SKILL.md
Service Management
Check status, update properties, and advanced service creation.
When to Use
- User asks about service status, health, or deployments
- User asks "is my service deployed?"
- User wants to rename a service or change service icon
- User wants to link a different service
- User wants to deploy a Docker image as a new service (advanced)
Note: For creating services with local code (the common case), prefer the new skill which handles project setup, scaffolding, and service creation together.
For GitHub repo sources: Use new skill to create empty service, then environment skill to configure source.repo via staged changes API.
Create Service
Create a new service via GraphQL API. There is no CLI command for this.
Get Context
railway status --json
Extract:
project.id- for creating the service
environment.id- for staging the instance config
Create Service Mutation
mutation serviceCreate($input: ServiceCreateInput!) {
serviceCreate(input: $input) {
id
name
}
}
ServiceCreateInput Fields
Field
Type
Description
projectId
String!
Project ID (required)
name
String
Service name (auto-generated if omitted)
source.image
String
Docker image (e.g., nginx:latest)
source.repo
String
GitHub repo (e.g., user/repo)
branch
String
Git branch for repo source
environmentId
String
If set and is a fork, only creates in that env
Example: Create empty service
bash <<'SCRIPT'
scripts/railway-api.sh \
'mutation createService($input: ServiceCreateInput!) {
serviceCreate(input: $input) { id name }
}' \
'{"input": {"projectId": "PROJECT_ID"}}'
SCRIPT
Example: Create service with image
bash <<'SCRIPT'
scripts/railway-api.sh \
'mutation createService($input: ServiceCreateInput!) {
serviceCreate(input: $input) { id name }
}' \
'{"input": {"projectId": "PROJECT_ID", "name": "my-service", "source": {"image": "nginx:latest"}}}'
SCRIPT
Connecting a GitHub Repo
Do NOT use serviceCreate with source.repo - use staged changes API instead.
Flow:
- Create empty service:
serviceCreate(input: {projectId: "...", name: "my-service"})
- Use
environmentskill to configure source via staged changes API
- Apply to trigger deployment
After Creating: Configure Instance
Use environment skill to configure the service instance:
{
"services": {
"<serviceId>": {
"isCreated": true,
"source": { "image": "nginx:latest" },
"variables": {
"PORT": { "value": "8080" }
}
}
}
}
Critical: Always include isCreated: true for new service instances.
Then use environment skill to apply and deploy.
For variable references, see reference/variables.md.
Check Service Status
railway service status --json
Returns current deployment status for the linked service.
Deployment History
railway deployment list --json --limit 5
Present Status
Show:
- Service: name and current status
- Latest Deployment: status (SUCCESS, FAILED, DEPLOYING, CRASHED, etc.)
- Deployed At: when the current deployment went live
- Recent Deployments: last 3-5 with status and timestamps
Deployment Statuses
Status
Meaning
SUCCESS
Deployed and running
FAILED
Build or deploy failed
DEPLOYING
Currently deploying
BUILDING
Build in progress
CRASHED
Runtime crash
REMOVED
Deployment removed
Update Service
Update service name or icon via GraphQL API.
Get Service ID
railway status --json
Extract service.id from the response.
Update Name
bash <<'SCRIPT'
scripts/railway-api.sh \
'mutation updateService($id: String!, $input: ServiceUpdateInput!) {
serviceUpdate(id: $id, input: $input) { id name }
}' \
'{"id": "SERVICE_ID", "input": {"name": "new-name"}}'
SCRIPT
Update Icon
Icons can be image URLs or animated GIFs.
Type
Example
Image URL
"icon": "https://example.com/logo.png"
Animated GIF
"icon": "https://example.com/animated.gif"
Devicons
"icon": "https://devicons.railway.app/github"
Railway Devicons: Query https://devicons.railway.app/{query} for common developer icons (e.g., github, postgres, redis, nodejs). Browse all at https://devicons.railway.app
bash <<'SCRIPT'
scripts/railway-api.sh \
'mutation updateService($id: String!, $input: ServiceUpdateInput!) {
serviceUpdate(id: $id, input: $input) { id icon }
}' \
'{"id": "SERVICE_ID", "input": {"icon": "https://devicons.railway.app/github"}}'
SCRIPT
ServiceUpdateInput Fields
Field
Type
Description
name
String
Service name
icon
String
Emoji or image URL (including animated GIFs)
Link Service
Switch the linked service for the current directory:
railway service link
Or specify directly:
railway service link <service-name>
Composability
- Create service with local code: Use
newskill (handles scaffolding + creation)
- Configure service: Use
environmentskill (variables, commands, image, etc.)
- Delete service: Use
environmentskill withisDeleted: true
- Apply changes: Use
environmentskill
- View logs: Use
deploymentskill
- Deploy local code: Use
deployskill
Error Handling
No Service Linked
No service linked. Run `railway service link` to link a service.
No Deployments
Service exists but has no deployments yet. Deploy with `railway up`.
Service Not Found
Service "foo" not found. Check available services with `railway status`.
Project Not Found
User may not be in a linked project. Check railway status.
Permission Denied
User needs at least DEVELOPER role to create services.
Invalid Image
Docker image must be accessible (public or with registry credentials).
