Terraform Provider

Terraform Provider

Source on GitHub: terraform-provider-HDB-HeliosDB-Proxy

The Terraform provider wraps the Kubernetes operator: each resource calls controller-runtime/client to apply the corresponding CRD against the cluster. Five resources mirror the five CRDs one-for-one.

provider "heliosproxy" {
  namespace = "data"
}

resource "heliosproxy_pool_profile" "default" {
  name          = "default-pool"
  mode          = "transaction"
  max_pool_size = 200
}

resource "heliosproxy_instance" "analytics" {
  name             = "analytics"
  replicas         = 2
  image            = "ghcr.io/dimensigon/hdb-heliosdb-proxy:0.4.0"
  pool_profile_ref = heliosproxy_pool_profile.default.name
  nodes = [
    { host = "pg-primary.db.svc", port = 5432, role = "primary", weight = 100 },
    { host = "pg-standby.db.svc", port = 5432, role = "standby", weight = 100 },
  ]
}

Schema-import pattern

The schema doesn’t drift from the operator because it imports the operator’s Go types directly via a local replace directive. Adding a field to the operator’s CRD makes it available in the provider on the next make tidy && go build.
