External MySQL

The Director stores VM, persistent disk and other information in a database. An internal database might be sufficient for your deployment; however, a highly-available external database can improve performance, scalability and protect against data loss.

Included Postgres (default)

1. Add postgres release job and make sure that persistent disk is enabled:

   jobs:
   - name: bosh
     templates:
     - {name: postgres, release: bosh}
     # ...
     persistent_disk: 25_000
     # ...
   

2. Configure postgres job, and let the Director and the Registry (if configured) use the database:

   properties:
     postgres: &database
       host: 127.0.0.1
       user: postgres
       password: postgres-password
       database: bosh
       adapter: postgres
   
     director:
       db: *database
       # ...
   
     registry:
       db: *database
       # ...

The Director is tested to be compatible with MySQL and Postgresql databases.

1. Modify deployment manifest for the Director

   properties:
     director:
       db: &database
         host: DB-HOST
         port: DB-PORT
         user: DB-USER
         password: DB-PASSWORD
         database: bosh
         adapter: postgres
   
     registry:
       db: *database
       # ...
   

   See director.db job configuration for more details.
