   available on http://argocd.local.

 2. **GitOps using your own repository**: installs ArgoCD, no Cilium LB config, no Ingress and the Kubernetes resources in
   the repository you specify in `argocd_app_of_apps_source`. Credentials for a private repository can be configured
   and installed with OpenTofu using `install_argocd_app_of_apps_git_repo_secret` and the related variables:
   * install_cilium_lb_config = false
-   * argocd_domain = "yourpublicdomain.com"
-   * argocd_server_insecure = true
-   * argocd_ingress_enabled = false
+   * argocd_helm_values: add your Helm values and override defaults, for instance keep server insecure and switch off ingress
