Terraform

Terraform is a Cloud configuration tool from Hashicorp found at terraform.io, we maintain a Provider for Terraform called terraform-provider-jetstream that can maintain JetStream using Terraform.

Setup

Our provider is not hosted by Hashicorp so installation is a bit more complex than typical. Browse to the Release Page and download the release for your platform and extract it into your Terraform plugins directory.

$ unzip -l terraform-provider-jetstream_0.0.2_darwin_amd64.zip

}

And start using it, here's an example that create the ORDERS example. Review the Project README for full details.

resource "jetstream_stream" "ORDERS" {
name = "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"
