Martin Atkins 2fda655ddf tofu: Warn if object literal includes unused attribute for input variable
We intentionally allow assigning object types with a superset of the
attributes included in an input variable's object type constraints because
it makes it possible to assign a whole object for which only some of the
attributes are relevant for one input variable but a different subset might
be relevant when the object value is used in a different part of the
configuration.

However, when the variable is defined using an object literal expression
there is no possible way an unexpected attribute could be useful in a
different part of the configuration, and so that's very very likely to be
a mistake rather than intentional. Therefore we'll generate a "linter-like"
warning in that case to help the author notice their mistake without
introducing any new "strict-mode" language features, or other complexity
that would be harder to maintain and evolve over time.

OpenTofu

OpenSSF Best Practices

OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu 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. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

  • Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.

  • Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

  • Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
