Inspired by aws-nuke and cloud-nuke.
This tool was created out of my personal frustration with cleaning up GCP projects.
But why?
Many reasons:
The behaviour of gcloud projects delete is to disable a project - pending a 30 day wait time for any resource removal. Sometimes, you want to just want to remove everything; e.g. SharedVPCs - gcloud project delete on service projects can cause "ghost subnets" on the Host project. Yes, you end up with undeletable subnets due to VM resources, and end up having to 'undelete' the gcp project. Google support's solution? Well ofcourse, "just don't do it" - https://cloud.google.com/vpc/docs/deprovisioning-shared-vpc.
Additionally, I've found Terraform destroy of some of my colleagues' wizard level terraform modules fail occasionally, so it's always neat to see what's not been deleted via a dryrun.

2019/12/23 13:53:33 -- Deletion complete for project test-nuke-123456 (dry-run: true) --
- Add removal of VPC, subnets, CloudDNS resources and SharedVPC associations
- Add option to cleanup peerings at connecting projects
- Add unit tests and create a pipeline for robust integration test cases
- DRY - unfortunately due to the lack of generics in Go, I feel much of the code feels replicated among resources, lets come up with an idiomatic solution
- More reliable Dependencies and errors - Currently each resource can supply a list of dependent resources to remove first, however this always work as planned,
- Add logging lib, colours and verbosity levels
- Add dry-run report creation
- Discuss behaviour of deleting projects in parallel - currently resources are deleted in parallel
- Add a small video clip of cli usage
- Add contributing guide
