CloudFormation templates to deploy black.box Unzoner backend(s) into AWS

AWS account

done once per year to maintain free tier discount

create a free AWS account and login
grant AdministratorAccess policy to org-admin role for use by your master AWS account with maximum (12 hours) duration

load environment

See, environment-variables

install requirements

activate root Python virtualenv

./update-modules.sh

python3 -m venv venv

. venv/bin/activate

pip install --upgrade pip setuptools wheel

pip install --upgrade awscli

configure

check ~/.aws/config

[profile {{DNS_SUB_DOMAIN}}]
region = {{AWS_REGION}}
source_profile = default
role_arn = arn:aws:iam::<aws_account_id>:role/<admin-role>

package

check if bucket already exists

bucket=$(uuid)
aws s3 mb s3://${bucket}

custom resource provider

requires Docker and deactivation of root virtualenv

pushd cfn-generic-custom-resource/generic_provider \
