Publishing data to existing InfluxDb with credentials

[mxturri]

I would like to configure the influx publisher agent to publish data to an existing InfluxDb instance that requires credentials and I was unable to provide the credentials to the underlying API.
Do you have suggestions or an example on how I could do that?
Thanks!

Hi @mxturri. That's not currently supported in the agent, but could be added. Just to confirm, what version of InfluxDB are you running?

(I'm also going to transfer this discussion to the ocs repo, which is where the code for the InfluxDB publisher agent is kept.)

[mxturri]

@BrianJKoopman Thanks for your quick reply, and thanks for moving this post to the OCS repo. I had just realized I posted in the wrong place.
We are currently using version 1.8.10 of the influxdb server.

[BrianJKoopman]

Great. Do you need any other arguments for the InfluxDB client (docs here) besides username and password?

I'm thinking we'd add the ability to read credentials from the environment variables or from file (if you want to use Docker secrets, for instance.)

[mxturri]

I think that adding the ability to provide username/password or even a token via environment variables or from a file would be perfect. And, for what it's worth, I am running OCS in kubernetes.

Perfect, yeah, that can be added for username/password. I'm not sure the Influx 1.x Python client supports tokens though.

We're working on getting #362 merged soon for support of Influx 2.x. The 2.x client library does support tokens.

And, for what it's worth, I am running OCS in kubernetes.

Neat! I'd be curious to hear how that experience has been.

Alright, this has been implemented in #432. You can now pass credentials via environment variable or file via:

• INFLUXDB_USERNAME
• INFLUXDB_PASSWORD
  or
• INFLUXDB_USERNAME_FILE
• INFLUXDB_PASSWORD_FILE

Examples are updated in the agent docs. This new Docker image has the new feature in it: v0.11.3-29-g4f04551

EDIT: SSL support was also added, see #430 (reply in thread).

Hi Brian,
Unfortunately I am not using docker. I am using kubernetes and I am a newbie at it.
I am trying to see what's possible. If you have suggestions, please don't hesitate to provide insight.
Thanks!

[BrianJKoopman]

Ah, no worries. I pushed a test image to Docker Hub here if that's useful: brianjkoopman/ocs:influx-ssl-test

[mxturri]

Brian,
thanks so much for all your help. I was able to use the image above and verify that I can publish to the influx database with the ssl options. Please let me know when these changes will be merged into simonsobs/ocs:latest
Thanks again for all your help and especially for your patience.

[BrianJKoopman]

Great to hear! The changes are in the simonsobs/ocs:v0.11.3-31-gb43fe13 image now. It won't be in simonsobs/ocs:latest until the next release. I don't really have a timeline for when that will be at the moment, but if you follow the repo you can be notified of that.

[mxturri]

Thanks Brian for all your help. Much appreciated.
I will start using the image above and follow the repository for updates and new releases.
Cheers!
