Martin Atkins fdd992cfa7 planning: Build manage resource instance execgraph from planned change
The temporary placeholder code was relying only on the
DesiredResourceInstance object, which was good enough for proving that this
could work at all and had the advantage of being a new-style model with
new-style representations of the provider instance address and the other
resource instances that the desired object depends on.

But that isn't enough information to plan anything other than "create"
changes, so now we'll switch to using plans.ResourceInstanceChange as the
main input to the execgraph building logic, even though for now that means
we need to carry a few other values alongside it to compensate for the
shortcomings of that old model designed for the old language runtime.

So far this doesn't actually change what we do in response to the change
so it still only supports "create" changes. In future commits we'll make
the execGraphBuilder method construct different shapes of graph depending
on which change action was planned.

Key features

  • 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.

Nightly Builds

Nightly builds are available for testing the latest changes on main. These are experimental and not intended for production use. Each build is removed after 30 days.

Nightly builds can be found at https://nightlies.opentofu.org/nightlies. For those who want to automate with tooling, https://nightlies.opentofu.org/nightlies/latest.json will be kept up to date with the latest build information.
