Add influxdb module

[soebbing]

Hi everybody!

This is my first attempt at a devenv module, to add support for InfluxDB.

I'm looking forward to some feedback!

Two more things:

• I'd name it config instead of settings so it's consistent with the other modules
• we don't commit the lock file for examples

[soebbing]

Lock file has been removed and I changed settings to config (hopefully in the right place). 😅

I took the ElasticMQ as an example https://github.com/cachix/devenv/blob/main/src/modules/services/elasticmq.nix#L18 - I think, that might need some changing as well.

Seems like the test failed:

• influx --execute 'CREATE DATABASE devenv'
  Failed to connect to http://localhost:8086: Get "http://localhost:8086/ping": dial tcp [::1]:8086: connect: connection refused
  Please check your connection settings and ensure 'influxd' is running.

Test is fixed! I forgot to set the port for the cli-command and it worked on my machine, since another influx instance was running on that port 🤦

[soebbing]

At least I thought I had fixed the test. But I am unsure how to interpret these checks. InfluxDB seems to have been successful, but others failed?

Is it supposed to work on macOS? https://github.com/cachix/devenv/actions/runs/7248487703/job/19744543883?pr=903

[soebbing]

It should work on macOS (and I am using it right now). I do not see the warning: unknown setting 'ssl-cert-file' message locally, could be due to a difference in macOS version (I am on Sonoma 14.2).

Maybe the timeout was too short, I increased it to match the one in elasticMQ test https://github.com/cachix/devenv/blob/main/examples/elasticmq/.test.sh#L14

That seems to have done the trick! https://github.com/cachix/devenv/actions/runs/7250287690/job/19760416126
