influxdb-cli | Ruby CLI for InfluxDB | User Interface library

I'm trying to install an opencv2 for Docker container in my Raspberry Pi with the newest OS image.

Here is my Dockerfile

I am attempting to create a docker-compose file that will host three services. InfluxDB, Grafana, and a custom script in a customer Dockerfile that fills the database. I am having networking issues, and the custom script is not able to connect to the InfluxDB due to a connection refused error (shown below).

The interesting thing is, that when I remove the custom script service (called ads_agent) from my docker-compose file and either run that script from the localhost or even build and run that Dockerfile in its own container, it connects just fine.

My script reads an environment variable called KTS_TELEMETRY_INFLUXDB_URL which is used for the InfluxDB client's URL to connect to. I can use "http://localhost:8086" for the URL when I run just from my command line, that works. I use my local machine's LAN IP address when I wrap the script in a Docker container because to it, localhost would be just the container. But nonetheless, this works just fine.

From within my docker-compose, since all three services are on the same network, I'm using "http://influxdb:8086" since that host name should be bound to that service's network interface. And indeed it is, because Grafana is connecting just fine using that URL. Sadly, when I try this with the script, I get connection refused.

For the initial render, I have object date, which is an empty array. I then try to get data from an influxDB, but the get result isn't reflected by React with a re-render. The get function is calling in useEffect (you can see this in screenshots). I use typescript, and to avoid getting an error on the initial load (that data is an empty array of objects and it doesn't have a value property) I use the typescript syntax, but it still doesn't display the correct value. It doesn't display anything at all.

What could be the problem? In the last photo, we can see another way to display data without a question mark from typescript, but it doesn't work correctly either, even if the length of the array is greater than 0, it still doesn't display data[0].value.

Initial data:

Data after DB get:

Get the first element in array:

Browser result (before ':' we should see data[0].value):

Alternate way (when data isn't empty we should see the value of the first object in array):

I also show we code

I am trying to update all of our influxdb python queries, so that they are not vulnerable to sql injections.

To do this, I have read that you can use params with the query_api() and specifically with the query_data_frame() (https://medium.com/sekoia-io-blog/avoiding-injections-with-influxdb-bind-parameters-50f67e379abb)

The issue I am running into is that I can not figure out how to get my params to be passed into my queries. Below is an example of one of our queries:

I have the frontend of a web-app running on localhost:8080, and a docker container running an influxDB on localhost:8086. I have npm-installed influxdb-client-js (https://github.com/influxdata/influxdb-client-js) and created a file called db.ts containing this code (https://github.com/influxdata/influxdb-client-js/blob/master/examples/influxdb-1.8.ts) with my credentials.

Right now I just want to test if I can query the database at all, form the frontend. When I import db.ts into a vue-component to see if any data will appear in the browser-console, Cors policy is blocking the request:

Access to fetch at 'http://localhost:8086/api/v2/query?org=' from origin 'http://localhost:8080' has been blocked by cors policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I tried to create a vue.config.js-file, and proxying like this:

I am using Apache Zeppelin (0.9.0) and Scala (2.11.12). I want to pull some data out of a dataframe and store it to InfluxDB, later to be visualized in Grafana, and cannot figure it out. I'm trying a naive approach with a foreach loop. The idea is to iterate through all rows, extract the columns I need, create a Point object (from this InfluxDB client library), and either send it to InfluxDB or add it to a list and then send all the points in bulk, after the loop.

The dataframe looks like this:

I'm trying to query data from InfluxDBv2 (2.0.2) using python3. The query is in flux, it works well inside InfluxDB (it displays the data well). I've tried to executed inside the same VM (Ubuntu 18.04) and the host machine (Windows10 Jupyter python-kernel=python3).

I have a Node.js application that I am trying to get to query InfluxDB's cloud offering, I have set it up so I can write data fine now I need the query part. My data contains a few values - or will anyways - I have an elapsed time, service, and serviceID.

Here is my query when I output it before running it

I have a Lambda function that is designed to take a message from a SQS queue and then input a value called perf_value which is just an integer. The CloudWatch logs show it firing each time and logging Done as seen in the .then() block of my write point. With it firing each time I am still only seeing a single data point in InfluxDB Cloud. I can't figure out why it is only inputting a single value then nothing after that. I don't see a backlog in SQS and no error messages in CloudWatch either. I'm guessing it is a code issue or InfluxDB Cloud setup though I used defaults which you would expect to actually work for multiple data points
