We previously had all of the types and helpers for all kinds of backends
together in package backend. That kept things relatively simple, but it
also meant that the majority of backends that only deal with remote state
storage ended up still indirectly depending on the entire Terraform modules
runtime, configuration loader, etc, etc, which brings into scope a bunch
of external dependencies that the remote state backends don't really need.
Since backends that support operations are a rare exception, we'll move the
types and helpers for those into a separate package "backendrun", and
then the main package backend can have a much more modest set of types and,
more importantly, a modest set of dependencies on other packages in this
codebase.
This is part of an ongoing effort to reduce the exposure of Terraform Core
and CLI code to the remote backends and vice-versa, so that in the long
run we can more often treat them as separate for dependency maintenance
purposes.
* Implementation of structured logging.
These are the changes that enable the cloud backend to consume
structured logs and make use of the new plan renderer. This will enable
CLI-driven runs to view the structured output in the Terraform Cloud UI.
* Cloud structured logging unit tests
* Remove deferred logs logic, fix minor issues
Color formatting fixes, log type stop lists, default behavior for logs
that are unknown
* Use service disco path in redacted plan url
For non-interactive contexts, Terraform is typically executed with the flag -input=false.
However for runs that are not set to auto approve, the cloud integration will prompt a user for
approval input even with input being set to false. This commit enables the cloud integration to know
the value of the input flag and use it to determine whether or not to ask the user for input.
If -input is set to false and the run cannot be auto approved, the cloud integration will throw an error
stating run confirmation can no longer be handled in the CLI and that they must do so through the browser.
The cloud package intends to implement a new integration for
Terraform Cloud/Enterprise. The purpose of this integration is to better
support TFC users; it will shed some overly generic UX and architecture,
behavior changes that are otherwise backwards incompatible in the remote
backend, and technical debt - all of which are vestiges from before
Terraform Cloud existed.
This initial commit is largely a porting of the existing 'remote'
backend, which will serve as an underlying implementation detail and not
be a typical user-level backend. This is because to re-implement the
literal backend interface is orthogonal to the purpose of this
integration, and can always be migrated away from later.
As this backend is considered an implementation detail, it will not be
registered as a declarable backend. Within these changes it is, for easy
of initial development and a clean diff.
