Hello,

The API allows you to manage your Docker registry, but in order to push a Docker image to your Registry, you could follow these steps here:

• Install doctl and authenticate it with an API token

• Use the registry login command to authenticate Docker with your registry:

doctl registry login

Use the docker tag command to tag your image with the fully qualified destination path:

docker tag <my-image> registry.digitalocean.com/<my-registry>/<my-image>

Use the docker push command to upload your image:

docker push registry.digitalocean.com/<my-registry>/<my-image>

If you push a new image using an existing tag, the tag gets updated but the old image is still accessible by its digest and takes up space in your registry.

To reduce your storage usage, you can delete the untagged images and then run garbage collection.

Best,
Bobby
