The Dockerfile on this folder creates a very lightweight image to create and automate RethinkDB backups to S3 buckets.
Intended to be ran as a command and scheduled by using some sort of cron, it will naturally die after completion.Don't
expect the container to stay up and running.
It basically runs rethinkdb dump against the rethinkdb host. There is only 2 environment variables you need to setup
for that to work, RETHINK_HOST, which is the rethink host and RETHINK_PASSWORD, which is the password.
The second part of the script is the backup upload to the assigned S3 bucket. For this you will need 3 environment
variables, BUCKET, AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
Be sure to have network access to the rethink cluster from wherever you are running the image, otherwise it will fail.
