~/.aws/credentials under any circumstances. Since we never use this file in a Substrate-managed AWS organization, reading this file can only serve to “cross the streams” with a legacy AWS account.The upgrade process this month is much more involved that most. As such, we’ll talk in Slack about when you’re going to perform the upgrade to ensure support’s available in the moment.
Before upgrading Substrate, audit your Terraform modules for resources in global modules that aren’t from global AWS serivces by copying the following program to audit.sh in your Substrate repository and running sh audit.sh.
set -e
substrate root-modules |
grep "/global\$" |
while read DIRNAME
do
echo "$DIRNAME" >&2
terraform -chdir="$DIRNAME" state pull >"$DIRNAME/audit.tfstate"
grep -F ":us-east-1:" "$DIRNAME/audit.tfstate" || :
rm -f "$DIRNAME/audit.tfstate"
echo >&2
done
Every resource this program identifies needs to be modified before proceeding. The most likely modification is to add provider = aws.us-east-1 to resources in the Terraform code that manages them.
Block all your coworkers from making Terraform changes however you usually do (announcing in Slack, deactivating CI/CD jobs, taking state file locks, etc.) and move your global state files from us-east-1 to your default region by copying the following program to mv-state.sh in your Substrate repository and running sh mv-state.sh.
set -e
DEFAULT_REGION="$(cat "substrate.default-region")"
PREFIX="$(cat "substrate.prefix")"
if [ "$DEFAULT_REGION" = "us-east-1" ]
then exit # nothing to do
fi
eval $(substrate-assume-role -role="DeployAdministrator" -special="deploy")
substrate root-modules |
grep "/global\$" |
while read DIRNAME
do
echo "$DIRNAME" >&2
aws s3 cp "s3://$PREFIX-terraform-state-us-east-1/$DIRNAME/terraform.tfstate" "s3://$PREFIX-terraform-state-$DEFAULT_REGION/$DIRNAME/terraform.tfstate"
aws s3 rm "s3://$PREFIX-terraform-state-us-east-1/$DIRNAME/terraform.tfstate"
echo >&2
done
Once you’ve run this program, there’s a provider to thread through the tree of Terraform modules before you can upgrade to Substrate 2021.12.
Add the following four lines in the domain module stanzas in root-modules/*/*/*/global/main.tf:
providers = {
aws = aws
aws.us-east-1 = aws.us-east-1
}
Add the following three lines below aws = { in modules/*/global/versions.tf except modules/lambda-function/global/versions.tf, modules/substrate/global/versions.tf, and your own modules:
configuration_aliases = [
aws.us-east-1,
]
(I regret not being able to provide a patch(1) file for these operations but the contents of versions.tf post-Terraform 1.0 are too unpredictable to do so safely.)
Now you can upgrade Substrate. Don’t release your block just yet, though.
After upgrading Substrate:

I regret the complexity of this upgrade process but feel it is, on balance, less risky than attempting to hide all this motion behind automation. Thanks for your patience.

This release changes the interactive interface to substrate-bootstrap-network-account and substrate-create-admin-account to make them easier to run in CI. If you are automating these commands by providing yes and no answers on standard input, this release will break your automation; you should run these commands interactively first to see what’s changed. The details of what’s changed are listed in the usual format below.

This can mostly be considered a no-op but note that now Substrate commands may be also be invoked as substrate subcommand. This is not a deprecation notice for the original invocation style.-fully-interactive, -minimally-interactive, and -non-interactive to all Substrate commands. -fully-interactive is almost identical (see below) to the behavior of 2021.08 and earlier releases. -minimally-interactive is the new default and removes the incessant “is this correct? (yes/no)” dialogs, which I thought would be welcome but turned out to be annoying. -non-interactive will never prompt for input and will instead exit with a non-zero status if input is required.substrate-create-admin-account by providing yes and no answers on standard input, this change will break your automation; you should run this command interactively first to see what’s changed.substrate-create-admin-account and substrate-create-account to prevent errant creation of new AWS accounts (which are tedious to delete in case creation was a mistake) plus a new -create option to suppress that confirmation.cloudtrail:CreateTrail API.
