The text provides a detailed guide on creating a GitHub Action that exposes an SSH server, allowing users to debug GitHub workflow containers. It explains the process of setting up a simple GitHub Action using a composite action, which runs executable commands within a shell. The key steps include setting up SSH configurations, fetching public SSH keys from GitHub's API, generating server keys, starting an SSH server, and using Cloudflare's Tunnel to expose the server online. The guide highlights the use of environment variables and tools like `sshd`, `cloudflared`, and `tmux` to manage and monitor the SSH session. It emphasizes the convenience of using Cloudflare's guest mode, which eliminates the need for an API key, and suggests that a native GitHub SSH feature would simplify debugging efforts further.
