Hello,

In order to get started with the DigitalOcean Docker Registry, you can follow the steps here.

Prerequisites

• Make sure that you have Docker installed:

https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04

• Install the doctl command-line tool:

https://www.digitalocean.com/docs/apis-clis/doctl/how-to/install/

First create a Docker Registry:

• Visit the registry page under Images.
• Enter a name for your registry. This name must be globally unique.
• You will be advised if you need to enable a Spaces subscription first, which you can do by visiting the Spaces area of the control panel.

You could also create a registry via your command line with the following command:

doctl registry create your-registry-name

With that, your registry will be ready and you will be able to push new Docker images.

Push to Your DigitalOcean Registry

In order to push an image, you need to first login to your DigitalOcean Docker Registry:

doctl registry login

After that tag your image with the fully qualified destination path:

docker tag your-image-name registry.digitalocean.com/your-registry-name/your-image-name

Finally by using the docker push command to upload your image:

docker push registry.digitalocean.com/your-registry-name/your-image-name
