Postgresql helm chart with initdbScripts

Question

I have the following template:

image:
  tag: "13"
postgresqlUsername: postgres
postgresqlPassword: "12345678"
postgresqlDatabase: postgres
initdbScripts:
  init: |
    CREATE USER my_app WITH PASSWORD '12345678';
    CREATE DATABASE my_db;
    GRANT ALL PRIVILEGES ON DATABASE my_db TO my_app;

Running helm install postgresql bitnami/postgresql -f conf/postgresql/postgresql.yaml
spins up the deployment with the configmap correctly, but the database "my_db" and the user "my_app" were not created.

I need to use this setup to create multiple databases and users (hence postgresqlDatabase is not enough).

How should I work with the initdbScripts or what am I doing wrong?

Answer 1

The script needs a file extension so it knows how to run.

Add .sql to init :

image:
  tag: "13"
postgresqlUsername: postgres
postgresqlPassword: "12345678"
postgresqlDatabase: postgres
initdbScripts:
  init.sql: | # <-- Here
    CREATE USER my_app WITH PASSWORD '12345678';
    CREATE DATABASE my_db;
    GRANT ALL PRIVILEGES ON DATABASE my_db TO my_app;
