It doesn't however support state locking, only if also configuring DynamoDB. -This extra configuration and complexity isn't attractive, and we can achieve similar outcomes by using the =local= backend and storing it properly. Even better than sending to S3 and setting up the proper revision headers is to just use a separate repository to keep it. +This extra configuration and complexity isn't attractive, and I can achieve similar outcomes by using the =local= backend and storing it properly. Even better than sending to S3 and setting up the proper revision headers is to just use a separate repository to keep it. Using the same repository would create an unwanted cyclic process where the repository pipeline commits in itself. All data stored on git is encrypted with [[https://www.agwa.name/projects/git-crypt/][git-crypt]], which means git isn't being actually used as a source code repository, but as a versioned filesystem database. + +By taking advantage of the sourcehut ecosystem, it was easier to setup the access of the pipeline to the ad-hoc Terraform backend. + +I created a repository called [[https://git.sr.ht/~euandreh/vps-state/][=vps-state=]] to store the encrypted =.tfstate= and =.tfplan= files. During the CI run, the pipeline creates new a =.tfplan= file and commits it into =vps-state=, and after applying the plan it updates the =.tfstate= file and adds this change to =vps-state=. |
