Deploy Go on Your Own Server
Deploy Go web applications as minimal container images. Go compiles to a single static binary — your production image can be under 20 MB with near-instant startup.
Quickstart
From your project root, deploy with your preferred package manager:
npx @temps-sdk/cli up
Temps detects your go.mod, compiles your binary with go build, and runs it in a minimal Alpine container. Zero cold starts.
What Temps Handles Automatically
| Feature | How Temps handles it |
|---|---|
| Build | go build -o app ./... |
| Image | Multi-stage build: builder + minimal Alpine |
| Image size | Typically < 20 MB |
| HTTPS | Let's Encrypt, auto-renewed |
| Port | PORT env var injected, defaults to 8080 |
| Health checks | HTTP health check on your configured path |
| Startup | Near-instant — static binary, no runtime |
Dockerfile (optional)
Temps auto-generates a Dockerfile for Go projects. If you want full control, add your own:
# Build stage
FROM golang:1.22-alpine AS builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN go build -o app ./...
# Run stage
FROM alpine:latest
RUN apk add --no-cache ca-certificates
WORKDIR /app
COPY --from=builder /app/app .
EXPOSE 8080
CMD ["./app"]
Reading PORT from Environment
Make sure your server reads the PORT environment variable:
port := os.Getenv("PORT")
if port == "" {
port = "8080"
}
log.Fatal(http.ListenAndServe(":"+port, nil))
Managed PostgreSQL
Add a database from Project → Services → Add Service → PostgreSQL:
npx @temps-sdk/cli environments vars set DATABASE_URL "postgres://user:pass@host/db" -e production
Platform behavior
These rules apply to every app deployed on Temps, regardless of framework.
The one requirement: your app must listen on the port in the PORT environment variable and bind to 0.0.0.0 — not localhost or 127.0.0.1. Temps runs your app in a container and routes traffic from the host, so an app bound to localhost only accepts connections from inside the container and will fail its health check.
Health checks
After your container starts, Temps sends HTTP GET requests to verify it is healthy before routing traffic to it.
- Path:
/(the root of your application) - Success: 2 consecutive responses with a 2xx or 3xx status code
- Timeout: 300 seconds (5 minutes) for the app to become healthy
- Retry interval: every 5 seconds
Connection errors while the app is still starting are retried without penalty. If the app returns 4xx or 5xx errors for 60 consecutive seconds, the deployment fails. Customize the check by adding a .temps.yaml to your repository root:
health:
path: /health
status: 200
interval: 30
timeout: 5
retries: 3/health endpoint that returns a simple 200. This avoids issues where / requires authentication or returns a redirect.Auto-injected environment variables
Temps injects these variables into every deployment automatically:
| Variable | Value | Description |
|---|---|---|
PORT | Resolved port | The port your app must listen on |
HOST | 0.0.0.0 | Bind address |
SENTRY_DSN | Auto-generated | Error tracking endpoint |
TEMPS_API_URL | Your Temps URL | Platform API endpoint |
TEMPS_API_TOKEN | Deployment token | Authentication for Temps SDKs |
OTEL_EXPORTER_OTLP_ENDPOINT | Your Temps OTLP URL | OpenTelemetry trace collection |
OTEL_SERVICE_NAME | Project name | Service identifier for traces |
You do not need to configure these manually. They are available in process.env (Node.js), os.environ (Python), os.Getenv (Go), and the equivalent in other languages.
