如何使用默认集合和数据创建Mongo Docker映像？

本文介绍了如何使用默认集合和数据创建Mongo Docker映像？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述



我有一个脚本列表，用于创建和插入数据到MongoDB中，这些脚本将在我的Docker文件用于提供具有默认集合和数据的docker映像。



以下是我的Docker文件如下所示：

  FROM mongo ：最新
 
运行mkdir -p / data / scripts 
 
 COPY。 / data / scripts 
 
运行mongod --fork --logpath /var/log/mongodb.log --dbpath / data / db / 
 
 RUN FILES = scripts / * -create.js 
在$ FILES中为f运行;做mongo mydb $ f;完成
 
 RUN FILES = scripts / *  -  insert.js 
运行$文件中的f;做mongo mydb $ f;完成
 
运行mongod --shutdown

我尝试过不同的选项启动和停止mongod并且总是其中一个失败，当前脚本会引发以下错误：

 似乎没有使用dbpath运行的服务器：/ data / db

更新 p>

@Matt答案之后，我可以成功运行命令链，但仍然看不到我的数据库（称为my-db），集合和数据。



目前的Docker文件：

  FROM mongo：latest 
 
运行mkdir -p / data / db / scripts 
 
 COPY。 / data / db 
 
运行mongod --fork --logpath /var/log/mongodb.log --dbpath / data / db \ 
&&& CREATE_FILES = / data / db / scripts / *  -  create.js \ 
&& for f in $ CREATE_FILES;做mongo 127.0.0.1:27017 $ f;完成\ 
&& INSERT_FILES = / data / db / scripts / *  -  insert.js \ 
&&& for $ in $ INSERT_FILES;做mongo 127.0.0.1:27017 $ f;完成\ 
&& mongod --shutdown

docker构建命令的输出：

但正如我所说，我仍然看不到我的数据库中的数据库，集合和数据使用mongo shell。
另外我连接到正在运行的容器并获得了mongodb.log：

可以帮助：

解决方案

问题是信息无法保存在 / db / data ，所以我创建了一个创建自己的数据目录的解决方案。

＃使新的目录成为一个VOLUME来保持它
 VOLUME / data / db2 
 
 CMD [mongod， --config，/etc/mongodb.conf，--smallfiles]

谢谢来自 Github项目中的@yosifkit，指出卷将将数据存储在生成的图像中。我错过了文件。


I need support here to build my own mongo docker image.

I have a list of scripts to create and insert data into the MongoDB that shall be called in my Dockerfile to deliver a docker image with default collections and data.

Here is how my Dockerfile looks like currently:

FROM mongo:latest

RUN mkdir -p /data/scripts

COPY . /data/scripts

RUN mongod --fork --logpath /var/log/mongodb.log --dbpath /data/db/

RUN FILES=scripts/*-create.js
RUN for f in $FILES; do mongo mydb $f; done

RUN FILES=scripts/*-insert.js
RUN for f in $FILES; do mongo mydb $f; done

RUN mongod --shutdown

I've tried different options to start and stop mongod and always one of the two fail, the current script raise the following error:

There doesn't seem to be a server running with dbpath: /data/db

Update

After @Matt answer I could run successfully the command chain, but can't still see my database (called my-db), collections and data there.

The current Dockerfile:

FROM mongo:latest

RUN mkdir -p /data/db/scripts

COPY . /data/db

RUN mongod --fork --logpath /var/log/mongodb.log --dbpath /data/db \
    && CREATE_FILES=/data/db/scripts/*-create.js \
    && for f in $CREATE_FILES; do mongo 127.0.0.1:27017 $f; done \
    && INSERT_FILES=/data/db/scripts/*-insert.js \
    && for f in $INSERT_FILES; do mongo 127.0.0.1:27017 $f; done \
    && mongod --shutdown

The output from the docker build command:

But as I said, I still can't see the database, collections and data in my database using mongo shell.Also I connected to the running container and got the mongodb.log:

解决方案

The problem was that information could not be saved on /db/data, so I've created a solution creating my own data directory.

# Parent Dockerfile https://github.com/docker-library/mongo/blob/982328582c74dd2f0a9c8c77b84006f291f974c3/3.0/Dockerfile
FROM mongo:latest

# Modify child mongo to use /data/db2 as dbpath (because /data/db wont persist the build)
RUN mkdir -p /data/db2 \
    && echo "dbpath = /data/db2" > /etc/mongodb.conf \
    && chown -R mongodb:mongodb /data/db2

COPY . /data/db2

RUN mongod --fork --logpath /var/log/mongodb.log --dbpath /data/db2 --smallfiles \
    && CREATE_FILES=/data/db2/scripts/*-create.js \
    && for f in $CREATE_FILES; do mongo 127.0.0.1:27017 $f; done \
    && INSERT_FILES=/data/db2/scripts/*-insert.js \
    && for f in $INSERT_FILES; do mongo 127.0.0.1:27017 $f; done \
    && mongod --dbpath /data/db2 --shutdown \
    && chown -R mongodb /data/db2

# Make the new dir a VOLUME to persists it
VOLUME /data/db2

CMD ["mongod", "--config", "/etc/mongodb.conf", "--smallfiles"]

Thanks to @yosifkit from the docker-library/mongo Github project for pointing that the volume would store the data in the resulting image. I missed that on the documentation.
