# FastAPI CLI

**FastAPI CLI** is a command line program `fastapi` that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install fastapi`), it includes a package called `fastapi-cli`, this package provides the `fastapi` command in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

func getPodsNameInDefaultNamespace(ctx cli.Context, toComplete string) ([]string, error) {
	client, err := ctx.CLIClient()
	if err != nil {
		return nil, err
	}
	ns := ctx.NamespaceOrDefault(ctx.Namespace())
