multiflexi-database

provide database configuration and migration for MultiFlexi's executor, scheduler, api and web.

Installation

Install prerequisites:

sudo apt install lsb-release wget apt-transport-https bzip2

Add the VitexSoftware repository and key:

wget -qO- https://repo.vitexsoftware.com/keyring.gpg | sudo tee /etc/apt/trusted.gpg.d/vitexsoftware.gpg
echo "deb [signed-by=/etc/apt/trusted.gpg.d/vitexsoftware.gpg]  https://repo.vitexsoftware.com  $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/vitexsoftware.list
sudo apt update

Install the package for your database (replace DBTYPE with mysql, pgsql, or sqlite):

Skipping automatic migration

If you want to skip running database migrations during package installation or upgrade, set the environment variable MULTIFLEXI_NOMIGRATE before installing or upgrading the package. This is especially useful when building Docker images, so that migrations are not run during image creation.

sudo MULTIFLEXI_NOMIGRATE=1 apt install multiflexi-sqlite

When this variable is set, the multiflexi-migrator step in the post-installation scripts will be skipped.

sudo apt install multiflexi-DBTYPE

Supported database engines:

• MySQL / MariaDB (fully supported)
• PostgreSQL (fully supported)
• SQLite (fully supported)
• SQL Server (experimental support)

All MultiFlexi components are designed to work seamlessly with any of these database backends through database abstraction layers.

Encryption keys

MultiFlexi stores credential values encrypted with AES-256-GCM/CBC. Three keys are maintained in the encryption_keys table: default, credentials, and personal_data.

The EncryptionKeysSeeder initialises these keys during first install. Each key is a freshly generated 256-bit random value that is itself encrypted with ENCRYPTION_MASTER_KEY before being stored in the database.

Requirement

ENCRYPTION_MASTER_KEY (or MULTIFLEXI_MASTER_KEY) must be set in the environment or in /etc/multiflexi/database.env before the seeder is run. If the variable is absent the seeder prints an error and exits without modifying the database.

Automatic execution

The Debian postinst scripts for multiflexi-mysql, multiflexi-pgsql and multiflexi-sqlite call the seeder automatically after multiflexi-migrator:

phinx seed:run -c /usr/lib/multiflexi-database/phinx-adapter.php -s EncryptionKeysSeeder

Manual execution

export ENCRYPTION_MASTER_KEY="your-very-secret-master-key"
phinx seed:run -c /usr/lib/multiflexi-database/phinx-adapter.php -s EncryptionKeysSeeder

Idempotency

The seeder is safe to run repeatedly. Rows whose key_data already contains a real (non-placeholder) value are never touched. Only rows that are missing entirely, or that still contain the PLACEHOLDER_KEY_TO_BE_REPLACED sentinel inserted by the migration, are written.
