How to Integrate with a DigitalOcean Container Registry

Validated on 26 Sep 2022 • Last edited on 10 Apr 2023

DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains, integrate natively with DigitalOcean Load Balancers and volumes, and can be managed programmatically using the API and command line. For critical workloads, add the high-availability control plane to increase uptime with 99.95% SLA.

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

To add a container registry via the command-line, follow these steps:

Install doctl, the DigitalOcean command-line tool.
Create a personal access token, and save it for use with doctl.
Use the token to grant doctl access to your DigitalOcean account.
```
              doctl auth init
            
```
Finally, add a container registry with doctl kubernetes cluster registry add. The basic usage looks like this, but you'll want to read the usage docs for more details:
```
              doctl kubernetes cluster registry add <cluster-id|cluster-name> <cluster-id|cluster-name> [flags]
            
```

How to add a container registry using the DigitalOcean API

To add a container registry using the DigitalOcean API, follow these steps:

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

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

cURL

To add a container registry with cURL, call:


                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

Go developers can use Godo, the official DigitalOcean V2 API client for Go. To add a container registry with Godo, use the following code:


                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"}})
}
