在docker集装箱中，连接到在另一个docker集装箱运行的mongodb auth由pymongo失败
我正在使用同一个泊坞窗图像运行两个名叫A和B的docker集装箱。
运行mongodb repl set服务器的A容器，我可以通过以下命令在容器和物理机器上访问它：
mongo 172.17.0.2:27020 -u admin -p admin --authenticationDatabase admin 我也可以通过pymongo在容器和物理机器上使用它：
hosts = "172.17.0.2:27018,172.17.0.2:27019,172.17.0.2:27020" extra_args = {"w": 1, "j": True} mongo_client = pymongo.MongoClient(hosts, replicaset="mongo_shard1", **extra_args) mongo_client.get_database("admin").authenticate( "admin", "admin", mechanism='SCRAM-SHA-1')
但是，在B容器上，我只能通过下面的命令访问一个容器的mongodb服务器：
mongo 172.17.0.2:27020 -u admin -p admin --authenticationDatabase admin
如果我使用上面的pymongo，我得到下面的错误：
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.7/dist-packages/pymongo/database.py", line 1048, in authenticate connect=True) File "/usr/local/lib/python2.7/dist-packages/pymongo/mongo_client.py", line 505, in _cache_credentials sock_info.authenticate(credentials) File "/usr/local/lib/python2.7/dist-packages/pymongo/pool.py", line 523, in authenticate auth.authenticate(credentials, self) File "/usr/local/lib/python2.7/dist-packages/pymongo/auth.py", line 470, in authenticate auth_func(credentials, sock_info) File "/usr/local/lib/python2.7/dist-packages/pymongo/auth.py", line 201, in _authenticate_scram_sha1 res = sock_info.command(source, cmd) File "/usr/local/lib/python2.7/dist-packages/pymongo/pool.py", line 419, in command collation=collation) File "/usr/local/lib/python2.7/dist-packages/pymongo/network.py", line 116, in command parse_write_concern_error=parse_write_concern_error) File "/usr/local/lib/python2.7/dist-packages/pymongo/helpers.py", line 210, in _check_command_response raise OperationFailure(msg % errmsg, code, response) pymongo.errors.OperationFailure: Authentication failed.
它是有线的！ 我不知道如何解决它。
Dockerfile如下：
FROM registry.cn-hangzhou.aliyuncs.com/ubuntu-14-04/ubuntu14.04 MAINTAINER yawei:xdjm562@qq.com ENV MONGODIR /data/mongodb USER root RUN mkdir /data $MONGODIR $MONGODIR/scripts COPY . $MONGODIR/scripts WORKDIR $MONGODIR/scripts RUN sh ubuntu_apt_config.sh # add mongo-org3.0 into apt list RUN apt-get install -y mongodb-org RUN apt-get install -y python-pip RUN pip install pymongo RUN sh create_key.sh mongo.key #generate base64 key by openssl COPY create_local_shard_docker.sh /usr/bin/create_local_shard_docker # create repl set and tail log to avoid container exit CMD sh create_local_shard_docker.sh && tail -f /data/mongodb/logs/mongo_shard1_27020/mongod.log
create_local_shard_docker.sh如下所示：
#!/bin/bash for port in 27018 27019 27020 do extra_opts="" if [ "${port}" = "27020" ]; then extra_opts="--other-repl-hosts 127.0.0.1:27018,127.0.0.1:27019" fi python ./create.py --ip 127.0.0.1 --no-bind --port ${port} --name mongo_shard1 ${extra_opts} done
该文件create.py太长，我认为这是没有问题的。
我不知道问题是mongo的还是docker's或pymongo的…
不pipe怎么说，还是要谢谢你。
PS：
python：2.7.6
pymongo：3.4
MongoDB的：3.0
泊坞窗：17.05.0策
