Pushing a Docker image to a registry

These instructions describe how to push a local Docker image to a registry.

Note

To push an image, you need to authenticate in the registry.

CLI

View the list of available Docker images:

docker image list
REPOSITORY                              TAG                 IMAGE ID            CREATED             SIZE
cr.yandex/crpd50616s9a2t7gr8mi/ubuntu   hello               50ff4b0e5783        23 hours ago        86.7MB
ubuntu                                  latest              1d9c17228a9e        2 weeks ago         86.7MB

(option) Assign a tag like cr.yandex/<registry ID>/<Docker image name>:<tag> to the Docker image:
```
docker tag ubuntu \
cr.yandex/crpd50616s9a2t7gr8mi/ubuntu:example
```
Note

You can only push to Container Registry Docker images tagged with cr.yandex/<registry ID>/<Docker image name>:<tag>.

Push the required Docker image to the registry:

docker push cr.yandex/crpd50616s9a2t7gr8mi/ubuntu:hello

Make sure the image has been added to the registry. To do this, get a list of Docker images in the registry.
