Sending package to influx:

echo "cpu name=f age=1" | nc -u localhost 8089

Using postman I send request:

localhost:8086/query?q=SHOW DATABASES

It returns:
{ "results": [ { "statement_id": 0, "series": [ { "name": "databases", "columns": [ "name" ], "values": [ [ "_internal" ] ] } ] } ] }

Hi @rambo

You can set UDP with Docker by using:

docker run -p 8086:8086 -p 8089:8089/udp -e INFLUXDB_UDP_ENABLED=true influxdb:1.7.3
