deploy

Original：🇺🇸 English

Translated

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

Deploy code from the current directory to Railway using

railway up

.

When to Use

User asks to "deploy", "ship", "push code"
User says "railway up" or "deploy to Railway"
User wants to deploy local code changes
User says "deploy and fix any issues" (use --ci mode)

Commit Message

Always use the

-m

flag with a descriptive commit message summarizing what's being deployed:

bash

railway up --detach -m "Add user authentication endpoint"

Good commit messages:

Describe what changed: "Fix memory leak in worker process"
Reference tickets/issues: "Implement feature #123"
Be concise but meaningful: "Update deps and fix build warnings"

Modes

Detach Mode (default)

Starts deploy and returns immediately. Use for most deploys.

bash

railway up --detach -m "Deploy description here"

CI Mode

Streams build logs until complete. Use when user wants to watch the build or needs to debug issues.

bash

railway up --ci -m "Deploy description here"

When to use CI mode:

User says "deploy and watch", "deploy and fix issues"
User is debugging build failures
User wants to see build output

Deploy Specific Service

Default is linked service. To deploy to a different service:

bash

railway up --detach --service backend -m "Deploy description here"

Deploy to Unlinked Project

Deploy to a project without linking first:

bash

railway up --project <project-id> --environment production --detach -m "Deploy description here"

Requires both

--project

and

--environment

flags.

CLI Options

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)

Directory Linking

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

.

After Deploy

Detach mode

Deploying to <service>...

Use

deployment

skill to check build status (with

--lines

flag).

CI mode

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).

Composability

Check status after deploy: Use
```
service
```
skill
View logs: Use
```
deployment
```
skill
Fix config issues: Use
```
environment
```
skill
Redeploy after config fix: Use
```
environment
```
skill

Error Handling

No Project Linked

No Railway project linked. Run `railway link` first.

No Service Linked

No service linked. Use --service flag or run `railway service` to select one.

Build Failure (CI mode)

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

).

Common issues:

Missing dependencies → check package.json/requirements.txt
Build command wrong → use environment skill to fix
Dockerfile issues → check dockerfile path
