如何通过 Docker 在 MongoDB 上启用身份验证? [英] How to enable authentication on MongoDB through Docker?
问题描述
我想为 mongodb:latest
启动一个 docker,但只允许某些用户访问某些 db(s)(即启用 --auth
).任何人都不应访问 mongodb!作为 docker 启动的一部分,我应该如何执行此操作?
I want to spin-up a docker for mongodb:latest
but allow only certain user(s) to access certain db(s) (i.e. enable --auth
). No one else should access mongodb whatsoever! How should I do this as part of the docker initiation?
顺便说一句,data directory
在启动过程中使用以下命令位于主机上:-v/my/own/datadir:/data/db
.
BTW, data directory
sits on the host by utilising the following command during initiation: -v /my/own/datadir:/data/db
.
推荐答案
如果你看看:
- https://github.com/docker-library/mongo/blob/master/4.2/Dockerfile
- https://github.com/docker-library/mongo/blob/master/4.2/docker-entrypoint.sh#L303-L313
你会注意到docker-entrypoint.sh
中使用了两个变量:
you will notice that there are two variables used in the docker-entrypoint.sh
:
- MONGO_INITDB_ROOT_USERNAME
- MONGO_INITDB_ROOT_PASSWORD
您可以使用它们来设置 root 用户.例如,您可以使用以下 docker-compose.yml
文件:
You can use them to setup root user. For example you can use following docker-compose.yml
file:
mongo-container:
image: mongo:3.4.2
environment:
# provide your credentials here
- MONGO_INITDB_ROOT_USERNAME=root
- MONGO_INITDB_ROOT_PASSWORD=rootPassXXX
ports:
- "27017:27017"
volumes:
# if you wish to setup additional user accounts specific per DB or with different roles you can use following entry point
- "$PWD/mongo-entrypoint/:/docker-entrypoint-initdb.d/"
# no --auth is needed here as presence of username and password add this option automatically
command: mongod
现在当通过 docker-compose up
启动容器时,您应该注意到以下条目:
Now when starting the container by docker-compose up
you should notice following entries:
...
I CONTROL [initandlisten] options: { net: { bindIp: "127.0.0.1" }, processManagement: { fork: true }, security: { authorization: "enabled" }, systemLog: { destination: "file", path: "/proc/1/fd/1" } }
...
I ACCESS [conn1] note: no users configured in admin.system.users, allowing localhost access
...
Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}
要添加除 root 之外的自定义用户,请使用入口点可执行脚本(放置在 $PWD/mongo-entrypoint 目录下,因为它安装在 docker-compose
到入口点):
To add custom users apart of root use the entrypoint exectuable script (placed under $PWD/mongo-entrypoint dir as it is mounted in docker-compose
to entrypoint):
#!/usr/bin/env bash
echo "Creating mongo users..."
mongo admin --host localhost -u USER_PREVIOUSLY_DEFINED -p PASS_YOU_PREVIOUSLY_DEFINED --eval "db.createUser({user: 'ANOTHER_USER', pwd: 'PASS', roles: [{role: 'readWrite', db: 'xxx'}]}); db.createUser({user: 'admin', pwd: 'PASS', roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]});"
echo "Mongo users created."
将执行入口点脚本并创建其他用户.
Entrypoint script will be executed and additional users will be created.
