Deploy Go

Leash detects Go apps by the presence of go.mod. Just deploy from your project directory.

Detection

If your project root contains a go.mod file, Leash automatically builds and deploys it as a Go application.

Example App

main.go

package main

import (
	"encoding/json"
	"fmt"
	"net/http"
	"os"
)

func main() {
	port := os.Getenv("PORT")
	if port == "" {
		port = "8080"
	}

	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(w, "Hello from Leash!")
	})

	http.HandleFunc("/api/health", func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Type", "application/json")
		json.NewEncoder(w).Encode(map[string]string{"status": "ok"})
	})

	fmt.Printf("Server running on port %s\n", port)
	http.ListenAndServe(":"+port, nil)
}

go.mod

module my-go-service

go 1.22

Deploy
