Problem:
When you try to start your docker-compose based service using
docker-compose up
you see the following error message
services.my-service Additional property volume is not allowed
with a config such as
version: '3' services: mariadb: image: 'mariadb:latest' environment: - MYSQL_ALLOW_EMPTY_PASSWORD=yes - MYSQL_DATABASE=redmine volume: - './mariadb_data:/var/lib/mysql'
Solution:
You’ve mis-spelled volume:
– it always needs to be called volumes:
even if there is only a single volume:
version: '3' services: mariadb: image: 'mariadb:latest' environment: - MYSQL_ALLOW_EMPTY_PASSWORD=yes - MYSQL_DATABASE=redmine volumes: - './mariadb_data:/var/lib/mysql'
