Deploy a Quarkus App for Free on Railway (No Credit Card)


To deploy a Quarkus app on Railway(For free registration click here), you need to follow these steps:

1. Prepare your Quarkus Application

Ensure that your Quarkus app is working locally. You can test this by running:

./mvnw quarkus:dev

Make sure it works as expected before deploying.

2. Set Up Railway Project

  • If you don’t already have a Railway account, sign up at Railway(click here for registration).
  • Once logged in, create a new project on Railway.

3. Push Your Quarkus App to GitHub

Railway can integrate with GitHub to deploy your app automatically. Push your Quarkus project to a GitHub repository if it's not already there.

4. Create a New Railway Project

  • In your Railway dashboard, click on "New Project."
  • Choose the GitHub integration and connect it to your GitHub repository.
  • Select the repository containing your Quarkus app.

5. Add a Railway Deployment Configuration

Railway automatically detects Java applications and uses the appropriate buildpack. However, you may need to configure the deployment script.

  • In your application.properties (or application.yml), make sure the HTTP port is set to 8080:

    quarkus.http.port=8080

  • If you're using a build tool like Maven, ensure your app is packaged as a JAR or native image that can be run on Railway.

6. Configure Dockerfile (if necessary)

If Railway doesn't automatically detect your Quarkus app, you can create a Dockerfile to guide the deployment process.

Here’s a basic Dockerfile for a Quarkus app:

# Use OpenJDK 17 as base image
FROM openjdk:17-jdk-slim as build

# Set working directory
WORKDIR /app

# Copy the pom.xml and download dependencies (Optional but speeds up builds)
COPY pom.xml ./
RUN ./mvnw dependency:go-offline

# Copy the project files
COPY . .

# Build the application
RUN ./mvnw clean package -DskipTests

# Run the app
FROM openjdk:17-jdk-slim
WORKDIR /app
COPY --from=build /app/target/*-runner.jar app.jar
ENTRYPOINT ["java", "-jar", "app.jar"]

7. Configure Environment Variables

  • If your Quarkus app requires any environment variables (like database URLs, API keys, etc.), you can add them in Railway’s environment settings.

8. Deploy the Application

  • Railway should automatically start building and deploying your application.
  • You can track the progress in the Railway dashboard.

9. Access the Application

  • After deployment, Railway will provide you with a URL to access your Quarkus app.

By following these steps, your Quarkus app should be deployed on Railway.

Learn Java 8 streams with an example - print odd/even numbers from Array and List

Example 1: Java 8 program to print odd numbers from a List   import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; /*Java 8 Program to find Odd Numbers from a List*/ public class DriverClass { public static void main( String [] args) { List < Integer > numbers = Arrays. asList( 1 , 4 , 8 , 40 , 11 , 22 , 33 , 99 ); List < Integer > oddNumbers = numbers.stream(). filter(o -> o % 2 != 0 ). collect(Collectors.toList()); System.out.println(oddNumbers); } } 1. Initialize List using Arrays.asList() method. Java's built-in Arrays.asList() method converts an array into a list. This method takes an array as an argument and returns a List object. 2.  Java List interface provides stream() method which returns a sequential Stream with list of Integer as its source. 3. The Java stream filter(...

Java Stream API - How to convert List of objects to another List of objects using Java streams?

Image
In this section, we will show you how to convert a List of objects to another List of objects in Java using the Java streams map(). The ‘map’ method maps each element to its corresponding result. Java Stream API   The Java Stream API provides a functional programming approach over the object oriented capabilities of Java. It is used for processing collections of objects. The Stream in Java can be defined as a sequence of elements from a source List, Set or Array. Most of the stream operations return a Stream. This avails engender a chain of stream operations(stream pipe-lining). The streams withal support the aggregate or terminal operations on the elements. for example, finding the sum or maximum element or finding the average etc...Stream operations can either be executed sequentially or parallel. when performed parallelly, it is called a parallel stream.   Stream map() Method   The Java 8 Stream map() is an intermediate operation. It converts Stream<obj1> to Str...

Top 5 Java ORM tools - 2024

Image
  The term ORM refers to object-relational mapping, which uses objects to adapt programming languages to database systems while allowing them to function with SQL and object-oriented programming ideas. Any kind of database management system that can accomplish object mapping to the table in the virtual system is suitable for the implementation of ORM. Java has a wide variety of ORM tools, some of which are mentioned below: 1. Hibernate Hibernate is a lightweight, open-source, non-invasive Java ORM (Object-Relational Mapping) framework that allows developers to create objects that function independently of database software and create persistence logic in any Java or JavaEE application. It offers an abstraction layer, so developers don't have to bother about implementations; Hibernate handles these tasks internally, such as connecting to databases and creating queries to carry out CRUD operations, among other things. Persistence logic development is done with it. Persistence logic r...

Java - Blowfish Encryption and decryption Example

Image
Blowfish is an encryption method developed by Bruce Schneier in 1993 as an alternative to the DES encryption method. It is significantly faster than DES and provides good encryption speed, although no effective cryptanalysis technique has been found to date. It is one of the first secure block ciphers that is not protected by any patents and is therefore freely available for anyone to use. This is a symmetric block cipher algorithm. Block size: 64 bits Key size: variable size from 32 to 448 bits number of subsections: 18 [P-array] number of rounds: 16 number of substitution blocks: 4 [each with 512 records of 32 bits each] develop  Example 1: Encryption and decryption using Blowfish import java.io.UnsupportedEncodingException; import java.nio.charset.Charset; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.util.Base64; import javax.crypto.BadPaddingException; import javax.crypto.Cipher; import javax.crypto.IllegalBlockSiz...
