Use external databases

Table of Contents

local

Why

Some people or companies might have concerns with dockerized databases and rather rely on good old host-based database setups. There could already be a database cluster in your network or you rather want to use AWS RDS or other cloud-based solutions.

There are many reasons for having an external database.

Database on host os

Note

If the local database is listening on an IP address that is reachable over your current LAN, you can directly skip to: use_external_databases_database_on_network

In order to use an already existing database that is running on the host os, you need to make sure the following is met:

1. Be able to connect to the host os from inside the container

   connect_to_host_os

2. Configure your application to use the IP/CNAME of the host os

3. When starting the Devilbox, explicitly specify the service to use and exclude the databases:

   # Explicitly specify services to start (otherwise all will start)
   # Omit the database
   host> docker-compose up -d php httpd bind redis

   start_the_devilbox

Database on network

In order to use an already existing database that is running on the network, you need to make sure the following is met:

1. Configure your application to use the IP/CNAME of the database host

2. When starting the Devilbox, explicitly specify the service to use and exclude the databases:

   # Explicitly specify services to start (otherwise all will start)
   # Omit the database
   host> docker-compose up -d php httpd bind redis

   start_the_devilbox

Database on internet

In order to use an already existing database that is running on the network, you need to make sure the following is met:

1. Configure your application to use the IP/CNAME of the database host

2. When starting the Devilbox, explicitly specify the service to use and exclude the databases:

   # Explicitly specify services to start (otherwise all will start)
   # Omit the database
   host> docker-compose up -d php httpd bind redis
