Terraform

These resources should be built with Terraform: https://terraform.io

Manage Kubernetes with Terraform. This effectivelly replaces all kubectl and helm commands with a single terraform apply.

Install Terraform

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
sudo yum -y install terraform

curl -sSfL "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip ./awscliv2.zip
sudo ./aws/install
rm -f awscliv2.zip

Kubernetes Provider

The Kubernetes provider is used to interact with the resources supported by Kubernetes. The provider needs to be configured with the proper credentials before it can be used.

Kubectl Provider

This provider is likely the best way of managing Kubernetes resources in Terraform, by allowing you to use yaml.

Helm Provider

The Helm provider is used to deploy software packages in Kubernetes.

Deployment

Configure AWS S3 and DynamoDB for Remote State Files

See configuration instructions here:

https://www.lisenet.com/2020/terraform-with-aws-s3-and-dynamodb-for-remote-state-files/

See required IAM account permissions terraform-aws-iam-permissions.json.

Apply Terraform Configuration

Requires Terraform v1.0 or above.

Terraform has not been configured to create certain namespaces, therefore run the following:

kubectl create ns kubecost
kubectl create ns logging
kubectl create ns speedtest

Change to your project directory and run the following:

terraform init -upgrade
terraform apply
