// Controller is an interface to manage sandboxes at runtime. // Controller is an interface to manage sandboxes at runtime.
// When running the traditional containerd shim, the workflow looks as follows: // When running in sandbox mode, shim expected to implement `SandboxService`.
// For each new task we're about to run: // Shim lifetimes are now managed manually via sandbox API by the containerd's client.
// 1. Invoke `shim_binary --start` to obtain `TaskService` address (printed in stdout)
// 2. Call TaskService.RunContainer(id=1)
// 3. Exec `shim_binary --delete` to stop shim
// 4. Exec `shim_binary --start` again to obtain another `TaskService` address
// 5. TaskService.RunContainer(id=2)
// 6. Exec `shim_binary --delete` to stop shim
//
// When running in sandbox mode, shim must implement `SandboxService`.
// In sandbox mode shim lifetimes are managed manually via sandbox API.
// 1. Client calls `client.SandboxController.Start()` to launch new shim and create sandbox process
// 2. Run containers with `shim.TaskService.RunContainer(id=1)` and another one `shim.TaskService.RunContainer(id=2)`
// 3. ... usual container lifecycle calls to `shim.TaskService`
// 4. Client calls shim to stop the sandbox with `client.SandboxService.Shutdown()`
// 5. Shim implementation will perform cleanup similar to regular task service (e.g. shutdown, clean, and `shim_binary --delete`)
