My first deploy fails on the following error. I have tried to use runtime secrets, build-time secrets (link), and passing the DATABASE_URL with a --build-arg flag. I carefully followed the Django Deployment Guide. Within my .env file I included the DATABASE_URL variable with the connection string provided during the
fly launch. I’m not sure what else to try?

.env file is used on your local development. In production, you should set the secrets with:
fly secrets set DATABASE_URL
However, if you are set up a Postgres DB during the
fly launch, the
DATABASE_URL should be set already. You can check all your secrets with:
fly secrets list
NAME DIGEST CREATED AT
DATABASE_URL cc999c17fa021988 2023-02-07T19:48:55Z
SECRET_KEY e0a6dbbd078004f7 2023-02-07T19:47:33Z
The issue happens during the build time: it’s required to have a default value for
You can set a fallback value in your Dockefile, for example:
# Set DATABASE_URL for building purposes
ENV DATABASE_URL "sqlite://:memory:" # <- Updated
# Set SECRET_KEY for building purposes
ENV SECRET_KEY "non-secret-key-for-building-purposes"
RUN python manage.py collectstatic --noinput
I’m not sure why this was not happening before, but for now, that will do it
Thank you for your reply. I had already tried the various things you are suggesting, but your post clarified a few things for me and now I have been attempting to try again while following your instructions. So I destroyed the app and the database in order to try to start fresh, but each time I execute the
fly launch command it fails to create the database, and the database gets stuck in some sort of limbo state. So I destroy it and try again, but it hasn’t worked yet.
I am hoping it will work eventually. I have found that some of the flyctl commands seem to work at some times and not at others. This has been especially true for me when trying to create or attach databases.
Thanks - it is working now! I tried some different server locations, and one of them worked. The key that got it to work was this line:
