You're viewing documentation for the legacy version of Firezone, now End-of-Life. View the latest docs here.
Custom External Database
Firezone uses Postgresql DB as its primary data store.
Compatibility
Firezone should work fine on Postgres versions 12 and above, but we recommend using the latest stable version whenever possible. If you find an issue with your particular version of Postgres, please open a GitHub issue .
In general, Firezone should also work fine using external Postgres-based database services like Amazon RDS. See the configuration section below for more information configuring Firezone with an external DB.
Configuring Firezone to use an external database can be complicated and error-prone. We recommend using the bundled Postgres for Omnibus-based deployments or the official Postgres Docker image for Docker-based deployments if possible.
Configure Firezone to Connect
The Firezone Docker image uses the following environment variables to connect to the DB (fields in bold required):
| Name | Description | Format | Default |
|---|---|---|---|
DATABASE_ENCRYPTION_KEY | The base64-encoded symmetric encryption key used to encrypt and decrypt sensitive fields. | base64-encoded String | None -- must be generated on install |
DATABASE_HOST | Database host | IP or hostname | postgres |
DATABASE_PORT | Database port | Integer | 5432 |
DATABASE_NAME | Name of database | String | firezone |
DATABASE_USER | User | String | postgres |
DATABASE_PASSWORD | Password | String | postgres |
DATABASE_POOL | Size of the Firezone connection pool | Integer | 10 |
DATABASE_SSL | Whether to connect to the database over SSL | Boolean | false |
DATABASE_SSL_OPTS | Map of options to send to the :ssl_opts option when connecting over SSL. See Ecto.Adapters.Postgres documentation | JSON-encoded String | {} |
DATABASE_PARAMETERS | Map of parameters to send to the :parameters option when connecting to the database. See Ecto.Adapters.Postgres documentation. | JSON-encoded String | {} |
For more information, see the environment variable reference .
The official postgres docker image can be configured by setting environment
variables for the container. See the Postgres image
documentation for more details.
The following configuration options are used to configure the bundled Postgres for Omnibus-based deployments:

|---|---|---|
default['firezone']['database']['user'] | Specifies the username Firezone will use to connect to the DB. | node['firezone']['postgresql']['username'] |
default['firezone']['database']['password'] | If using an external DB, specifies the password Firezone will use to connect to the DB. | 'change_me' |
default['firezone']['database']['name'] | Database that Firezone will use. Will be created if it doesn't exist. | 'firezone' |
default['firezone']['database']['host'] | Database host that Firezone will connect to. | node['firezone']['postgresql']['listen_address'] |
default['firezone']['database']['port'] | Database port that Firezone will connect to. | node['firezone']['postgresql']['port'] |
default['firezone']['database']['pool'] | Database pool size Firezone will use. | [10, Etc.nprocessors].max |
default['firezone']['database']['ssl'] | Whether to connect to the database over SSL. | false |
default['firezone']['database']['ssl_opts'] | Hash of options to send to the :ssl_opts option when connecting over SSL. See Ecto.Adapters.Postgres documentation. | {} |
default['firezone']['database']['parameters'] | Hash of parameters to send to the :parameters option when connecting to the database. See Ecto.Adapters.Postgres documentation. | {} |
default['firezone']['database']['extensions'] | Database extensions to enable. | { 'plpgsql' => true, 'pg_trgm' => true } |
