You can host the chart yourself. I have extended the capabilities of the offline files_repo to additionally act as a helm repo (my files_repo is a simple server hosted via nginx). Here's how I added kubelet-csr-approver support in offline mode:

Step 1: Enable installation of helm:

helm_download_url: "{{ files_repo }}/helm-{{ helm_version }}-linux-{{ image_arch }}.tar.gz"

Step 2: Get the release and index.yaml from kubelet-csr-approver repo and host it.

Step 3: Define necessary variables:

# helm server runs under /helm
helm_repo: "{{ files_repo }}/helm"
kubelet_csr_approver_repository_url: "{{ helm_repo }}"

Step 4: Ensure the helm server is hosted with TLS and make sure your cluster node-1 trusts the certificate chain.

Install the cluster as usual. You should have the chart installed without a problem.
