terraform-kubernetes-argocd-application

This module deploys an ArgoCD application custom resource. It utilizes the kubectl provider instead of the official Kubernetes provider to mitigate common problems with custom resources in Terraform, such as:

• Required API access during planning time, requiring multiple terraform states in order to deploy an application to Kubernetes.
• Sensitive values are displayed in logs, ref.

Example Implementations

Basic

You can make use of the built-in templatefile() function to easily add secret values to the platform_services_values if secret configuration is required.

provider "kubectl" {
  # provider configuration ...
}

module "my_app" {
  source = "catalystcommunity/argocd-application/kubernetes"

  name            = "my-app"
  source_chart    = "my-app"
  source_repo_url = "https://example.com/repository"
  helm_values     = templatefile("./helm-values/my-application-values.yaml", {
    "exampleSecretInput" : var.example_secret
  })
}
