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

Result:

REPOSITORY                                  TAG     IMAGE ID      CREATED       SIZE
cr.il.nebius.cloud/crpd50616s9a2t7gr8mi/ubuntu  hello   50ff4b0e5783  23 hours ago  86.7MB
ubuntu                                      latest  1d9c17228a9e  2 weeks ago   86.7MB

(optional) Assign a URL in the format cr.il.nebius.cloud/<registry ID>/<Docker image name>:<tag> to the Docker image:
```
docker tag ubuntu \
cr.il.nebius.cloud/crpd50616s9a2t7gr8mi/ubuntu:hello
```
Note

You can only push Docker images with a URL in the format cr.il.nebius.cloud/<registry ID>/<Docker image name>:<tag> to Container Registry.

Push the required Docker image to the registry:

docker push cr.il.nebius.cloud/crpd50616s9a2t7gr8mi/ubuntu:hello

Make sure the image uploaded to the registry by getting a list of docker images in the registry.
