Several container images inside one project

Hello

I’m using self-hosted GitLab CE.
As I can see here https://gitlab.gravitel.ru/help/user/packages/container_registry/index GitLab CE allows to push several containers with different names inside a project.
If I build and push a container like this
docker push $CI_REGISTRY/$CI_PROJECT_NAMESPACE/$CI_PROJECT_NAME:latest
I can see in https://gitlab.{myhost}/{group}/{project}/container_registry list of available containers.
But if I build several containers like this
docker push $CI_REGISTRY/$CI_PROJECT_NAMESPACE/$CI_PROJECT_NAME/${container}:$CI_COMMIT_TAG
I couldn’t see anything on Package / Container Registry page.
Does anybody have any idea what going wrong?
