当我尝试为数据库

标签: mongodb docker dockerfile

我使用的是mongo泊坞窗图片。当我尝试为新数据库创建用户和密码时,我收到错误。

这是我的Dockerfile:

FROM mongo

ENV AUTH yes
ENV JOURNALING yes    

ADD run.sh /usr/bin/run.sh
ADD set_mongodb_password.sh /usr/bin/set_mongodb_password.sh

RUN chmod +x /usr/bin/run.sh && chmod +x /usr/bin/set_mongodb_password.sh

EXPOSE 27017 28017

CMD ["/usr/bin/run.sh"]

好的,现在我的运行脚本:

#!/bin/bash

cmd="mongod"
if [ "$AUTH" == "yes" ]; then
    cmd="$cmd --auth"
fi

if [ "$JOURNALING" == "no" ]; then
    cmd="$cmd --nojournal"
fi

$cmd &

if [ ! -f /data/db/.mongodb_password_set ]; then
    set_mongodb_password
fi

fg

和我的set_mongodb_password脚本:

#!/bin/bash

USER=${MONGO_USER:-"mongo"}
PASS=${MONGO_PASSWORD:-"mongo"}
DB=${MONGO_DB:-"testdb"}

echo "=> Creating database < ${DB} > with an user < ${USER} > and password  < ${PASS} > in MongoDB"

echo "=> Creating database"
mongo $DB --eval "db.getSiblingDB('${DB}');"

echo "=> Creating user and password"
mongo $DB --eval "db.createUser({user: '${USER}', pwd: '${PASS}', roles:[ { role:'readWrite',db: '${DB}'} ]  } ) ;"
#mongo admin --eval "db.createUser({user: 'mongo', pwd: '${PASS}', roles:[{role:'readWrite',db:'$DB'}]});"

echo "=> Done!"
touch /data/db/.mongodb_password_set

echo "========================================================================"
echo "You can now connect to this MongoDB server using:"
echo ""
echo "    mongo ${DB} -u ${USER} -p ${PASS} --host <host> --port <port>"
echo ""
echo "Please remember to change the above password as soon as possible!"
echo "========================================================================"

我构建并创建了我的mongo映像,所以当我尝试连接用户和密码时,它会返回一个身份验证错误。然后我使用docker exec命令进入我的mongo容器并手动运行set_mongodb_password脚本,我收到了以下错误:

2015-08-05T06:08:50.550+0000 E QUERY    Error: couldn't add user: not authorized on pepedb to execute command { createUser: "pepe", pwd: "xxx", roles: [ { role: "readWrite", db: "pepedb" } ], digestPassword: false, writeConcern: { w: "majority", wtimeout: 30000.0 } }
    at Error (<anonymous>)
    at DB.createUser (src/mongo/shell/db.js:1101:11)
    at (shell eval):1:4 at src/mongo/shell/db.js:1101

所以,我不知道如何解决这个错误。当我使用简单的mongo图像并运行它。我可以进入容器并按步骤运行我的set_mongodb_password脚本步骤的内容,一切正常。所以我不明白问题出在哪里。也许我在配置或某些mongo参数中遗漏了一些东西。有什么帮助吗?

run.sh和set_mongodb_password.sh中有一些错误。

在脚本run.sh中,你需要在#!bash行后面添加“set -m”,因为在最后一行你使用了fg。阅读帖子quamash repo以了解“set -m”和“fg”。

在同一个脚本中,您需要调用set_mongodb_password,例如/usr/bin/set_mongodb_password.sh而不是set_mongodb_password

set_mongodb_password.sh的问题是它在run.sh之前运行,所以你需要在“#!bash”之后添加以下行来等待mongo上升:

/** This method compares 2 BigDecimal objects for equality. It takes care of null object and that was the necessity of having it.
 * To use this function most efficiently pass the possibly null object before the not null object.
 * @param pNumber1
 * @param pNumber2
 * @return boolean
 */
public static boolean isEqual(BigDecimal pNumber1, BigDecimal pNumber2)
{
    if ( pNumber1 == null )
    {
        if ( pNumber2 == null)
            return true;
        return false;
    }
    if ( pNumber2 == null)
        return false;
    return pNumber1.compareTo(pNumber2)==0;
}       

执行此操作后,您将能够执行mongo命令并创建所需的用户。
