Instead of searching the installed provider package directory for a
binary as we install it, we can lazily detect the executable as it is
required. Doing so allows us to separately report an invalid unpacked
package, giving the user more actionable error messages.
* tools/terraform-bundle: refactor to use new provider installer and
provider directory layouts
terraform-bundle now supports a "source" attribute for providers,
uses the new provider installer, and the archive it creates preserves
the new (required) directory hierarchy for providers, under a "plugins"
directory.
This is a breaking change in many ways: source is required for any
non-HashiCorp provider, locally-installed providers must be given a
source (can be arbitrary, see docs) and placed in the expected directory
hierarchy, and the unzipped archive is no longer flat; there is a new
"plugins" directory created with providers in the new directory layout.
This PR also extends the existing test to check the contents of the zip
file.
TODO: Re-enable e2e tests (currently suppressed with a t.Skip)
This commit includes an update to our travis configuration, so the terraform-bundle e2e tests run. It also turns off the e2e tests, which will fail until we have a terraform 0.13.* release under releases.hashicorp.com. We decided it was better to merge this now instead of waiting when we started seeing issues opened from users who built terraform-bundle from 0.13 and found it didn't work with 0.12 - better that they get an immediate error message from the binary directing them to build from the appropriate release.
Historically our logic to handle discovering and installing providers has
been spread across several different packages. This package is intended
to become the home of all logic related to what is now called "provider
cache directories", which means directories on local disk where Terraform
caches providers in a form that is ready to run.
That includes both logic related to interrogating items already in a cache
(included in this commit) and logic related to inserting new items into
the cache from upstream provider sources (to follow in later commits).
These new codepaths are focused on providers and do not include other
plugin types (provisioners and credentials helpers), because providers are
the only plugin type that is represented by a heirarchical, decentralized
namespace and the only plugin type that has an auto-installation protocol
defined. The existing codepaths will remain to support the handling of
the other plugin types that require manual installation and that use only
a flat, locally-defined namespace.
