Recently in Angular CLI v8.3.0 ng deploy command is introduced.

ng deploy executes the deploy CLI builder associated with your project. A number of third-party builders implement deployment capabilities to different platforms. You can add any of them to your project by running ng add [package name] .

When you add a package with deployment capability, it’ll automatically update your workspace configuration ( angular.json file) with a deploy section for the selected project. You can then use the ng deploy command to deploy that project.
