es-client 1.1.1

"Elasticsearch Client builder, complete with schema validation, and AWS boto-based authentication"

You may wonder why this even exists, as at first glance it doesn’t seem to make anything any easier than just using elasticsearch.Elasticsearch() to build a client connection. I needed to be able to reuse the more complex schema validation bits I was employing, namely:

• master_only detection

• AWS IAM credential collection via boto3.session.Session

• Elasticsearch version checking and validation, and the option to skip this.

• Configuration value validation, including file paths for SSL certificates, meaning:

  • No unknown keys or unacceptable parameter values are accepted

  • Acceptable values and ranges are established–and easy to amend, if necessary.

So, if you don’t need these, then this library probably isn’t what you’re looking for. If you want these features, then you’ve come to the right place.

Example Usage

from es_client import Builder

config = {
    'elasticsearch': {
        'master_only': True,
        'client': {
            'hosts': '10.0.0.123',
            'use_ssl': True,
            'ca_certs': '/etc/elasticsearch/certs/ca.crt',
            'username': 'joe_user',
            'password': 'password',
            'timeout': 60,
        }
    }
}

try:
    client = Builder(config).client
except:
    # Do exception handling here...

Additionally, you can read from a YAML configuration file:

---
elasticsearch:
  master_only: true
  client:
    hosts: 10.0.0.123
    use_ssl: true
    ca_certs: /etc/elasticsearch/certs/ca.crt
    username: joe_user
    password: password
    timeout: 60

from es_client import Builder
from es_client.exceptions import ConfigurationError
from es_client.helpers.utils import get_yaml

try:
    client = Builder(get_yaml('/path/to/es_client.yml').client
except:
    # Do exception handling here...

The same schema validations apply here as well.
