HOW TO USE IT
When you need to preserve a sandbox’s disk, run `railway sandbox checkpoint create <name>` to capture the active sandbox, or add `--id <ID>` to select one. Then run `railway sandbox create --checkpoint <name>` to boot a fresh sandbox from that checkpoint.
railway sandbox checkpoint create <name>railway sandbox checkpoint create <name> --id <ID>railway sandbox create --checkpoint <name>WHY THIS HELPS
When working with a Railway sandbox, save its disk state and start a fresh sandbox from that saved state.
REQUIREMENTS AND LIMITATIONS
- Version: v5.12.0
- <name> (required): Checkpoint name; usable with `sandbox create --checkpoint`.
- --id <ID>: Select source sandbox ID; defaults to the active sandbox.
- --checkpoint <name>: Create from a named checkpoint; conflicts with `--template`.
- Prerequisite: The CLI documents that the `PROJECT_SANDBOXES` feature must be enabled.
- Checkpoint creation is synchronous and the checkpoint is ready when the command returns.
- Reusing a checkpoint name replaces the previous checkpoint.
- The checkpoint captures the active sandbox's disk; `--id` can be used to select a sandbox.
