aws_s3_sidecar

Purpose

Run this container as a sidecar to other services in a deployment environment like an ECS cluster/service/task, K8S cluster/pod, etc. The container can be used to pull config files from S3 and expose them so that your other containers can access them through a shared volume without relying on persistent storage. This is useful for situations where you may be deploying someone else's images (like a vendor) and don't want to extend them and deal with hosting your own repos, etc. but you need to bring in configuration files or something similar to get them working.

Usage

Deploy the container in an environment where it inherits an IAM role (i.e. an ECS task role), or provide the environment variables necessary to get aws-cli to pick up the credentials. To specify what files to expose, set the following environment variables:

  • BUCKET should be the bucket you wish to retrieve the files from
  • FILES is a |-delimited list of files within the bucket you wish to be exposed. Their full key will be used

The files will be exposed in a volume in /opt, which you should then mount in to any other containers you wish to acccess the files.
