This Acorn provides a MariaDB database through the Acorn service interface. You can use this Acorn to create a database for your application during development. This launches a single MariaDB container backed by a persistent volume.
The username and passwords for the root and db_user are randomly generated and stored in the Acorn's secret. The db_user is granted all privileges to the database created at startup. Updates to the --db-name and --username flags will not be applied to the database after the first run.
The version of this Acorn is the version of the MariaDB database server and the Acorn build number for that version. For example, 10.11.6-0 is MariaDB version 10.11.6 and Acorn build number 0. If there is a breaking change related to the packaging of the Acorn, the Acorn build number will be incremented like so: 10.11.6-1.0.
The examples folder of this repository contains a sample application that uses this Acorn. The application is a simple Python Flask application that uses the MariaDB database to store and retrieve data.
To use this image, add the following to your Acornfile:
...
services: db: image: "ghcr.io/acorn-io/mariadb:v#.#.#-#"
...
You can customize the database and username name by adding service args to the definition like so:
...
services: db: {
image: "ghcr.io/acorn-io/mariadb:v#.#.#-#"
serviceArgs: {
dbName: "wp"
username: "wp_user"
}
}
...
To connect these services to your container, you can use the following settings:
services: db: image: "ghcr.io/acorn-io/mariadb:v#.#.#-#"
containers: app: {
image: "nginx"
env: {
DB_HOST: "@{service.db.address}"
DB_PORT: "@{service.db.port.3306}"
DB_NAME: "@{service.db.data.dbName}"
DB_ADMIN_USER: "@{service.db.secrets.admin.username}"
DB_ADMIN_PASS: "@{service.db.secrets.admin.password}"
DB_USER: "@{service.db.secrets.user.username}"
DB_PASS: "@{service.db.secrets.user.password}"
}
}
The above environment variables are an example, you need to use the correct environment variables for your application.
