A simple terraform project to quickly test out K8s variations.
- terraform
- cloud account
- a bit of time
I'm not going to say give it star since you Obviously have done it before getting to this step ;)
Clone the repository.
git clone https://github.com/frozenprocess/demo-cluster.git
cd demo-cluster
Copy a template from examples folder.
cp examples/main.tf-gcpmulticluster main.tf
Open up the newly created main.tf and adjust the variables as you like.
Use the following command to install the require provider:
terraform init
Use the following command to check the resources that will be populated in your account:
terraform plan
Note: At this point resources will be generated in your cloud account.
Use the following command to create the project:
terraform apply
after a successful deployment use the demo_connection from the output to ssh into the controlplane.
You can also pull the cluster kubeconfig directly to your local machine:
./files/get-kubeconfig.sh cluster-aThe script prompts whether you want insecure mode (insecure-skip-tls-verify: true) or standard certificate validation.
By default it writes to ~/.kube/cluster-a.yaml.
You can pass a custom destination as the second argument:
./files/get-kubeconfig.sh cluster-a ~/.kube/my-cluster.yamlThen point kubectl to that file:
export KUBECONFIG=~/.kube/cluster-a.yaml
kubectl get nodesKeep in mind that cloud providers charge you based on the time that you have spent on running resources,at any point you can use terraform destroy to completely destroy the project and.
Each templates offers variables that can be changed to adjust aspects of your deployment.
You can change these values by adjusting the examples files.
