You have to try GitOps. It downloads and applies Kubernetes files for you.
Commit your Kubernetes files to Git, and your cluster will install them for you.
You only need a GitHub account, a token, and two minutes of time. You can also use Bitbucket, GitLab, or other services.

Terraform vs Ansible
You tell Terraform WHAT it should build.
- How many VMs?
- What VMs?
- What OS?
And Terraform will figure it out.
With Ansible, you tell HOW it should configure it.
- What software to install?
- How to change configs?
- What updates to install?
