Rust / Rocket environment variables

I am deploying a service which is built on Rust using Rocket and Diesel to connect to a postgres database.
I have created the postgres database and am trying to set the environment variable for the runtime to find.
In the environment I have (example not my actual settings):
value: {db={url=“postgres://”}}
When my runtime kicked off with:
(don’t want to run “cargo run --release --bin server” as it rebuilds the whole lot)
it cannot find the environment variable. Which works locally when I export it. Is there something special I need to do to get it to find my ROCKET_DATABASES environment variable?


Looks like it worked third time round. Not sure what the difference was maybe the single quotes I originally had on the value.


It’s difficult to guess what happened without having a deeper look at your code/service/error messages you received.

It’s likely that the environment variable was not available to your service at runtime.
