This tutorial show you how to deploy your Spring Boot application with PostgreSQL database. Let's go!

Before you begin, this guide assumes the following:

• Your Operating System is macOS / Windows / Linux
• You have a Github or Gitlab account

Steps to deploy Spring Boot with Qovery

• Web
• CLI

Sign in to the Qovery web interface.

Deployment

Spring Boot sample application

Get a local copy of the Spring Boot sample project by forking it.

Configure your project

To deploy your Spring Boot application connected to a PostgreSQL, you need to have a .qovery.yml file, and a Dockerfile (both provided in the sample project) at the root of your project.

The .qovery.yml file describes all the dependencies that your application needs (e.g., PostgreSQL) to work smoothly

In this example we are using PostgreSQL v11.5

After forking the sample application, you can check the content of .qovery.yml:

$ cat .qovery.yml

.qovery.yml

application:
  name: my-application
  project: my-project
  publicly_accessible: true
databases:
- type: postgresql
  version: "11.5"
  name: my-db
routers:
- name: main
  routes:
  - application_name: my-application
    paths:
    - /

Authorize the Qovery Github application to get access to your Github account. Once done, all new commits you push to your forked repository will trigger new deployments of the application.

Connect Spring Boot to PostgreSQL

Credentials of your database are available via environment variables. Qovery injects environment vars at the runtime.

Qovery does not inject any variable in your .env file, this is to be done on your side

To list all the environment variables available to your application, execute

# List all environment variables
$ qovery project env list

Output

SCOPE    | KEY                                                      | VALUE
BUILT_IN | QOVERY_JSON_B64                                          | <base64>
BUILT_IN | QOVERY_BRANCH_NAME                                       | master
BUILT_IN | QOVERY_IS_PRODUCTION                                     | true
BUILT_IN | QOVERY_MY_APPLICATION_HOSTNAME                           | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_DATABASE                           | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_PASSWORD                           | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_USERNAME                           | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_PORT                               | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_FQDN                               | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_HOST                               | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_CONNECTION_URI_WITHOUT_CREDENTIALS | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_CONNECTION_URI                     | <hidden>
BUILT_IN | QOVERY_DATABASE_MY_DB_VERSION                            | 11.5
BUILT_IN | QOVERY_DATABASE_MY_DB_TYPE                               | PostgreSQL
BUILT_IN | QOVERY_DATABASE_MY_DB_NAME                               | my-db

The sample application is preconfigured to use those environment variables to connect to the database.

Forking the application with .qovery.yml and a Dockerfile should trigger app deployment.

See the deployment status by executing:

# Show your deployment status
$ qovery status

Output

BRANCH NAME | STATUS  | ENDPOINTS                                   | APPLICATIONS    | DATABASES
master      | running | https://main-abcdefgh12345678-gtw.qovery.io | my-application  | my-db

APPLICATION NAME  | STATUS  | DATABASES
my-application    | running | my-db

DATABASE NAME    | STATUS  | TYPE       | VERSION | ENDPOINT | PORT     | USERNAME | PASSWORD | APPLICATIONS
my-db            | running | POSTGRESQL      | 11.5     | <hidden> | <hidden> | <hidden> | <hidden> | my-application

When your application status is running, you can use a browser or curl to access its endpoints.

Trigger a new deployment

Now, you can play with the sample application and commit & push your changes. Qovery detects your actions and triggers new builds and application deployments. Any change you make will be reflected in your deployed application automatically.

Bonuses (optional)

Deploy the application on dev environments

Qovery has a compelling feature known as "environments". Qovery supports the deployment of isolated development environments that reflect your Git branches. Environments are complete copies of all of your data, application, and services like databases. The Environment is useful for testing changes in isolation before merging them to your main branch.

So, do you want to create a new feature, fix a bug, or make modifications without impacting the production or any other important environment? Type the following commands:

$ git checkout -b feat_foo
$ git push -u origin feat_foo

# show deployment status
$ qovery status

Output

BRANCH NAME | STATUS  | ENDPOINTS                                   | APPLICATIONS    | DATABASES
feat_foo    | running | https://main-yenr7erjbs87dk4m-gtw.qovery.io | my-application  | my-db

APPLICATION NAME      | STATUS  | DATABASES
docker-simple-example | running | my-db

DATABASE NAME  | STATUS  | TYPE       | VERSION | ENDPOINT | PORT     | USERNAME | PASSWORD | APPLICATIONS
my-db          | running | PostgreSQL      | 11.5     | <hidden> | <hidden> | <hidden> | <hidden> | my-application

Multiple Environments

Test the Spring Boot application locally

The Qovery motto is: if your application runs locally, it runs well on Qovery, too. To test if your application is running locally, execute the following command:

The Docker runtime is required

$ qovery run

Note: qovery run connects your application to the PostgreSQL database on Qovery.
