[D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

GitHub user echidnal created a discussion: Superset 6.1.0.rc2 not using postgres as meta database

Hi All,

I'm assuming I have a config wrong but can't find it.  I'm trying to spin up a more production worthy docker setup.  I've built my own image and made sure the postgres db driver is installed. And confirmed this by binding a database and data set to the same postgres db in the docker it should be using for the meta database.

The docker-compose.yml and the custom superset_config.py are being pulled in by Git to the docker server.

Based on what I am seeing -- empty postgres db AND the logs -- it seems to me that Superset is using SQLite DB and not connecting to the postgres db for the meta database.  Though I can't find a 100% way to confirm this.

I'm editing and modifying a docker-compose.yml I found on the internet.

My docker-compose.yml:

`version: "3.8"

  &superset-volumes # /app/pythonpath_docker will be appended to the PYTHONPATH in the final container
  #- ./docker:/app/docker

And here is where I may be making a mistake. I thought the superset_config.py is more of an override than needing ALL the settings in it. I have only put in items I know I need to set and removed the rest.  I'm wondering if I need more in this file and that may be my issue:

`import logging
import os
import sys
 
FEATURE_FLAGS = {"ALERT_REPORTS": True, "DATASET_FOLDERS": True, "DASHBOARD_RBAC": True}
RATELIMIT_STORAGE_URI = "redis://superset-redis:6379/0"
 
MAPBOX_API_KEY = 'CUSTOMKEY'
 
from flask_appbuilder.security.manager import AUTH_DB,AUTH_LDAP
LDAP Settings not shared but working
`
And lastly the logs of the container:

Re: [D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

Posted by "echidnal (via GitHub)" <gi...@apache.org>.
GitHub user echidnal edited a discussion: Superset 6.1.0.rc2 not using postgres as meta database

Hi All,

I'm assuming I have a config wrong but can't find it.  I'm trying to spin up a more production worthy docker setup.  I've built my own image and made sure the postgres db driver is installed. And confirmed this by binding a database and data set to the same postgres db in the docker it should be using for the meta database.

The docker-compose.yml and the custom superset_config.py are being pulled in by Git to the docker server.

Based on what I am seeing -- empty postgres db AND the logs -- it seems to me that Superset is using SQLite DB and not connecting to the postgres db for the meta database.  Though I can't find a 100% way to confirm this.

I'm editing and modifying a docker-compose.yml I found on the internet.

My docker-compose.yml:

```version: "3.8"

  &superset-volumes # /app/pythonpath_docker will be appended to the PYTHONPATH in the final container

And here is where I may be making a mistake. I thought the superset_config.py is more of an override than needing ALL the settings in it. I have only put in items I know I need to set and removed the rest.  I'm wondering if I need more in this file and that may be my issue:

```import logging
import os
import sys
 
FEATURE_FLAGS = {"ALERT_REPORTS": True, "DATASET_FOLDERS": True, "DASHBOARD_RBAC": True}
RATELIMIT_STORAGE_URI = "redis://superset-redis:6379/0"
 
MAPBOX_API_KEY = 'CUSTOMKEY'
 
from flask_appbuilder.security.manager import AUTH_DB,AUTH_LDAP
LDAP Settings not shared but working
```
And lastly the logs of the container:

Re: [D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

Posted by "echidnal (via GitHub)" <gi...@apache.org>.
GitHub user echidnal edited a discussion: Superset 6.1.0.rc2 not using postgres as meta database

Hi All,

I'm assuming I have a config wrong but can't find it.  I'm trying to spin up a more production worthy docker setup.  I've built my own image and made sure the postgres db driver is installed. And confirmed this by binding a database and data set to the same postgres db in the docker it should be using for the meta database.

The docker-compose.yml and the custom superset_config.py are being pulled in by Git to the docker server.

Based on what I am seeing -- empty postgres db AND the logs -- it seems to me that Superset is using SQLite DB and not connecting to the postgres db for the meta database.  Though I can't find a 100% way to confirm this.

I'm editing and modifying a docker-compose.yml I found on the internet.

My docker-compose.yml:

```version: "3.8"
x-superset-volumes:
  &superset-volumes # /app/pythonpath_docker will be appended to the PYTHONPATH in the final container
  #- ./docker:/app/docker

And here is where I may be making a mistake. I thought the superset_config.py is more of an override than needing ALL the settings in it. I have only put in items I know I need to set and removed the rest.  I'm wondering if I need more in this file and that may be my issue:

```import logging
import os
import sys
 
FEATURE_FLAGS = {"ALERT_REPORTS": True, "DATASET_FOLDERS": True, "DASHBOARD_RBAC": True}
RATELIMIT_STORAGE_URI = "redis://superset-redis:6379/0"
 
MAPBOX_API_KEY = 'CUSTOMKEY'
 
from flask_appbuilder.security.manager import AUTH_DB,AUTH_LDAP
LDAP Settings not shared but working
```
And lastly the logs of the container:

Re: [D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

Posted by "dosubot[bot] (via GitHub)" <gi...@apache.org>.
GitHub user dosubot[bot] added a comment to the discussion: Superset 6.1.0.rc2 not using postgres as meta database

<!-- Greeting -->
Hi @echidnal! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team.

<!-- Answer -->
The issue is that **Superset does not read `SQLALCHEMY_DATABASE_URI` from environment variables automatically**. Setting it as an environment variable in your `docker-compose.yml` has no effect — the logs confirm this with `Context impl SQLiteImpl`, meaning it's falling back to the default SQLite database [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/config.py#L198-L200).

You need to set `SQLALCHEMY_DATABASE_URI` **inside your `superset_config.py`** file. Add this to your config:

```python
SQLALCHEMY_DATABASE_URI = 'postgresql+psycopg2://CUSTOMUSER:CUSTOMPASSWORD@superset-db:5432/superset'
```

Or, if you prefer to keep credentials in environment variables and reference them from the config:

```python
import os

SQLALCHEMY_DATABASE_URI = os.getenv(
    'SQLALCHEMY_DATABASE_URI',
    'postgresql+psycopg2://CUSTOMUSER:CUSTOMPASSWORD@superset-db:5432/superset'
)
```

This is the same pattern used in Superset's own Docker reference config, which explicitly reads environment variables like `DATABASE_HOST`, `DATABASE_PORT`, etc. and constructs the URI in Python [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docker/pythonpath_dev/superset_config.py#L32-L50).

Your intuition about `superset_config.py` being an override file is correct — you only need to include settings you want to change. But `SQLALCHEMY_DATABASE_URI` **must** be set there (not just as a Docker env var) for Superset to pick it up. After making this change and restarting, you should see `Context impl PostgresqlImpl` in the logs instead of `SQLiteImpl`.

Re: [D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

Posted by "echidnal (via GitHub)" <gi...@apache.org>.
GitHub user echidnal edited a discussion: Superset 6.1.0.rc2 not using postgres as meta database

Hi All,

I'm assuming I have a config wrong but can't find it.  I'm trying to spin up a more production worthy docker setup.  I've built my own image and made sure the postgres db driver is installed. And confirmed this by binding a database and data set to the same postgres db in the docker it should be using for the meta database.

The docker-compose.yml and the custom superset_config.py are being pulled in by Git to the docker server.

Based on what I am seeing -- empty postgres db AND the logs -- it seems to me that Superset is using SQLite DB and not connecting to the postgres db for the meta database.  Though I can't find a 100% way to confirm this.

I'm editing and modifying a docker-compose.yml I found on the internet.

My docker-compose.yml:

```version: "3.8"

  &superset-volumes # /app/pythonpath_docker will be appended to the PYTHONPATH in the final container
  #- ./docker:/app/docker

And here is where I may be making a mistake. I thought the superset_config.py is more of an override than needing ALL the settings in it. I have only put in items I know I need to set and removed the rest.  I'm wondering if I need more in this file and that may be my issue:

`import logging
import os
import sys
 
FEATURE_FLAGS = {"ALERT_REPORTS": True, "DATASET_FOLDERS": True, "DASHBOARD_RBAC": True}
RATELIMIT_STORAGE_URI = "redis://superset-redis:6379/0"
 
MAPBOX_API_KEY = 'CUSTOMKEY'
 
from flask_appbuilder.security.manager import AUTH_DB,AUTH_LDAP
LDAP Settings not shared but working
`
And lastly the logs of the container:

Re: [D] Superset 6.1.0.rc2 not using postgres as meta database [superset]

Posted by "echidnal (via GitHub)" <gi...@apache.org>.
GitHub user echidnal edited a discussion: Superset 6.1.0.rc2 not using postgres as meta database

Hi All,

I'm assuming I have a config wrong but can't find it.  I'm trying to spin up a more production worthy docker setup.  I've built my own image and made sure the postgres db driver is installed. And confirmed this by binding a database and data set to the same postgres db in the docker it should be using for the meta database.

The docker-compose.yml and the custom superset_config.py are being pulled in by Git to the docker server.

Based on what I am seeing -- empty postgres db AND the logs -- it seems to me that Superset is using SQLite DB and not connecting to the postgres db for the meta database.  Though I can't find a 100% way to confirm this.

I'm editing and modifying a docker-compose.yml I found on the internet.

My docker-compose.yml:

```version: "3.8"
x-superset-volumes:
  &superset-volumes # /app/pythonpath_docker will be appended to the PYTHONPATH in the final container
  #- ./docker:/app/docker
  - superset_home:/app/superset_home

And here is where I may be making a mistake. I thought the superset_config.py is more of an override than needing ALL the settings in it. I have only put in items I know I need to set and removed the rest.  I'm wondering if I need more in this file and that may be my issue:

```import logging
import os
import sys
 
FEATURE_FLAGS = {"ALERT_REPORTS": True, "DATASET_FOLDERS": True, "DASHBOARD_RBAC": True}
RATELIMIT_STORAGE_URI = "redis://superset-redis:6379/0"
 
MAPBOX_API_KEY = 'CUSTOMKEY'
 
from flask_appbuilder.security.manager import AUTH_DB,AUTH_LDAP
LDAP Settings not shared but working
```
And lastly the logs of the container:
