PostgreSql Database Configuration

Closed this issue · 4 comments

Hello guys,

I am trying to setup a Dockerfile with jupyter-scheduler that relies on the postgres to store the jobs configurations.
I am running it on an AWS ECS/Fargate, so, I'll be recreating the container after each update/upgrade/patch, so, I don't want to configure jobs again every time it occurs.

How can I store the db_url on the environment variable, or, at least, a configuration file?

I can't find anywhere in the docs.

Hello @iquirino.

You can configure the server extension via Jupyter Server configuration file. Here's a link to Jupyter Server config docs: https://jupyter-server.readthedocs.io/en/latest/other/full-config.html#config-file-and-command-line-options (in this case you would want to add c.SchedulerApp.db_url= to it).

I've opened an issue #499 to make this more clear.

Sure, at the first time I tried to use c.SchedulerApp it raised an error, so, I though it was on the wrong place and can't find where to put the config.

About the environment variables, I was able to put into python config code:

import os

#....

if 'SCHEDULER_DB_HOST' in os.environ:
    scheduler_db_host = os.environ['SCHEDULER_DB_HOST']
    scheduler_db_database = os.environ['SCHEDULER_DB_DATABASE']
    scheduler_db_port = int(os.environ['SCHEDULER_DB_PORT'])
    scheduler_db_user = os.environ['SCHEDULER_DB_USER']
    scheduler_db_pass = os.environ['SCHEDULER_DB_PASS']
    c.SchedulerApp.db_url=f"postgresql://{scheduler_db_user}:{scheduler_db_pass}@{scheduler_db_host}:{scheduler_db_port}/{scheduler_db_database}"

Thank you for your support. I'm new on python and notebooks.
