CLI needs internet access to download additional components

[jdavidheiser]

Describe the issue

When using the CLI to interact with Databricks Asset Bundles, it needs to fetch and install some Terraform libraries. This causes problems when installing the CLI in a Docker image and then using that CLI in an airgapped environment.

This is a re-raising of the issue brought up in #1238 (comment) since it's been a while since that was posted and I still have no idea when a solution will be available.

Steps to reproduce the behavior

• Install CLI
• block access to hasicorp.com
• try to run databricks bundle ...

Expected Behavior

I would expect to be able to install all transitive dependencies when running the installer, and not have them dynamically installed later.

Actual Behavior

I have to manually install and configure terraform, or use a standalone Docker image, which does not really fit with my workflow here.

OS and CLI version

NA

Is this a regression?

Long term we're planning to stop depending on downloaded terraform binary.

Short term, you can set up docker image by pre-downloading the needed binaries and setting up some environment variables. We do that in our own tests. See https://github.com/databricks/cli/blob/main/acceptance/install_terraform.py
