Databases

​

Introduction

Vapor allows you to easily create and manage RDS and Aurora Serverless databases directly from the Vapor UI or using the Vapor CLI. Database backups are automatically performed and you may restore a database to any point in time (down to the second) within the backup retention window.

​

Creating Databases

You may create databases using the Vapor UI or using the database CLI command. When using the CLI command, the command will prompt you for more details about the database such as its desired performance class and maximum storage space.

vapor database my-application-db

​

The Default Database

Vapor will automatically create a “vapor” database within each database instance that you create. You are free to create additional databases using the database management tool of your choice.

​

Database Types

When creating Vapor databases, you may choose from two different types of databases: fixed size and auto-scaling serverless databases.

​

Fixed Size Databases

Fixed sized databases are RDS MySQL 5.7 / RDS MySQL 8 / Postgres 13 databases that have a fixed amount of RAM and disk space. These databases may be scaled up or down after creation, but not without incurring downtime.

In addition, these databases may be publicly accessible (with a long, random password automatically assigned by Vapor) or private. Private databases may not typically be accessed from the public Internet. To access them from your local machine, you will need to create a Vapor jumpbox.

​

Serverless Databases

Serverless databases are auto-scaling Aurora MySQL 5.7 / MySQL 8.0 / Postgres 10 / Postgres 14 databases which do not have a fixed amount of RAM or disk space. Instead, these databases automatically scale based on the needs of your application. At their smallest scale, they are allocated 1GB of RAM.

​

Quick Development Databases

To quickly create a publicly accessible database of the smallest performance class, you may use the --dev flag when creating your database. These small, affordable databases are perfect for testing or staging environments:

vapor database my-test-database --dev

​

Using Databases

To attach a database to an environment, add a database key to the environment’s configuration in your vapor.yml file and deploy your application. The value of this key should be the name of the database. When the environment is deployed, Vapor will automatically inject the necessary Laravel environment variables for connecting to the database, allowing your application to start using it immediately:

id: 3
name: vapor-app
environments:
    production:
        database: my-application-db
        build:
            - 'composer install --no-dev'
        deploy:
            - 'php artisan migrate --force'

​

Connecting To Private Databases Locally

If you would like to connect to your private database from your local machine, you can either use a Vapor jumpbox in combination with a GUI database management tool or the database:shell CLI command. Jumpboxes are very small, SSH accessible servers that are placed within your private network.

​

Jumpboxes + GUI Tool

Once a jumpbox has been created, you may configure your database management tool to connect to your database through the jumpbox SSH connection:

​

Shell Command

After provisioning a jumpbox, you may use the database:shell command to quickly access a command line database shell that lets you interact with your database:

vapor database:shell my-application-db

​

Existing Databases

If you wish to use an RDS database that was not created by Vapor, you have two options:

1. Exporting and importing the contents of your existing database into a new database created by Vapor. We recommend this approach as it allows you to use your existing data within a database and network managed by Vapor.

2. Connecting your existing database to a Vapor environment.

If your existing database is publicly accessible, make sure your Vapor project is created in the same region as the database. If the existing database is private, you will need to connect your Vapor environment to the VPC your existing database belongs to. You can find instructions on how to do this in our documentation about connecting to Custom VPCs.

After connecting your existing database, you will need to configure the appropriate environment variables:

DB_HOST=
DB_PORT=
DB_DATABASE=
DB_USERNAME=
DB_PASSWORD=

When working with an AWS RDS MySQL Fixed Size databases, an additional environment variable specifying the SSL certificate authority is required:

MYSQL_ATTR_SSL_CA=/var/task/rds-combined-ca-bundle.pem

If your database is hosted by PlanetScale, the SSL certificate authority is as follows:

MYSQL_ATTR_SSL_CA=/opt/lib/curl/cert.pem

​

Database Proxies

Even though your serverless Laravel applications running on Vapor can handle extreme amounts of web traffic, traditional relational databases such as MySQL can become overwhelmed and crash due to connection limit restrictions. To solve this, you may use an RDS proxy to efficiently manage your database connections and allow many more connections than would typically be possible.

The database proxy can be added via the Vapor UI or the database:proxy CLI command:

vapor database:proxy my-application-db

Next, you may instruct an environment to use the proxy associated with the database using the database-proxy configuration option within your vapor.yml file:

id: 3
name: vapor-app
environments:
    production:
        database: my-application-db
        database-proxy: true
        build:
            - 'composer install --no-dev'
        deploy:
            - 'php artisan migrate --force'

You can delete the proxy at any time using the Vapor UI or the database:delete-proxy CLI command. Before deleting a proxy, make sure none of your applications are using the associated proxy:

vapor database:delete-proxy my-application-db

​

Database Users

When a database is created, Vapor creates a “vapor” master user. You may create additional database users, which will automatically be assigned a secure, random password, using the Vapor UI or the database:user CLI command:

vapor database:user my-application-db user-2

You may instruct an environment to connect to a database as a given user using the database-user configuration option within your vapor.yml file:

id: 3
name: vapor-app
environments:
    production:
        database: my-application-db
        database-user: user-2
        build:
            - 'composer install --no-dev'
        deploy:
            - 'php artisan migrate --force'

​

Scaling Databases

You may scale fixed size databases via the Vapor UI’s database detail screen or the database:scale CLI command. When scaling a fixed size database, the database will be unavailable, and the amount of time it takes to scale the database could vary based on the size of the database. Therefore, you should place your application in maintenance mode before beginning the scaling operation:

vapor database:scale my-application-db

​

Restoring Databases

Vapor database backups are performed automatically and you may restore databases to any point in time within the database backup retention period, which is three days by default. You can change the database backup retention period at any time via the Vapor UI’s database details screen.

Database restoration may be initiated via the Vapor UI or the database:restore CLI command:

vapor database:restore current-database-name new-database-name

When restoring a database, a new database is created with the same configuration as the previous database. Then, the previous database’s contents are restored to the new database as they existed at the exact point in time you choose. To attach the restored database to an environment, update the value of the database key in your vapor.yml file and deploy the environment.

Once you are satisfied with the database restoration, you may delete the old database.

​

Upgrading Databases

You may upgrade a Vapor managed MySQL database via the Vapor UI or the database:upgrade CLI command. When upgrading a database, a new database is created with the same configuration and credentials as the original database:

vapor database:upgrade current-database-name new-database-name

Keep in mind that major version upgrades can contain database changes that are not backward-compatible with existing applications. For that reason, we recommend that you thoroughly test the new upgraded database version before attaching it to a production environment. The original database will not be affected by this operation at any point.

Upgrading a database can take several hours for large databases. Therefore, if you plan to attach the new database to a production environment, you may want to place any affected environments in maintenance mode first. Once the newly upgraded database is available, you may start using it by attaching it to an environment.

Of course, once you are satisfied with the database upgrade, you may delete the original database.

​

Metrics

A variety of database performance metrics are available via the Vapor UI’s database detail screen or using the database:metrics CLI command:

vapor database:metrics my-application-db
vapor database:metrics my-application-db 5m
vapor database:metrics my-application-db 30m
vapor database:metrics my-application-db 1h
vapor database:metrics my-application-db 8h
vapor database:metrics my-application-db 1d
vapor database:metrics my-application-db 3d
vapor database:metrics my-application-db 7d
vapor database:metrics my-application-db 1M

​

Alarms

You may configure alarms for all database metrics using the Vapor UI. These alarms will notify you via the notification method of your choice when an alarm’s configured threshold is broken and when an alarm recovers.

​

Deleting Databases

Databases may be deleted via the Vapor UI or using the database:delete CLI command. Once a database has been deleted, it can not be recovered, so take extra caution before deleting a database:

vapor database:delete my-application-db
