Kapacitor 401 unautherized

[Mair]

Hi,

I'm trying to follow the getting started documentation. I followed the instructions and ran ./sandbox up
the web site start up OK but then when navigating to the "Hosts Lists" I get an "Unable to get hosts error"

Looking at the containers I see sandbox_kapacitor_1 has stopped.
looking at the logs I see the following

Hi!

What version of influxdb are you using? The sandbox is not working with influxdb of version greater or equal 2.

Check also that .env file doesn't have:

TELEGRAF_TAG=telegraf:latest
INFLUXDB_TAG=influxdb:latest
CHRONOGRAF_TAG=chronograf:latest
KAPACITOR_TAG=kapacitor:latest

You should have something like:

TELEGRAF_TAG=telegraf:latest
INFLUXDB_TAG=influxdb:1.8
CHRONOGRAF_TAG=chronograf:latest
KAPACITOR_TAG=kapacitor:latest

[Mair]

Thanks @gazon1,
This is a clean git pull off the repo following the instructions at get-started for the docker environment.
I can confirm the .env file to be as

TELEGRAF_TAG=telegraf:latest
INFLUXDB_TAG=influxdb:1.8
CHRONOGRAF_TAG=chronograf:latest
KAPACITOR_TAG=kapacitor:latest

Try to set up a user in influxdb in docker compose
The error says, that you're not authorised. Initially, influxdb has no users and so it couldn't connect

services:
  influxdb:
    # Full tag list: https://hub.docker.com/r/library/influxdb/tags/
    build:
      context: ./images/influxdb/

      args:
        INFLUXDB_TAG: ${INFLUXDB_TAG}
    image: "influxdb"
    volumes:
      # Mount for influxdb data directory
      - ./influxdb/data:/var/lib/influxdb
      # Mount for influxdb configuration

@gazon1 Tried that, same error although is you look at the log before that it says dial tcp 172.22.0.3:8086: connect: connection refused
I have checked, there is nothing else on that port

[gazon1]

Just found, that these command (DOCKER_INFLUXDB_...) in docker dompose may not be correct. Sometimes it doesn't create a user and database in influxdb. So try also to enter influxdb ./sandbox enter influxdb and initiate a user influx setup

But in this case, we should run a docker with kapacitor after setting up a influxdb user. So we should stop using docker compose

[gazon1]

So my guess is to check that you're running influxdb v < 2.0. Somehow, greater versions could be installed via docker cashe. I have no problems with version 1.8
You can ./sandbox enter influxdb and check version of influx there

[Mair]

No That's not it, It is 1.8. I find it disheartening that Its not working out of the box. The idea is to get a system up and running quickly so I can learn the technology, Now it seems I have to be an expert debugger before I can start to learn it. Its docker compose!... It should work the same in every environment

[Mair]

Tried this on a colleagues machine who also uses windows 10. Same result

[jmoeyersons]

Change this in your docker-compose file:

image: "influxdb:1.8" (add the :1.8)

This fixed my issue

[AminSaqi]

Also, change this in sandbox.bat file:

SET INFLUXDB_TAG=latest

to this:

SET INFLUXDB_TAG=1.8

You should remove created influxdb images, too. Even if it is tagged as influxdb:1.8. Finally, run sandbox up again.
