DevOps started out as "Agile Systems Administration". In 2008, at the Agile Conference in Toronto, Andrew Shafer posted an offer to moderate an ad hoc "Birds of a Feather" meeting to discuss the topic of "Agile Infrastructure". Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing

CloudFormation -> Terraform Import Helpers

I wrote these scripts to help faciliate batch import of our CloudFormation templates into Terraform Configuration.

region-batch.sh

This script is a light wrapper around batch.sh. It simply iterates over the list of regions provided, exports expected variables, creates required directories, and calls batch.sh.

BASE_DIR=/path/to/dir EXCLUDE_REGEX="(some-stack-production|some-stack-staging)" ./region-batch.sh us-east-1 us-west-1
