|

|
||||
Database initialization and migrations for PostgreSQL can be configured to run
|
||||
within the application pod by setting the project variables `DB_INITIALIZE` and
|
||||
`DB_MIGRATE` respectively.
|
||||
|
||||
If present, `DB_INITIALIZE` will be run as a shell command within an application pod as a helm
|
||||
post-install hook. Note that this means that if any deploy succeeds,
|
||||
`DB_INITIALIZE` will not be processed thereafter.
|
||||
|
||||
If present, `DB_MIGRATE` will be run as a shell command within an application pod as
|
||||
a helm pre-upgrade hook.
|
||||
|
||||
For example, in a Rails application:
|
||||
|
||||
* `DB_INITIALIZE` can be set to `cd /app && RAILS_ENV=production
|
||||
bin/setup`
|
||||
* `DB_MIGRATE` can be set to `cd /app && RAILS_ENV=production bin/update`
|
||||
|
||||
NOTE: **Note:**
|
||||
The `/app` path is the directory of your project inside the docker image
|
||||
as [configured by
