如何使用默认集合和数据创建Mongo Docker映像？ [英] How to create a Mongo Docker Image with default collections and data?
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：

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。

谢谢来自 docker-library / mongo 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:

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