file by changing influxdb: to influxDB: and re-create the stack. This should fix your issue, let us know.

oh yes, now it does connect. Thanks for the support
