Description
I suppose when starting application with docker compose -f compose.yaml -f local.yaml up interpolation happens before merging compose files.
Since that if compose.yaml has required environment variable which must be overrode by local.yaml, docker compose up will fail.
My expectation:
docker compose up will be applied to config from docker compose -f compose.yaml -f local.yaml config --no-interpolate.
Steps To Reproduce
Compose files:
#compose.yaml
services:
postgres:
image: postgres
environment:
POSTGRES_USER: ${PG_USER?PG_USER must be set}
POSTGRES_PASSWORD: ${PG_PASSWORD?PG_PASSWORD must be set}
POSTGRES_DB: ${PG_DB?PG_DB must be set}#local.yaml
services:
postgres:
environment: !override
POSTGRES_USER: ${PG_USER:-postgres}
POSTGRES_PASSWORD: ${PG_PASSWORD:-postgres}
POSTGRES_DB: ${PG_DB:-postgres}Merged config with no interpolation (which is what I want) docker compose -f .\compose.yaml -f .\local.yaml config --no-interpolate:
name: merge-bug
networks:
default:
name: merge-bug_default
services:
postgres:
environment:
POSTGRES_DB: ${PG_DB:-postgres}
POSTGRES_PASSWORD: ${PG_PASSWORD:-postgres}
POSTGRES_USER: ${PG_USER:-postgres}
image: postgres
networks:
default: nullWhat I get with docker compose -f compose.yaml -f local.yaml up:
error while interpolating services.postgres.environment.POSTGRES_DB: required variable PG_DB is missing a value: PG_DB must be set
