Connecting to AWS Elasticsearch instance using Python

This is the correct way to connect to elasticsearch server using python:

es = Elasticsearch(['IP:PORT',])

Elasticsearch's constructor doesn't have the host nor the port parameters. The first parameter should be a list, where each item in the list can be either a string representing the host:

'schema://ip:port'

Or a dictionary with extended parameters regarding that host

{'host': 'ip/hostname', 'port': 443, 'url_prefix': 'es', 'use_ssl': True}

---

In your case you probably would like to use:

 client = Elasticsearch(['https://ec2-xx-xx-xxx-xxx.us-west-2.compute.amazonaws.com:9200'])

The port is redundant since you are using the deafult one, so you can use remove it
client = Elasticsearch(['https://ec2-xx-xx-xxx-xxx.us-west-2.compute.amazonaws.com'])

host = 'ec2-xx-xx-xxx-xxx.us-west-2.compute.amazonaws.com' #without 'https'
YOUR_ACCESS_KEY = ''
YOUR_SECRET_KEY = ''
REGION = 'us-west-2' #change to your region
awsauth = AWS4Auth(YOUR_ACCESS_KEY, YOUR_SECRET_KEY, REGION, 'es')

es = Elasticsearch(
    hosts=[{'host': host, 'port': 443}],
    http_auth=awsauth,
    use_ssl=True,
    verify_certs=True,
    connection_class=RequestsHttpConnection
)
print(es.info())
