This skill should be used when the user wants to push code to Railway, says "railway up", "deploy", "deploy to railway", "ship", or "push". For initial setup or creating services, use new skill. For Docker images, use environment skill.
Deploy code from the current directory to Railway using railway up.
Always use the -m flag with a descriptive commit message summarizing what's being deployed:
railway up --detach -m "Add user authentication endpoint"
Good commit messages:
Starts deploy and returns immediately. Use for most deploys.
railway up --detach -m "Deploy description here"
Streams build logs until complete. Use when user wants to watch the build or needs to debug issues.
railway up --ci -m "Deploy description here"
When to use CI mode:
Default is linked service. To deploy to a different service:
railway up --detach --service backend -m "Deploy description here"
Deploy to a project without linking first:
railway up --project <project-id> --environment production --detach -m "Deploy description here"
Requires both --project and --environment flags.
| Flag | Description |
|---|---|
-m, --message <MSG> | Commit message describing the deploy (always use this) |
-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 environment skill, then deploy normally with railway up.
Deploying to <service>...
Use 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 deployment skill with --lines flag (never stream).
service skilldeployment skillenvironment skillenvironment skillNo 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).
