Configuration

Here are the configuration options, set to the default values, for this service. If you are unsure about where this goes or what this means, we highly recommend scanning the services documentation to get a good handle on how the magicks work.

Also note that options, in addition to the build steps and overrides that are available to every service, are shown below:

Be careful when switching database type, version or credentials!

You should be careful switching database type, version or creds.

In the case of type and version, the underlying database files between these things will likely not be compatible. In the case of credentials, these are set when the container is initially created so in order to change them you need to lando destroy && lando start. Note that lando destroy will delete all the data in your database.

Ignoring this warning can prevent your database service from starting

services:
  myservice:
    type: mariadb:10.1
    portforward: false
    creds:
      user: mariadb
      password: mariadb
      database: database
    config:
      database: SEE BELOW

Port forwarding

portforward will allow you to access this service externally by assigning a port directly on your host's localhost. Note that portforward can be set to either true or a specific port but we highly recommend you set it to true unless you have pretty good knowledge of how port assignment works or you have a very compelling reason for needing a locked down port.

portforward: true will prevent inevitable port collisions and provide greater reliability and stability across Lando apps. That said, one downside of portforward: true is that Docker will assign a different port every time you restart your application. You can read more about accessing services externally over here.

tl;dr

Recommended

services:
  myservice:
    type: mariadb
    portforward: true

Not recommended

services:
  myservice:
    type: mariadb
    portforward: 3600

Setting custom credentials

You can also configure the default database, user and password. However, it is very important to note that these things get set the FIRST TIME YOU START the service and ONLY THE FIRST TIME.

This means that if you change any of the creds, you need to lando destroy and then lando start the service for the changes to take effect. This stands in contrast to the normal lando rebuild method to change config and is a consequence of persisting the database's data directory between rebuilds.

services:
  myservice:
    type: mariadb
    creds:
      user: mariadb -> myuser
      password: mariadb -> mypassword
      database: database -> db7

lando destroy -y && lando start

Also note that by default all mariadb services have a passwordless root user. DO NOT ALTER THE PASSWORD OF THE ROOT USER.

Using a custom MariaDB config file

You may need to override our default MySQL config with your own custom MySQL config.

If you do this, you must use a file that exists inside your application and express it relative to your project root as shown below:

A hypothetical project

Note that you can put your configuration files anywhere inside your application directory. We use a config directory but you can call it whatever you want such as .lando in the example below:

./
|-- config
   |-- my-custom.cnf
|-- .lando.yml

Landofile's mariadb config

services:
  myservice:
    type: mariadb
    config:
      database: config/my-custom.cnf

Getting information

You can get connection and credential information about your mariadb instance by running lando info. It may also be worth checking out our accessing services externally guide.
