**Deploy OpenSRE to Railway by installing the Railway CLI, authenticating with `railway login`, provisioning Postgres and Redis services, configuring the `DATABASE_URI` and `REDIS_URI` environment variables, and executing `opensre deploy railway` to trigger the container deployment and automated health verification.**

The OpenSRE project from Tracer-Cloud provides a command-line interface for self-hosting SRE infrastructure on modern platforms. When you deploy OpenSRE to Railway, the tool orchestrates the Railway CLI to manage containerized services, inject environment variables, and verify deployment readiness through the `/ok` health endpoint.

## Prerequisites for Deploying OpenSRE to Railway

### Install and Authenticate the Railway CLI

Before running OpenSRE commands, install the Railway CLI globally and authenticate your session. The deployment logic in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py) validates these prerequisites using `is_railway_cli_installed()` and `get_railway_auth_status()`.

```bash
npm install -g @railway/cli
railway login

```

Authentication stores a JWT in `~/.railway`, enabling subsequent API calls.

### Provision Postgres and Redis Services

OpenSRE requires persistent storage and caching. Create these services via the Railway dashboard or CLI:

```bash
railway service add postgres
railway service add redis

```

These commands generate connection strings that map to the `DATABASE_URI` and `REDIS_URI` environment variables required by OpenSRE.

## Step-by-Step Deployment Process

### Configure Environment Variables

Set the required connection strings as Railway environment variables before deployment. The `deploy_to_railway()` function in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py) automatically injects these during the deployment flow.

```bash
railway variables set DATABASE_URI=postgres://user:pass@host:5432/db
railway variables set REDIS_URI=redis://default:pass@host:6379

```

### Link the Railway Project (Optional)

Associate your local repository with a specific Railway project to avoid passing `--project` flags repeatedly:

```bash
railway link --project <project-name>

```

### Execute the Deployment Command

Run the OpenSRE CLI command to trigger deployment. This executes `railway up --detach` via the `_run_command()` helper in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py).

```bash
opensre deploy railway --project <project> --service <service> --yes

```

The `--yes` flag skips interactive confirmation (implemented via `questionary`). Use `--dry-run` to preview actions without deploying.

### Verify Deployment Health

After deployment, OpenSRE polls the `/ok` endpoint using `_extract_railway_url()` to determine the public URL. The CLI outputs "Health check passed!" on HTTP 200, or displays troubleshooting hints from `RAILWAY_DATABASE_HINTS` on failure.

## Programmatic Deployment with Python

For CI/CD pipelines, import `deploy_to_railway()` directly from [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py):

```python
from opensre.app.cli.deploy import deploy_to_railway

result = deploy_to_railway(
    project_name="my-railway-project",
    service_name="opensre",
    env_vars={
        "DATABASE_URI": "postgres://...",
        "REDIS_URI": "redis://...",
        "CUSTOM_VAR": "value",
    },
    dry_run=False,
    wait_for_health=True,
)

print(f"Success: {result['success']}")
print(f"URL: {result['url']}")
print(f"Health OK: {result['health_ok']}")

```

The function returns a `DeployResult` dictionary containing `success`, `url`, `logs`, `health_ok`, and `error` fields.

## Post-Deployment Operations

Manage running services using `opensre remote ops`, which delegates to `RailwayRemoteOpsProvider` in [`app/remote/ops.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/remote/ops.py):

```bash

# Check service status and public URL

opensre remote ops --provider railway --project <project> --service <service> status

# View recent logs

opensre remote ops logs --lines 200

# Stream logs in real-time

opensre remote ops logs --follow

# Restart the service

opensre remote ops restart --yes

```

These commands wrap `railway status`, `railway logs`, and `railway restart` respectively.

## Summary

- **Deploy OpenSRE to Railway** using the `opensre deploy railway` command, which orchestrates the Railway CLI to execute `railway up --detach`.
- **Prerequisites** include installing the Railway CLI, running `railway login`, and provisioning Postgres and Redis services to generate `DATABASE_URI` and `REDIS_URI`.
- **Deployment automation** is available through the `deploy_to_railway()` function in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py), returning a typed `DeployResult` dictionary for CI/CD integration.
- **Health verification** polls the `/ok` endpoint automatically, with failure hints provided from `RAILWAY_DATABASE_HINTS`.
- **Post-deployment management** uses `opensre remote ops` commands backed by `RailwayRemoteOpsProvider` in [`app/remote/ops.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/remote/ops.py) for status checks, log streaming, and restarts.

## Frequently Asked Questions

### What are the exact prerequisites before I can deploy OpenSRE to Railway?

You must install the Railway CLI globally using `npm install -g @railway/cli`, authenticate via `railway login` to store credentials in `~/.railway`, and provision Postgres and Redis services in your Railway project. The `opensre deploy railway` command validates these prerequisites using `is_railway_cli_installed()` and `get_railway_auth_status()` functions defined in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py).

### How does the OpenSRE CLI handle environment variables for Railway deployment?

The CLI requires `DATABASE_URI` and `REDIS_URI` environment variables to connect to provisioned services. When executing `opensre deploy railway`, the `deploy_to_railway()` function in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py) automatically injects these variables into the Railway service context. You can also pass additional custom variables through the `env_vars` parameter when using the Python API.

### Can I automate OpenSRE deployment to Railway in a CI/CD pipeline?

Yes. Instead of using the CLI interactively, import `deploy_to_railway` from [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py) and invoke it with `dry_run=False` and `wait_for_health=True`. The function returns a `DeployResult` dictionary containing `success`, `url`, `health_ok`, and `logs` fields, allowing you to programmatically verify deployment success before proceeding with subsequent pipeline stages.

### How do I troubleshoot a failed health check after deploying OpenSRE to Railway?

If the `/ok` endpoint does not return HTTP 200 within the configured timeout, the CLI displays troubleshooting hints sourced from `RAILWAY_DATABASE_HINTS` in [`app/cli/deploy.py`](https://github.com/Tracer-Cloud/opensre/blob/main/app/cli/deploy.py). Common failures include missing `DATABASE_URI` or `REDIS_URI` variables, incomplete service provisioning, or network policies blocking the health endpoint. Use `opensre remote ops logs` to inspect container output and identify specific startup errors.
