Terraform Provider for Pulsar

A Terraform provider for managing Apache Pulsar Entities.

Prerequisites

Terraform 0.12.0 or later
Go 1.16 or later (to build the provider plugin)

Installation

From terraform registry

This provider has been published in the Terraform Registry:

terraform {
  required_providers {
    pulsar = {
      version = "0.1.0"
      source = "registry.terraform.io/streamnative/pulsar"
    }
  }
}

From source code
- Clone this repository and cd into the directory
- Run make build, it will generate a binary file named terraform-provider-pulsar
- Copy this terraform-provider-pulsar binary file to your terraform plugin directory based on your OS:

Operating System	User plugins directory
Windows(amd64)	%APPDATA%\terraform.d\plugins\registry.terraform.io\streamnative\pulsar\0.1.0\windows_amd64\
Linux(amd64)	~/.terraform.d/plugins/registry.terraform.io/streamnative/pulsar/0.1.0/linux_amd64/
MacOS(amd64)	~/.terraform.d/plugins/registry.terraform.io/streamnative/pulsar/0.1.0/darwin_amd64/

Run make build-dev, it will build the binary and copy it to the plugin directory automatically.

Importing existing resources

All resources could be imported using the standard terraform way.

Example

terraform import pulsar_cluster.standalone standalone

Testing the Provider

Change directory to the project </path/to/provider/terraform-provider-pulsar>
In order to test the provider, you can run make test
In order to run the full suite of Acceptance tests, run make testacc

Note: Acceptance tests create real resources, and often cost money to run.
