Using Terraform to push a distributed application

Now that you have EKS deployed, we will use a separate set of Terraform IaC to deploy the distributed application itself.

Components

• Kubernetes deployments – Three deployments in separate namespaces and with separate node taints. This will force pods to deploy to either the parent region, the Local Zone, or the Wavelength Zone, as appropriate.
• Kubernetes services – A simple NodePort service will allow traffic from each node’s public IP address into those locations. This will allow you to test accessing containers in EKS via three different paths into AWS.

Deploying the distributed application

In this section, you will initialize and deploy the Terraform IaC in the distributed-application/kubernetes-config directory of the repository you downloaded.

NOTE:

You must replace <your_edge_city> with the same value you used in the previous section when you deployed the EKS cluster.
