使用 Docker-Compose 在 MongoDB 上导入数据 [英] Import Data on MongoDB using Docker-Compose

问题描述

有许多站点展示了如何使用以下 docker-compose 方法将数据导入 mongodb，但我的站点没有找到 db 服务器.

如何使用 docker 为 mongo 数据库做种-撰写?https://gist.github.com/jschwarty/6f9907e2871d1ece5bde53d2559chttps://docs.codefresh.io/v1.0/docs/import-data-to-mongodb-in-composition

想知道是否发生了一些变化，使其不再起作用.

docker-compose.yml

版本:'3'服务:mongodb:图片:蒙戈命令:mongod --smallfiles端口:- 27017mongo_seed:构建:mongo-seed/.链接:- MongoDB

mongo-seed/Dockerfile

来自 mongo复制 census.json/census.jsonCMD mongoimport --host mongodb --db test --collection census --type json --file/census.json --jsonArray

mongo-seed/census.json

<预><代码>[{地理":阿拉巴马州阿比维尔市"，人口普查":2688"}]

docker-compose up

后出错

在 mongoimport 语句中，我尝试使用不同的主机名:mongodb_1、127.0.0.1、localhost.

我已经读到如果设置了 replSet 它会出现这个错误但我不会设置 replSet 除非它是默认设置在这种情况下我不知道它是如何设置的禁用它.

我也试过 mongorestore 而不是 mongoimport 但得到同样的错误.

我读到 link 在 Docker 中已弃用，可能环境变量不再起作用.不确定这是真的还是发生在这里.

有人有想法吗?

解决方案

我最终删除了 Dockerfile，在 bash 脚本中添加了命令，然后从 docker-compose 文件中调用了该脚本.在 docker-compose 文件中使用了一个脚本而不是一个命令，因为我正在导入几个文件，因此我的示例中没有显示几个命令.我需要使用 mongo:3.2.6 来完成这项工作.可能还有其他版本，但这个肯定有效.

docker-compose.yml

版本:'3'服务:mongodb:图像:mongo:3.2.6端口:- 27017:27017mongo_seed:图像:mongo:3.2.6链接:- MongoDB卷:- ./mongo-seed:/mongo-seed命令:/mongo-seed/import.sh

There are many sites that show how to import data to a mongodb using the below docker-compose method but mine is not finding the db server.

How do I seed a mongo database using docker-compose? https://gist.github.com/jschwarty/6f9907e2871d1ece5bde53d259c18d5f https://docs.codefresh.io/v1.0/docs/import-data-to-mongodb-in-composition

Wondering if something has changed making this not work any longer.

docker-compose.yml

version: '3'
services:
  mongodb:
    image: mongo
    command: mongod --smallfiles
    ports:
      - 27017

  mongo_seed:
    build: mongo-seed/.
    links:
      - mongodb

mongo-seed/Dockerfile

FROM mongo

COPY census.json /census.json

CMD mongoimport --host mongodb --db test --collection census --type json --file /census.json --jsonArray

mongo-seed/census.json

[
 {
   "Geography": "Abbeville city, Alabama",
   "Census": "2688"
 }
]

ERROR after docker-compose up

mongo_seed_1  | 2018-01-10T00:19:58.332+0000    imported 0 documents

In the mongoimport statement, I have tried using different host names: mongodb_1, 127.0.0.1, localhost.

I have read that if replSet is set it can give this error but I'm not setting replSet unless it's default in which case I don't know how it disable it.

I have also tried mongorestore instead of mongoimport but get the same error.

I have read since link is deprecated in Docker that maybe environmental variables are no longer working. Not sure if that is true or happening here.

Does anyone have ideas?

解决方案

I ended up removing the Dockerfile, adding the commands in a bash script, then calling the script from the docker-compose file. Used a script rather than one command in the docker-compose file because I'm importing several files thus several commands that are not shown in my example. I needed to use mongo:3.2.6 to make this work. There may be other versions but this one works for sure.

docker-compose.yml

version: '3'
services:
  mongodb:
    image: mongo:3.2.6
    ports:
      - 27017:27017

  mongo_seed:
    image: mongo:3.2.6
    links:
      - mongodb
    volumes:
      - ./mongo-seed:/mongo-seed
    command:
      /mongo-seed/import.sh

/mongo-seed/import.sh

#! /bin/bash

mongoimport --host mongodb --db test --collection census --type json --file /mongo-seed/census.json --jsonArray
