Add configuration option for terraform plugin dir

[cbuto]

Fixes #565.

I posed a question on the issue itself about testing but its probably better to have the conversation here:

I'm having a hard time figuring out the best way to implement a test that would be easy to maintain long term. Testing that the -plugin-dir option is actually working requires having pre-downloaded providers. I wrote a test that uses a fixture with a pre-downloaded provider locally but i don't think committing the actual provider binary to the repo is a viable solution.

Do you have any suggestions on how to implement an actual test for this?

Thanks!

Implementation LGTM, but would be nice to have an integration test. I think you can test this by doing the following:

• Take one of the terraform examples we have
• Create a temporary folder as the plugin dir
• Run terraform init without configuring plugin dir
• Move the plugin folder from the created .terraform folder to the temporary path
• Remove the .terraform folder
• Run terraform init with the plugin dir configured to the temporary path

That sounds reasonable, let me give that a shot! thanks!

@yorinasub17 I wrote up a test for it but its a bit weird since there's not much indication from the terraform init that it actually found providers in the plugin dir. The only thing I could find to differentiate between using pre downloaded providers and not was a string in the init output (unauthenticated):

TestInitPluginDir 2021-02-18T10:14:52-05:00 logger.go:66: - Installed hashicorp/null v3.0.0 (unauthenticated)

Here is the output from the test:

Thanks for adding the test! It mostly looks good. Had one minor nit around cleanup, and also have a suggestion for the concern around verifiability:

Perhaps we can run InitE with the PluginDir configured but before copying the plugins, and verify that it errors? That way we know the -plugin-dir is being passed given that it errors when the folder is empty, and passes when it is not. What do you think?

That's a great idea, definitely gives me more confidence that things are working as expected.

Have one more minor issue around cleanup, but other than that this LGTM! Will kick off the build after you address that and if that passes, we can merge this in.

Sorry for the delay in getting back to this. It looks like the tests are failing consistently, and only when run all together. I will have to investigate this to see what might be causing the concurrency issues, and will report back findings.

Alrightly no problem, let me know if there's something I can help investigate!

[cbuto]

rebased with master. Let me know if there's anything I can help with @yorinasub17!

[yorinasub17]

@cbuto apologies for the delay in getting back to this. I got busy with other work initiatives and took a long time for me to come back.

I finally got to the bottom of the test failures. In our CI environment we use terraform 0.14, and the plugin folder changed (from plugins to providers) with that version. I can reliably reproduce the test failure on tf14.

Can you update the test to attempt to copy over both .terraform/plugins and .terraform/providers?

@yorinasub17 No problem, I completely understand! Thanks for digging into this. I was always confused why terraform 0.13 called the directory plugins 😆 .

I updated the test to copy over both directories. I wonder if I should attempt to check the terraform version before doing the copy?

Anyway, the test passes now with both 0.13 and 0.14, let me know what you think:
