A lifeline for when you lose your state, and go uhoh.
Attempts to reconstruct a terraform state from the environment by performing a three way diff and import.
Assumptions
- aws provider
- resources in the environment have some set of tags
Don't panic :-)
Create a resource group to identify extant things in the environment that were created by terraform.
tfresurrect init-group -g assetdb-sandbox -t "Env=sandbox" -t "App=AssetDB" -t "[email protected]"
let's look at the resources we are able to discover using tags
tfresurrect env-resources -g assetdb-sandbox
now let's look at the diff of things we can import
tfresurrect diff -g assetdb-sandbox -f settings.tfvars
in some cases we won't be able to fully import all the resources unless we specify mappings of terraform resources to physical resources manually. tfresurrect can generate a mapping file for us to fill in
tfresurrect gen-identity
we can pass the identity file to sync and diff commands via -i identify_file.json
and finally let's import missing resources
tfresurrect sync -g assetdb-sandbox -f settings.tfvar -i identity.json
