Simple Local AWS ElasticSearch Service proxy

Simple Local AWS ElasticSearch Service proxy

Easily utilise curl, Sense and other tools of your liking to get answers from your AWS hosted ElasticSearch Service while developing or debugging.

aws-es-proxy is a dead simple local proxy, that knows how to sign your requests and talk to a hosted AWS ElasticSearch Service.

Prequisities

• node >= v4.0.0 (ES6)
• Make sure your Elasticsearch domain is configured with access policy template "Allow or deny access to one or more AWS accounts or IAM users".
• Make sure your IAM credentials are discoverable:
  • via environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
  • via aws-cli authentication profile (defaults to profile default)
  • via instance profile on EC2 instance (with IAM role granting access to ES domain)

Usage

$ aws-es-proxy --port 9200 --profile default --region eu-west-1 <elastichsearch_url>

Fires up simple node HTTP proxy on port 9200 and signs your requests using aws-sdk using your default local AWS profile.

$ curl http://localhost:9200
{
  "status" : 200,
  "name" : "Superia",
  "cluster_name" : "123456789:search",
  "version" : {
    "number" : "1.5.2",
    "build_hash" : "20085dbc168df96c59c4be65f2999990762dfc6f",
    "build_timestamp" : "2016-04-20T15:51:59Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

With Docker

docker build -t aws-es-proxy .

Run and specify credentials via ENV variables.

docker run -it --rm -p 9210:9200 \
  -e AWS_ACCESS_KEY_ID=... \
  -e AWS_SECRET_ACCESS_KEY=... \
  aws-es-proxy -- <elasticsearch_url>
