To use a custom provider in Scalr, there are just a few simple steps to make this work.

Prerequisites

The provider must have a linux_amd64 binary as that is the container type in Scalr
The provider must have executable permissions

How to add the provider

To use it in Scalr, the provider needs to be installed in a sub-folder of the Terraform workspace so that it will be uploaded to the remote workspace at the time of a run.
For Terraform configurations in VCS repos linked to workspaces in a Scalr remote backend, the Scalr provider must be added to the VCS repo. For Terraform configurations being run via the CLI the provider must be added to the local directory/folder where the Terraform configuration is held.

Follow these steps:

If working with a VCS based repo, clone or pull the repo locally.
Download the binary for linux_amd64 for the version you require, e,g, terraform-provider-name_1.0.0_linux_amd64.tar.gz
Copy terraform-provider-scalr to {workspace}/terraform.d/plugins/terraform-provider-name
For a VCS based repo, commit and push back to the repo.

Now when you run terraform init; terraform apply, or a run is triggered by pull request automation, the plugin will be automatically uploaded to the workspace.
