Question

我正在尝试创建一个MongoDB Docker环境。我还希望数据在重建之间保持不变。因此，我在docker-compose.yml中添加了一个卷。

这是我的docker-compose.yml

version: '3.1'

services:
  mongo:
    build:
      context: .
      dockerfile: ./docker/mongo/Dockerfile
    restart: always
    ports:
      - ${MONGO_PORT_FORWARD}:${MONGO_PORT}
    volumes:
      - ./data/db:/data/db:Z

这是我的Dockerfile

FROM mongo:latest

ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD secret
ENV MONGO_INITDB_DATABASE db

现在我运行docker-compose up，它可以完美运行。但是，当我运行docker-compose build重建图像时，下面出现错误。

Building mongo

    for f in os.listdir(current_dir):
PermissionError: [Errno 13] Permission denied: '/home/zendy/Projects/ZendyLim/GTBox/data/db/journal'

我检查了/data/db/的许可，发现它拥有999:root作为所有者。

我在这里做错了什么？我该怎么做才能使这项工作成功？

我尝试在mongodb上将用户设置为docker-compose.yml

version: '3.1'

services:
  mongo:
    build:
      context: .
      dockerfile: ./docker/mongo/Dockerfile
    restart: always
    ports:
      - ${MONGO_PORT_FORWARD}:${MONGO_PORT}
    volumes:
      - ./data/db:/data/db:Z
    user: mongodb
