Reading docker-compose environment variables in application code -


maybe i'm being really dumb , not understanding properly; want define docker-compose.yml file so:

web:   ...   environment:     foo: bar     bar: foo

and want expose environment variables runtime applications run inside container (i guess mapping them shell variables?).

what's best way achieve this?

i think have minor syntax issue in yml, try changing to:

web:   ...   environment:     - foo=bar     - bar=foo

you should able access variables in code expected.
