# Deploy & run with Qovery

# How it works ?

Qovery (opens new window) is a startup that offers free hosting for your project (free server & a free database) with an amazingly simple way to deploy: you push your code to git and Qovery handles the rest.

This is how we use it:

  • Create a project on github.
  • Create an account on Qovery.
  • Tell Qovery which repo to use and what kind of database you need.
  • Push code to github!

From now on, everytime you will push your code to github, Qovery will package and deploy it to your server.

# Create your bot

# Create & clone the repository

On my github account straumat, I created a private project named qovery-test.

The first step is to retrieve the project from Github on your computer:

git clone git@github.com:straumat/qovery-test.git

# Create the bot

Create a simple trading bot using one of Cassandre archetypes:

mvn -B archetype:generate -DarchetypeGroupId=tech.cassandre.trading.bot \
-DarchetypeArtifactId=cassandre-trading-bot-spring-boot-starter-basic-archetype \
-DarchetypeVersion=4.2.0 \
-DgroupId=com.example \
-DartifactId=qovery-test \
-Dversion=1.0-SNAPSHOT \

# Configure the bot

# Database connection

Edit src/main/resources/application.properties to configure the database:, we will use environment variables that qovery will pass to our application:

# Exchange configuration.
# Modes.
# Exchange API calls rates (ms or standard ISO 8601 duration like 'PT5S').
# Database configuration.

# Add the PostgreSQL driver

To connect to a PostgreSQL server, you need to add the JDBC driver to your project. Edit your pom.xml and add:


# Configure jar final name

To make things more simple to build the Docker image required by qovery, we add this in our pom in the build section:


This will ensure that the jar created by the maven process will have the name qovery-test.

# Dockerfile

When pushed to Github, qovery will retrieve your sources and build the Dockerfile at the root of your project.

This is our Dockerfile, it has two steps:

  • First, we use a maven docker image to build our application and creates a spring boot jar.
  • Second, we use an openjdk11 image, and we put our jar in it.
# Install maven and copy project for compilation.
FROM maven:3.6.3-openjdk-11-slim as build
WORKDIR /build  
# Copy just pom.xml (dependencies and dowload them all for offline access later - cache layer).
COPY pom.xml .
RUN mvn dependency:go-offline -B
# Copy source files and compile them (.dockerignore should handle what to copy).
COPY . .
RUN mvn -DskipTests=true package spring-boot:repackage

# Creates our image.
FROM adoptopenjdk/openjdk11 as runnable
COPY --from=build /build/target/qovery-test.jar app.jar
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]

# Push to github

The last step is to commit and push the project to Github:

cd qovery-test
git add *
git commit -m "first commit"
git branch -M main
git push -u origin main

# Configure Qovery

Connect to Qovery (opens new window) and signup, then go to the project menu and click on create a new project.

qovery - Create a project

Enter your project name (qovery-test):

qovery - Configure the project

Now, create an application with the name (qovery-test-app) and choose I have an application on the next screen:

qovery - Create an application

Then, select the github project you want to deploy to Qovery:

qovery - Select Github project

Choose the type of application you have (java):

qovery - Select application type

Choose the type of database (PostgreSQL):

qovery - Select database type

Choose the name of the database (qovery-test-database):

qovery - Configure database

Now, check everything is ok the summary page and press create !

qovery - Deployment summary

Qovery will now connect to your repo, creates a configuration file, creates your server and your database, retrieve your sources, build the docker image and run it ! That's it.


Qovery added a configuration file named .qovery.yml at the root of your repository.
