In this is guide i will explain how to create a Kubernetes Cluster on Digitalocean using Terraform, then i will deploy the Harbor on Cluster as a internal container registry

Terraform Files

the terraform code used to create the cluster

resource "digitalocean_kubernetes_cluster" "tayeh-cluster" {
  name   = "tayeh-cluster"
  region = "fra1"
  version = "1.21.5-do.0"

  node_pool {
    name       = "worker-pool"
    size       = "s-1vcpu-2gb"
    node_count = 3
    auto_scale = true
    min_nodes  = 3
    max_nodes  = 4

after prepare the Terraform code execute this command to apply it

terraform init
export TF_VAR_do_token=<do_token>
terraform apply

now you can download the config on Digitalocean Kubernetes Cluster page, and try to connect to your cluster

[tayeh@fedora ~]$ kubectl --kubeconfig="tayeh-cluster-kubeconfig.yaml" get nodes
NAME                STATUS   ROLES    AGE   VERSION
worker-pool-uwtu0   Ready    <none>   25m   v1.21.5
worker-pool-uwtu1   Ready    <none>   25m   v1.21.5
worker-pool-uwtuz   Ready    <none>   25m   v1.21.5

deploy Harbor to Cluster

first we need to install Helm using this command

curl -fsSL -o
chmod 700 

Install ingress-nginx controller

helm upgrade --install ingress-nginx ingress-nginx \
  --repo \
  --namespace ingress-nginx --create-namespace \

Get Nginx IP

kubectl get svc -n ingress-nginx --kubeconfig=tayeh-cluster-kubeconfig.yaml

point your DNS to the EXTERNAL-IP

harbor create value file

  type: ingress
    enabled: false
harborAdminPassword: "P@ssw0rd"

then Download Chart

helm repo add harbor
helm install harbor harbor/harbor --values harbor.yml -n harbor --create-namespace --kubeconfig=tayeh-cluster-kubeconfig.yaml
kubectl patch ingress/harbor-ingress -p '{"spec": {"ingressClassName": "nginx"}}' -n harbor --kubeconfig=tayeh-cluster-kubeconfig.yaml

check containers using

[tayeh@fedora ~]$ kubectl --kubeconfig=tayeh-cluster-kubeconfig.yaml get pods -n harbor
NAME                                    READY   STATUS    RESTARTS   AGE
harbor-chartmuseum-7ddd5db67-2c7tf      1/1     Running   0          4m22s
harbor-core-6487f6cb4d-6qzz9            1/1     Running   0          4m22s
harbor-database-0                       1/1     Running   0          4m22s
harbor-jobservice-5f7c6784f4-plrz6      1/1     Running   0          4m22s
harbor-notary-server-5466b7fc4-w5s8h    1/1     Running   2          4m22s
harbor-notary-signer-77797d55f6-kx6wh   1/1     Running   2          4m22s
harbor-portal-7dcf769575-6mjkd          1/1     Running   0          4m22s
harbor-redis-0                          1/1     Running   0          4m22s
harbor-registry-7b7f7f547f-xvvmg        2/2     Running   0          4m22s
harbor-trivy-0                          1/1     Running   0          4m22s

and now you can access harbor via hostname

teraaform and value files uploaded to github
