Hope this is a proper sub for asking this.

Ive been messing with docker compose, and i’m loving it. Ive also written a small script that i want to dockerize, but i want to use the environment list. What is a proper code for getting the ENV data in your script?
Ive been duckduckgo-ing (doesnt sound like the old days, does it) and i cant figure it out.

I really like using .env files, but you can hard code env vars in the compose file itself if you want.
Depends on the language the script is written in. If it’s bash/sh then it’s usually just
$VARIABLEEnvironment variables isn’t a concept of just docker, but general native app programming. So look into the docs of your language.
You need to learn how to write a Dockerfile (plenty of guides online). Not that a Dockerfile is different from a compose.yaml file (in development I use both).
The whole docker thing is rather new to me, thanks for the hints.
No problem! Let me know if you have questions. Docker was new to me a few years ago, now I work with it professionally.
Not a direct answer to your question, but I learned a bit by searching github for Dockerfile and docker-compose.yml
Thanks for the pointer.
