Test plan

• Setup test env by https://github.com/harvester/terraform-provider-harvester/wiki/PR-Test-Env-Setup for Reviwer
• Setup test env by https://github.com/harvester/terraform-provider-harvester/wiki/Use-the-master-head-docker-image-for-testing for Tester
• copy id_rsa.pub to test container

docker cp ~/.ssh/id_rsa.pub tf:/data/id_rsa.pub

• Create a test config file in the test container

vim main.tf

• apply

terraform apply -auto-approve

• ssh to the vm

LGTM, thanks.

LGTM, I saw duplicate ssh keys, it should be caused by the example tf file that contains both ssh_keys and templatefile config.
