tfspiegel is a client that implements the Terraform network provider mirror protocol. I wrote it because I felt that terraform providers mirror was not flexible enough and I wanted to be able to mirror provider versions without needing to reference actual Terraform provider configurations.
- mirror to S3 (either AWS or S3-like such as Minio/Ceph) or local filesystem
- mirror complex semantic version ranges (ranges are specified using blang/semver syntax)
- only mirror what needs to be mirrored, i.e. missing file or wrong checksum
- attempt to loop and re-mirror providers on a set interval without needing to be run from cron
- mirror to Artifactory
- proper tests
- proper release process
- clean up user UX
- fix some error handling issues
- example Kubernetes manifests
- build with
make - use
config.yaml.exampleas a model for how to set it up - if using S3 storage, all authentication/region variables are expected to be provided via normal AWSCLI environment variables
- configure
.terraformrcaccording to the Hashicorp documentation
IMPORTANT: Terraform mandates the use of HTTPS for the network provider mirror.
