How to Integrate with a DigitalOcean Container Registry

DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service. Deploy Kubernetes clusters with a fully managed control plane, high availability, autoscaling, and native integration with DigitalOcean Load Balancers and volumes. You can add node pools using shared and dedicated CPUs, and NVIDIA H100 GPUs in a single GPU or 8 GPU configuration. DOKS clusters are compatible with standard Kubernetes toolchains and the DigitalOcean API and CLI.

On DigitalOcean, you can integrate your Kubernetes cluster with a container registry via the control panel. This process requires you to have an existing container registry. If you don’t have an existing registry, first create one.

To integrate a cluster, go to the control panel and click the Kubernetes cluster you want to integrate. Then, click the Settings tab, scroll down to the DigitalOcean Container Registry Integration section, and click Edit to the right.

Check your container registry and click Save to confirm your change.

Add a Container Registry to a Cluster Using Automation

How to Add a Container Registry Using the DigitalOcean CLI

  1. Install doctl, the DigitalOcean command-line tool.

  2. Create a personal access token and save it for use with doctl.

  3. Use the token to grant doctl access to your DigitalOcean account.

              doctl auth init

  4. Finally, run doctl kubernetes cluster registry add. Basic usage looks like this, but you can read the usage docs for more details:

                doctl kubernetes cluster registry add <cluster-id|cluster-name> <cluster-id|cluster-name> [flags]

    The following example adds container registry support to a cluster named example-cluster:

                  doctl kubernetes cluster registry add example-cluster
How to Add a Container Registry Using the DigitalOcean API

  1. Create a personal access token and save it for use with the API.

  2. Send a POST request to https://api.digitalocean.com/v2/kubernetes/registry

    cURL

    Using cURL:

                    curl -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"cluster_uuids": ["bd5f5959-5e1e-4205-a714-a914373942af", "50c2f44c-011d-493e-aee5-361a4a0d1844"]}' \
  "https://api.digitalocean.com/v2/kubernetes/registry"

    Go

    Using Godo, the official DigitalOcean V2 API client for Go: 

                    import (
    "context"
    "os"

    "github.com/digitalocean/godo"
)

func main() {
    token := os.Getenv("DIGITALOCEAN_TOKEN")

    client := godo.NewFromToken(token)
    ctx := context.TODO()

    _, err := client.Kubernetes.AddRegistry(ctx, &godo.KubernetesClusterRegistryRequest{ClusterUUIDs: []string{"bd5f5959-5e1e-4205-a714-a914373942af"}})
}

    Python

                    import os
from pydo import Client

client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))

req = {
  "cluster_uuids": [
    "bd5f5959-5e1e-4205-a714-a914373942af",
    "50c2f44c-011d-493e-aee5-361a4a0d1844"
  ]
}

resp = client.kubernetes.add_registry(body=req)
