ko
Build and deploy Go applications on Kubernetes
... it a powerful tool for Kubernetes applications. ko depends on the authentication configured in your Docker config. If you can push an image with docker push, you are already authenticated for ko. Since ko doesn't require docker, ko login also provides a surface for logging in to a container image registry with a username and password, similar to docker login. Additionally, if auth is not configured in the Docker config, ko includes built-in support for authenticating container registries.
