将mysql导入正在运行的docker容器中不起作用

Question

I'm probably missing the obvious, but I have been scratching my head for hours now.

My docker-compose.yml

version: '3' 
services:
  db:
    image: 'bitnami/mariadb:latest'
    container_name: mariadb
    restart: always
    ports:
      - '3306:3306'
    volumes:
      - ./mysql:/bitnami
      - ./backup:/docker-entrypoint-initdb.d
   networks:
     - default
  environment:
    - MARIADB_ROOT_PASSWORD=root
    - MARIADB_DATABASE=mydb

Works just fine. Starting up is also no problem. Once it's running I do

docker exec -i mariadb mysql -uroot -proot mydb < backup/all.sql

No error, nothing, but it's not doing the import. When I take the long way:

docker exec -it mariadb bash
mysql -uroot -proot mydb < /docker-entrypoint-initdb.d/all.sql

it works as expected. What am I not seeing?

I checked your similar commands, and so far I would say, it should work. Heres my working samples:

> echo select now() | docker exec -i mariadb mysql -uroot -proot mydb
now()
2018-04-20 21:32:38

> echo create table foo (x integer) | docker exec -i mariadb mysql -uroot -proot mydb

> echo describe foo | docker exec -i mariadb mysql -uroot -proot mydb
Field   Type    Null    Key     Default Extra
x       int(11) YES             NULL

So I would say your commands are correct. Maybe the issue is in backup/all.sql ?
