Creating your Kubernetes cluster

Prerequisites

• terraform
• doctl
• kubectl

The terraform directory contains an example on how to create a Kubernetes cluster on Digitalocean.

# Move to terraform dir
$ cd terraform

# Initialize terraform
$ terraform init

# See what's going to happen
$ terraform plan

# If all looks good, apply changes to create your cluster
$ terraform apply

Once the stack is created you can obtain your ~/.kube config file by using the doctl cli.

# Initialize authentication
$ doctl auth init

# List available clusters
$ doctl kubernetes cluster list

# Save your connection iformation to ~/.kube/config
$ doctl kubernetes cluster kubeconfig save <CLUSTER_ID>

# Check that it works
$ kubectl get nodes

Using helmsman to deploy multiple helm charts

Prerequisites

• helm
• helmsman
• helm-diff

The helmsman directory contains an example on how to deploy the helm charts using helmsman.

# Install shared services (e.g. Kube Prometheus Stack, Cert-manager, External-DNS, Ingress Nginx)
helmsman -f shared-services.yaml --show-diff --apply

# Install the charts defined in ethereum.yaml
# Note: You should check the file before applying it and adjust values to your requirements
helmsman -f ethereum.yaml --show-diff --apply

The following is an example on how to destroy everything created by a given stack:

# Delete everything that was applied by the "ethereum.yaml" stack
helmsman --no-banner -f ethereum.yaml --destroy
# Delete any PVC that was created
kubectl -n ethereum delete pvc --all

Cleanup

Destroy the whole kubernetes cluster

# Destroy all terraform resources
cd terraform && terraform destroy
