- Terraform EKS module:
Contents
Example[edit]
0) Download code
git clone https://github.com/hashicorp/learn-terraform-provision-eks-cluster && cd learn-terraform-provision-eks-cluster
1) Execute (tf login)
- Change TFC execution mode to local in TFC web portal
- Change name in main.tf (Terraform module: vpc section) to your prefered VPC name
- Configure your AWS profile name in
main.tf, do not use default.
export TF_CLOUD_ORGANIZATION=test
terraform init #It may take several minutes terraform plan terraform apply: Terraform EKS apply output It may take around 15 min
one liner: export TF_CLOUD_ORGANIZATION=test && tf init && tf plan && tf apply
2) Update configuration
Update kubeconfig with credentials: aws eks --region $(terraform output -raw region) update-kubeconfig --name $(terraform output -raw cluster_name) Added new context arn:aws:eks:us-east-2:XXXXXXX:cluster/myeks-eks-xxxx to /Users/youruser/.kube/config
2.1) Review EKS cluster created
kubectl get nodes NAME STATUS ROLES AGE VERSION ip-10-0-1-29.us-east-2.compute.internal Ready <none> 5m31s v1.23.9-eks-ba74326 ip-10-0-1-47.us-east-2.compute.internal Ready <none> 5m21s v1.23.9-eks-ba74326 ip-10-0-2-121.us-east-2.compute.internal Ready <none> 5m13s v1.23.9-eks-ba74326
3) Review resources:
terraform show | grep -w resource | sort | uniqterraform show | grep -w resource | sort | uniq | wc -l34
4) Configure kubectl
aws eks list-clusters --output text | awk '{print $2}' aws eks update-kubeconfig --name my-eks-cluster-name
5) Review cluster status/configuration
kubectl cluster-info kubectl cluster-info dump kubectl get all -A Default EKS installation
6) Install your desired addons:
helm install
Errors[edit]
Error: Failed to read organizationError: failed to create backend alias to target "". The hostname is not in the correct format.Error: Invalid or missing required argument .../... TF_CLOUD_ORGANIZATION- Unable to parse config file ~/.aws/config
