Deploy code to Railway using "railway up". Use when user wants to push code, says "railway up", "deploy", "ship", or "push". For initial setup or creating services, use railway-new skill. For Docker images, use railway-environment skill.
Deploy code from the current directory to Railway using railway up.
Starts deploy and returns immediately. Use for most deploys.
railway up --detach
Streams build logs until complete. Use when user wants to watch the build or needs to debug issues.
railway up --ci
Default is linked service. To deploy to a different service:
railway up --detach --service backend
Deploy to a project without linking first:
railway up --project <project-id> --environment production --detach
Requires both --project and --environment flags.
| Flag | Description |
|---|---|
-d, --detach | Don't attach to logs (default) |
-c, --ci | Stream build logs, exit when done |
-s, --service <NAME> | Target service (defaults to linked) |
-e, --environment <NAME> | Target environment (defaults to linked) |
-p, --project <ID> | Target project (requires --environment) |
[PATH] | Path to deploy (defaults to current directory) |
Railway CLI walks UP the directory tree to find a linked project. If you're in a subdirectory of a linked project, you don't need to relink.
For subdirectory deployments, prefer setting rootDirectory via the railway-environment skill, then deploy normally with railway up.
Deploying to <service>...
Use railway-deployment skill to check build status (with --lines flag).
Build logs stream inline. If build fails, the error will be in the output.
Do NOT run railway logs --build after CI mode - the logs already streamed. If you need
more context, use railway-deployment skill with --lines flag (never stream).
No Railway project linked. Run `railway link` first.
No service linked. Use --service flag or run `railway service` to select one.
The build logs already streamed - analyze them directly from the railway up --ci output.
Do NOT run railway logs after CI mode (it streams forever without --lines).
