railwayWhen the environment config supports `cdn`, add the block to manage a service’s edge caching and reconcile it with the environment. Pull a cached service’s config to see the serialized block; defaults are omitted.
cdn:
enabled: true
defaultTtlSeconds: <seconds>
htmlCaching: <mode>
staleWhileRevalidate: <boolean>
purgeOnDeploy: <mode>If the linked Railway service has a cron schedule, use `railway cron list` to view recent runs or `railway cron run --yes` to enqueue an off-schedule run.
railway cron listWhen you need to target a specific Railway environment, add `--environment <ENV>` to `railway config plan`, `apply`, or `pull`. `<ENV>` can be the environment name or ID.
railway config plan --environment <ENV>When IaC should not own some or all project variables, set the project-level `variables` policy: `ignore` excludes matching keys from both sides of the diff, and `managed: false` prevents variable sets and deletes. A service declaring `env` or `variables` is an error when `managed` is false.
project("example", { variables: { managed: true, ignore: ["SECRETS_*", "web/*"] }, resources: [...] })When configuring tracing for a Railway environment, set the service’s `tracing` switches in IaC or enable tracing for that environment with `railway trace`.
const api = service("api", { tracing: { enabled: true, autoInstrumentation: true } });When debugging a Railway project, use `railway trace status` to inspect tracing settings and `railway trace list` / `railway trace get <TRACE_ID>` to inspect traces. [Railway CLI trace docs](https://docs.railway.com/cli/trace)
railway trace statusWhen an authoring file is missing or you need to change named IaC ownership, inspect the linked environment’s partials, then release selected ownership or transfer it to another partial; clear all named ownership, update the authoring configuration, and run a fresh plan before whole-project planning. These commands change ownership metadata only.
railway config partials list
railway config partials list --jsonWhen starting a Railway coding-agent session for repository work, run `railway code` to open `railway-agent-tui` on a fresh VM. In the picker, press `n` from the main screen or Option+N from an existing VM, session, or focused terminal; use `p` to choose the project and environment, and optionally toggle **Use bootstrap** and press `b` to choose one.
railway codeWhen creating or forking a sandbox that needs public HTTPS routes and private-network access, pass `--private-network` and repeat `--domain [PREFIX:]PORT` for each route. Read the published URLs from human or JSON output; if routes are still publishing, check `railway sandbox list` for the URLs.
railway sandbox create --private-network --domain <PORT>When starting a repository coding session, save and select a ready bootstrap with `railway ca bootstrap`, or pass `--no-bootstrap` for a clean VM. Launch with `railway code` or `railway ca create` using the selected bootstrap option.
railway ca bootstrap save <name> --agent <agent-name> [--default]
