Terraform provider for managing Apache Pulsar entities

terraform-provider-pulsar

A Terraform provider for managing Apache Pulsar Entities.

Contents

• Requirements
• Installation
• Resources
  • pulsar_tenant
  • pulsar_cluster
  • pulsar_namespace
  • pulsar_topic

Requirements

• Terraform 0.10+
• Go 1.13 (to build the provider plugin)

Installation

• Clone this repository and cd into the directory
• Run make build, it will out a file named terraform-provider-pulsar
• Copy this terraform-provider-pulsar bin file to your terraform plugin directory
• Typically this plugin directory is ~/.terraform.d/plugins/
• On Linux based 64-bit devices, this directory can be ~/.terraform.d/plugins/linux_amd64

Testing the Apache Pulsar Terraform Provider

• change directory to the project </path/to/provider/terraform-provider-pulsar>

• Make sure you have the required tools installed. Run make tools

• 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.

  }
}

resource "pulsar_topic" "sample-topic-2" {

Importing existing resources

All resources could be imported using the standard terraform way.

Example

terraform import pulsar_cluster.standalone standalone
