Elasticsearch

I want a way to actually upload datasets in elasticsearch, and there are things I cannot find a way to solve and the documents made me so much confused that I'm brain frozen!

What I have tried:

I used elasticsearch python package installed via pip and I'm using a Docker container to run a cluster of ElasticSearch. I want something like this:

from elasticsearch import Elasticsearch, helpers
import csv, datetime

# Password for the 'elastic' user generated by Elasticsearch
ELASTIC_PASSWORD = "*****************"

# Create the client instance
es = Elasticsearch(
    "https://localhost:9200",
    ca_certs="/home/couzhei/code/FastAPI-stacks/Paya/http_ca.crt",
    basic_auth=("elastic", ELASTIC_PASSWORD)
)

# This is almost pseudo code
for dataset in es.all_indices():
    print(dataset.name, dataset.created_at, dataset.size)
