Question

基本上我想在创建图像时创建用户。这样我就可以在auth模式下直接启动容器了。整个过程必须自动化。因此，我遵循了以下流程。

我正在使用mongo docker office images 3.2。我的泊坞文件

FROM mongo:3.2
MAINTAINER <name> <mail.com>
LABEL description="Mongo installation."
ADD Changeauthversion.js /home/script/
ADD createadminuser.js /home/script/
ADD createsavpuser.js /home/script/
RUN mongod --fork --logpath /var/log/mongodb.log \
&& sleep 5 \
&&mongo <Databasename> /home/script/Changeauthversion.js \
&& mongo <Databasename> /home/script/createadminuser.js \
&& mongo <Databasename> /home/script/createuser.js \
&& rm -r /tmp/mongodb-27017.sock \
&& rm -r /etc/mongod.conf.orig
ADD mongod.conf.orig /etc/
EXPOSE 5002

Docker运行文件

docker RUN -v mongoDb:/data/db -p 27018:27017 -p 28017:28017 --name mongodb1 -d platform_mongodb:v1

Changeauthversion.js

db.system.users.remove({});
db.system.version.remove({});
db.system.version.insert({ "_id" : "authSchema", "currentVersion" : 3 });

createadminuser.js

db.createCollection("test");
db.createUser({ user: "user",
pwd: "pwd",
roles: [
{ role: "userAdmin", db: "admin" },
{ role: "userAdminAnyDatabase", db: "admin" },
]
});

createuser.js

db.createUser({ user: "user",
pwd: "pwd",
roles: [
{ role: "readWrite", db: "databasename" } ,
]
});

创建图像时记录

当我启动容器并尝试登录时，mongo会抛出一个错误：找不到用户。

容器中的错误日志

:24:35.160+0000 I NETWORK  [initandlisten] connection accepted from    10.0.2.2:49713 #2 (2 connections now open)
:24:35.165+0000 I ACCESS   [conn2] SCRAM-SHA-1 authentication failed for admin on admin from client 10.0.2.2 ; UserNotFound: Could not find user admin@admin

我已经在mongo.conf文件中启用了授权。我在构建过程中将其复制到图像中。

security:
authorization: enabled

你能告诉我这是什么问题吗？为什么用户没有反映在容器中。还有另一种方法。

Answer 1

您可以通过使用您自己的mongo：3.2 image CMD指令来覆盖此问题，并绑定脚本以在图像启动后运行。您还可以创建一个shell脚本来运行容器，然后在容器启动后创建docker exec脚本。无论哪种方式 - 脚本应该在运行时执行，而不是构建时间。
