Make default InfluxDB client support custom HTTP endpoints

[mattiasb]

Proposal:

Make it possible to connect to an InfluxDB instance running behind a reverse proxy with a custom subpath / endpoint with the default InfluxDB client influx.

Current behavior:

I have InfluxDB, Grafana and nginx running as docker containers in a test VM at 192.168.122.26.
InfluxDB is exposed at 192.168.122.26/influxdb/

I can issue a ping command with curl but I can't log in using influx:

$ curl -sL -I l http://192.168.122.26/influxdb/ping
HTTP/1.1 204 No Content
Server: nginx/1.14.0
Date: Thu, 20 Sep 2018 11:21:11 GMT
Content-Type: application/json
Connection: keep-alive
Request-Id: 4714b565-bcc7-11e8-8009-000000000000
X-Influxdb-Build: OSS
X-Influxdb-Version: 1.5.4
X-Request-Id: 4714b565-bcc7-11e8-8009-000000000000

$ influx -host 192.168.122.26/influxdb -port 80
Failed to connect to http://192.168.122.26%2Finfluxdb: parse http://192.168.122.26%2Finfluxdb/ping: invalid URL escape "%2F"
Please check your connection settings and ensure 'influxd' is running.

Desired behavior:

I'd like to be able to connect to a custom endpoint with influx. :)

Use case:

I'm just getting started with InfluxDB but I'd like to be able to test the database with influx as the server is set up now. I might go back to just exposing the server directly via its default port and no endpoint instead if necessary.

@Stale I'm still watching this and in need of this. AFAIK there is no workaround, so it's impossible to use the influx CLI to connect to such endpoints.

Is this still unavailable?

This is a common use case for people deploying influxdb using containers, like with docker stack or kubernetes.

Official Python client already have it:

https://github.com/influxdata/influxdb-python/blob/6baf7eee61e968c70d4c7f111e7179bc92a80e8d/influxdb/client.py#L62

• Documentation
• Issue
• Commit

Even the third party Async Client has it:

https://github.com/gusutabopb/aioinflux/blob/b3186627a5bc071be36dd91eb81c02b8f8c23943/aioinflux/client.py#L93

• Commit

And the official CLI doesn't? Seems pretty trivial change to me.

CLI has a path argument but it is unrelated:

https://docs.influxdata.com/influxdb/v1.7/tools/shell/#path

If you need a setup you may use the Docker stack attached:
influxdeploy.zip

Deploy stack with:

docker stack deploy --compose-file=stack.yml influx

Access InfluxDB with:

curl -L -i http://127.0.0.1:8000/my/custom/path/ping?verbose=true

Connect using Sync Python client with:

from influxdb import InfluxDBClient
client = InfluxDBClient(host='127.0.0.1', port=8000, path='/my/custom/path/')
client.ping()

So every few months the stale bot tries to auto-close valid and accepted issues, and we have to keep spamming them in order to keep them open...

I also have topic starter's problem!
I run influxdb in docker-compose as described here: https://towardsdatascience.com/get-system-metrics-for-5-min-with-docker-telegraf-influxdb-and-grafana-97cfd957f0ac
I setup nginx as reverse proxy for ssl connection and checking link failed!

influx -ssl -host myhost.com/influxdb -port 443
Failed to connect to https://myhost.com%2Finfluxdb:443
Please check your connection settings and ensure 'influxd' is running.

It spends a lot of time for understanding, that it works!
