terraform-provider-elasticsearch

terraform-provider-elasticsearch

This is a terraform provider that lets you provision elasticsearch resources, compatible with v5, v6 and v7 of elasticsearch. Based off of an original PR to Terraform.

Installation

This package is published on the official Terraform registry.

Or download a binary, and put it in a good spot on your system. Then update your ~/.terraformrc to refer to the binary:

providers {
  elasticsearch = "/path/to/terraform-provider-elasticsearch"
}

See the docs for more on manual installation.

Usage

provider "elasticsearch" {
    url = "https://search-foo-bar-pqrhr4w3u4dzervg41frow4mmy.us-east-1.es.amazonaws.com" # Don't include port at the end for aws
    aws_access_key = ""
    aws_secret_key = ""
    aws_token = "" # if necessary
    insecure = true # to bypass certificate check
    cacert_file = "/path/to/ca.crt" # when connecting to elastic with self-signed certificate
    sign_aws_requests = true # only needs to be true if your domain access policy includes IAM users or roles
}
