S3 Bucket

Terraform can also store modules in an S3 bucket. To access the bucket you must have appropriate AWS credentials in your configuration or available via shared credentials or environment variables.

There are a variety of S3 bucket addressing schemes, most are documented in the S3 configuration. Here are a couple of examples:

jamtur01

#!/bin/bash

type terraform >/dev/null 2>&1 || { echo >&2 "I require terraform but it's not installed. Quitting sadly."; exit 1; }

REGION="us-east-1"
BUCKET="remote_state"
ENVIRONMENT=${PWD##*/}
STATE_FILE="terraform.tfstate"
ARGS=$*

* aws_route53_record.riemann_private: diffs didn't match during apply. This is a bug with Terraform and should be reported as a GitHub Issue.

My root partition mounted read only too. To fix, I ran:

blkid
to get the disk's new UUID, and then updated /etc/fstab with the new value:

cp /etc/fstab /run
vim /run/fstab 
mount --no-mtab --fstab /run/fstab -o remount,rw /
cp /run/fstab /etc
reboot
