This includes both the main documentation about the lock file itself and
changes to related documentation about Terraform commands that interact
with the lock file.
We will likely continue to update this first pass of documentation as we
get feedback and questions during the prerelease period.
We previously had this just stubbed out because it was a stretch goal for
the v0.13.0 release and it ultimately didn't make it in.
Here we fill out the existing stub -- with a minor change to its interface
so it can access credentials -- with a client implementation that is
compatible with the directory structure produced by the
"terraform providers mirror" subcommand, were the result to be published
on a static file server.
This new command is intended to make it easy to create or update a mirror
directory containing suitable providers for the current configuration,
producing a layout that is appropriate both for a filesystem mirror or,
if copied into the document root of an HTTP server, a network mirror.
This initial version is not customizable aside from being able to select
multiple platforms to install packages for.
Future iterations of this could include commands to turn the JSON index
generation on and off, or to instruct it to produce the unpacked directory
layout instead of the packed directory layout as it currently does. Both
of those options would make the generated directory unsuitable to be
a network mirror, but it would still work as a filesystem mirror.
In the long run this will hopefully form part of a replacement workflow to
terraform-bundle as a way to put copies of providers somewhere so we don't
need to re-download them every time, but some other changes will be needed
outside of just this command before that'd be true, such as adding support
for network and/or filesystem mirrors in Terraform Enterprise.
We have released the v0.12-oriented content to the website early in order
to support the beta process, but in some places we neglected to explicitly
mark features or content as being v0.12-only.
Here we add explicit markers to the main cases we've seen where readers
have reported confusion, along with some other tweaks in similar vein.
