Simple test for checking if an EC2 instance or ECS task can access an | |
ElasticSearch domain. This was mainly lifted from the AWS documentation: | |
https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/es-request-signing.html#es-request-signing-python | |
To use this, first the requisite libraries must be available: | |
$ pip install -U \ | |
boto3 \ | |
elasticsearch \ | |
requests \ |
