A common pattern is to conditionally assign to "count"
in a resource in order to decide dynamically whether it
should be created. In that situation it's necessary to
refer to attributes of the resource using the splat
syntax, but historically we didn't show errors in output
expressions and so people "got away with" incorrect usage
in that context.
The intent of this warning is to catch
potentially-problematic usage of attributes on such
resources even if the count happens to be currently
set dynamically to 1, which would not generate the
error. Then the user can quickly locate and fix the
incorrect usage regardless of the current value.
Validation is the best time to return detailed diagnostics
to the user since we're much more likely to have source
location information, etc than we are in later operations.
This change doesn't actually add any detail to the messages
yet, but it changes the interface so that we can gradually
introduce more detailed diagnostics over time.
While here there are some minor adjustments to some of the
messages to improve their consistency with terminology we
use elsewhere.
The level of abstraction that needs the "svchost" is the Module, not the
FriendlyHost. Us the new method in the module package for registry
interaction.
The "not found" error should use the raw string directly from the config
source, but the existing method was adding the default registry if there
was no host indicated.
By wrapping the instruction portions in comments we can get a cleaner rendering of the issue if a user posts it without removing the instructions first.
The content is otherwise the same as before.
This is a genre of invalid output expression that we've seen quite
commonly while testing with 0.11.0-rc1, so we'll call it out specifically
in the upgrade guide and suggest how to fix it.
The differences between the implicit and explicit modes of passing
provider configurations between modules are significant enough to warrant
giving these approaches different names and describing them separately.
This also includes documentation of the current limitation discussed in
#16612, where explicit passing requires a proxy configuration block even
for a _default_ provider configuration, because that limitation is being
accepted for the 0.11.0 release to limit scope.
Now that we're expecting "credentials" blocks in the config (with auth
tokens for private module registries, etc) we should not print out the
config contents into the log, or else people will probably end up
accidentally disclosing their credentials when sharing debug output with
us, or will be reluctant to share debug output.
The provider name coming from ProvidedBy may be resolved if it only
exists in the state. Make sure to strip the module and provider
prefixes for the provider name when adding missing providers.
It's become apparent that passing in a provider config for an implicitly
used provider would be very useful. While the ProviderConfigTransformer
efficiently added providers to the graph, the algorithm was reversed
from what would be needed to allow overriding implicit providers.
Change the ProviderConfigTransformer to fist add all configured
provider, even if they are empty stubs. Then run through all providers
being passed in from the parent, and replace the provider nodes we
created with proxies, and add implicit proxies where none existed. The
extra nodes will then be pruned later.
