terraform-provider-elasticsearch

This is a terraform provider that lets you provision Elasticsearch and Opensearch resources, compatible with v6 and v7 of Elasticsearch and v1 of Opensearch. Based off of an original PR to Terraform.

Using the Provider

Terraform 0.13 and above

This package is published on the official Terraform registry. Note, we currently test against the 1.x branch of Terraform - this should continue to work with >= 0.13 versions, however, compatibility is not tested in the >= 2.x version of this provider.

Terraform 0.12 or manual installation

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.

Terraform 0.11

With version 2.x of this provider, it uses version 2.x of the Terraform Plugin SDK which only supports Terraform 0.12 and higher. Please see the 1.x releases of this provider for Terraform 0.11 support.

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
}

For use with AWS Opensearch domains

Please see the documentation for details.

Development

Requirements

• Golang >= 1.13

go build -o /path/to/binary/terraform-provider-elasticsearch

Running tests locally

Start an instance of ElasticSearch locally with the following:

./script/install-tools
export OSS_IMAGE="opensearchproject/opensearch:1.2.0"
export ES_OPENDISTRO_IMAGE="opensearchproject/opensearch:1.2.0"
export ES_COMMAND=""
export ES_KIBANA_IMAGE=""
export OPENSEARCH_PREFIX="plugins.security"
export OSS_ENV_VAR="plugins.security.disabled=true"
export XPACK_IMAGE="docker.elastic.co/elasticsearch/elasticsearch:7.10.1"
docker-compose up -d
docker-compose ps -a

When running tests, ensure that your test/debug profile has environmental variables as below:

• ELASTICSEARCH_URL=http://localhost:9200_
• TF_ACC=1

Debugging this provider

Build the executable, and start in debug mode:

$ go build
$ ./terraform-provider-elasticsearch -debuggable # or start in debug mode in your IDE
{"@level":"debug","@message":"plugin address","@timestamp":"2022-05-17T10:10:04.331668+01:00","address":"/var/folders/32/3mbbgs9x0r5bf991ltrl3p280000gs/T/plugin1346340234","network":"unix"}
Provider started, to attach Terraform set the TF_REATTACH_PROVIDERS env var:

        TF_REATTACH_PROVIDERS='{"registry.terraform.io/phillbaker/elasticsearch":{"Protocol":"grpc","ProtocolVersion":5,"Pid":79075,"Test":true,"Addr":{"Network":"unix","String":"/var/folders/32/3mbbgs9x0r5bf991ltrl3p280000gs/T/plugin1346340234"}}}'

In another terminal, you can test your terraform code:

$ cd <my-project/terraform>
$ export TF_REATTACH_PROVIDERS=<env var above>
$ terraform apply

The local provider will be used instead, and you should see debug information printed to the terminal.
