PDNS_* options at docker-compose.yml has no effect. Why?

Question

I have docker-compose.yml file to build PowerDNS auth server:

version: '3.9'
services:
  auth:
    build:
      context: pdns/
      dockerfile: Dockerfile-auth
    environment:
      - PDNS_AUTH_API_KEY
      - PDNS_LOGLEVEL=7
      - PDNS_PRIMARY=yes
      - PDNS_LAUNCH=gpgsql
      - PDNS_GPGSQL_HOST=pgdb
      - PDNS_GPGSQL_USER=pdns
      - PDNS_GPGSQL_PASSWORD=***
      - PDNS_GPGSQL_DBNAME=pdns
    ports:
      - "1053:53"
      - "1053:53/udp"
      - "8081:8081"
    user: "1000:1000"

But when starting built container, I see that LAUNCH=gpgsql has no effect.

Notice. PowerDNS tries to load sqlite3.

When I mounted configuration file, then option is recognized:

    volumes:
      - ./volumes/pdns.conf:/etc/powerdns/pdns.conf

cat ./volumes/pdns.conf:

loglevel=7
primary=yes

launch=gpgsql
gpgsql-host=pgdb
gpgsql-user=pdns
gpgsql-password=***
gpgsql-dbname=pdns

Why environment variable - PDNS_LAUNCH=gpgsql, setted up from docker compose, was not recognized by PowerDNS?

PDNS_* options at docker-compose.yml has no effect. Why?
