We late-reorganized this into the "Module Development" subsection, but
forgot to update the actual link in the navbar, so it was still linking
to its old location.
Since this is only a minor release there isn't any super-significant
upgrade guide content this time, but I've used this page to elaborate on
some of the upgrade notes already recorded in the Terraform Changelog, to
give additional context if needed to the hopefully-small number of users
that these changes will directly effect during upgrading.
As explained in the changes: The 'enhanced' backend terminology, which
only truly pertains to the 'remote' backend with a single API (Terraform
Cloud/Enterprise's), has been found to be a confusing vestige which need
only be explained in the context of the 'remote' backend.
These changes reorient the explanation(s) of backends to pertain more
directly to their primary purpose, which is storage of state snapshots
(and not implementing operations).
That Terraform operations are still _implemented_ by the literal
`Backend` and `Enhanced` interfaces is inconsequential a user of
Terraform, an internal detail.
Apologies for not creating an issue first but it seemed like a simple docs change.
`apt install terraform` requires the `apt update` before terraform can be installed.
When migrating from an explicit local backend to Terraform Cloud, we ask
if you want to migrate the state. If there is no state to migrate we
should not ask if they want to migrate the emptiness.
When going from a local backend to Terraform Cloud, if you skip the
`terraform init` and run `terraform apply` this will give the user more
clear instructions.
When terraform detects that a user has no workspaces that map to their current configuration, it will prompt the user to create a new workspace and enter a value name. If the user ignores the prompt and exits it, the legacy backend (terraform.tfstate) will be left in a awkward state:
1. This saved backend config will show a diff for the JSON attributes "serial", "tags" and "hash"
2. "Terraform workspace list" will show an empty list
3. "Terraform apply" will run successfully using the previous workspace, from the previous config, not the one from the current saved backend config
4. The cloud config is not reflective of the current working directory
Solution: If the user exits the prompt, the saved backend config should not be updated because they did not select a new workspace. They are back at the beginning where they are force to re run the init cmd again before proceeding with new changes.
Previously we ended up losing all of the error message detail produced by
the registry address parser, because we treated any registry address
failure as cause to parse the address as a go-getter-style remote address
instead.
That led to terrible feedback in the situation where the user _was_
trying to write a module address but it was invalid in some way.
Although we can't really tighten this up in the default case due to our
compatibility promises, it's never been valid to use the "version"
argument with anything other than a registry address and so as a
compromise here we'll use the presence of "version" as a heuristic for
user intent to parse the source address as a registry address, and thus
we can return a registry-address-specific error message in that case and
thus give more direct feedback about what was wrong.
This unfortunately won't help someone trying to install from the registry
_without_ a version constraint, but I didn't want to let perfect be the
enemy of the good here, particularly since we recommend using version
constraints with registry modules anyway; indeed, that's one of the main
benefits of using a registry rather than a remote source directly.
The HashiCorp APT server supports several distro releases that were not in this list,
leading to a false impression that they aren't supported.
Note, Ubuntu has a new release twice a year, so periodic maintenance
is needed here.
The `root_module.resources[].sensitive_values` key in the example output was incorrectly named and clashed with the regular `root_module.resources[].values` key.
Object values returned from providers have their attributes marked as
sensitive based on the provider schema. This was not fully implemented
for nested attribute types, which is corrected in this commit.
Resource instances removed from the configuration would previously use
the implied provider address. This is correct for default providers, but
incorrect for those from other namespaces or hosts. The fix here is to
use the stored provider config if it is present.
