TERRAFORM SUPPORT

Manage Terraform Providers and Modules with Sonatype Nexus Repository

Terraform is a widely adopted infrastructure-as-code (IaC) tool used to define, provision, and manage cloud and on-premises infrastructure. Sonatype Nexus Repository supports Terraform by acting as a secure, reliable proxy for Terraform providers and modules — helping teams improve build performance, reduce external dependencies, and apply consistent access control to infrastructure artifacts.

Improve Reliability and Control with Terraform Repositories

Terraform relies on registries to retrieve providers and modules during terraform init and related workflows. By default, these assets are downloaded directly from registry.terraform.io, which can introduce availability, performance, and governance challenges at scale. Sonatype Nexus Repository addresses this by providing Terraform proxy repositories that cache Terraform providers and modules locally. This enables organizations to centralize Terraform dependencies, improve reliability, and apply enterprise controls while remaining fully compatible with the Terraform CLI.

Supported Features

Terraform Proxy Repositories

Create Terraform proxy repositories that cache providers and modules from registry.terraform.io to improve reliability and reduce external network dependencies.

Provider and Module Caching

Cache all Terraform provider binaries, module archives, checksums, and signatures to accelerate repeated runs and stabilize CI/CD pipelines.

Metadata Rewriting

Rewrite upstream Terraform metadata so provider and module download URLs point back to Nexus Repository, ensuring all traffic flows through your controlled endpoint.

Terraform CLI Compatibility

Fully compatible with Terraform CLI v0.13 and all 1.x releases across Linux, macOS, and Windows platforms.

Authentication with API Tokens

Secure Terraform access using URL-based user tokens, enabling authenticated downloads without embedding credentials in Terraform configurations.

Terraform Asset Classification

Automatically classify modules in Terraform with the correct validation, indexing, and processing to ensure repository integrity. 

Standardize IaC Workflows with Terraform Support

Managing Terraform dependencies through Sonatype Nexus Repository allows teams to bring infrastructure automation under the same operational controls used for application artifacts. By using a single repository platform to manage Terraform alongside other formats such as containers, Helm charts, and language packages, development teams can standardize workflows, centralize control, and reduce operational complexity across the SDLC. 

  • Improve Reliability and Performance

    Cache Terraform providers and modules locally to reduce latency and protect builds from upstream outages or rate limits.

  • Centralize Access Control

    Apply repository-level permissions to control who can download, publish, or delete Terraform artifacts.

  • Secure Infrastructure Delivery

    Protect Terraform artifacts with consistent validation, indexing, and classification to ensure repository integrity.

Frequently Asked Questions

What is Terraform?

Terraform is an infrastructure-as-code (IaC) tool developed by HashiCorp that enables teams to provision and manage infrastructure through declarative configuration files rather than manual provisioning. Using a declarative language called HashiCorp Configuration Language (HCL), it describes the desired state of cloud and on-premises resources and automatically creates or updates them to reflect the declarative state. 

Does Sonatype Nexus Repository support Terraform providers and modules?

Yes. Sonatype Nexus Repository offers full Terraform support for proxying and caching both providers and modules from registry.terraform.io.

Is Terraform support available in Community Edition?

Yes. Terraform proxy repositories are available in both Sonatype Nexus Repository Community Edition and Pro versions. 

Does this work with CI/CD pipelines?

Yes. Terraform support is fully compatible with CI/CD workflows, allowing modules in Terraform to be securely consumed in automated build and deployment pipelines. CI/CD systems can securely access Sonatype Nexus Repository using token-based authentication for automated environments.

Which Terraform versions are supported?

Sonatype Nexus Repository is compatible with Terraform versions CLI v0.13 and all 1.x releases.
