Martin Atkins cbfeb0fdc8 jsonconfig: Additional details about input variables
The JSON object describing an input variable can now include two additional
properties:

- "type" provides a JSON representation of the variable's type constraint,
  if one is set. Omitted if either there is no constraint declared at all
  or if it's set to "any", which are equivalent and both mean that the
  type is completely unconstrained.

  This uses the standard cty representation of a type constraint, which
  matches how OpenTofu already describes types in the provider protocol,
  in state snapshots, and in saved plan files.
- "required" directly represents whether callers are required to provide
  a value for the variable. This is technically redundant since it is
  set to true unless "default" is also set, but this avoids the need for
  consuming software to reimplement this rule and potentially allows us to
  make this rule more complicated/subtle in future if needed.

For some reason the documentation about the JSON configuration
representation did not previously mention the "variables" property at all,
so this adds documentation for both the new properties and the pre-existing
properties.

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.
