This has been replaced with an "Expressions" page.
Also includes a number of changes to Markdown style to conform to our
usual conventions, applied automatically by my editor while making these
changes.
It's been a while since we made any significant updates to this page.
The main theme of this revamp is to ensure that we highlight how to
provide "ambient credentials" for each of the module sources using the
standard mechanisms for each source type.
While there, I also attempted a general cleanup to highlight the main
cases and make this less like a detailed description of all of
go-getter's esoteric features, and did some general copy-editing to write
it in our usual documentation "voice".
When writing an example for a submodule, the example should be placed in
`examples/{example name}` instead of
`modules/{module name}/examples/{example name}`.
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.
The initial pass of this section had some remaining ambiguities, so this
is a second revision that attempts to use terminology more consistently
and to not some additional behaviors that were not described in the
initial version.
The modules mechanism has changed quite a bit for version 0.11 and so
although simple usage remains broadly compatible there are some
significant changes in the behavior of more complex modules.
Since large parts of this were rewritten anyway, I also took the
opportunity to do some copy-editing to make the prose on this page more
consistent with our usual editorial voice and to wrap the long
lines.
Terraform modules encapsulate their resources, and dependencies can only
be expressed through outputs, which wasn't clear to me in the existing
documentation. I'm hoping a small change will make that more explicit.
