Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

To compile the provider, run go install. This will build the provider and put the provider binary in the $GOPATH/bin directory.

To generate or update documentation, run go generate.

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run.

$ make testacc

Testing Locally

You can test the provider locally by using the provider_installation functionality.

For testing this provider, you can edit your ~/.terraformrc file with the following:

provider_installation {
  dev_overrides  {
    "cloudposse/utils" = "/path/to/your/code/github.com/cloudposse/terraform-provider-utils/"
  }

  # For all other providers, install them directly from their origin provider
  # registries as normal. If you omit this, Terraform will _only_ use
  # the dev_overrides block, and so no other providers will be available.
  direct {}
}

With that in place, you can build the provider (see above) and add a provider block:

required_providers {
    utils = {
      source = "cloudposse/utils"
    }
  }

Then run terraform init, terraform plan and terraform apply as normal.

$ terraform init

Warning: Provider development overrides are in effect

The following provider development overrides are set in the CLI configuration:
 - cloudposse/utils in /path/to/your/code/github.com/cloudposse/terraform-provider-utils

The behavior may therefore not match any released version of the provider and
applying changes may cause the state to become incompatible with published
releases.
