Resource Metadata

Expose key workspace information to your users via coder_metadata resources in your template code.

Coder automatically generates the type metadata.

You can use coder_metadata to show

• Compute resources
• IP addresses
• Secrets
• Important file paths

and any other Terraform resource attribute.

Example

Expose the disk size, deployment name, and persistent directory in a Kubernetes template with:

resource "kubernetes_persistent_volume_claim" "root" {
    ...
}

resource "kubernetes_deployment" "coder" {
  # My deployment is ephemeral
  count = data.coder_workspace.me.start_count
  ...
}

resource "coder_metadata" "pvc" {
  resource_id = kubernetes_persistent_volume_claim.root.id
  item {
    key = "size"
    value = kubernetes_persistent_volume_claim.root.spec[0].resources[0].requests.storage
  }
  item {
    key = "dir"
    value = "/home/coder"
  }
}

resource "coder_metadata" "deployment" {
  count = data.coder_workspace.me.start_count
  resource_id = kubernetes_deployment.coder[0].id
  item {
    key = "name"
    value = kubernetes_deployment.coder[0].metadata[0].name
  }
}
