OpenTofu Rules

Everything under //opentofu mirrors //terraform but binds to //opentofu:toolchain_type. Rule bodies are identical — only the resolved toolchain differs — so behavior stays in lockstep between the two engines. Data-only rules (opentofu_module, opentofu_provider, opentofu_provider_group) are literal aliases for their terraform_* counterparts, provided so an OpenTofu-only project never has to import a terraform_* symbol.

Public rules

• opentofu_binary — bazel run wrapper for any tofu subcommand.
• opentofu_module — alias for terraform_module.
• opentofu_provider — alias for terraform_provider.
• opentofu_provider_group — alias for terraform_provider_group.
• opentofu_test — runs OpenTofu's HCL native test framework.
• opentofu_validate_test — tofu validate as a Bazel test.
• opentofu_fmt_test — tofu fmt -check as a Bazel test.

Module extensions

• extensions — opentofu_toolchains.
