kamus VS terraform-controller

I tried using the idea at https://stackoverflow.com/questions/54190837/helm-install-in-kuberneres-error-this-command-needs-2-arguments-release-name but it didn't help. Can you spot what I am doing wrong? Thank you.

Kamus may represent a compromise between Sealed Secrets and SOPS. It was created especially for the GitOps use case and includes an operator. It can either manage the key material itself or obtain it from the KMS of the cloud providers. Another special feature is that Kamus encrypts secrets directly for an application. They are then decrypted by the application itself or by an init container. This means that the unencrypted secret is never present on the API server and ideally also not in an environment variable with in the container.

In addition to creating Kubernetes clusters, there is also an increasing number of opportunities to use various Infrastructure-as-Code (IaC) tools, such as Terraform, with GitOps. As was already mentioned, PipeCD offers support for Terraform. Terraform's vendor, HashiCorp, now also offers an official Terraform Kubernetes operator. However, it needs access to HashiCorp's Terraform Cloud. Alternatively, there are also third-party operators that can function without Terraform Cloud, such as the one developed by Rancher. However, it is still in alpha stage.
