Docker Deployment of Medusa + Storefront

[pmessan]

I have a setup where I deploy this storefront and a medusa backend using docker (compose). I crafted a simple dockerfile for the storefront application, which copies the sources, installs the packeges using yarn and starts the server.
The docker compose build seems to work fine (following instructions here).

I run into an issue when I try to access the storefront on port 9000, where an error is thrown, mentioning that a valid publishable key is required to proceed.

My workflow looks like this:

• build and deploy using docker compose (backend + storefront)
• login to admin panel with created user and retrieve publishable key
• update env config and restart storefront container, updating env

Which is inconvenient, and means more complex management of storefront and backend instances.

So my question is: Is there a way I can acquire this key at build time or some other way, without having to restart the storefront?
