leverage Terraform Cloud to manage our state files remotely Loging into Terraform Cloud and create a new organization. For our purposes we can use the free tier.The main reason for using Terraform Cloud is that we can store our state files in a secure way. However, you can also use a local state file if you prefer to do so. Connect your VCS provider to Terraform Cloud, in my case Github. Select this repository and create a new workspace. Now you can start to configure your workspace.
In the VCS settings set the directory to src/infra.
Create a commit and push the changes to your repository to trigger a plan in Terraform Cloud.
Create a new file terraform.tfvars and add the following variables
Change working directory to src/infra and initialize terraform.
terraform initIf everything looks good you can apply the changes
terraform apply -auto-approvePopulate the Cluster
First we need to set up the kubectl context to point to our new cluster.
terraform output kubeconfig > ~/.kube/configChange working directory to src/cluster and initialize terraform.
terraform initIf everything looks good you can apply the changes
terraform apply -auto-approveThat’s it! You have now a fully functional Kubernetes cluster running the services we will see in more detail in the next sections.
