Short Description
Proxy used to sign requests for AWS managed Elasticsearch.
Full Description

aws-signing-proxy

aws-signing-proxy is a proxy service, written in go, for automatically signing requests made to AWS endpoints. It leverages the aws-sdk-go library to sign requests to arbitrary URLs in AWS. I wrote it to connect a kibana instance to an AWS Elasticsearch cluster using an IAM role instead of hard-coding IPs in the access policy. Other uses may exist.

Usage

export AWS_ACCESS_KEY_ID=<xxx>
export AWS_SECRET_ACCESS_KEY=<xxx>
export AWS_REGION=<xxx>
./aws-signing-proxy -target https://search-my-cluster.us-west-2.es.amazonaws.com

Notes, Tips

Signature Expired

If you see:

{"message":"Signature expired: 20160415T172935Z is now earlier than 20160415T174424Z (20160415T174924Z - 5 min.)"}

verify that the clock/time is in sync on the proxy host.

Kibana Forbidden index write

For AWS Elasticsearch, the built-in kibana populates the .kibana index. If you see:

ClusterBlockException[blocked by: [FORBIDDEN/8/index write (api)];]

try changing the kibana index setting to use a different index. The marcbachmann/kibana4 docker image allows you to change this easily by setting the KIBANA_INDEX environment variable.
