Add support for .terraformrc

[Paulius0112]

Trying to initialise private terraform modules in gitlab fails with all currently available secrets in the chart. However, manually providing a .terraformrc file with content

  token = "<TOKEN>"
}```

works successfully. Could you please add support for the above described file?

Can you please elaborate on this?

Where does this file need to be?

https://developer.hashicorp.com/terraform/cli/config/config-file

This reads like its only for Terraform Cloud/Enterprise?

We as an example, host our Terraform Modules on the Terraform Enterprise Module Registry. This registry requires to authenticate with a valid token to be able pull modules during the terraform init stage.

Another use case is provider mirroring. We have a internal artifact location where we use the .terraformrc file to configure a mirror location to ensure that Terraform downloads providers from this artifact location instead of the public internet, e.g.:

disable_checkpoint = true

provider_installation {
    network_mirror {
        url = "https://example.internal/some-application/api/terraform/hashicorp/providers/"
    }
}

@Paulius0112 in newer versions of Terraform (>= 1.2.0), you can set an environment variable which is then used by TF TF_TOKEN_your_internal_module_registry_org. I have this in the secret I mount for my GitLab credentials.

Environment variables can be configured using the environment key:

helm-charts/charts/atlantis/values.yaml

Lines 418 to 420 in 6ff20ce

	environment: {}
	# environment:
	# ATLANTIS_DEFAULT_TF_VERSION: v1.2.9

.

Does this solves this issue?
