Terraform

Terraform is a Cloud configuration tool from Hashicorp. We maintain a Provider for Terraform called terraform-provider-jetstream that can maintain JetStream using Terraform.

Find it in the Terraform registry.

Setup

In your project you can configure the Provider like this:

provider "jetstream" {
  servers = "connect.ngs.global"
  credentials = "ngs_jetstream_admin.creds"
}

Sample code below that creates the ORDERS example. Review the Project README for full details.

resource "jetstream_stream" "ORDERS" {
  name     = "ORDERS"
  subjects = ["ORDERS.*"]
  storage  = "file"
  max_age  = 60 * 60 * 24 * 365
}

resource "jetstream_consumer" "ORDERS_NEW" {
  stream_id      = jetstream_stream.ORDERS.id
  durable_name   = "NEW"
  deliver_all    = true
  filter_subject = "ORDERS.received"
  sample_freq    = 100
}

resource "jetstream_consumer" "ORDERS_DISPATCH" {
  stream_id      = jetstream_stream.ORDERS.id
  durable_name   = "DISPATCH"
  deliver_all    = true
  filter_subject = "ORDERS.processed"
  sample_freq    = 100
}

resource "jetstream_consumer" "ORDERS_MONITOR" {
  stream_id        = jetstream_stream.ORDERS.id
  durable_name     = "MONITOR"
  deliver_last     = true
  ack_policy       = "none"
  delivery_subject = "monitor.ORDERS"
}

output "ORDERS_SUBJECTS" {
  value = jetstream_stream.ORDERS.subjects
}
