README Highlight Issue #42, 2023: OpenTofu

In this week’s issue of README Highlight (#42, 2023), we are taking a look at the following project: OpenTofu. OpenTofu is an open-source tool for building, changing, and versioning infrastructure safely and efficiently. It can manage existing and popular service providers as well as custom in-house solutions.

The key features of OpenTofu are:

  • Infrastructure as Code: Infrastructure is described using a high-level configuration syntax, allowing it to be versioned and treated like any other code. It can also be shared and re-used.

  • Execution Plans: OpenTofu generates an execution plan before making any changes, showing what it will do when called. This helps avoid surprises and allows for better control over infrastructure manipulation.

  • Resource Graph: OpenTofu builds a graph of all resources and parallelizes the creation and modification of non-dependent resources. This ensures efficient infrastructure building and provides insight into dependencies.

  • Change Automation: Complex changesets can be applied to infrastructure with minimal human interaction. The execution plan and resource graph help operators understand what changes will be made and in what order, reducing potential errors.

The OpenTofu repository contains the OpenTofu Core, which includes the command line interface and the main graph engine. To learn more about compiling OpenTofu and contributing suggested changes, refer to the contributing guide. Bug reports and enhancement requests can also be submitted following the same guide.

If you find a vulnerability or potential vulnerability in OpenTofu, please follow the Security Policy for reporting it. The project uses the Mozilla Public License v2.0.
