GCP

Requirements

Terraform needs to be locally installed. A GCP account is needed.

Instructions for GCP

  1. Make sure you're authenticated to use GCP. The easiest way is through the gcloud CLI:

    gcloud auth application-default login

    More info as well as alternative options can be found in the Terraform provider docs

  2. Navigate to the terraform/gcloud folder

    $ cd terraform/gcloud

  3. Initialize terraform

    $ terraform init

  4. Create a terraform.tfvars file inside the terraform/gcloud folder It needs to contain the following as a minimum:

    gcloud_project    = "myGCPProject" # GCP Project you want to use
gcloud_zone       = "europe-west1-b" # zone where you want to provision the resources. Check out https://cloud.google.com/compute/docs/regions-zones#available for available zones

    Check out variables.tf for a complete list of variables

  5. Verify the configuration by running terraform plan

    $ terraform plan

  6. Apply the configuration

    $ terraform apply

Send OpenTelemetry Traces to Dynatrace

It is possible to leverage the Ansible OpenTelemetry callback plugin to send Traces to the Dynatraces API.

The following variable need to be set to enable it:

otel_export_enable = true

Note: The traces will be sent to the dt_tenant/api/v2/otlp endpoint Note: The api token specified in the dt_api_token variable needs to have the additional openTelemetryTrace.ingest scope

Custom domain support

This terraform script supports the use of custom domains via Cloud DNS.

  1. Ensure your service account can create DNS records in the target Cloud DNS managed zone.

  2. Add the following values to the terraform.tfvars file:

    gcloud_project    = "myGCPProject" # GCP Project you want to use
gcloud_zone       = "europe-west1-b" # zone where you want to provision the resources. Check out https://cloud.google.com/compute/docs/regions-zones#available for available zones
custom_domain     = "acebox.example.com" # Set to override default domain (ip_address.xip.io)
managed_zone_name = "example.com" # Name of Cloud DNS managed zone
