Firstly, create the mapping repository for mongodb:

  mkdir ~/docker/mongo_8301

  mkdir ~/docker/mongo_8301/db

  mkdir ~/docker/mongo_8301/config

  mkdir ~/docker/mongo_8301/log

Then create the launch file for starting the docker container:

 touch ~/launchers/docker_mongo_8301.sh

  vi ~/launchers/docker_mongo_8301.sh

Fill the following code into the launch file:

docker rm -f mongo_docker_8301

docker run -d -p 8301:27017 \

--name mongo_docker_8301 \

-v /home/jemaloQ/docker/mongo_8301/config:/data/configdb \

-v /home/jemaloQ/docker/mongo_8301/db:/data/db \

-v /home/jemaloQ/docker/mongo_8301/log:/data/log \

mongo --auth

Now launch docker using cmd line sh ~/launchers/docker_mongo_8301.sh. Wait till the end of image pull. Then check if mongo_docker_8301 is running correctly by executing docker ps -a | grep mongo.

Enter the inside of the container and execute mongo admin to login the default 'admin' database

   docker exec -it mongo_docker_8301 mongo admin

Now try to connect the newly launched MongoDB by Python:

from pymongo import MongoClient



client = MongoClient("mongodb://jemaloQ:123456@111.22.123.117:8301")



# print all the Databases names in Mongodb, returns empty list if no database has been created 

client.list_database_names()



# connect to the 'knowledge' database, if it does not exist, this line shall create it and then connect to it

db = client['knowledge']



# get the 'test' collection of the 'knowledge' database, if it does not exist, this line shall create it

col = db.get_collection('test')



# this item shall be uploaded to my database

item_dic = {'uid': 123, 'name': 'jemaloQ'}



# a query filter for checking whether an item with same id exists or not

query_filter = {"uid": item_dic["uid"]}



# now insert the item to 'test' collection of knowledge' database

col.update( query_filter,  {'$setOnInsert': item_dic},  upsert=True)



# now, we can see the 'knowledge' database since it is no longer empty

client.list_database_names() # => ['knowledge']
