Custom Terraform provider

Hi,

I’m trying to run a Gitlab pipeline with Terraform. Using a Terraform AWS provider (Terraform registered) it works. However I also have in the Terraform files a custom provider that is not registered in the Terraform registry. On my local MAC, it works because I installed the provider locally.

When I try to run a Gitlab pipeline, it complains with an error and advises the following

In the latter case, the plugin must be installed manually by locating and
downloading a suitable distribution package and placing the plugin’s executable
file in the following directory:
terraform.d/plugins/linux_amd64

Can someone help me where I can find such suitable distribution package and how that works?
