Terraform

The topic explains how to use Terraform to install the Traceable platform agent in a Kubernetes environment. Make sure that Terraform is already installed before proceeding with installing Traceable Platform agent. For more information on installing Terraform, see Download Terraform.

Before you begin

Keep the Traceable agent token handy. Navigate to Traceable's platform and navigate to Settings () > Account > Access Tokens > Agent Token. Copy and save the token. It would be required in the Traceable agent installation process.

Download

Enter the following command to download the latest Terraform tarball:

curl -O https://downloads.traceable.ai/install/traceable-agent/terraform/kubernetes/latest/traceable-agent-tf-k8s.tar.gz

Installation

Complete the following steps to install traceable-agent. Make sure

1. Create traceableai namespace by entering the following command:

   kubectl create namespace traceableai

2. Untar the Terraform archive that you downloaded earlier. Enter the following command:

   tar xvzf traceable-agent-tf-k8s.tar.gz

3. Change the directory.

   cd traceable-agent-tf-k8s/

4. Initialize the module by entering the following command:

   terraform init

5. Review the setup that will be installed by entering the following command. Add the agent token that you downloaded earlier.

   terraform plan -var='token='

6. Apply the module by entering the following command:

   terraform apply -var='token='

   Terraform creates a terrafrom.tfstate file. The file stores the current state of the infrastructure. It is recommended to keep track of this file.

Load balance Platform agent

In a deployment where you have deployed more than one Traceable Platform agent, and you expect high span load, you load balance the spans among the Platform agents. Load balancing is available in Platform agent 1.26.0 and later and only applies to the Go agent. In Helm chart, add the following value:

service_type:Headless

Verify the installation

Enter the following command to verify a successful installation of traceable-agent:

kubectl get pods -n traceableai

For example,

NAME                                     READY   STATUS    RESTARTS   AGE
traceable-agent-d8ff7cd79-qn2wb          1/1     Running   0          34m
