Terraform is an Infrastructure as Code tool (IaC) which manages resources with configuration files rather than through GUIs or custom scripts. It allows you to build, change, and manage your resources in a safe, consistent, and repeatable way by defining the infrastructure in a declarative way. We will be using Terraform along with Terraform cloud to deploy all of the necessary resources needed to create a DigitalOcean kubernetes cluster.

We’ll be continuing our ingress-nginx journey by installing and setting up cert-manager via helm to be able to create TLS certificates to associate with backend service hosts which will create a secure TLS connection. We will use cert-manager to set up a DNS-01 challenge using the DigitalOcean Provider.

Today we’ll be installing and configuring the kubernetes-supported ingress-nginx controller via helm into a digitalocean kubernetes cluster (DOKS). Which will use nginx as a reverse proxy and load balancer.
