Linode_LKE_POC

Linode LKE POC

A small POC for setting up a load balanced LKE cluster with an nginx hello world deployment.

Using the project

This project assumes you have a Linode account already setup, and you have generated an API token.

Terraform ./terraform

Before running any terraform commands you will need to export your linode api token:

export TF_VAR_linode_token="your_linode_api_token"

Run:

terraform init 
terraform apply

Helm ./helm

After the terraform has sucessfully run, login to your linode account and navigate to kubernetes clusters at https://cloud.linode.com/kubernetes/clusters and use Download Kubeconfig to get access to the cluster for performing the helm install.

To install the nginx deployment, navigate to ./helm and run install.sh.

For simplicity everything is installed in the default namespace.

Verification

After the helm install completes run kubectl get po and make sure you see at least 1 running nginx pod.

Run kubectl get svc and you should see a service called hello-world.

Wait for this service to have an EXTERNAL-IP.

After that you should be able to visit http://<EXTERNAL-IP> and see Hello World from Nginx!.

Tear down

To uninstall the nginx deployment, navigate to ./helm and run uninstall.sh.

To teardown the infra, navigate to ./terraform and run terraform destroy.
