Push to a gitlab container registry

[bahugo]

Hello everyone,

I'd like to publish a singularity image to a gitlab container registry.

I've found examples using docker, I've found this https://singularityhub.github.io/sregistry-cli/client-gitlab which exposes how to pull from a gitlab container but nothing related to publishing to a gitlab container.

Does anyone knows how it could be done?

Thank you!
