Deploy a Beego App

Beego is a high-performance, open-source web framework designed for building robust applications in Go (Golang). It is used for rapid development of enterprise apps, including RESTful APIs, web apps and backend services.

This guide covers how to deploy a Beego app to Railway in four ways:

  1. One-click deploy from a template.
  2. From a GitHub repository.
  3. Using the CLI.
  4. Using a Dockerfile.

Now, let's create a Beego app!

Create a Beego App

Note: If you already have a Beego app locally or on GitHub, you can skip this step and go straight to the Deploy Beego App to Railway.

To create a new Beego app, ensure that you have Go and Bee tool installed on your machine.

Run the following command in your terminal to create a new Beego app and install all dependencies:

bee new helloworld
cd helloworld
go mod tidy

A new Beego app will be provisioned for you in the helloworld directory.

Configure Database

Run go get github.com/lib/pq in your terminal to install the Go Postgres driver.

Create a database, helloworld_dev in your local Postgres instance.

Open the main.go file and modify the content to the code below:

package main

import (
	"fmt"
	_ "helloworld/routers"

	_ "github.com/lib/pq"

	"github.com/beego/beego/v2/client/orm"
	beego "github.com/beego/beego/v2/server/web"
)

// Users -
type Users struct {
	ID        int    `orm:"column(id)"`
	FirstName string `orm:"column(first_name)"`
	LastName  string `orm:"column(last_name)"`
}

func init() {
	// set default database
	orm.RegisterDriver("postgres", orm.DRPostgres)

	// set default database
	orm.RegisterDataBase("default", "postgres", "postgres://unicodeveloper:@localhost/helloworld_dev?sslmode=disable")

	// register model
	orm.RegisterModel(new(Users))

	// create table
	orm.RunSyncdb("default", false, true)
}

func main() {
	o := orm.NewOrm()

	// Create a slice of Users to insert
	users := []Users{
		{FirstName: "John", LastName: "Doe"},
		{FirstName: "Jane", LastName: "Doe"},
		{FirstName: "Railway", LastName: "Deploy Beego"},
	}

	// Iterate over the slice and insert each user
	for _, user := range users {
		id, err := o.Insert(&user)
		if err != nil {
			fmt.Printf("Failed to insert user %s %s: %v\n", user.FirstName, user.LastName, err)
		} else {
			fmt.Printf("Inserted user ID: %d, Name: %s %s\n", id, user.FirstName, user.LastName)
		}
	}

	beego.Run()
}

Replace this postgres://username:@localhost/helloworld_dev?sslmode=disable with the appropriate URL for your local Postgres database.

Code Summary:

  • The Users struct defines the schema for the users table in the database.
  • The init() function registers the Postgres driver, registers the Users model, and automatically creates the users table in the database. If any errors occur while inserting users, they are logged.
  • The main() function creates an ORM instance, defines sample user data (first name and last name), inserts the data into the users table, and starts the Beego web server to serve your app.

Run the Beego App Locally

To start your app, run:

bee run

Once the app is running, open your browser and navigate to http://localhost:8080 to view it in action.

In your terminal, you’ll see logs indicating that the user data is being inserted. Head over to your database, and you should see the users table populated with the seeded data.

Prepare Beego App for Deployment

  1. Open the conf/app.conf file and add an environment variable, DATABASE_URL to it.
db_url = ${DATABASE_URL}
  1. Head over to the main.go file and make some modifications to the way we retrieve the Postgres database url. The init() function should look like this:
func init() {
	// set default database
	orm.RegisterDriver("postgres", orm.DRPostgres)

	// set default database
	dbURL, err := beego.AppConfig.String("db_url")
	if err != nil {
		log.Fatal("Error getting database URL: ", err)
	}

	orm.RegisterDataBase("default", "postgres", dbURL)

	// register model
	orm.RegisterModel(new(Users))

	// create table
	orm.RunSyncdb("default", false, true)
}

Deploy the Beego App to Railway

Railway offers multiple ways to deploy your Beego app, depending on your setup and preference.

One-Click Deploy From a Template

If you’re looking for the fastest way to get started, the one-click deploy option is ideal.

Click the button below to begin:

Deploy on Railway

We highly recommend that you eject from the template after deployment to create a copy of the repo on your GitHub account.

Note: You can also choose from a variety of Beego app templates created by the community.

Deploy From the CLI

  1. Install the Railway CLI:

  2. Initialize a Railway Project:

    • Run the command below in your Beego app directory. 
      railway init
    • Follow the prompts to name your project.
    • After the project is created, click the provided link to view it in your browser.

  3. Add a Postgres Database Service:

    • Run railway add -d postgres.
    • Hit Enter to add it to your project.
    • A database service will be added to your Railway project.

  4. Add a Service and Environment Variable:

    • Run railway add.
    • Select Empty Service from the list of options.
    • In the Enter a service name prompt, enter app-service.
    • In the Enter a variable prompt, enter DATABASE_URL=${{Postgres.DATABASE_URL}}.

    Note: Explore the Railway CLI reference for a variety of options.

  5. Deploy the Application:

    • Run railway up to deploy your app.
      • This command will scan, compress and upload your app's files to Railway. You’ll see real-time deployment logs in your terminal.
    • Once the deployment is complete, we can proceed to generate a domain for the app service.

  6. Set Up a Public URL:

    • Run railway domain to generate a public URL for your app.
    • Visit the new URL to see your app live in action!

Deploy From a GitHub Repo

To deploy a Beego app to Railway directly from GitHub, follow the steps below:

  1. Create a New Project on Railway:

    • Go to Railway to create a new project.

  2. Deploy from GitHub:

    • Select Deploy from GitHub repo and choose your repository.
      • If your Railway account isn’t linked to GitHub yet, you’ll be prompted to do so.

  3. Add Environment Variables and Provision a Database Service:

    • Click Add Variables, but hold off on adding anything just yet. First, proceed with the next step.
    • Right-click on the Railway project canvas or click the Create button, then select Database and choose Add PostgreSQL.
      • This will create and deploy a new PostgreSQL database for your project.
    • Once the database is deployed, you can return to adding the necessary environment variables:
      • DATABASE_URL: Set the value to ${{Postgres.DATABASE_URL}} (this references the URL of your new Postgres database). Learn more about referencing service variables.

  4. Deploy the App Service:

    • Click Deploy on the Railway project canvas to apply your changes.

  5. Verify the Deployment:

    • Once the deployment completes, go to View logs to check if the server is running successfully.

    Note: During the deployment process, Railway will automatically detect that it’s a Go app.

  6. Set Up a Public URL:

    • Navigate to the Networking section under the Settings tab of your new service.
    • Click Generate Domain to create a public URL for your app.

Use a Dockerfile

  1. Create a Dockerfile in the Beego app's root directory.

  2. Add the content below to the Dockerfile:

    # Use the Go 1.22 official image
# https://hub.docker.com/_/golang
FROM golang:1.22

# Create and change to the app directory.
WORKDIR /app

# Copy local code to the container image.
COPY . ./

# Install project dependencies
RUN go mod download

# Build the app
RUN go build -o app

# Run the service on container startup.
ENTRYPOINT ["./app"]

  3. Either deploy via the CLI or from GitHub.

Railway automatically detects the Dockerfile, and uses it to build and deploy the app.

Note: Railway supports also deployment from public and private Docker images.

This guide covers the main deployment options on Railway. Choose the approach that suits your setup, and start deploying your Beego apps seamlessly!
