Service depending on secret from other service - how to share value between services?
Hi,
I have a project with 2 separate node services. service A programatically generates a unique secret (api key) first time it is build, and saves it to a postgres database.
srvice B - starts building right after service A has finished building, and service B depends on the api key from service A, to build - as the two services communicates during service B build. Normally I would pass it via environment variables, but since it is generated programatically from service A, that is not an option.
I would prefer not giving service B database access.
Currently I am exposing the api key on a endpoint in service A, and fetching it from service B with a script before build starts.
So I do have a working solution. But I would prefer not exposing secrets on an endpoint, and ideally pass the value from A to B in a smoother way.
I was hoping to be able to set a Railway project wide global value, that I can read from all other serviced - like a shared environment variable. But it is my understading that it is not possible to programatically set environment variables from within services..
I'm looking for inspiration and ideas - please suggest! π

how you do it now with an api endpoint is perfectly fine and standard practice.
heres just one example - https://www.meilisearch.com/docs/reference/api/keys#keys...

Project ID:
N/AI believe the railway API supports this (bc the public API is what runs the dashboard IIUC): https://docs.railway.app/guides/public-api
...so service A would have a railway token and API access and would set shared variable.
