Configure an external PostgreSQL database

The MOSTLY AI Helm charts include a PostgreSQL container that the application uses to store data about generators, synthetic datasets, and connectors.

If necessary, you can configure an external PostgreSQL database that your company hosts internally.

Prerequisites

Make sure that the Kubernetes cluster has access to your external PostgreSQL database.
Encode the PostgreSQL credentials in base64 format.

Steps

Edit values.yaml to configure the external PostgreSQL.
Under ### Postgresql settings, set local_deployment to false.
values.yaml
```
### Postgresql settings
PSQL:
    local_deployment: false
```
Paste the base64-encoded user and password in the psqlMostlyPass and psqlMostlyUser lines.
💡
The excerpt from values.yaml contains asterisks where you need to paste your encoded PostgreSQL user and password.
values.yaml
```
## External Postgresql database details encrypted with base64 (psql_local_deployment have to be setup to 'false')
psql_secrets:
    psqlMostlyPass: **********
    psqlMostlyUser: ******
##
```

Under ## External Postgresql database details, configure your PostgreSQL database connection details.

values.yaml

## External Postgresql database details
psql_cm:
    host: mostly-db.example.com
    mostly_app_db_name: mostly_app
    mostly_coordinator_db_name: mostly_coordinator
    mostly_keycloak_db_name: mostly_keycloak
    port: '5432'
##

Under ## Local Postgresql deployment, set the database name and port in the name and containerPort lines.

values.yaml

## Local Postgresql deployment
# name: mostly-psql
# image:
#   name: postgresql #<-- required to be updated with provided by Mostly AI repository
#   tag: 14.5.0-debian-11-r6 #<-- required to be updated with provided by Mostly AI image tag
#   imagePullPolicy: IfNotPresent
#   imagePullSecrets: mostly-docker-cfg
 
ports:
    name: mostly-db
    containerPort: 5432

Save the changes to the values.yaml file.
Go back to deploying with helm upgrade ....
