Your current platform and any other packages that might be available for The lockįile will therefore include checksums for both the package you installed for Of the signed checksums as valid as long as one checksum matches. That are signed with a cryptographic signature, Terraform will treat all If you install a provider from an origin registry which provides checksums There are two special considerations with the "trust on first use" model:
Run of terraform init encounters a non-matching package for the same Regulations, and then trust that Terraform will raise an error if a future In whatever way you choose or any way you are required to by relevant When you add a new provider for the first time you can verify it This checksum verification is intended to represent aĪpproach. If a particular terraform init call makes changes to the lock file, Terraform Will disregard the existing selections and once again select the newestĪvailable version matching the version constraint. The -upgrade option when you run terraform init, in which case Terraform Terraform will always re-select that version for installation, even if a If a particular provider already has a selection recorded in the lock file, Select the newest available version that matches the given version constraint,Īnd then update the lock file to include that selection. If a particular provider has no existing recorded selection, Terraform will When terraform init is working on installing all of the providers needed forĪ configuration, Terraform considers both the version constraints in theĬonfiguration and the version selections recorded in the lock file.
