terraform-provider-etcd's Introduction

etcd provider for Terraform

Terraform provider for etcd.

Status

Unmaintained. This is no longer under active development.

TODO

Install

This project used gb, so you must have it installed.

$ git clone https://github.com/bakins/terraform-provider-etcd
$ cd terraform-provider-etcd
$ make
$ sudo make install

will install to /usr/local/bin/terraform-provider-etcd. Set PREFIX to change this:

$sudo make install PREFIX=/usr

Note: You may need to add something like the following to ~/.terraformrc if you get an error about missing the etcd provider when running terraform:

providers {
  etcd = "/usr/local/bin/terraform-provider-etcd"
}

Usage

Discovery

Simple usage:

resource "etcd_discovery" "test" {
   size = 1
}

output "etcd" {
    value = "${etcd_discovery.test.url}"
}

The resource etcd_discovery has the following optional fields:

size - cluster size. default is 3.
endpoint - discovery endpoint. default is "https://discovery.etcd.io/new"

The resulting URL is availible in the url output of the resource -- etcd_discovery.test.url in this example.

Keys

etcd_keys operates similar to consul_keys

provider "etcd" {
    endpoint = "http://oneof.my.etcd.servers.or.proxies:port"
}

resource "etcd_keys" "ami" {
    # Read the launch AMI from etcd
    key {
        name = "ami"
        path = "service/app/launch_ami"
        default = "ami-1234"
    }

    # Set the CNAME of our load balancer as a key
    key {
        name = "elb_cname"
        path = "service/app/elb_address"
        value = "${aws_elb.app.dns_name}"
    }

# Start our instance with the dynamic ami value
resource "aws_instance" "app" {
    ami = "${etcd_keys.app.var.ami}"
    ...
}
