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>

Utilise configuration and profiles from the host.
