Refresh kubeconfig when terraform state is lost #142

Closed alita1991 closed 10 months ago

alita1991 commented 10 months ago

Hi,

I have a scenario, where I need to refresh the local kubeconfig with the one from the target host. Right now, terraform does not offer a way to copy a remote file to the local host.

https://github.com/hashicorp/terraform/issues/3379

Is there a way to refresh the kubeconfig with the current module if I lose the tfstate or any other alternative solution that can be automated via terraform?

Thanks

Hi @alita1991, the only way I can found today is using the external provider which allows you to make what you want and expose any information to Terraform (like a shell script that cat | sed the kubeconfig remotely).

Hi, sadly, the external provider does not allow the user to SSH directly, I decided to pick a module developed by the community called terraform-provider-ssh, which does what I need.

If there is a better solution, please let me know, if not, you can close this ticket.

Thank you for sharing this, it will help the next ones who will ask this question. Unfortunately, I currently have a better way to do this with a Terraform module. I think the best way to handle this type of action (and others from different issues) is to migrate this module into a Terraform provider, which takes a lot more time to do and maintain.
