|

3. Configure your AWS credentials using one of the [options supported by the AWS
|
||||
SDK](http://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/credentials.html). Usually, the easiest option is to
|
||||
set the `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_DEFAULT_REGION` environment variables.
|
||||
4. Update the `variables` section of the `consul.json` Packer template to configure the AWS region, Consul version, and datadog api key you would like to use. Feel free to reference this article to find your [datadog API key](https://docs.datadoghq.com/account_management/api-app-keys/#api-keys).

4. Update the `variables` section of the `consul.json` Packer template to configure the AWS region and datadog api key you would like to use. Feel free to reference this article to find your [datadog API key](https://docs.datadoghq.com/account_management/api-app-keys/#api-keys).
|
||||
5. For additional customization you can add [tags](https://docs.datadoghq.com/getting_started/tagging/assigning_tags/?tab=noncontainerizedenvironments) within the `scripts/datadog.yaml` file. One example of a tag could be `"consul_version" : "consulent_175"`. These tags are searchable through the datadog dashboard. Another form of customization is changing the datacenter tag within `scripts/telemetry.json`, however it is defaulted to `us-east-1`.
|
||||
6. Run `packer build consul.json`.

4. AWS Variables are set off of environment variables. Make sure to export nessecary variables [shown here](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#environment-variables).

5. Run `terraform plan -var-file=vars.tfvars`, and then `terraform apply -var-file=vars.tfvars` when ready.
|

6. Upon completion k6 should run and push metrics to desired Datadog dashboard.
