Getting Docker private registry URL

I have been trying to deploy [to a Kubernetes cluster] a Docker image that is present in my private Docker registry. So, my private registry in Docker looks like this:

summer/my-app:version1.1

In order to deploy the app to a Kubernetes cluster, I need to specify the image name in my-app-deployment.yml file. This image name however requires a complete path to the registry. Unlike from official Docker images which uses the format like this: registry.hub.docker.com/<user>/<image>, it did not work in my case and yielded an error ImagePullBackOff during deployment.

Is there a different format to this, when deploying from a private Docker registry?

By default, when you don't specify which registry to query, then it would use docker.io, see https://kubernetes.io/docs/concepts/containers/_print/#image-names

You may however configure default registries. https://manpages.ubuntu.com/manpages/hirsute/man5/containers-registries.conf.5.html

Though I'm not sure docker itself takes this under consideration. It really depends on your runtime. While in a Kubernetes cluster context, those configurations are probably managed by something else (Kops, Kubespray, ...).
