Working with the Lightning CLI to Manage Lightning Studios

Lightning Studios are persistent cloud development environments that retain files and configurations while allowing users to move between CPU and GPU machines without managing infrastructure, networking, or cloud accounts. Although the web interface supports these tasks, the Lightning CLI offers a terminal-centered alternative for developers using external IDEs and SSH, enabling them to list, start, stop, switch, and connect to Studios from one workflow. After installing the Lightning SDK and authenticating through a browser or environment variables, users can manage teamspaces, generate SSH configurations for remote IDE access, transfer files through `lit://` paths even when a Studio is stopped, and launch reproducible training jobs directly from Docker images. The post also recommends checking CLI configuration when troubleshooting and protecting API credentials through restrictive file permissions, key rotation, or secret-management tools. It concludes that the web UI remains useful for browsing and occasional tasks, while the CLI can reduce repetitive compute-management steps for terminal-focused users.
